11 unhealthy foods you should avoid

11-unhealthy-foods-margarineMisconceptions about which foods are “healthy” and which foods aren’t often originate in the barrage of advertising most of us are subject to in this technology-oriented age.

Capitalizing on the current buzz in nutritional trends is an integral part of tending that bottom line for food corporations, but it can be confusing for consumers.

These 11 foods are presented as healthy choices, but if you’re eating them without knowing these facts, you may be sabotaging your desire for strength and wellness.

1. Whole Wheat Bread

Most of the bread labeled “whole wheat” is made with grains that have been pulverized into a fine flour that will raise blood sugar levels just as fast as bread made with white flour. In fact, the glycemic index (GI) of many whole wheat breads is similar to white breads. (1)

The darker appearance of breads marketed as whole wheat sometimes comes from added colorants (2), and remember that “whole grains” lose their wholeness when they’ve been over-processed.

Even if you’re getting the real deal, keep in mind that the wheat available today has lower nutritional value than it did in about a half-century ago, when some of the good properties were sacrificed through gene manipulation designed to increase crop yields. (3)

2. Agave Nectar

Since everyone knows sugar is bad, the market has been flooded with alternative sweeteners. Billed as a “natural” sweetener, agave nectar is a popular choice, but it’s even worse than sugar.

The fructose content of agave nectar is about 85%, much higher than sugar and high fructose corn syrup.

Agave nectar rates lower on the GI scale than sugar and doesn’t spike blood sugar levels in the same way sugar does; that’s because the liver processes fructose, and overloading this vital organ by ingesting foods high in fructose content can lead to serious metabolic disorders. (4)

The natural qualities of agave nectar are destroyed in processing, and while “nectar” makes it sound attractive, it’s really a syrup.

3. Organic and Vegan Junk Foods

Just because a processed food is made with organic ingredients doesn’t mean it’s good for you.

For example, organic raw cane sugar hits the bloodstream with the same punch as white table sugar, and it delivers the same nutritional value: zip.

Vegan foods designed to replace the animal-based counterparts are similar. If you have any doubts, check the ingredient label on a package of vegan bacon.

4. Commercial Salad Dressings

Many people depend on commercially prepared salad dressings to get down their quota of vegetables, which are incredibly healthy but often bland, especially when eaten raw.

Most salad dressings on supermarket shelves are made with ingredients that will cancel out the benefits of your vegetables.

Common ingredients include trans fats, sugar, chemical additives, and processed vegetable oils high in omega-6 fatty acids, which most of us already eat far too much of.

You’re better off using your own healthy ingredients to make a dressing at home, even if it’s just a simple olive oil and vinegar drizzle.

5. Brown Rice Syrup

Another sweetener marketed as “natural” and “healthy,” brown rice syrup is made from cooked rice that’s been exposed to enzymes to break down the starch into simple sugars.

It’s pure glucose and will spike blood sugar in a flash. (5)

All the nutrients contained in rice are lost in processing, so it’s full of empty calories, just like table sugar.

Recent analyses of brown rice syrup pulled off grocery shelves indicates a small percentage products are contaminated with arsenic. (6)

Skip the brown rice syrup and check into other alternative sweeteners with actual health benefits, like xylitol, stevia and erythritol.

6. Sweet Drinks Like Fruit Juice and Sports Drinks

Many commercial fruit juices are loaded with chemicals and flavorings that have nothing to do with fruit.

Even if you’re a careful label-reader and believe fruit juice must be healthy since it comes from fruit, keep in mind the sugar content of fruit juice is comparable to any sugar-sweetened drink. (7)

When the fiber is removed from fruit, it speeds up the assimilation process, jacking up blood sugar.

While sports drinks usually contain a bit less sugar and the focus is on maintaining electrolyte balance through adding salts lost through perspiration, they were developed for athletes.

While everyone who works out with any enthusiasm is likely to break a sweat and perhaps sustain it for a while, most people are better off drinking water.

7. Packaged Low-Carb Foods

Numerous studies over the last decade confirm that following a low-carb diet is a great way to improve overall health and lose weight. (8, 9)

Marketing packaged junk foods labeled “low-carb” is an excellent route to higher profits for manufacturers.

While indulging in the occasional low-carb junk food treat won’t set you back when you’re adhering to a low-carb diet, all you have to do is read the label to see that these products are usually loaded with chemicals and artificial ingredients.

