A comparison of the death rates for cardiovascular diseases in areas that have hard drinking water with rates in areas having soft drinking water has revealed significantly lower rates in those areas with higher water calcium contents.

A sociological technique previously used in a nutrition study in Mexico was adopted and used with success in a Peruvian village.

Significantly lower blood calcium levels and significantly higher blood phosphorus levels are seen in neonates fed on artificial mixtures of cows' milk than are seen in breast‐fed infants.

Alcohol in excess may act as a generalized bone marrow suppressant. The suppression may be due to an effect on folate metabolism.

The neuropathy induced by isoniazid therapy is generally believed to be due to vitamin B6 deficiency. However, it was difficult to demonstrate much increase in vitamin B6 excretion even in patients on a high dosage of the drug or in those who are slow to inactivate isoniazid.

Mammalian production of nitrogen gas has been postulated, but experimental results are open to alternative explanations.

Intensive rearing of steers using rations that accelerate the rate of weight gain had no effect on the protein, iron, thiamine, riboflavin, or niacin concentration of muscle meats or on these nutrients plus vitamin B12 folic acid, and vitamin A in the liver. The fat content of the muscles of the intensively reared animals was increased over that of steers raised on the range.

The concentration of glucogenic metabolites, including oxaloacetate, in the liver of ketotic cows was found to be depressed; this is consistent with the hypothesis that an increased rate of gluconeogenesis, resulting in a decreased concentration of oxaloacetate, is an important cause of ketogenesis and thus of ketosis.

The previously held theory that vitamin E prevents peroxidation of polyunsaturated fats in vivo has been questioned by one group of investigators. The low peroxide level of tissue lipids from rats and chicks given supplemental vitamin E is attributed to an inhibition of absorption of oxidized fatty acids from the intestinal tract.
