Recently, Miriah participated in a study that was designed to determine how much iron is necessary to prevent iron deficiency. Within a few weeks of consuming an iron-free diet, Miriah's red blood cells began to show signs that they lacked iron, and she began to complain about feeling tired. At that point, the researcher added some iron to Miriah's food, so her daily intake of the mineral was 1 mg. After 1 week, the researchers checked the iron content of Miriah's blood, and although it was higher than the earlier value, she still complained about feeling tired. In the weeks that followed, the scientists continued to increase Miriah's iron intake by 1 mg/week and check her for signs and symptoms of iron deficiency. After a week of taking 6 mg of iron/day, she reported feeling like "her
old self" and having plenty of energy. Based on this information, the researchers concluded that Miriah's A. RDA for iron was 6 mg. B. body required 6 mg iron/day. C. UL for iron was 6 mg, plus 3 mg as a margin of safety. D. AMDR for iron was 6 mg/day.
Nutrients can be used to compensate for some gaps in our DNA. For example:
A) ?Individuals with a change in the base sequence for the phenylalanine hydroxylase gene can correct the sequence of bases by eating a lot of phenylalanine. B) ?Obese individuals can lose body weight by eating fewer calories than they expend. C) ?Omega-3 fatty acids can upregulate genes encoding for fat oxidation. D) ?Individuals with a polymorphism that decreases activity of a folate-metabolizing enzyme, methylene tetrahydrofolate reductase, may have more elevated plasma homocysteine than those with a normal enzyme while more folate intake can normalize plasma homocysteine for those with this polymorphism.