8. Processed Foods Labeled “Fat Free” and “Low Fat”

The myth that saturated fat is bad for you has been thoroughly disproven by science in recent years, but food manufacturers are still cleaning up on products tailored to appeal to misled consumers.

Added sugar is the most common strategy used to compensate for the missing fat that made the food taste good in the first place.

Saturated fat won’t damage your health, but eating excessive amounts of sugar will really mess up your metabolism. (10, 11)

While there may be some exceptions, most low fat and fat free foods are heavy on sugar content.

9. Margarine

When people believed saturated fat caused heart disease, food manufacturers were quick to offer margarine as a substitute, with products often labeled “heart healthy.”

Margarine was originally loaded with trans fats; while that’s changed in modern times, the replacement is highly processed vegetable oil laced with chemicals to make it taste and look like real butter.

Data from the Framingham Heart Study confirms that margarine-eaters are more likely to die of heart disease than those who eat butter. (12)

10. Gluten-Free Junk Foods

A full third of Americans reported they were trying to avoid gluten in 2013. (13)

Many people find gluten in the diet causes a variety of health issues (14), and the demand for gluten-free products continues to grow.

The replacement ingredients in these foods may be gluten-free, but they’re also often devoid of nutrients, and the refined starches will spike blood sugar in exactly the same manner as products containing wheat.

Choosing foods that are naturally free of gluten is a better idea.

11. Vegetable Oils

Studies have shown that eating vegetable oils like grapeseed and canola can reduce blood cholesterol levels in the short term (15), but it’s important to remember high cholesterol isn’t a disease, it’s a risk factor.

If you’ve been following advice to include highly processed vegetable and seed oils in your diet, you should know several controlled trials show these products raise the risk of being diagnosed with cancer and developing heart disease. (16, 17, 18)

Dropping the numbers on a single risk factor like cholesterol levels may not be worth the price. Stick with butter, olive oil and coconut oil.

Summary: There are many products besides the ones covered here that are promoted as “healthy” even though they’re not. Your bottom line is more important than net profits of giant corporations; know what you’re buying and how it will affect your body so you can make informed food choices.

Insulin resistance symptoms and treatment

insulin

Insulin resistance occurs when cells no longer respond to the message delivered by insulin. The pancreas secretes more insulin to try to fix the situation, and excess circulating insulin can build up to create a condition called hyperinsulinemia.

Insulin is a hormone involved in the regulation of many vital processes in the body. Problems with this important hormone can lead to a number of common modern health issues.

When cells no longer respond to insulin the way they’re designed to, it’s called insulin resistance; a study conducted in 2002 indicated nearly a third of Americans may be suffering from this condition. (1)

Among certain groups, the problem is even more widespread.

Estimates for the number of obese women with insulin resistance run at 70%, and obese children and young adults may clock in as high as 33%. (2, 3)

In many cases, lifestyle modifications can result in dramatic improvements in this condition. Read on to find out about causes and how to overcome insulin resistance.

Insulin 101

Secreted by the pancreas, insulin controls nutrients in the blood; its main job is to regulate blood sugar levels, but it also plays a role in the metabolism of protein and fat.

The carbohydrates in meals increases the amount of sugar in our bloodstreams, and pancreatic cells sense the change and release insulin, which circulates in the blood, signaling cells to pick up sugar.

Cells follow orders, taking up sugar for energy use or storage, and blood sugar levels drop; but if this process isn’t working, blood sugar levels stay high, leading to imbalances that can cause harm or even death when levels are extremely elevated.

This can go on for a long time, with blood sugar and insulin levels continuing to rise; the issue can eventually lead to a diagnosis of type 2 diabetes, a serious disease that affects nearly one in ten people worldwide. (4)

Note the distinction between insulin resistance and insulin sensitivity:

  • Insulin resistance means your insulin sensitivity is low
  • Insulin sensitivity means you are sensitive to the message insulin is delivering to cells

So insulin sensitivity indicates normal function, where cells respond to the message to uptake sugar from the blood, while insulin resistance is the opposite circumstance that results in high blood sugar levels.

