This article will help people who still eat bread and then wonder why they get sick to think again! It also highlights the need for gluten avoidance and adequate probiotics during infancy to set up mental health for life! Aargh! See what went wrong before we could even talk.
Most people believe that grains are a wholesome part of a healthy diet, particularly whole grains, such as whole wheat. Whole grains are also one of the relatively few foods that are allowed to make health claims on their labels, relating whole grains with a reduced risk of heart disease and certain cancers.
Unfortunately, there's a large body of evidence indicating that whole grains, and whole wheat in particular (yes even organic), can contribute to significant health problems—both physical and mental. This evidence, however, has not registered with the U.S. Department of Health and Human Services, the U.S. Department of Agriculture (USDA), or the Food and Drug Administration (FDA)—the first two of which developed the dietary guideline to consume three or more ounces of whole grain products per day.
When you begin to review the evidence stacked up against whole grains, it becomes rather self-evident that our reliance on wheat and other grains may be one of the primary culprits for the poor health of so many.
The Toxic Effects of Wheat Germ Agglutinin (WGA)
Wheat contains high amounts of wheat germ agglutinin (WGA); a glycoprotein classified as a lectin, which is largely responsible for many of wheat's ill effects. Other grains high in lectins include rice, spelt, and rye.
Interestingly enough, the highest amounts of WGA is found in whole wheat, including its sprouted form, which is touted as being the most healthful form of all... Aside from high amounts of WGA, wheat also contains a number of other potentially health-harming components, including:
Gliadin (an alcohol soluble protein component)
Gliadomorpin (exorphins, or group of opioid peptides that form during digestion of the gluten protein)
The traditional ways of addressing many of these anti-nutrients is by sprouting, fermenting and cooking. However, lectins are designed to withstand degradation through a wide range of pH and temperatures. WGA lectin is particularly tough because it's actually formed by the same disulfide bonds that give strength and resilience to vulcanized rubber and human hair.
Furthermore, because lectins are so small, and hard to digest, they tend to bioaccumulate in your body, where they can interfere with biological processes. WGA is particularly troublesome in this regard. Studies indicate it has a number of health-harming characteristics and activities:
Wheat—A Real "Downer"
One mechanism that can help explain the mysterious connection between wheat and mental health problems is the fact that wheat inhibits production of serotonin.
Neurotransmitters like serotonin can be found not just in your brain, but also in your gut. In fact, the greatest concentration of serotonin, which is involved in mood control, depression and aggression, is found in your intestines, not your brain!
Therefore, it actually makes perfect sense to nourish your gut flora with probiotic foods and supplements to maintain optimal serotonin function, as it can have a profound impact on your mood, psychological health, and behavior. This conclusion is supported by a recent animal study, which found that the absence or presence of beneficial gut microorganisms during infancy permanently alters gene expression—specifically genes and signaling pathways involved in learning, memory, and motor control.
This suggests that gut bacteria is closely tied to early brain development and subsequent behavior!
These behavioral changes could be reversed as long as the mice were exposed to normal microorganisms early in life. But once the germ-free mice had reached adulthood, colonizing them with beneficial bacteria did not influence their behavior. According to Dr. Rochellys Diaz Heijtz, lead author of that study:
"The data suggests that there is a critical period early in life when gut microorganisms affect the brain and change the behavior in later life."
The implications could be profound when you consider how many processed wheat products are consumed today, and from a very early age... Not only may our addiction to grains be fueling gastrointestinal diseases like celiac disease, along with wheat allergies, obesity, and diabetes; it may also contribute to deteriorating mental health, as well as neurodegenerative diseases like Alzheimer's.
It's definitely worth considering... especially if you're currently suffering with depression or any other psychiatric ailments.
Aside from that, ALL types of grains clearly contribute to insulin and leptin resistance, which are the primary underlying causes for most, if not all, chronic diseases—from diabetes to cancer. That alone is reason enough to restrict your intake of grains. But wheat may be of particular concern, for all the reasons discussed above.
Adversely effects gastrointestinal function by causing increased shedding of the intestinal brush border membrane, reducing the surface area, and accelerating cell loss and shortening of villi. It also causes cytoskeleton degradation in intestinal cells, contributing to cell death and increased turnover, and decreases levels of heat shock proteins in gut epithelial cells, leaving them more vulnerable to damage.
Disrupts Endocrine Function—WGA may contribute to weight gain, insulin resistance, and leptin resistance by blocking the leptin receptor in your hypothalamus. It also binds to both benign and malignant thyroid nodules , and interferes with the production of secretin from your pancreas, which can lead to digestive problems and pancreatic hypertrophy.
Excitotoxicity-- Wheat, dairy, and soy contain exceptionally high levels of glutamic and aspartic acid, which makes them all potentially excitotoxic. Excitotoxicity is a pathological process where glutamic and aspartic acid cause an over-activation of your nerve cell receptors, which can lead to calcium-induced nerve and brain injury. These two amino acids may contribute to neurodegenerative conditions such as multiple sclerosis, Alzhemier's, Huntington's disease, and other nervous system disorders such as epilepsy, ADD/ADHD and migraines.
The Gut-Brain Connection
Most people fail to realize that your gut is quite literally your second brain, and actually has the ability to significantly influence your:
As you can see from the listing of toxic influences above, wheat germ agglutinin (WGA) can damage both your gut and your brain in various ways. But damage to your gut can also, by virtue of the gut-brain connection, alter your mind, mood and behavior all by itself... Anxiety and depression are actually part of the signs and symptoms of celiac disease, for example.
The gut-brain connection is well-recognized as a basic tenet of physiology and medicine, so this isn't all that surprising, even though it's often overlooked. There's also a wealth of evidence showing gastrointestinal involvement in a variety of neurological diseases. With this in mind, it should also be crystal clear that nourishing your gut flora is extremely important, from cradle to grave, because in a very real sense you have two brains, one inside your skull and one in your gut, and each needs its own vital nourishment.
Your gut and your brain are actually created out of the same type of tissue. During fetal development, one part turns into your central nervous system while the other develops into your enteric nervous system. These two systems are connected via the vagus nerve, the tenth cranial nerve that runs from your brain stem down to your abdomen. This is what connects your two brains together, and explains such phenomena as getting butterflies in your stomach when you're nervous, for example.
Your gut and brain work in tandem, each influencing the other. This is why your intestinal health can have such a profound influence on your mental health, and vice versa. As a result, it should be obvious that your diet is closely linked to your mental health. Furthermore, it's requires almost no stretch of the imagination to see how improper nutrition can have an adverse effect on your mood and subsequently your behavior.
"If, as hypothesized, neuroactive peptides from grain glutens are the major agents evoking schizophrenia in those with the genotype(s), it should be rare if grain is rare. To test this, we analyzed the results of our clinical examinations (e.g., kuru) and observations of anthropologists on peoples consuming little or no grain.
Only two overtly insane chronic schizophrenics were found among over 65,000 examined or closely observed adults in remote regions of Papua New Guinea and Malaita , Solomon Islands, and on Yap , Micronesia. In preneuroleptic Europe over 130 would have been expected.
When these peoples became partially westernized and consumed wheat, barley beer, and rice, the prevalence reached European levels. Our findings agree with previous epidemiologic and experimental results indicating that grain glutens are harmful to schizophrenics."
"Individuals with recent-onset psychosis and with multi-episode schizophrenia who have increased antibodies to gliadin may share some immunologic features of celiac disease, but their immune response to gliadin differs from that of celiac disease."
