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.

Maybe, Baby, It’s Those Baby Steps That Work!

Leave a reply

Some of us at SweetWater Health recently attended the 2012 Mobile Health Conference on the Stanford University campus. The theme was “Baby Steps.” The conference was oriented to mHealth entrepreneurs, but what the speakers had to say about baby steps really applies to any human being seeking to make changes in his or her life—especially those really difficult changes, like trying to lose weight or live a healthier lifestyle.

Part of the message was that behaviors are hard to change. They’re even harder when we take on a whole raft of changes at once, which is what we usually do when we’re trying to lose weight. Here’s a sample of what many of us try to do all at once:

  • Give up anything with sugar in it
  • Reduce fat in our diet
  • Eat more fruits and vegetables
  • Cut down on or give up red meat
  • Give up or cut down on bread, cereals, rice, pasta, etc.
  • Eat smaller portions
  • Exercise for an hour a day
  • Always take the stairs instead of the elevator
  • Attend some sort of weight-loss meeting every week
  • Journal what we eat/count points/count calories or carbs every day
  • Walk at least 10,000 steps a day (in addition to exercising)
  • Some diets demand things like eating only cabbage soup, drinking a supplement twice a day instead of eating, eating only prepackaged meals, or following a complicated diet regimen based on blood type—an endless array of exotic and difficult behavior changes.

That’s a HUGE number of changes for most people! Somehow, we think we can squeeze all this in to our routine day, which includes taking care of our families, working, shopping, cooking, cleaning, and laundry. Talk about feeling stressed. And the results are predictable; we blow another weight-loss effort and feel guilty. (More stress. And if you’ve been following this blog, you know stress can make you gain and retain weight.)

The underlying message was that it’s easier to change behaviors if you just take baby steps, and when something doesn’t work, don’t keep trying to make it work; try a different baby step instead.

Not everyone can walk every day, for instance. So walk when you can, and on the days when you can’t, just try to get in 10,000 steps. If you always forget your pedometer, go up and down the stairs a few times; tomorrow, as Scarlett O’Hara famously remarked, is another day.

Another thing we tend to do is beat ourselves up if we eat something not on the “approved” list. Because we’re feeling bad anyway, we figure what the heck, in for a dime in, for a dollar, and throw the rest of the Oreos down the hatch after the first guilty cookie. Although the experts tell us truthfully that it’s better not to have temptations around the house in the first place, circumstances aren’t always ideal, and some of us have spouses and children who don’t share our issues. Look, it was just a cookie, it’s not like you stole a car. Enjoy that one cookie to the absolute maximum, and go do something else—like take a walk.

You wouldn’t begin training for a marathon by running 26 miles and 385 yards the first day. Add a step, do something else if it doesn’t work, and cut yourself some slack if you slip up. Eventually, all those baby steps add up to real progress in behavioral change.

 As we’ve mentioned before, stress is a major cause of illness—responsible for up to 90% of preventable disease, according to medical institutions like Stanford University Medical Center and Mayo Clinic. And as mentioned previously, stress can actually cause weight gain and retention, even when eating habits don’t change.

Five Things You Didn’t Know About Losing Weight

Leave a reply

We have been told for decades that losing weight was simple: eat fewer calories and exercise more so that you burn more calories than you consume.

Right.

If losing weight (and keeping it off) was simple, don’t you think that we would all be slender? But those of us who have struggled with weight loss, those of us who have lost weight only to put it all back on again—sometimes with interest—have long suspected that weight loss and sustaining healthy weight is not so simple as we have been led to believe.

Recent research has shown that there is indeed more than meets the eye when it comes to losing weight. Here are a few of those recent findings:

1. The Role of Stress. Researchers at the University of Pennsylvania found that stressed-out mice that had a history of quick weight loss due to dieting (imposed by the researchers, not by the mice) ate more high-fat foods than stressed mice that had not been made to diet. The study found that the stressed dieters had higher levels of the stress hormone corticosterone, and were more likely to exhibit “depressive” behavior than their non-dieting brethren. Even after the dieting mice were allowed to eat as much as they desired and had returned to normal weights, the changes in their brains respond to stress persisted.

Lesson Learned: while this study has not yet been tried on human subjects, it indicates there may be a link between quick weight-loss diets and a permanent change in the way the brain responds to stress. This may explain why so many people become “yo-yo” dieters, losing and gaining weight over and over again.

2.  Weight Loss Reduces Risk of Cancer. Moderate weight loss can reduce levels of inflammation that have been linked to the development of certain cancers, according to a study published in the May 1, 2012 issue of Cancer Research. The study was done on a group of post-menopausal women whose goal was to lose 10% of their body weight. During the one-year study, cancer-reactive protein levels dropped by about 36% in the women who only dieted, and about 42% in women who dieted and exercised. The researchers said that obesity drives inflammation, and inflammation drives the development of cancers, particularly cancers of the breast, lung, colon, and endometrial cancer.

Lesson Learned: Even modest weight loss will reduce the risk of some common cancers. Diet and exercise combined are the most effective ways to lose weight.

3.     Not All Calories Are Equal. A 2011 study at Harvard University showed that calories from potatoes (especially French fries, of course), red meat, and soda will cause more weight gain than the same number of calories consumed by eating fruits, vegetables, whole grains, poultry or fish. The study followed 120,000 non-obese, healthy Americans for up to 20 years.

Lesson Learned: It’s not just how much you eat—it’s also what you eat. Potatoes, sugary drinks, red meats, and refined carbohydrates (such as sugar, corn syrup, and white flour) will put on more poundage than fish, fowl, fruits, vegetables and whole grains.

4.     Sleeping Helps Lose—or Gain—Weight. The same study from Harvard found that study participants who slept less than six hours or more than eight hours a night gained more weight during each study period than those sleeping around seven hours a night. According to Michael Breus, PhD, author of “Beauty Sleep,” sleep deprivation increases levels of the hormone ghrelin, which stimulates appetite, and reduces levels of leptin, which tells us when to stop eating.

Lesson Learned: Aim at getting about 7.5 hours of sleep a night to avoid creeping weight gain.

5.     You Can Predict When Willpower Is Low. Every dieter has experienced this scenario: You are invited to a party where you know there will be lots of yummy and fattening food. You talk to yourself firmly about sticking to the vegetable crudités. But when you get there, the food is so beautiful and delicious-looking, and all home-made, too—and you wind up eating your day’s allowance of points or calories long before it’s time to go home.

How do you know when your willpower is going to let you down? If you monitor your heart rate variability (HRV), you can predict when your willpower is strong—or weak. When HRV levels are high, so is your will to resist. When HRV is low, your willpower will be low, as well. So if you monitor your willpower before that party and see it’s down in the dumps, you can give it a helping hand. You could eat before you go to the party, for instance. Or you could decide to stay home and avoid temptation altogether. HRV can be measured easily at home or on the go with SweetBeat™, an iPhone app, plus a compatible heart monitor (widely available in sporting goods stores or at http://sweetwaterhrv.com/store.html).

Lesson Learned: Willpower and HRV are tightly coupled. When HRV is low, don’t put yourself in a position where you know you will be tempted to go off the diet. The more we learn about weight loss, the more likely it is that we will be successful at it. Losing weight is hard; make it a little easier by using real data to give yourself a break.