Causes of Insulin Resistance

Researchers believe one of the main triggers for insulin resistance is elevated levels of free fatty acids in the blood. (5)

The build-up of fatty acid metabolites and fats inside muscle cells, for example, may block signals sent by insulin; the term for this build-up is intramyocellular fat. (6)

This type of fat accumulation is due to eating more calories than necessary and packing around excess weight. Obesity, weight gain and overeating are all associated with developing insulin resistance. (7)

Belly fat that can build up around the organs is thought to release fatty acids into blood, along with inflammatory hormones leading to insulin resistance. (8)

People who aren’t overweight can also be insulin resistant, but it’s not as common. (9)

Other potential causes for insulin resistance include:

  • High fructose intake from a diet high in sugar (added sugar, rather than whole fruit) (10)
  • Inflammation and high levels of oxidative stress (11)
  • Sedentary lifestyle (12)
  • Imbalances in gut bacteria (13)

Social factors, heredity and race may also play a role in establishing risk factors for insulin resistance; studies show Asians, blacks and Hispanics are more likely to develop this condition. (14)

Are You Insulin Resistant?

If you’re overweight and have a lot of belly fat, you may be insulin resistant. Besides having high fasting blood sugar levels, there are several other ways to determine if you’ve developed insulin resistance.

HOMA-IR is a fairly accurate blood test used to estimate resistance from insulin and blood sugar levels. Oral glucose tolerance tests are another method; after an oral dose of glucose is given, blood sugar levels are tested over the following few hours.

Acanthosis nigrans is a skin condition where dark spots appear on the skin, sometimes indicating insulin resistance.

Low levels of HDL cholesterol (the good kind), as well as high blood triglyceride measurements, are two other possible signs of the condition.

Insulin resistance is present in two extremely common health conditions: type 2 diabetes and metabolic syndrome.

Symptoms

Metabolic syndrome, also called insulin resistance syndrome, is a combination of risk factors associated with heart disease, diabetes, and other health problems, including: (15, 16)

  • Elevated blood pressure (hypertension)
  • Central obesity (high amounts of belly fat)
  • Elevated blood sugar
  • Low HDL cholesterol
  • High measurements of blood triglycerides

Insulin resistance is associated with type 2 diabetes as well; cells no longer respond to insulin, and eventually the pancreas cannot keep up with the demand for more. An insulin-deficiency develops. (17, 18)

Stopping this process may result in preventing type 2 diabetes and metabolic syndrome; people with these conditions are 93% more likely to get heart disease. (19)

Other chronic diseases associated with insulin resistance include:

  • Fatty liver disease (non-alcoholic) (20)
  • Polycystic ovarian syndrome (PCOS) (21)
  • Alzheimer’s disease (22)
  • Cancer (23)

Treatment

Insulin resistance does not have to lead to serious health issues. In many cases, simple lifestyle choices can improve or reverse the condition.

Here are ten changes you can make to positively influence insulin sensitivity:

  1. Increase the amount of exercise you get (24)
  2. Reduce belly fat
  3. Quit smoking tobacco (25)
  4. Eat less sugar and stop drinking sweetened beverages, especially sugary sodas
  5. Base your diet on whole foods, including fish and nuts
  6. Get adequate omega-3 fatty acids (26)
  7. Add supplements like berberine and magnesium (27, 28)
  8. Improve the quality of your sleep (29)
  9. Manage stress (30)
  10. Practice intermittent fasting (31)

Eating a low-carb diet has also been shown to improve health markers linked with type 2 diabetes and metabolic syndrome, partly through positive effects on insulin resistance. (32, 33)

While this list isn’t intended as medical advice, note that the suggested actions are all associated with good health habits.

Summary: Evidence shows insulin resistance can play a role in raising risk factors for many modern chronic diseases; making lifestyle choices that help prevent or correct this vital issue may be one of the most positive actions you can take to enjoy good health.

How to prevent diabetes

low-carb-diabetesMore than 400 million people around the world are affected by the growing epidemic of diabetes. (1)

Complications associated with this complex disease can be greatly reduced by good management of blood sugar levels, and following a low-carb diet has been shown effective for this purpose. (2)

While a healthy body can efficiently break down dietary carbohydrates into tiny units of glucose that become blood sugar, this process doesn’t work properly for diabetics.

We’ll take a close look here at how low-carb diets can be used to manage blood sugar levels.

Diabetes 101: How Food Affects Blood Sugar

When blood sugar levels rise after eating the consumption of carbohydrates, insulin is produced by the pancreas. This hormone is necessary for blood sugar to be taken into cells and used to fuel body processes.

Blood sugar stays within a fairly narrow range during the day when everything works right; this is vital, since both low and elevated blood sugar levels can lead to serious harm.

The two most common types of diabetes are type 1 and type 2; people have been diagnosed with these disorders at all ages.

