Food guides for the vegetarian.

Special consideration must be given to providing key risk nutrients in planning food guides for vegetarians especially if the diet chosen excludes all animal products, such as dairy foods and eggs. The practical use of food guides for education is also important. Several food guides for adult vegans, including pregnant vegan women, were analyzed by computer for nutritional adequacy using 7-d menus and comparisons were made with the RDA for energy, protein, iron, calcium, and riboflavin. Several patterns were identified that supply the RDA for protein, iron, calcium, and riboflavin and have educational merit. None of the patterns provide sufficient energy to meet the RDA.

Mammary gland function and development: effect of zinc deficiency in rat.

The effect of dietary zinc deficiency during late pregnancy and lactation on the rat mammary gland was investigated by feeding female rats either a zinc-deficient diet (0.4 ppm Zn) or a zinc-sufficient diet (100 ppm Zn) ad libitum or restricted in amount. Zinc deficiency from day 0 of lactation specifically reduced the total RNA content of lactating mammary glands on day 14, but had no effect beyond that of food restriction on their total DNA content, Both RNA and DNA content of the mammary gland were decreased by reduced food intake. Zinc deficiency from day 14 of pregnancy to day 2 of lactation severely impaired parturition and prevented the normal rise in mammary gland RNA seen during lactogenesis in control animals. A shorter deficiency period, from day 18 of gestation, had no effect on mammary gland nucleic acids other than that due to inanition.
