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. 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. 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 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. 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. 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> <AbstractLanguage>English</AbstractLanguage> <Keywords>dietary fibre, functional fibre, high-fiber foods, noncommunicable diseases</Keywords> <URLs> <Abstract>https://revista-medicina-scolara.ro/ubijournal-v1copy/journals/abstract.php?article_id=9259&title=ROLES OF DIETARY FIBRES IN THE PREVENTION OF NONCOMMUNICABLE DISEASES</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References>1.