  • Type 1 diabetes is characterized by an autoimmune process that destroys pancreatic beta cells that produce insulin; to facilitate glucose entering cells, type 1 diabetic patients inject insulin several times daily for blood sugar regulation. (3)
  • Type 2 diabetic patients produce enough insulin at first, but cells grow resistant to the hormone, resulting in high blood sugar levels; the pancreas pumps out more insulin in an attempt to restore balance in the bloodstream, but eventually beta cells can’t keep up with the demand. (4)

Of the three macronutrients in food (carbohydrates, fats and proteins), carbs have the most significant impact on blood sugar levels.

When diabetic patients eat large quantities of carbohydrates, they may need to take bigger doses of diabetic medication or insulin to manage blood sugar.

Trials and Studies

A number of studies show that low-carb diets can be very effective in treating diabetes. (5, 6, 7, 8)

Before the discovery of insulin in 1921, placing diabetic patients on a low carb diet was standard treatment for the disease. (9)

Those who follow the diet usually have good long-term results. In one study, type 2 diabetic patients following a low-carb diet were closely observed for six months, then re-evaluated three years later. Those who stuck with the plan had well-controlled blood sugar. (10)

Type 1 diabetic patients had similar results over a 4-year study period using a restricted carbohydrate diet. (11)

In some studies, dramatic improvements in both blood sugar levels and weight were noted by restricting carb intake to less than 20 grams daily. (12)

Other research indicates comparable results can be achieved by limiting carbs to 20% of dietary intake, or between 70 and 90 grams daily. (13)

Since everyone has a unique response to carbohydrates, the best way to pinpoint optimal carb amounts is measuring blood sugar levels an hour or two after meals.

Nerve damage begins to occur at 140 mg/dL (or mmol/L), so monitoring levels with a blood glucose meter can help patients determine optimal carbs for their bodies; some may need to keep carbs at 6 per meal, while others may be able to handle up to 25 or 30.

Carbohydrates and Food Choices

Fiber in plant foods is not broken down into glucose; sugar and starch content jacks up blood sugar.

Seeds, nuts, blueberries and vegetables are the preferred sources of carbohydrates because they are nutrient-dense and high in fiber.

When you’re looking at carb content of various foods, subtracting fiber carbs leaves a carb count that is called “net,” or “digestible” carbs.

For example, a cup of cauliflower delivers 5 carbs, but 3 are from fiber, so net carbs are only 2.

Inulin is a type of prebiotic fiber that has been shown to positively affect blood sugar levels and other health markers in diabetic patients. (14)

Be wary of sugar alcohols such as erithritol, mannitol and xylitol, which may be used to sweeten diet products like candy; these can raise blood sugar levels in diabetic patients.

For example, if carbs from mannitol are subtracted from total carb counts found on product labels, the result may be inaccurate. (15)

Also, fitness trackers may be a good resource for tracking intake.

These are examples of foods you can eat freely, some of which will also help make certain you’re getting plenty of protein:

  • Eggs, meat, poultry and fish
  • Cheese, avocados and olives
  • Low-starch vegetables
  • Quality fats and oils, such as coconut oil, olive oil, butter, cream cheese and sour cream

Depending on your level of carb tolerance, these foods can be eaten in smaller quantities:

  • Starchy vegetables high in fiber, such as acorn, hubbard and butternut squash (a cup or less)
  • Cottage cheese (½ cup) or Greek yogurt (1 cup)
  • Berries (1 cup)
  • Peanuts and nuts (1 to 2 ounces)
  • Chia or flax seed (1 to 2 tablespoons)
  • Dark chocolate at 85% cocoa (up to 30 grams)
  • 5 ounces of liquor or 4 ounces of dry wine

Lowering carb intake will usually drop insulin levels, causing the kidneys to release both water and sodium. (16)

Low-carb foods that can help replace lost sodium include olives and broth, and adding a little salt to meals is fine unless you’re on a low-sodium diet as part of a plan for treating kidney disease, congestive heart failure or hypertension; in cases like these, consult your physician.

Foods such as these are higher in carbs and can raise blood sugar levels:

  • Sweetened drinks like juice and soda; beer
  • Fruit, except for berries
  • Milk
  • Legumes, including beans, lentils and peas (greens beans and snow peas are exceptions)
  • Yams, potatoes, sweet potatoes and taro
  • Grains (including corn), bread, cereal and pasta
  • Candy, deserts, baked goods, ice cream, etc.

If you take insulin or other medications to control diabetes, it’s vital to speak with your doctor before adopting a low-carb diet.

