the nutritions requirements of 97-98% of individuals
what is the adequate intake

why is the AI true
the infants use this method
tolerable upper intake
the highest average daily intake
potential risk of adverse effects may increase
why does these designed made?
to ensure the micronutrients consumed sufficiently
deficient in essential micronutrients ?
diet low in carbohydrates or fats
what is the cause of diet low in protein
lean of the muscle mass
