Novel fiber limits sugar absorption
This article examines the dangers of excess insulin, the role of insulin in promoting obesity, and a new dietary supplement that has been shown to reduce after-meal insulin release by 40%.
Numerous published studies reveal that excess serum insulin (hyperinsulinemia) is a major health problem. High serum insulin promotes hypertension by impairing sodium balance. Too much insulin harms the kidneys. The vascular system is severely damaged by prolonged exposure to excess insulin. By acting as a catalyst in promoting cell growth, excess insulin increases the risk and progression of certain cancers.
High serum insulin is associated with the development of abdominal obesity and the many health problems induced by abdominal obesity, including atherosclerosis and impotence. Obesity is associated with excess insulin and reduced insulin sensitivity, both risk factors for type II diabetes.
Perhaps the simplest way to evaluate the toxic effects of excess insulin is by examining its effects on human mortality. One study showed that over a 10-year period, the risk of dying was almost twice as great for those with the highest levels of insulin compared to those with the lowest.
The excess elevation of blood sugar after eating wreaks havoc in the body via multiple pathological mechanisms. Elevations in postprandial (after-meal) blood sugar, along with the accompanying insulin surge, are major contributors to the development of diabetic and age-related disorders such as heart disease, as well as diseases of the microvasculature (small blood vessels within the eyes, kidneys, and nerves).
The best fiber sources for reducing after-meal blood sugar-insulin levels, lowering cholesterol levels, and promoting weight loss are those that are rich in water-soluble fibers such as glucomannan, psyllium, guar gum, and pectin.
With the introduction of a new highly viscous fiber blend trademarked under the name PGX™, it may now be possible to achieve the multiple documented benefits of fiber by swallowing only a few capsules before each meal. The longevity potential associated with reducing after-meal glucose and insulin blood levels, lowering total cholesterol and LDL, and losing some weight is enormous.
