	Dietary Fibre - MSN Encarta
		Dietary Fibre, remains of plant cell walls; a complex mixture of carbohydrates that resist digestion in the intestinal tract and are therefore apparently of no value in the diet.
		Fibre will bind a proportion of the bile salts (and cholesterol itself, which is also secreted in the bile), so that they are excreted in the faeces rather than being reabsorbed, thus causing more cholesterol to be used for bile salt synthesis.
		Bile salts have also been implicated in the development of cancer of the large intestine—if they are bound to dietary fibre rather than free in solution, they cannot interact with the intestinal wall in the same way to promote the development of tumours.

	Dietary Fibre and Resistant Starch (Site not responding. Last check: 2007-10-29)
		Dietary fibre is therefore usually defined as food components that resist digestion by human enzymes in the small intestine and that pass into the large intestine where they may or may not be fermented by gut bacteria.
		Insoluble fibre, found in wheat and rice bran, is resistant to fermentation in the gut and is excreted in the faeces.
		The type and amount of dietary fibre is a factor which seems to impact on the glycaemic index of carbohydrates and in this way contributes to determining the overall rate of absorption of carbohdyrate and hence their impact on blood glucose levels.

	Physiological Effects of Dietary Fibre (Site not responding. Last check: 2007-10-29)
		Dietary fibre, however, can be roughly divided into those which are rapidly fermented, such as oligosaccharides, those which are more slowly fermented, such as gums, and those which are hardly fermented at all, such as wheat bran.
		Dietary fibre has also a role in changing the consistency of the stool by increasing the water content and the plasticity, and increasing stool frequency.
		Purified dietary fibres may reduce acutely the absorption of some vitamins and minerals by binding or entrapping them in the small intestinal lumen, however, there is little evidence that population groups consuming nutritionally adequate diets rich in high fibre foods, such as vegetarians, have any problems with vitamin or mineral deficiencies (170,171).

	Dietary Fibre Supplements
		Dietary fibre is the indigestible part of fruits and vegetables.
		Fibre slows the rate at which your stomach empties, increasing feelings of "fullness." This is part of the way in which your body helps you to control the amount you eat and avoid over eating, which in turn helps to lower blood sugar levels.
		Fibre supplements of insoluble fibres such as wheat bran, or soluble fibres such as oat bran or pectin, are known to increase digestion time by slowing the movement of food and stomach acid into the intestines, which can help accelerate the healing of duodenal ulcers by reducing length of exposure to stomach acids.

	Dietary fibre, weight gain and risk factors for cardiovascular disease
		Fibre intake was inversely associated with waist-to-hip ratio in both white adults (lowest quintile 0.813; highest quintile 0.801) and fl adults (lowest quintile 0.809; highest quintile 0.799).
		Fibre was consistently associated with insulin levels, weight gain and other cardiovascular disease risk factors, whereas fat was not, which raises the interesting possibility that fibre may play a greater role in determining cardiovascular disease risk than either total or saturated fat.
		This study did not examine the effects of soluble versus insoluble fibre and the extent to which the reduced risk of cardiovascular disease observed with diets high in fruit, vegetables, wholegrains, etc. is attributable to the high fibre content and/or the substances within them, such as antioxidants and phytochemicals.

	The Hindu : Every fibre counts
		Dietary fibre is neither absorbed by the stomach enzymes nor assimilated in the small intestines where other carbohydrates such as starch and sugars are digested.
		These types of dietary fibre are often recommended for the management of certain types of diabetes since when ingested, they are found to reduce postprandial glucose levels in blood.
		Fibre can be incorporated in the daily diet by substituting whole grain cereals for refined foods, Increased intake of fruits and vegetables, preferences of whole pulses and legumes to split dhal.

	Jamaica Gleaner News - The virtues of dietary fibre - Wednesday \| March 22, 2006
		Dietary fibre is that part of food substances that is resistant to chemical digestion.
		There is some strong evidence which indicates that water-soluble fibre found in food such as peas, beans, lentils, apples, mangoes, citrus fruits, prunes, oatmeal and oat bran can help to prevent cholesterol and saturated fat from entering the blood stream because of its gel-like property.
		Fibre should be increased in the diet gradually, as too much too soon can cause digestive problems in some individuals such as bloating, flatulence, diarrhoea and even constipation, as water should be increased as fibre increases.

