Maternal diet could affect kids' brain reward circuitry
Researchers in France found that rats who ate junk food during pregnancy had heavier pups that strongly preferred fat straight after weaning. However, a balanced diet in childhood seemed to reduce the pups' desire for fat. The pups also showed altered brain reward circuitry into adulthood. The findings could have implications for childhood nutrition and obesity in Western countries. (2017-09-25)

Energy dense foods may increase cancer risk regardless of obesity status
While there is a proven link between obesity and certain types of cancer, less is known about how the ratio of energy to food weight, otherwise known as dietary energy density (DED), contributes to cancer risk. To find out, researchers looked at DED in the diets of post-menopausal women and discovered that consuming high DED foods was tied to a 10 percent increase in obesity-related cancer among normal weight women. (2017-08-17)

Recently discovered brain chemical 'NPGL' controls appetite and body fat composition
NPGL, a recently discovered protein involved in brain signalling, has been found to increase fat storage by the body -- even when on a low-calorie diet. In addition, NPGL was shown to increase appetite in response to high caloric food intake, suggesting that perhaps we shouldn't feel so guilty about gorging on junk food from time to time. (2017-08-17)
