Document Summary
Food sources of fat: you should still pick healthy fats, if you are a super athlete, vegetable oil, nuts seeds, and avocado (mufa, pufa) What food sources of protein are best: low fat, low sodium sources, fish and legumes as often as possible. Difference between whey, soy and carbohydrate supplement: looked at lean muscle mass before and after training. Study findings: 9 months of resistance training along with supplementation, whey supplements increased lean body mass (muscle mass) more than soy and carbohydrate supplements, no different in body weight between groups. Moral of the story is: there may be a tiny benefit but, if you want bigger muscles you have to do the work. What about iron: because iron involved in energy production athletes tend to need more. Females have poorer iron status than males: why, iron deficiency anemia occurs in ~10% of female athletes, blood loss due to menstruation coupled with poor diet, supplementation may be needed.
