      <Abstract>Dietary fibres are non-digestible carbohydrates  (cellulose, hemicelluloses, pectins, gums and mucila ges, __ampersandsignbeta;-glucans, lignin, etc.) with important physiolo gical roles in the digestive tract, as well as benefi cial  effects in maintaining optimal weight and preventing  obesity or in the prevention of noncommunicable diseases. The classification of dietary fibres is based on  the physical properties such as water solubility, fermentability and viscosity, these characteristics determining the physiological and systemic effects of fibres. &#13;
Functional roles of dietary fibres in the intestinal tract include effects on digestion and absorption,  gut motility, colonic microflora, and gastrointestinal  immunity that contribute to the systemic effects of  these food components. &#13;
The direct protective effect of dietary fibre in  the etiology of coronary heart diseases is represented by decreasing the lipids levels in plasma (soluble / viscous dietary fibers lower total cholesterol and  LDL-cholesterol, and possibly triglycerides). Dietary  &#13;
fi ber modified insulin resistance by producing short  chain fatty acids through colon fermentation, an use ful mechanism in diabetes management and increase  the bacterial conversion of bile acids, thus protecting  the intestinal mucosa from prolonged contact with  bile acids and other mutagens, an important mecha nism in preventing the risk of cancer. &#13;
High fibre foods include whole grains, some  fruits and vegetables, and dietary fi bre can be considered a marker for these foods. The recommended  daily intake of dietary fiber is 14 g fiber / 1,000 kcal /  day, respectively 14-31 g fi ber / day for children and  26-38 g fi ber / day for adolescents and adults. &#13;
Knowing the many benefits of dietary fiber  and the fact that the prevention of noncommunicable  diseases begins from childhood, it is important that  the high-fiber foods to be included in the daily diet of  children from school age.</Abstract>
