Is glycemic index of food a feasible predictor of appetite, hunger, and satiety?

This review assesses the feasibility of using glycemic index (GI) as a predictor of appetite, hunger and satiety by surveying published human intervention studies. We also discuss the relationship between GI and two appetite/satiety control hormones, leptin and ghrelin. Ingestion of high-GI food increased hunger and lowered satiety in short-term human intervention studies.

Macronutrient, mineral and trace element composition of breast milk from Japanese women.

The aim of the study was to determine the concentrations of macronutrients and the mineral and trace element composition in maternal milk of Japanese women. We collected human milk samples from mothers living throughout Japan from December 1998 to September 1999, and defined as group A the 1197 samples among them that met the following conditions: breast milk of mothers who were under 40 years old, not in the habit of smoking and/or using vitamin supplements, and whose babies showed no symptoms of atopy and whose birth weights were 2.5 kg or more.

Fat-soluble and water-soluble vitamin contents of breast milk from Japanese women.

To determine the concentrations of fat-soluble and water-soluble vitamins in the maternal milk of Japanese women, we collected human milk samples from more than 4,000 mothers living throughout Japan between December 1998 and September 1999, and defined as group A the 691 samples among these that met the following conditions: breast milk of mothers who were under 40 y of age, who did not smoke habitually and/or use vitamin supplements, and whose babies showed no symptoms of atopy and had birth weights of 2.5 kg or more. We then analyzed the contents of vitamins individually.

Reactivity of secretory IgA antibodies in breast milk from 107 Japanese mothers to 20 environmental antigens.

The secretory IgA (sIgA) antibody response to 20 environmental antigens, including microorganisms, toxins, food, and inhaled allergens, was evaluated in the breast milk from 107 Japanese mothers 1-10 days after delivery. Specific sIgA antibody responses were detected in most milk samples against almost all of the antigens tested, although there was a wide variation in the specific sIgA antibody profiles of each individual's milk. With regard to twelve bacterial antigens, highly specific sIgA antibody responses were detected against Escherichia coli, Yersinia enterocolitica, and Pseudomonas aeruginosa.
