Both low (33 mg/kg) and very high (13,200 mg/kg) levels of vitamin C decreased body weight, glutathione reductase, and unsaturation of fatty acids in membrane lipids. The results show that a diet supplying an amount of vitamin C 40 times higher than the minimum daily requirement to ...
One gram of a certain health food contains 7 percent of the minimum daily requirement of vitamin E and 3 percent of the minimum daily requirement of vitamin A. If vitamins E and A are to be obtained from no other source, approximately how many grams of t
In this primary investigation on breast milk quality the fat content was found to be marginal; the majority of lactating mothers (92·0 %) were not providing the minimum daily requirement (1·05 μmol/l) of retinol to their babies. 展开 ...

[8]For children, pregnant women, and lactating women, the RDA is 300 to 900, 770, and 1300 micrograms/day, respectively. The minimum requirement to prevent symptomatic VAD in children 1 to 5 years of age is about 200 micrograms/day. Serum retinol levels are a good marker of vitamin A ...
