Dietary fiber (fibre in Commonwealth English) or roughage is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes. [1] Dietary fibers are diverse in chemical composition and can be grouped generally by their solubility , viscosity and fermentability which affect how fibers are processed in the body ...
[6] [7] [8] Soluble fibre is marketed as serving a prebiotic function with claims for promoting "healthy" intestinal bacteria. [9] Bacterial metabolism of soluble fibre also produces short-chain fatty acids like butyric acid which may be absorbed into intestinal cells as a source of food energy. [6] [7] [8] cellulose; methyl cellulose ...
Food energy is chemical energy that animals (including humans) derive from their food to sustain their metabolism, including their muscular activity. [ 1 ] Most animals derive most of their energy from aerobic respiration , namely combining the carbohydrates , fats , and proteins with oxygen from air or dissolved in water . [ 2 ]
The main action of dietary fiber is to change the nature of the contents of the gastrointestinal tract and how other nutrients and chemicals are absorbed. [8] [9] Soluble fiber binds to bile acids in the small intestine, making them less likely to enter the body; this, in turn, lowers cholesterol levels in the blood. [10]
All macronutrients except water are required by the body for energy, however, this is not their sole physiological function. The energy provided by macronutrients in food is measured in kilocalories, usually called Calories, where 1 Calorie is the amount of energy required to raise 1 kilogram of water by 1 degree Celsius. [27]
The foods within the bland diet are lower in fiber and fat, while also having a more neutral flavor and smell. These include:, Lean proteins prepared with little to no fat and with mild seasoning.
Fibres: Cellulose is the main ingredient of textiles. Cotton and synthetics (nylons) each have about 40% market by volume. Other plant fibres (jute, sisal, hemp) represent about 20% of the market. Rayon, cellophane and other "regenerated cellulose fibres" are a small portion (5%). [citation needed]
