Randomized Controlled Trial Comparative Study
Once-weekly dose of 8400 IU vitamin D(3) compared with placebo: effects on neuromuscular function and tolerability in older adults with vitamin D insufficiency.
Vitamin D insufficiency, which is prevalent in older individuals, is associated with bone and muscle weakness and falls. ⋯ Weekly treatment with 8400 IU vitamin D(3) raised 25(OH)D concentrations in elderly, vitamin D-insufficient individuals. Treatment with 8400 IU vitamin D(3) did not reduce mediolateral sway significantly compared with treatment with placebo in this population, although in post hoc analysis, treatment with 8400 IU vitamin D(3) reduced sway in the subgroup of patients who had elevated sway at baseline. Weekly treatment with 8400 IU vitamin D(3) was well tolerated. This trial was registered at clinicaltrials.gov as NCT00242476.

Randomized Controlled Trial
An antiinflammatory dietary mix modulates inflammation and oxidative and metabolic stress in overweight men: a nutrigenomics approach.
Low-grade chronic inflammation in overweight subjects is thought to play an important role in disease development. ⋯ An intervention with selected dietary products affected inflammatory processes, oxidative stress, and metabolism in humans, as shown by large-scale profiling of genes, proteins, and metabolites in plasma, urine, and adipose tissue. This trial was registered at clinical trials.gov as NCT00655798.

The prominent clinical feature of cachexia has traditionally been understood to be weight loss; however, in recognition of the potential for divergent behavior of muscle and adipose tissue, cachexia was recently defined as loss of muscle with or without loss of fat mass. Detailed assessments are required to verify body composition in patients with cancer cachexia. ⋯ Wasting of skeletal muscle is a prominent feature of patients with lung cancer, despite normal or heavy body weights. The significance of muscle wasting in normal-weight, overweight, and obese patients as a nutritional risk factor, as a prognostic factor, and as a predictor of cancer treatment toxicity is discussed in this article.

The Nutrient Rich Foods (NRF) Index is a formal scoring system that ranks foods on the basis of their nutrient content. When used in conjunction with a food prices database, it can help identify foods that are both nutritious and affordable. ⋯ One important application of nutrient profile models is to help consumers identify foods that provide optimal nutrition at an affordable cost.
