Why social supermarkets are gaining attention in the fight against food insecurity

This scoping review found that social supermarkets can offer a more dignified, choice-based way to access lower-cost food while also helping divert some surplus food from waste.

Researchers debunk the existence of the childhood "adiposity rebound" phenomenon

In new research to be presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) and published in The Journal of Nutrition, a 42-year old theory as to why children's body mass index (BMI) decreases post-infancy before then rising continuously from age six years –'the adiposity rebound' is refuted using new analyses – rather than decreasing body fat, the real reason is proposed as increasing muscle mass.

BMI increases in early childhood may reflect muscle growth, not fat

A new study published in The Journal of Nutrition, a peer-reviewed journal of the American Society for Nutrition, offers new insights into a decades-old puzzle in childhood obesity. The study found that while body mass index (BMI) starts to rise in early childhood during a stage known as adiposity rebound, when BMI increases after an initial decline, the waist-to-height ratio, a measure that better reflects body fat, continues to drop. This suggests that the BMI increase at this age mainly reflects growth in lean tissues such as muscle and bone, rather than extra body fat.
