AJCN June, 2011 -DETAILS

AJCN FEATURE his month: 1. Galactooligosaccharide supplementation reduces stress-induced gastrointestinal dysfunction and days of cold or flu in university students - Background: Acute psychological stress induced by academic exams is associated with dysregulated gastrointestinal and immune function. Objective: We examined whether supplementation with galactooligosaccharides reduced gastrointestinal dysfunction and the percentage of days with cold or flu in academically stressed undergraduate students. Results: Stress was positively related to diarrhea, indigestion, and reflux syndromes and with abdominal pain, average daily cold or flu SI score, and the percentage of days with cold or flu. Conclusions: Acute psychological stress was directly related to symptoms of gastrointestinal dysfunction and cold or flu. Galactooligosaccharide supplementation (2.5g/day) reduced these symptoms and the number of days with cold or flu. They are found in chicory, onions (and the rest of the "onion family", including leeks and garlic), legumes, wheat, asparagus, jicama, and other plant foods.

EVERYONE: 2. Main sources and types of beneficial polyphenols in food (in France):

3. Antioxidants safe during athletic training - It was recently reported that antioxidant supplementation decreases training efficiency and prevents cellular adaptations to chronic exercise. No such effects were found in a double-blind study using vitamins C and E daily.

4. Habitual coffee consumption has little effect on hypertension

5. Leucine helps maintain healthy intestines.

OBESITY: 6. Obesity alters brain size to desire more food - This study showed that the amygdala and hippocampus are enlarged in obesity. In consideration of the function of these structures, this finding may indicate that hedonic memories could be of major importance in the regulation of feeding.

7. Video game playing increases food consumption

8. Monosodium glutamate consumption is positively associated with obesity.

PARENTS: 9. The strongest and most consistent associations of a woman's weight gain during pregnancy (GWG) and in the rest of her life are in early and midpregnancy (0–28 wk). The findings remind us that how heavy a woman is when she conceives is a more important determinant of her obstetric risk than is GWG. Today, ≈60% of American women of childbearing age are overweight or obese (12), and practitioners find it difficult to counsel them about weight before or during pregnancy.2. Iron deficiency remains the most prevalent micronutrient deficiency wolrdwide.9. Low iron status in young women may be the result of riboflavin deficiency - Rather than requiring iron supplements, women with anemia might be helped by taking a multivitamin regularly, thus avoiding the hazard of getting too much iron.

10. Iron deficiency (ID) in US occurs in 18% of pregnant women, mostly in later trimesters in non-Caucasians. ID prevalence (±SE) in US pregnant women, which was defined as total body iron <0 mg/kg, was 18.0 ± 1.4%. Pregnant women in the first trimester had a higher mean total body iron than did pregnant women in the second or third trimesters. ID prevalence in pregnant women increased significantly with each trimester (6.9 ± 2.2%, 14.3 ± 2.1%, and 29.5 ± 2.7% in the first, second, and third trimesters, respectively).

11. C section delivery increases risk of adult obesity

STUDENTS: 12. One night of sleep deprivation slows metabolism contributing to weight gain.

13. Low iron status in young women may be the result of riboflavin deficiency - Rather than requiring iron supplements, women with anemia might be helped by taking a multivitamin regularly, thus avoiding the hazard of getting too much iron.

WORLD: 14. Iron deficiency remains the most prevalent micronutrient deficiency worldwide.
