background: different studies have shown that inadequate and unbalanced intake of nutrients including micronutrient and macronutrient, have negative effects on exercise performance and optimal ability; besides, it decreases physical efficiency in athletes. the present study aimed to assess the nutritional status and body composition of female athletic students in isfahan university of medical s...

OBJECTIVES To highlight the differences between the food list required in a food-frequency questionnaire (FFQ) to rank people by their intake and the food items that contribute to absolute intake, and to discuss possible applications. METHODS We conducted a nutritional survey among 1173 adults using an adapted 24-hour recall questionnaire. STATISTICAL ANALYSIS To develop an FFQ, we analysed...

Digestible energy (DE), metabolizable energy (ME) and net energy for maintenance (NEm) values of a set of fourteen diets were measured in six adult sows fed at and below their maintenance energy level. The efficiency of ME for NEm was estimated from heat production (HP) measurements (indirect calorimetry) at these different feeding levels. HP was partitioned between HP due to physical activity,...

It is well known that any quantitative (energy and protein levels) and qualitative (nature of the diet, nutrient dynamic) changes in the feeding of animals affect metabolism. Energy expenditure and feed efficiency at the whole-body level, nutrient partitioning between and within tissues and organs and, ultimately, tissue and organ characteristics are the major regulated traits with consequences...

The definition of sustainable food and nutrition security involves four principal domains. Foods and food patterns need to be nutrient-dense, affordable, culturally acceptable, and sparing of the environment. Each domain has its own metrics. Nutrient density is measured in terms of nutrients in relation to calories. Affordability is measured in terms of calories and nutrients per unit cost. Cul...

Peanut is a legume crop that belongs to the family of Fabaceae, genus Arachis, and botanically named as Arachis hypogaea. Peanuts are consumed in many forms such as boiled peanuts, peanut oil, peanut butter, roasted peanuts, and added peanut meal in snack food, energy bars and candies. Peanuts are considered as a vital source of nutrients. Nutrition plays an important role in growth and energy ...

Exact knowledge of the nutrient requirements of premature infants is critically important for the prevention of postnatal growth failure and for improved neurodevelopmental outcome. Methods whereby nutrient requirements can be estimated fall into two categories, factorial methods and empirical methods. Each have their advantages and disadvantages. The factorial methods provide estimates of requ...
