Bone mineral mass in adult lacto-ovo-vegetarian and omnivorous males.

Past studies indicate postmenopausal women who eat meat may experience greater bone mineral loss than lacto-ovo-vegetarian women. The present study extends those findings by comparing bone mineral in adult lacto-ovo-vegetarian and omnivorous males. Bone mineral mass was determined by direct photon absorptiometry in 320 lacto-ovo-vegetarian and 320 omnivorous males 20 to 79 yr old.

Dietary obesity in rats: influence on carbohydrate metabolism.

When male rats were fed a high diet from 3 to 20 weeks of age, they weighed 633 g which was 30% more than the animals fed a high glucose diet. Blood samples after a 16 to 18 hour fast, from the rats fed the high fat and high glucose diets contained, respectively: 130 +/- 11, 110 +/- 8 mg glucose/100 ml; 27 +/- 5, 24 +/- 3 microunits immunoreactive insulin (IRI)/ml; 791 +/- 58, 1104 +/- 179 meq nonesterified fatty acids (NEFA)/L. A tolerance test, by stomach tube, with 125 mg of glucose/100g body weight indicated that the rats fed the high fat diet had significantly higher mean plasma glucose concentrations, lower IRI responses and a lower leve of NEFA than rats fed a high glucose diet.

Sodium and potassium intakes and excretions of normal men consuming sodium chloride or a 1:1 mixture of sodium and potassium chlorides.

Two groups of 10 healthy young men were matched on the basis of their free-choice consumptions of regular table salt. For 28 days they were then fed carefully controlled low-sodium foods. One group was permitted free-choice seasoning of these foods with regular table salt, the other with a 1:1 mixture of sodium and potassium chlorides.
