Wheat: The New Strychnine?

8 Replies

Everyone seems to be giving up gluten these days (and bragging about it). But we’ve been eating it for thousands of years, right? Good, whole-grain wheat is supposed to be healthy, and the government wants us to eat more of it.

Wheat sensitivities run the gamut from low-level inflammation that we don’t even notice to celiac disease, which is fatal if the sufferer does not give up eating gluten. I have friends and acquaintances who have given up wheat and lost weight effortlessly without changing anything else they are doing. They also report the disappearance of joint pain, skin rashes, muscular pain, diarrhea, and more.

Dr. William Davis, MD, author of “Wheat Belly,” makes the case that the wheat we eat today bears little resemblance to the wheat our ancestors consumed. He says that modern wheat contains the complete genomes of three different but related plants, and contains complex proteins (gluten is a protein) that ancestral varieties did not. Our gut has not evolved as quickly as wheat has due to modern genetic engineering. Also, modern wheat—uniquely among foods—has the ability to pass the blood-brain barrier, and thus can tinker with bodily mechanism and brain function in a way no other food can.

Dr. Davis cites many different studies to provide evidence that his assertions are valid. He also notes that the rise of obesity in America tracks precisely the advent of genetic modification of the wheat genome. (He doesn’t mention this, but it also precisely tracks the widespread introduction of high-fructose corn syrup that has become so ubiquitous in processed food since the 1970s.) Modern wheat, developed by Norman Borlaug, who won the Nobel Peace prize for his work on wheat, was crafted with the best of intentions in mind: alleviation of world hunger. It is a high-yield, short-growing-season dwarf wheat, and it has in fact done much toward alleviating world hunger. Apparently, it’s also making us sick.

The good doctor performed an experiment on himself to test his assertion about the pernicious effect of modern wheat versus ancestral wheat. He is highly wheat-sensitive himself. Somewhere, he managed to obtain two pounds of einkorn, probably the first form of cultivated wheat. He also obtained two pounds of modern wheat. He ground these two grains himself and made bread, using only flour, water, salt and yeast. He tried the einkorn bread. It was denser than modern bread, and had a rich, nutty flavor. He had no reaction at all. He tried the modern wheat bread—and was ill for 36 hours, nauseated and unable to focus.

Being a scientist, he also did blood tests before and after eating the breads. His blood sugar before eating either bread was 84 milligrams per deciliter (mg/dl). After eating the einkorn bread, his blood sugar was 110 mg/dl. After eating the modern wheat bread, it was 167 mg/dl. He points out that one slice of whole wheat bread will raise blood sugar significantly higher than a Snickers bar.

High blood sugar, as we all know, leads to insulin resistance, which leads to gaining weight and may eventually cause diabetes. According to Dr. Davis, we’ve been virtuously munching away on something that is making us very ill.

“Wheat Belly” is an interesting book, well written, credible, and even entertaining. It is probably an exaggeration to claim that wheat is solely responsible for everything from joint pain to schizophrenia, however. There are certainly other trends in modern life (can we blame computers?) that contribute to the surge in obesity. But if even part of what Dr. Davis claims is true (and he does have the facts and figures), giving up wheat may be part of a sensible weight-loss and weight-loss-maintenance plan—along with exercise, portion control and common sense. There are other grains that don’t present the same problems, including quinoa, sorghum, buckwheat, millet, and oats (especially oats harvested in the British Isles, where it is less likely to be contaminated by coming into contact with machinery that is also used to process wheat).

Don’t forget that other food sensitivities can play a role in weight by causing low-level inflammation that spurs fat storage and the growth of fat cells. Stress can have the same effect, so stress management is another critical aspect of successful weight loss.

Eustress, or YOU Stress?

Leave a reply

You may have heard that stress is good for you. Or you may have heard that stress is bad for you. Confusing? That’s because not all stress is equal. Hans Selye, who was one of the first researchers to focus on stress, coined the term “eustress” to refer to stress that gives you a feeling of fulfillment, success, or other positive feelings. An example of eustress is the stress you feel when competing in a contest for which you are well prepared, or when you are engaged in a challenging job that you enjoy.

Eustress enhances your functioning and is good for you because it makes you feel more alive, interested, and engaged with life.

Distress is the bad kind of stress. It can either be acute (you encounter a hostile dog that chases you) or chronic. Acute stress is the normal and helpful reaction of the body to a threat, when the body releases adrenalin and cortisol into the system, helping you to react more rapidly, run faster, and think faster. While it may leave you feeling shaken, you needed that extra oompf to escape the threat.

Chronic stress is the kind of stress imposed by modern life. The body actually doesn’t know the difference between a rabid dog and a difficult boss; any threat will cause the body to release stress hormones, and the body will react accordingly with elevated blood pressure, accelerated heart rate, and other symptoms of stress. The problem is that when a person is chronically stressed, it can cause a lot of health problems.

Selye mentions that chronic stress leads to anxiety, withdrawal and depression, but there is as much or more physical damage caused by chronic stress as psychological damage. Many respected medical institutions, including Stanford University Medical Schools, the National Institutes of Health and Mayo Clinic, estimate that as much as 90% of preventable disease is caused by stress.

This is because those stress hormones—so helpful when we are confronted by real danger—can cause damage to our tissues when they are always present in our systems. They can cause:

  • High blood pressure
  • Head and muscle aches
  • Immune system impairment
  • Asthma
  • Heart attacks
  • Breathing dysfunction
  • Constricted arteries, high cholesterol
  • Stroke
  • Weight gain
  • Digestive issues such as ulcers, irritable bowel syndrome
  • Accelerated aging

And these are just some of the physical issues created by chronic stress. Clearly, the less chronic stress we feel and the more time we spend in eustress, the better off we are.

If you are aware you are chronically stressed, then you can take steps to do something about it. But many people accept a state of chronic stress as normal. That’s the way they always feel, so they cannot recognize or accept they are in a state of continual stress. Most people are not going to proactively address a problem they think they don’t have.

So how do you determine whether or not you’re stressed? Consider whether you experience any of the physical issues mentioned above. Do you have a lot of indigestion? Do you have trouble sleeping? Do you find it impossible to lose weight, even though you eat carefully and exercise? Do you have high cholesterol or high blood pressure? These conditions may indicate chronic stress, especially if you find you have a lot of these issues.

You can also detect stress through heart rate variability, or HRV. HRV is the variation in the time interval between one heartbeat and the next.

When we think of our heart rate, we generally think of a number between 60 and 90 beats per minute. This number represents the range for the average heart rate. In fact, your heart rate changes from beat to beat. When you inhale your heart rate speeds up and when you exhale it slows down. So rather than referring to a fixed pulse of, say, 60, the heart rate will actually vary between, say, 55 and 65. HRV is a measure of this naturally occurring irregularity in the heart rate. Nearly a quarter-century of clinical research has shown that when HRV levels are high, a person experiences low levels of stress and greater resiliency. When HRV levels are low, this is an indication of greater stress and lower resiliency.

General practitioners and internists are generally not set up to measure HRV, even though it’s been studied for about 30 years and is an accepted vital sign. You can measure your own HRV using a commercially-available heart monitor such as Wahoo or 60-Beat and an app like SweetBeat™ for the iPhone, which was designed specifically to monitor stress levels using HRV.

Regardless of how you choose to detect stress, it is critical to lower stress levels in pursuit of better health. The good news is that there are many simple and inexpensive ways to reduce stress, including deep breathing, meditation, nutrition, exercise, yoga, and much more. Do the things that help you to experience eustress, and avoid the things that cause you distress. A simple concept, but one that may bolster your health and prolong your life.
