Low-energy-density diets are associated with higher diet costs per 10 MJ. Are diets of higher nutritional quality also associated with higher costs per 10 MJ? ⋯ In this study of self-selected diets of French adults, lower energy density and higher nutritional quality were associated with higher energy-adjusted diet costs. Higher-quality diets cost more not only because they have a low energy density but also because they are nutrient rich.

Adipose tissue in overweight patients with end-stage renal disease (ESRD) is a source of proinflammatory mediators, which could contribute to protein-energy wasting (PEW), cardiovascular disease, and increased mortality. Overweight in ESRD patients, however, is reported to be associated with better survival. ⋯ PEW is common in overweight ESRD patients and is associated with high FBMI, low LBMI, and inflammation. PEW was a predictor of mortality in both obese and nonobese sarcopenia patients. BMI as such, however, was a poor predictor of mortality, but after adjustment for various confounders, including PEW, a high BMI and a high FBMI were associated with survival advantage.
