A-Z NUTRITION GLOSSARY:

Daily Values (DV)
Daily Values are the dietary reference values that are used on all current Nutrition Facts labels. These values were determined by the FDA to best represent the minimum needs of the general population. For many nutrients, DV's will exceed your actual minimum needs, since they conservatively allow for the minimum needs of more demanding conditions, such as pregnancy or lactation. Most DV's are derived from Dietary Reference Intakes (DRI) and other recommendations made by the Food and Nutrition Board, Institute of Medicine (IOM).

For use on food labels, Daily Values formally obsolete all other previous used references, including Daily Reference Values (DRV), Reference Daily Intakes (RDI), and Recommended Dietary Allowances (RDA).

DHEA (Dehydroepiandrosterone)
Dehydroepiandrosterone or DHEA for short is a hormone made by the adrenal glands used by the body to make male (androgen) and female (estrogen) hormones; possible positive effects on mood and energy on older individuals (40+) whose production of DHEA begins to decline. As been referred to as the 'Fountain of Youth' hotmone bacause it declines rapidly as we age, and supplementation with this hormone reverses many of the ravages associated with aging. Studies show that men with the highest DHEA levels have better cardiovascular health compared to men with lower levels of DHEA.
 
Dietary fibre
Dietary fibre comes from the thick cell wall of plants. It is an indigestible complex carbohydrate. fibre is divided into two general categories: water soluble and water insoluble.

Soluble fibre has been shown to lower cholesterol. However, in many studies, the degree of cholesterol reduction was quite modest. For unknown reasons, diets higher in insoluble fibre (mostly unrelated to cholesterol levels) have been shown to correlate better with protection against heart disease in human trials.

Soluble fibres can also lower blood sugar levels, and some doctors believe that increasing fibre decreases the body’sneed for insulin - a good sign for diabetics. Insoluble fibre acts as a stool softener, which speeds digestion through the intestinal tract. For this reason, insoluble fibre is an effective treatment for constipation. The reduction in "transit time" has also been thought to partially explain the link between a high fibre diet and a reduced risk of colon cancer.
Diuretic
Diuretic is a compound that increases the flow of urine from the body. They can range from herbal teas to powerful drugs that flush out electrolytes and water. They are classed based on the location and mechanism of action in the kidneys.
 
DMAE (Dimethyl-amino-ethanol)
Dimethyl-amino-ethanol or the acronymn DMAE is a supplement reported to minimize buildup of lipofuscin (age spots) in the brain. Plays a participatory role in acetycholine synthesis. DMAE has been shown to stimulate vivid, lucid dreams, suggesting possible sleep pattern enhancement.
