Randomized Controlled Trial
Effect of simultaneous supplementation of vitamin A and iron on diarrheal and respiratory tract infection in preschool children in Chengdu City, China.
The goal of this study was to investigate whether vitamin A combined with iron supplementation for preschool children resulted in improved changes in children's infectious morbidity. ⋯ The beneficial affects on infectious morbidity over 6 mo, highlight the potential of vitamin A plus an iron supplement for preschool-aged children.

Randomized Controlled Trial
The influence of consuming an egg or an egg-yolk buttermilk drink for 12 wk on serum lipids, inflammation, and liver function markers in human volunteers.
Dietary cholesterol elevates serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) concentrations modestly. There are indications that the cholesterol-raising effect depends on the food matrix, that is, sphingolipids and lactic acid bacteria are suggested to influence cholesterol metabolism. Traditional buttermilk is rich in both sphingolipids and lactic acid bacteria. Therefore, the aim of this study was to evaluate whether effects on cholesterol metabolism depend on food matrix (e.g., cholesterol provided as egg [yolk] or incorporated into traditionally prepared buttermilk drink). ⋯ Daily egg consumption for 12 wk increases serum TC and LDL-C concentrations in women but not markers for inflammation, endothelial activity, and liver function. Interestingly, the rise in serum LDL-C concentrations is less pronounced when egg yolk is incorporated into a buttermilk drink, indeed suggesting that fractions in the buttermilk might influence dietary cholesterol absorption.

Higher vitamin B status has been linked to a lower risk for cancer, but the underlying mechanism remains elusive. The aim of the present study was to examine the association of pyridoxal, folate, and homocysteine (Hcy) with urinary 8-hydroxydeoxyguanosine (8-OHdG), a marker of oxidative DNA damage. ⋯ The results suggest that vitamin B6, but not folate and homocysteine, plays a role against oxidative DNA damage in Japanese men.

The aim of this study was to explore whether type of eating behavior is related to diet and overweight in women after childbirth. ⋯ We demonstrated that certain types of eating behavior related to both energy-dense diet and weight and central adiposity. We propose that measuring eating behavior by the simple questionnaire could be a helpful tool in dietary counseling that aids in identifying women who are likely at risk for unhealthy dietary patterns and for developing overweight.