Blood sugar levels can fall dramatically in short periods of time when carb intake is reduced, and adjustments to medications may be necessary to prevent hypoglycemia, or dangerously low blood sugar levels.

Some patients have been able to stop taking medications altogether when following a low-carb diet. (17)

Other methods proven to help manage blood sugar levels include:

  • Getting good quality sleep (18)
  • Tegular resistance training and aerobic exercise (19)
  • Reducing stress (20)

Many diabetics have had good results in dropping blood sugar levels by following a low-carb diet. Be sure to speak with your doctor before making dietary changes.

Summary: Restricting carbohydrates can be effective in reducing the risk of complications for patients with type 1 and type 2 diabetes; blood sugar levels may also be improved, and some patients are able to decrease or discontinue medications.

7 sleep deprivation effects that will ruin your life

sleepSleep deprivation is a condition that can cause fatigue, sleepiness during the day or extreme weight loss or weight gain.

Getting plenty of sleep is equally important for good health as eating quality food and exercising.

Lifestyles in the modern Western world have taken a toll on sleep habits. People sleep fewer hours each night than they did in past times, and overall quality of sleep has been negatively impacted by environment.

Here are seven reasons why sleep deprivation could be ruining your life:

1. Sleep Deprivation Can Lead to Increased Appetite and Weight Gain

Short sleep duration is a strong risk factor for obesity. Those who don’t sleep enough weigh significantly more than those who get adequate rest. (1, 2)

Children who are chronically short on sleep are at an even higher risk for developing obesity than adults.

In a massive review of multiple studies, data indicated that children are 89% more likely to become obese when they don’t get enough down time. Adult rates for obesity ran at 55%. (3)

Fatigue can decrease motivation to exercise, and hormonal changes related to the lack of sleep are two factors believed to influence weight gain.

Sleep deprivation jacks up levels of the hunger hormone, ghrelin, stimulating appetite when the real problem is not enough rest. Leptin, a hormone that suppresses appetite, is present at lower levels for the sleep-deprived. (4, 5)

If you’re not sleeping enough, you’re likely to have a bigger appetite and eat more calories during the day.

2. Decreases Cognitive Performance

Concentration and productivity are improved when the body and brain have been rested. (6)

Medical interns are known for running on very little sleep; one study compared the performance of interns operating on a traditional schedule to those who worked schedules allowing them more sack time.

Interns who slept less made 36% more serious medical errors than the ones who slept more. (7)

Another study measured the negative effects of sleep deprivation on brain function in comparison to the way alcohol intoxication affects thinking processes, finding the two had similar effects. (8)

Children and adults alike are more proficient in problem-solving exercises when they have had enough sleep. (9, 10)

3. Your Body Performs Worse

Researchers studied the athletic performance of basketball players in relation to sleep habits, and results indicated those who got adequate sleep could react and move faster, incorporated greater level accuracy in the game, and enjoyed a higher level of mental wellbeing. (11)

A study with nearly 3000 older women indicated a lack of sleep resulted in functional limitations during exercise, as well as poor overall performance. Not only did the women walk more slowly, but they couldn’t grip as well, and weren’t as good at following through with independent activities. (12)

4. Raises the Risk of Developing Chronic Diseases

The length and quality of sleep you get can have a significant effect on a number of risk factors for developing chronic diseases.

An analysis of 15 separate studies showed that people who slept 7 to 8 hours each night were much less likely to suffer a stroke or be diagnosed with heart disease than those who spent less time in bed. (13)

Researchers tracking various effects of sleep deprivation found insulin sensitivity decreases when people don’t sleep enough. (14, 15)

When healthy young men were only allowed to sleep four hours each night for six nights in a row, they developed signs of pre-diabetes. Insulin levels returned to normal after a full week of adequate sleep. (16)

Other studies have also shown poor sleep is associated with problems in regulating blood sugar. If you sleep less than 6 hours a night, your risk of developing type 2 diabetes is higher. (17, 18)

5. Increases Inflammation Levels

The loss of sleep has been clearly linked with increased inflammation, activating undesirable markers and measuring both cell damage and inflammation.

Studies indicate digestive tract disorders such as inflammatory bowel diseases are much more common for people who don’t sleep enough. (19, 20)

Patients diagnosed with Crohn’s disease suffer twice the rates of relapse when they’re sleep-deprived. (21)

Medical evaluations to predict long-term outcomes for patients diagnosed with inflammatory diseases may take information about quality and duration of sleep into consideration in the future. (22)

6. Decreases Your Immune System

Even the loss of a few hours of sleep can negatively impact immune system function, making you more vulnerable to bacteria and other pathogens in your environment. (23)

During a two-week study, more than 150 healthy participants were given nasal drops containing the virus that causes the common cold.

