Increasing evidence suggests that early nutrition has programming effects on adult health. Identifying mechanisms underlying nutritional programming would aid in the design of new disease prevention strategies. The intestinal microbiota could be a key player in this programming because it affects host metabolic homeostasis, postnatal gut colonization is sensitive to early nutrition, and initial microbial set-up is thought to shape microbiota composition for life. The aim of this study was to determine whether early manipulation of intestinal microbiota actually programs adult microbiota in rats. ⋯ As revealed by a targeted quantitative polymerase chain reaction approach, programming of adult intestinal microbiota seems to vary according to the nature of the preweaning microbiotal modulator. This suggests that intestinal microbiota may, only under specific circumstances, serve as a relay of neonatal nutrition and thus potentially contribute to nutritional programming of host physiology.

Effects of a single dose of a flavonoid-rich blueberry drink on memory in 8 to 10 y old children.
Recent evidence from animals and adult humans has demonstrated potential benefits to cognition from flavonoid supplementation. The aim of this study was to investigate whether these cognitive benefits extended to a sample of school-aged children. ⋯ Although findings are mixed, the improvements in delayed recall found in this pilot study suggest that, following acute flavonoid-rich blueberry interventions, school-aged children encode memory items more effectively.

Glucomannan (GM), a soluble fiber derived from the plant Amorphophallus konjac, is marketed as being helpful in reducing body weight. However, the data supporting this claim are scarce. The aim of this review was to systematically evaluate the effects of GM on body weight (BW) and body mass index (BMI) in otherwise healthy obese or overweight children and adults. ⋯ In otherwise healthy overweight or obese adults, there is some evidence that in the short term GM may help to reduce BW, but not BMI. Data in children are too limited to draw any conclusions.

Antiinflammatory effects of L-carnitine supplementation (1000 mg/d) in coronary artery disease patients.
Inflammation mediators have been recognized as risk factors for the pathogenesis of coronary artery disease (CAD). The purpose of this study was to investigate the effect of L-carnitine supplementation (LC, 1000 mg/d) on inflammation markers in patients with CAD. ⋯ We suggest that LC supplementation, due to its antioxidant effects, may have potential utility to reduce inflammation in CAD.
