Forbidden Foods on the Paleo Diet
I don't like troublemakers. And I have noticed a lot of them these days, most hang out in grocery stores, restaurants and even in my own kitchen! You can't see them with the naked eye, but they are there, hiding in whole grains, beans and potatoes. If you don't want these troublemakers in your diet they can be quickly disposed of by adopting "paleo" approach to health.
The Paleo Diet is probably the most natural and right way that we should eat. Not only have we veered away from this diet that has basically stood the time of evolution, but our society is moving further and further away from foods that made and kept us well.
The core of Paleo Diet: eschews grains, beans, and potatoes, sugars, and modern vegetable oils in favour high-quality meat, fish, eggs, and vegetables.
The Problem With Grains
And, while the fibre contained in whole grain products should reduce the insulin response to these carbohydrates by slowing their absorption from the intestine, the grains in these products are usually so finely ground that most of them rank about evenly on the glycemic scales with refined grain products.
As a result, most whole grain products raise our glucose and cause as much insulin release as refined grain products. Insulin stimulates the synthesis and storage of fat, so eating these products can cause weight gain.
Morphine-Like Substances in Whole Grains
Unfortunately, they also slow metabolism. And, like morphine, they are addictive and create cravings that cause us to eat more foods that are high in carbohydrates - and to gain more weight!
High carbohydrate foods also create comfort by increasing the production of the brain's feel good neurotransmitter, serotonin.
Whole Grains Contain Lectins
While the inflammatory effects of lectins are becoming increasingly well known, another characteristic of lectins that causes weight gain is their ability to mimic hormones, particularly the hormone insulin.
As previously mentioned, insulin is a hormone that stimulates fat synthesis and storage. It does this by binding to a specific site, called a receptor, on the surface of fat cells. This action allows glucose or blood sugar to enter the fat cells where it is converted to fat.
Unfortunately, certain lectins, particularly the lectins found in wheat grain, can also bind to insulin receptor sites. By attaching to the insulin receptor, lectins give the fat cell the same message that insulin gives; that is, to take up glucose from the blood stream and convert it to fat.
However, unlike insulin, which is released from the cell, lectins remain attached to the insulin receptor indefinitely. This gives the fat cell a continuous message to take up glucose and make fat.
In addition to stimulating the synthesis and storage of fat by binding to insulin receptors, wheat lectins can also bind to the receptor for cholecystokinin . CCK is a hormone that is involved in appetite control.
When lectins bind to CCK receptors they increase your appetite causing you to feel hungry and eat more.
Phytates Bind to Minerals
Iron deficiency, for example, reduces the oxygen carrying capacity of the blood making you feel tired and unable to exercise, while calcium deficiency can lead to osteoporosis, the leading cause of hip and spinal fractures in older women and men.
And a deficiency of zinc can lead to impairment of the immune system with an increased susceptibility to infection and poor wound healing.
Ironically, since phytates are removed during the refining process, whole grain products create more mineral deficiencies than refined grain products.
Are Grains Making You an Exorphin Junkie?
It is reasonable to propose that in people whose intestinal digestion of these foodstuffs is incomplete, exorphins are absorbed and have the effect of a small dose of an opiate drug. For example, patients who take wheat bran and find their constipation gets worse. On the plus-side, the well-known effect of pleasant somnolence after a meal is probably also due to morphine-like activity.
When you combine the ability of whole grain products to: :
Cause the release of large amounts of insulin,
Increase your appetite
Send a continuous message to your fat cells to synthesize and store fat
Slow your metabolism and create cravings
It is not difficult to understand why weight loss programs that include a large amount of whole grain products usually fail.
From a diabetic's point of view, don't you owe it to yourself to start cutting down or eliminating grains in your diet to enhance your health?
