Randomized Controlled Trial
No effects of low and high consumption of dairy products and calcium supplements on body composition and serum lipids in Puerto Rican obese adults.
Epidemiologic studies have shown that a high calcium intake is related to lower body weight, fat, and serum lipids in obese individuals. However, clinical studies have shown inconclusive results. The present study was conducted to determine if dairy or calcium supplementation alters body composition or serum lipids in Puerto Rican obese adults without dietary energy restriction or exercise. ⋯ A high dairy or calcium diet alone did not alter body composition or serum lipids profile in a sample of Puerto Rican obese adults.

Vitamin C provision improves mood in acutely hospitalized patients.
Hypovitaminosis C and D are highly prevalent in acutely hospitalized patients, but the clinical significance of these biochemical abnormalities is not known. Because deficiencies of vitamin C and D have been linked to psychologic abnormalities, vitamin C or D provision could improve the mood state of acutely hospitalized patients. ⋯ Treatment of hypovitaminosis C improves the mood state of acutely hospitalized patients.