Subjects who slept seven hours or less each night came down with colds at three times the rate of those who spent eight hours or more between the sheets. (24)

If you’re catching a cold often, try adding some extra sleep time.

7. Increases Depression

Depression and other mental health challenges have been strongly associated with sleep deprivation and poor quality sleep.

Nine out of ten patients being treated for depression say they don’t get enough good sleep. (25)

Death by suicide occurs more frequently with patients who report poor sleep habits. (26)

Subjects being treated for obstructive sleep apnea and insomnia suffer depression at a much higher rate than people who get adequate sleep. (27)

The ability to interact with others is also impacted by a lack of quality sleep; researchers say we’re more likely to miss important social cues and are not able to process emotional information as well when we are tired.

We may not be as alert to facial expressions indicating anger or happiness, resulting in blunders or misinterpretation of information normally gathered from watching others during conversation. (28, 29)

Many people working to improve health focus mostly on nutrition and exercise. It’s absolutely necessary to consider these vital components, but sleep is often sacrificed in the interest of fitting it all in.

Leading a full life can be stimulating and exciting, but if you don’t get enough sleep, you may be sabotaging yourself on other levels.

Summary: Sleep deprivation sucks. Schedule and protect your down time to make sure you’re at the top of your game physically and mentally. You’ll be faster, smarter, happier, and more socially adept, as well as less likely to catch a cold or be diagnosed with something more serious.

Gluten sensitivity symptoms and diagnosis

gluten-sensitivityGluten sensitivity is condition in which certain individuals experience adverse reactions to eating foods containing gluten, such as wheat. (1)

Health professionals find the problem highly controversial, since 1% or less of the population suffers from celiac disease, a severe form of gluten intolerance classified as an autoimmune and digestive disorder that damages the small intestine. (2)

Many people who don’t have full-blown celiac disease have problems with eating gluten, and a 2013 survey indicates a full third of Americans actively avoid or try to cut back on gluten. (3)

Wheat is the most common source of gluten in the diet, along with other cereal grains like barley, rye, and spelt. Gluten is made up of a family of proteins, the two most prominent of which are gliadin and glutenin.

Researchers believe gliadin is the protein most people have problems with. (4)

The word gluten originated from descriptions of how these proteins affect the texture of foods containing them: adding water to flour causes proteins to cross-link and create a sticky texture much like glue. (5)

This is what holds bread together, as well as allowing it to rise when heated due to trapped gas molecules inside the dough.

Let’s take a look at what gluten sensitivity is, and whether or not you need to be concerned about it.

Gluten sensitivity diagnosis

Recent research has separated and classified a number of disease conditions related to wheat and gluten, the best-known of which is celiac disease. (6)

When celiac patients consume gluten, their immune systems mistake the proteins for invaders and mount an attack; structures of the gut wall are also targeted, and the resulting damage is what makes the issue an autoimmune disorder. (7)

Severe cases are on the rise, and most people who have celiac disease don’t realize it. (8)

Those who suffer from gluten sensitivity don’t experience this autoimmune reaction, but symptoms can be similar, with problems of a digestive nature as well as non-digestive reactions. (9, 10)

A small number of people estimated at less than 1% are actually allergic to wheat, which is a different issue than gluten sensitivity. (11)

A bad reaction or sensitivity to gluten has been associated with a number of diseases and disorders; some of these are cerebral ataxia, schizophrenia, depression, autism, type 1 diabetes and Hashimoto’s thyroiditis. (12, 13, 14, 15, 16, 17)

While the links with these disorders don’t mean that gluten intolerance caused them, it appears that the condition may make symptoms worse, and a diet free of gluten often leads to improvements.

All the recent attention to gluten and gluten sensitivity has led to intense research on the subject, but the mechanism is still not clearly understood; scientists believe the immune system is involved, as well as genetics. (18)

Symptoms

A lab test for gluten sensitivity is not available, and it’s usually diagnosed by ruling out other conditions. Here is a proposed protocol for establishing sensitivities: (19)

  1. When people experience negative symptoms after eating foods containing gluten, they are placed on a gluten-free diet.
  2. If symptoms disappear, gluten is added back into the diet.
  3. If symptoms recur, celiac disease and wheat allergies are ruled out with lab tests.
  4. A blinded gluten challenge test can be used to confirm diagnosis.

