Dairy products: how they fit in nutritionally adequate diets.

Individual diet modeling with linear programming recently provided evidence that plant-based products, fish, and fresh dairy products consumption should be increased in the French population to reach nutrient-based recommendations. The aim of our study was to estimate the number of portions of the different milk-based food categories fitting into nutritionally adequate diets. Starting from the diet observed for each adult in the 1999 French Enquête Individuelle et Nationale sur les Consommations Alimentaires survey (n=1,171), an isocaloric nutritionally adequate diet was modeled that simultaneously met a whole set of nutrient constraints (based on nutrient recommendations) while deviating the least from the observed diet food content.

Nutrient profiling schemes: overview and comparative analysis.

Nutrient profiling is a discipline aimed at classifying foods based on their nutritional composition. So far, several profiling schemes have been proposed for varied purposes world-wide. Primary aim to inventory the main profiling schemes that have been developed so far (both applied and not) and to summarise their main aspects.

Trophic status of the small intestine in young and aged rats: modulation by a yogurt-supplemented diet.

Among the multifactorial causes of undernutrition in old age, gastrointestinal mucosa altered function and resulting specific malabsorption are the most relevant. Despite numerous studies that have dealt with the effects of aging on the digestive tract of mammals, results showed discrepancies in terms of proliferation and biochemical aging small intestine events. However, the slowing-down of the maturation process and the poor adaptation of metabolism and intestinal function are obvious and there is evidence that protective mechanisms are impaired with age and contribute to affecting the trophic activity and related systemic homeostasis.
