  • Dietary fiber

    serch.it?q=Dietary-fiber

    Foods rich in fibers: fruits, vegetables and grains. Wheat bran has a high content of dietary fiber.Dietary fiber or roughage is the portion of plant-derived food that cannot be completely broken down by digestive enzymes. It has two main components: Soluble fiber – which dissolves in water – is readily fermented in the colon into gases and physiologically active by-products, such as short-chain fatty acids produced in the colon by gut bacteria; it is viscous, may be called prebiotic fiber, and delays gastric emptying which, in humans, can result in an extended feeling of fullness. Insoluble fiber – which does not dissolve in water – is inert to digestive enzymes in the upper gastrointestinal tract and provides bulking. Some forms of insoluble fiber, such as resistant starches, can be fermented in the colon. Bulking fibers absorb water as they move through the digestive system, easing defecation.Dietary fiber consists of non-starch polysaccharides and other plant components such as cellulose, resistant starch, resistant dextrins, inulin, lignins, chitins, pectins, beta-glucans, and oligosaccharides.

  • Table of food nutrients

    serch.it?q=Table-of-food-nutrients

    The tables below include tabular lists for selected basic foods, compiled from United States Dept. of Agriculture (USDA) sources. Included for each food is its weight in grams, its calories, and (also in grams,) the amount of protein, carbohydrates, dietary fiber, fat, and saturated fat. As foods vary by brands and stores, the figures should only be considered estimates, with more exact figures often included on product labels. For precise details about vitamins and mineral contents, the USDA source can be used. To use the tables, click on "show" or "hide" at the far right for each food category. In the Measure column, "t" = teaspoon and "T" = tablespoon. In the food nutrient columns, the letter "t" indicates that only a trace amount is available.

  • List of diets

    serch.it?q=List-of-diets

    An individual's diet is the sum of food and drink that he or she habitually consumes. Dieting is the practice of attempting to achieve or maintain a certain weight through diet. People's dietary choices are often affected by a variety of factors, including ethical and religious beliefs, clinical need, or a desire to control weight. Not all diets are considered healthy. Some people follow unhealthy diets through habit, rather than through a conscious choice to eat unhealthily. Terms applied to such eating habits include "junk food diet" and "Western diet". Many diets are considered by clinicians to pose significant health risks and minimal long-term benefit. This is particularly true of "crash" or "fad" diets–short-term, weight-loss plans that involve drastic changes to a person's normal eating habits.Only diets covered on Wikipedia are listed.