Common symptoms of gluten sensitivity include:

  • Chronic fatigue
  • Stomach pain
  • Flatulence and bloating
  • Diarrhea
  • Bone and joint pain
  • Headaches
  • Depression
  • Weight loss
  • Eczema and Erythema (skin conditions, including rashes and redness)

Other mysterious symptoms that may not be directly related to digestion also appear to be linked to gluten intolerance, including various neurological disorders and skin conditions besides those mentioned above. (20)

Good data on how prevalent gluten intolerance is doesn’t exist. While some studies estimate the percentage is likely in the low ranges, such as less than 0.5%, others speculate it could be as high as 6%. (21)

Adults, especially those in middle age, and women in all age groups, appear to suffer from gluten intolerance at higher rates. (22)

A recent trial conducted on gluten sensitivity may shed new light on the subject; 37 people diagnosed with irritable bowel syndrome (IBS) who believed they were gluten intolerant ate a diet low in FODMAPs and given isolated gluten. (23)

FODMAPs are Fermentable Oligo- Di-Mono Saccharides and Polpyols; these short chain carbohydrates cause digestive problems for many people, especially in those with IBS.

When people can’t digest FODMAPs, this matter ends up feeding gut bacteria in the intestines, resulting in bloating, gas and diarrhea. An estimated 14% of Americans are affected by IBS. (24)

Foods containing FODMAPS include legumes, some fruits and vegetables, grains, milk and sugar alcohols like mannitol and xylitol.

In this study, participants followed a diet low in FODMAPs and did not experience digestive disturbances when they took isolated gluten, leading researchers to believe the self-reported gluten sensitivity was actually a reaction to FODMAPs.

The results indicate that gluten may not be the biggest offender when it comes to symptoms suffered by patients with IBS; instead, foods containing FODMAPs may be the main issue.

Researchers concluded that “wheat intolerance” or “wheat sensitivity” may be a more accurate label for the problem in some cases. (25) Avoiding wheat is still the best solution for those with this type of sensitivity.

Other recent studies suggest that modern strains of wheat can be much more aggravating than the ancient varieties, such as Kamut and Einkorn. (26)

Recap

Gluten sensitivity is a complex issue that will continue to be the subject of intense study to find clear answers for the question of intolerance.

Despite the fact that some health professionals are skeptical on the subject, many scientists and doctors, some of whom specialize in gastroenterology, are convinced gluten sensitivity is a valid and growing concern.

If you believe you’re sensitive to gluten, waiting for confirmation from ongoing research is certainly not necessary, but keep the results from the FODMAP study mentioned above in mind. You may want to extend your range of experimentation to check out this possibility.

The nutrients found in wheat are available in other foods; you’ll get the best nutritional value if you avoid processed foods when choosing suitable substitutes for wheat, since these are just junk foods even though they’re gluten-free.

Summary: Gluten sensitivity isn’t a problem for everyone, and if wheat doesn’t cause problems for you, there’s no need to avoid it just because it’s trendy to do so. For anyone with established issues related to wheat consumption, going gluten-free can bring considerable relief and improved health.

Everything you need to know about celiac disease

gluten-celiacCeliac disease is an autoimmune disorder that occurs in some people where the ingestion of gluten leads to damage in the small intestine.

Nearly a third of Americans are trying to eliminate gluten from their diets (1) because they believe it is negatively impacting their health.

Public awareness about the potential effects of gluten has grown rapidly over the past few years with the spotlight on study results showing how the proteins most commonly ingested through wheat and other grains may be undermining our desire to feed ourselves in a way that feels good and keeps us healthy.

You’ve probably noticed more gluten free options in restaurants and supermarkets, and you may even be avoiding gluten yourself, or at least wondering if it may be causing problems for you.

There’s a lot of conflicting information floating around about gluten, so let’s get the basics straight first.

A protein composite found in wheat, rye, barley, spelt and certain other grains, gluten contains both glutenin and gliadin. Most people with gluten sensitivities have adverse reactions to gliadin.

The term gluten is derived from the word “glue,” which accurately describes how these proteins act when combined with liquid. Gluten facilitates the elasticity of bread dough, holding the separate components together as it rises, bakes and falls fragrantly away from the knife or slicer.

