Minerals and why we need them
Chromium RDA 50-200ug.
Hypoglycaemia is the term for low blood sugar, and hyperglycaemia is the term for high blood sugar. It is much more undesirable to have a high blood sugar condition because elevated blood sugar levels over time can cause damage to the eyes and kidneys. On the other hand, repeated low blood sugar episodes can create other undesirable problems with mood and metabolism.
A biologically active form of chromium participates in glucose metabolism by enhancing the effects of insulin. Insulin is secreted by specialised cells in the pancreas in response to increased blood glucose levels, for example, after a meal. Insulin binds to insulin receptors on the surface of cells, activating those receptors and stimulating glucose uptake by cells. Through its interaction with insulin receptors, insulin provides cells with glucose for energy and prevents blood glucose levels from becoming elevated. In addition to its effects on carbohydrate (glucose) metabolism, insulin also influences the metabolism of fat and protein.
A decreased response to insulin or decreased insulin sensitivity may result in impaired glucose tolerance or type 2 diabetes, also known as non-insulin dependent diabetes mellitus. Type 2 diabetes is characterised by elevated blood glucose levels and insulin resistance. Diets high in simple sugars compared to diets high in complex carbohydrates increase urinary chromium excretion in adults.
Several studies suggest that chromium needs may be greater in individuals who exercise regularly, also it was found that elderly subjects dying from coronary artery disease had no chromium in the aorta. Tissue levels of chromium decline with age.
Healthy people supplemented with chromium showed increased HDL-cholesterol (good cholesterol) levels, while their triglycerides and LDL-cholesterol levels decreased.
Studies in chromium supplementation have been shown to improve stamina in deficient individuals and chromium uptake may be enhanced when given at the same time as vitamin C.Chromium's role within the nervous system
The brain and nervous system are highly dependent on adequate blood glucose levels for efficient operation and any blood sugar issues can have a detrimental effect on their functionality.Symptoms associated with chromium deficiency
Poor blood sugar regulation (diabetes and hypoglycaemia) - disturbed fat and protein metabolism - alcohol intolerance - impaired growth - high blood pressure - arteriosclerosis - weight loss - fatigue - eye problems (opaque cornea, near sightedness, glaucoma) - irritability - frustration - weakness - cold hands - unexplained weight loss - depression - impaired serotonin production.Other Minerals
