State the important distinction between the terms 'serving size'and 'portion'. why do you think that portion sizes of many foodshave generally gone up for many people? What might be at least onereason (that might even sound fairly logical) that foods withhigher energy densities, and sometimes correspondingly lowernutrient densities, are eaten with greater frequency in manypeople's diets? .
. If the curve for sufficiency of intake of a given nutrientwere narrower (tighter) and the distance between the UL and boththe RDA and EAR thus less, how would this impact an individual'sapproach to attaining an adequate, but not excess, amount of suchnutrient?
