A sharp increase in the prevalence of obesity and a decline in iron deficiency in children was observed between the two consecutive Nutrition and Health Surveys in Taiwan. The aim of this study was to evaluate the distribution of hepcidin in relation to nutritional status in children. ⋯ Our results raise the possibility that IL-10 may play a role in iron homeostasis. Decreased circulating IL-10 concentration may temporary protect young overweight/obese girls against the development of iron deficiency. However, long-term decrease in hepcidin concentration may increase the risk for iron overload in overweight/obese children.

Resistance training is a potent stimulus to increase skeletal muscle mass. The muscle protein accretion process depends on a robust synergistic action between protein intake and overload. The intake of protein after resistance training increases plasma amino acids, which results in the activation of signaling molecules leading to increased muscle protein synthesis (MPS) and muscle hypertrophy. ⋯ The aim of this review is to present recent findings reported in the literature and to discuss the practical application of these results. In that light, new speculations and questions will arise that may direct future investigations. The information and recommendations generated in this review should be of benefit to clinical dietitians as well as those engaged in sports.

Meta Analysis
Tea consumption and lung cancer risk: a meta-analysis of case-control and cohort studies.
Recent epidemiologic studies, especially cohort and case-control studies, have yielded inconsistent findings regarding the association between tea consumption and risk for lung cancer. The aim of this study was to assess a potential relationship between tea consumption and the incidence of lung cancer worldwide. ⋯ Tea consumption may offer some protection against lung cancer.

Meta Analysis
Association of vitamin A and β-carotene with risk for age-related cataract: a meta-analysis.
Whether vitamin A and β-carotene as nutrients are protective factors against cataracts remains unclear. Thus, the aim of this study was to summarize the evidence from epidemiologic studies of vitamin A and β-carotene with the risk for cataract. ⋯ Greater vitamin A and β-carotene intakes might be inversely associated with risk for cataract.

Randomized Controlled Trial
Randomized clinical trial: effect of Lactobacillus plantarum 299 v on symptoms of irritable bowel syndrome.
Irritable bowel syndrome (IBS) is a common diagnosis in gastroenterology. Its etiology is unknown and therapeutic options limited. Trials suggest probiotics may be beneficial. The aim of this study was to assess the symptomatic efficacy of Lactobacillus plantarum 299 v (L. plantarum 299 v) for the relief of abdominal pain in patients with IBS fulfilling Rome II criteria. ⋯ An 8-wk treatment with L. plantarum 299 v did not provide symptomatic relief, particularly of abdominal pain and bloating, in patients fulfilling the Rome II criteria.