	Mango cookies could boost dietary fibre intake, says research
		Despite the mounting evidence for the benefits of dietary fibre, a survey by Columbia University showed the average intake in the US was about 12.5 grams a day, well short of the 32 grams of fiber per day recommended by the US National Fiber Council.
		The antioxidant activity of the fibre concentrate was measured using the DPPH free-radical scavenging assay and found to be higher than fibres extracted from guava, a fruit considered suitable as an antioxidant dietary fibre.
		The soluble dietary fibre content for the MDF cookie was found to be almost six times that of the control (6.0 versus 1.3 grams per 100g).

	CSIRO Dietary Fibre guidelines (Fact Sheet)
		Dietary fibre (or "roughage") is a complex mixture of different components including the carbohydrates cellulose, hemicellulose, gums, mucilages, pectins and the non-carbohydrate - lignin.
		Fibre chemistry is a recently developed science - the metabolic effects of the isolated and purified fractions of fibre are yet to be adequately defined.
		Dietary fibre is found in foods of plant origin only - cereals, vegetables, fruit, dried peas, beans, lentils and nuts.

	[No title]
		Dietary fibre is derived from solely from plant cells, mostly from the plant cell wall.
		Dietary fiber is not a single entity but in fact consists of many substances, as we shall see, and each has different properties.
		Fibre from fruit and vegetables is less effective in increasing fecal bulk since much of their fibre consists of rapidly fermentable pectin and the less microbial promoting cellulose.

	Information on dietary fiber
		Dietary fiber or dietary fibre (alternate names: roughage, bulk, diet-fiber) is a complex of substances of cell walls of plants which are not digested and not absorbed in a human's digestive tract.
		Dietary fiber helps to get rid of redundant kilograms because it absorbs water, by what it expans and fulfills stomach decreasing hunger and also delaying the moment in which food leaves stomach.
		Soluble dietary fiber (pectins) is decomposed to tricarboxylic fatty acids which are responsible for inhibition of cholesterol biosynthesis in liver.

	Cholesterol Lowering Effects of Dietary Fibre
		Dietary fibre is a collective term for a variety of plant substances that are resistant to digestion by human gastrointestinal enzymes.
		For each type of fibre studied, participants were a mixture of healthy (in 21 studies), hyperlipidemic (in 30 studies) or diabetic (in 14 studies) men and women.
		One gram of soluble fibre decreased total cholesterol by 0.045 mmol/L and LDL cholesterol by 0.057 mmol/L (95% confidence intervals 0.054 to 0.035 and 0.070 to 0.044 respectively).

	Dietary fiber - Wikipedia, the free encyclopedia
		Dietary fibers are the indigestible portion of plant foods that move food through the digestive system, absorbing water.
		One of the most versatile sources of dietary fiber is the husk (hull) of seeds from psyllium grain (Plantago ovata), a fiber source with clinically demonstrated properties of lowering blood cholesterol when chronically included in human diets.
		Although many researchers believe that dietary fiber intake reduces the risk of colon cancer, one study, conducted by researchers at the Harvard School of Medicine of over 88,000 women, did not show a statistically significant relationship between higher fiber consumption and lower rates of colorectal cancer or adenomas.

	Dietary fibre increases cancer risk
		Diseases blamed on a lack of dietary fibre include: intestinal diseases such as cancer of the colon, appendicitis, constipation and irritable bowel syndrome as well as coronary heart disease, diabetes, obesity, deep vein thrombosis, varicose veins, hiatus hernia and gallstones.
		Dr Hugh Trowell, another strong advocate of dietary fibre, confirmed this in 1974, saying that 'a serious confusion of thought is produced by referring to the dietary fibre hypothesis as the bran hypothesis, for many Africans do not consume cereal or bran but remain almost free of constipation, irritable bowel syndrome and diverticular disease'.
		He concludes that the effects of excessive intakes of dietary fibre on calcium, iron and zinc absorption would be particularly undesirable for infants, children and young adolescents, and recommends that dietary fibre intakes in those groups should be separated from those for the general adult population and given on a body-weight basis.