Only 1% of the population experiences gluten sensitivities and reactions severe enough to classify as celiac disease, with symptoms ranging from anemia and fatigue to nutritional deficiencies and a doubled risk of death from other diseases. (2)

Many suffering from celiac disease go undiagnosed; some don’t have symptoms, but experience a host of seemingly random health issues.

Here’s what happens with those who suffer from celiac disease:

  • Gluten in the digestive tract may be mistaken by the immune system as a foreign substance
  • A defensive attack is mounted to protect the body from invaders
  • In celiac reactions, the immune system attacks both gluten proteins and an enzyme in digestive tract cells called tissue transglutaminase
  • Escalated response can turn into an autoimmune disease that results in deterioration of the intestinal walls, causing significant perforations in the gut
  • Undigested food substances leaking into the bloodstream from damaged intestinal tissue can lead to further damage, spiral the body into a cyclic reaction of heightened immune response
  • Energy and resources are diverted to handle the emergency, weakening the system and creating ongoing vulnerabilities and malfunctions

Since the standard American diet focuses heavily on foods containing gluten, much more than 1% of the population may be experiencing adverse effects from everyday fare. (3)

If you’re dealing with unexplained symptoms, you may be wondering if gluten is a problem. Some sources report that between 6 – 8% may be gluten sensitive based on gluten antibodies found in the blood. (4)

It is also possible to test stool samples for gluten antibodies, which can show indications of intestinal damage as well. (5)

True celiacs are twice as common in the elderly population, but up to 40% of us carry genes designated as HLA-DQ2 and HLA-DQA, both of which increase the likelihood of developing gluten sensitivities. (6)

Those diagnosed with celiac disease diagnosis are not the only ones whose health can be devastatingly impacted by gluten. Some medical problems often associated with gluten intolerance or sensitivity include:

  • Stomach aches and/or bloating
  • Irritable bowel syndrome
  • Diarrhea
  • Intestinal inflammation
  • Fatigue
  • Joint or bone pain

Since there is not yet a definitive testing procedure to identify sensitivities, the best way to pinpoint gluten tolerance is to eliminate all foods containing gluten from your diet and pay attention to how you feel.

After a week or two, reintroduce gluten and see how you react. Be alert for any and all changes.

According to researchers at Harvard Medical School, the brain and gut are intimately connected. (7)

Discovering and addressing gluten sensitivity early can help protect brain function and cut your risk of developing serious neurological disorders.

Gluten sensitive idiopathic neuropathy refers to neurological illnesses that can be caused or made worse by gluten intolerance.

In one study of 53 patients suffering from neurological symptoms of unknown origin, more than half tested positive for gluten antibodies in the blood. (8)

Cerebellar ataxia, which damages the cerebellum, is associated with cases of gluten intolerance, and results in problems with speech and motor controls that affect balance and movement. (9)

Several studies show strong links between gluten consumption, sensitivities and cerebellar ataxia; many patients show improvement when they follow a gluten-free diet. (10, 11, 12)

Autistic patients may benefit from avoiding foods with gluten; behavioral problems can decrease, allowing a greater level of normal interaction with others and the environment. (13, 14)

Some schizophrenic patients show significant improvement when gluten is removed from their diets. (15, 16, 17)

Epilepsy has long been treated with ketogenic diets, which are very low in carbohydrates and affect electrical activity in the brain. Gluten intolerance could also be part of the equation; researchers have found some patients experience fewer seizures in the absence of gluten-containing foods. (18, 19, 20)

If you’ve ever had trouble keeping your hands out of the bread basket when you know you’ve had enough, you won’t be surprised to learn wheat is hot on the heels of sugar for triggering food-related addictive responses.

Breaking down gluten in a test tube yields peptides than can activate opioid receptors. (21)

Scientists studying these processes with animals believe there’s a possibility these gluten exorphins may find their way into the bloodstream (perhaps through damaged intestinal walls) and result in addiction. (22, 23)

An autoimmune disorder is any set of circumstances that cause the body to attack part of its own system. This is what happens with celiac disease, the most severe reaction in cases of gluten intolerance.

Autoimmune diseases affect about 3% of the population, (24) jacking up the risk for developing other immune disorders like arthritis, lupus, type 1 diabetes, multiple sclerosis and Hashimoto’s thyroiditis. (25)

Summary: Even if full-blown celiac disease isn’t on your radar, gluten sensitivity or intolerance can wreak havoc on a whole spectrum of body systems and result in serious health problems. No two reactions may be quite alike, but if you suspect gluten may be causing problems for you, don’t wait to explore the possibilities.
