Adding another reason for doctors to avoid the overuse of antibiotics, new research shows that a reduction in the variety of microbes in the gut interferes with the immune system's ability to fight off disease.
The research team examined the US Department of Agriculture's Smart Snacks in School regulation. The federal mandate was intended to replace unhealthy school snacks and beverages with more wholesome options, including fruits, vegetables, and packaged treats low in fat, sugar, and sodium.
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.
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.
A female fruit fly must balance her energy usage between making eggs now and storing nutrients for later. This balance affects the pheromones that she produces and impacts whether male fruit flies find her attractive, report Tatyana Fedina of the University of Michigan and colleagues, Aug. 17, 2017 in PLOS Genetics.
Farmers can grow big, juicy tomatoes thanks to a mutation in the Cell Size Regulator gene that occurred during the tomato domestication process. Esther van der Knaap of the University of Georgia, Athens and colleagues describe this gene variant in a study published in open-access journal PLOS Genetics on Aug. 17, 2017.
Children with lower diversity of microbial species in their intestines are more susceptible to severe infection with the Entamoeba histolytica parasite, according to a new study published in PLOS Pathogens.
Double-blind test bolsters observational data that walnuts promote feelings of fullness. Results provide a quantitative measure for testing other compounds' ability to control appetite, including potential medications for the treatment of obesity.
A study by researchers at King's College London has found that children who skip breakfast regularly may not be consuming the daily amounts of key nutrients for growth and development that are recommended by the UK government.
A new study conducted at the Weizmann Institute of Science, published in the Proceedings of the National Academy of Sciences, USA, has now opened the way to numerous potential uses of betalains, the highly nutritious red-violet and yellow pigments known for their antioxidant properties and commonly used as food dyes.