	Dietary Fibre
		Dietary fibre is the roughage found in cereals, fruit and vegetables.
		The outer fibre layer is often removed in food processing by milling, peeling, boiling or extracting and so people are often not eating enough insoluble fibre.
		Soluble fibre is found in oats, legumes (peas, kidney beans, lentils), some seeds, brown rice, barley, oats, fruits (such as apples), some green vegetables (such as broccoli) and potatoes.

	The Benefits of Eating Fibre
		Traditionally, fibre was considered to be an inert part of food, passing undigested from mouth to anus and expelled intact in the stool.
		Soluble fibre includes pectin, gums (such as guar), betaglucans, some hemicellulose and other compounds and is found in oats, legumes (peas, kidney beans, lentils), some seeds, brown rice, barley, oats, fruits (such as apples), some green vegetables (such as broccoli) and potatoes.
		Soluble fibre in oat bran, legumes (dried beans of all kinds, peas and lentils), and pectin (from fruit, such as apples) and forms in root vegetables (such as carrots) is considered especially helpful for people with either form of diabetes.

		Low fibre intake has been associated with an increased risk of a variety of cancers (including breast and colon cancers), and I think it would be a very rare HSI member who was not aware that dietary fibre helps maintain a healthy digestive system.
		Dietary factors were assessed in interviews that showed that higher fibre intake reduced the risk of heart attack by well over 25 percent.
		Some people add fibre supplements to their diets, but Dr William Campbell Douglass, has warned against using these supplements and eating fibre-enriched food, stating that the total effect they may have on the human body is still unknown and potentially dangerous.

	DIETARY FIBRE
		Dietary fibre is a component of all plant materials.
		Fibre is classed as either soluble or insoluble, depending on whether or not it dissolves in water.
		Insoluble fibre — sometimes referred to as roughage or bulk — is the best type for relieving constipation because it increases stool volume, as well as the movement of material through your digestive system.

	ADVANCE Pet Foods
		Fibre is a term that has been used for many years to describe the most complex and least definable component of foods of plant origin, thus it encompasses a diverse group of polysaccharides, mucilages and phenolic compounds.
		However, all plant derived dietary fibres share the feature (in contrast with digestible polysaccharides such as starch) that the linkages joining their structural units together are resistant to degradation by mammalian digestive enzymes.
		Whilst categorisation of dietary fibre into soluble and insoluble fractions gives some guidance to expected physiological effects within the gastrointestinal tract, the relative impact of the two fractions depends on a range of factors including dietary source and processing prior to ingestion.

	Fibre Facts: Dietary Fibre and a Healty Lifestyles
		Well, fibre plays a key role in the body’s fight against disease and is an essential component of a healthy diet.
		In areas of the world where people eat a diet rich in fibre, studies have suggested the rate of colon cancer is significantly lower than that of fibre-poor cultures.
		With no fibre in your diet, blood sugar fluctuates wildly as the sugars from your food are immediately absorbed into the bloodstream.

	Dietary fibre could reduce inflammation, CVD
		Insoluble fibre intake was associated with a 68 per cent reduction in CRP levels, while soluble fibre was linked to a 42 per cent reduction.
		The mechanism of how dietary fibre could reduce inflammation is not clear, say the researchers.
		Another explanation is that soluble fibre act as prebiotics by boosting conditions for bacteria in the intestinal tract, improving gut health, and subsequently preventing inflammation.

		Dietary fibre is the defining component in whole-grain and bran ingredients.
		Dietary fibres can draw water away from other ingredients (eg, gums, wheat gluten) interfering with their functionality.
		The dietary fibre component of brans is much higher — corn bran contains approximately 85 per cent insoluble dietary fibre, while oat bran, of beta-glucan fame, typically contains 24 per cent total dietary fibre as a blend of both soluble and insoluble fibre fractions.
