Energy requirements for space flight
Article Abstract:
A review of data on nutritional requirements during space flight and space residence is presented. The microgravity environment of space travel has a profound effect on the metabolism and physiology of astronauts. It has been shown that energy utilization on earth and in space seems to be equal. However, lean body mass is catabolized despite adequate energy intake of astronauts during flight. Further research on predictors of energy requirement, energy source, the influence of exercise and micronutrients is needed to ensure the health of space crews during flight.

An evolutionary perspective enhances understanding of human nutritional requirements
Article Abstract:
Modeling ancestral dietary pattern is vital in understanding current human nutritional needs. A comparative study indicates that an ordinary Paleolithic diet is analogous to presently recommended diets in East Asia, the Mediterranean, and the one designed by the American Health Association in terms of minimal saturated fatty acid content. Stone Agers' consumption of vegetable and fruits is three times more than the US. Micronutrient intake is higher yet of moderate extent whereas protein and fiber are considerably higher than the present diet.

Estimation of the niacin requirements for tilapia fed diets containing glucose or dextrin
Article Abstract:
The adequate amount of niacin needed in diets with either glucose or dextrin for juvenile hybrid tilapia was estimated. Niacin-deficient diets resulted in fish with skin, fin, mouth, and gill lesions. Dextrin as carbohydrate source was found to result in better growth of tilapia. Analysis of weight gain by broken-line regression showed that dietary niacin levels of 26 mg/kg in glucose-based diets and 121 mg/kg in dextrin-based diets are adequate for maximal growth of rapidly growing tilapia fingerlings.
