High-carb, low-carb diets linked to similar increase in mortality risk
A meta-analysis that included more than 400,000 participants found that mortality risk was elevated for people who followed high-carbohydrate diets and those who followed low-carb diets, according to a report in The Lancet Public Health. Diets that provide 50% to 55% of total energy from carbohydrates were associated with lower mortality risk, with substitution of plant-based proteins for carbs further reducing mortality risk.

Eating too little food can backfire for dieters
Eating too little food can send the body into famine mode, causing metabolism to drop, reducing the number of calories burned, and undercutting weight-loss efforts, said registered dietitian Libby Gordon. RD Kristin Koskinen says eating too few calories also may reduce non-exercise activity thermogenesis, which is the energy expended by the body doing regular activities, such as cleaning, cooking and fidgeting.

RDN: Choose a balanced diet for good health
Registered dietitian nutritionist Cathy Deimeke says research does not support either the paleo or keto diet, and any diet that forces people to almost give up an entire food group is not a good choice. Deimeke says to have good health people need a balanced diet and she recommends the Mediterranean diet.

Report: Some baby foods contain "worrisome" amounts of heavy metals
Report: Some baby foods contain "worrisome" amounts of heavy metals
Sixty-eight percent of 50 packaged baby food products contained "worrisome" levels of one or more heavy metals such as inorganic arsenic, cadmium, lead and mercury, and 30% may be a "potential health risk" if consumed daily, while all products had at least one heavy metal, according to a Consumer Reports study. The report also showed higher levels of at least one heavy metal, especially inorganic arsenic, in products with sweet potatoes and rice, while organic food products had similar odds of containing heavy metals compared with nonorganic products.

Weight gain after smoking cessation tied to diabetes risk
Individuals who gained weight by up to 11 pounds were at an almost 15% increased risk of developing type 2 diabetes in the first six years after quitting smoking, with the risk declining after five to seven years, compared with those who continued smoking, according to a study in The New England Journal of Medicine. Researchers evaluated data on 333,530 individuals and also found that quitting smoking led to a significantly reduced risk of dying from stroke, heart attack and other cardiovascular disease and from any cause, which they said outweighs the risk of diabetes.

Study looks at youth camp-related acute gastroenteritis outbreaks
Researchers found that more than 50% of US states had acute gastroenteritis outbreaks among children attending youth camps between 2009 and 2016, with 53% of outbreaks due to person-to-person transmission. The findings in the Journal of the Pediatric Infectious Diseases Society also showed that norovirus, salmonella and Shiga toxin-producing E. coli were the most prevalent suspected or confirmed etiologies.

Sedentary behavior interruption tied to improved glucose metabolism in children
Researchers found that children with overweight or obesity who engaged in brief periods of moderate-intensity exercise had lower insulin secretion and insulin levels during the three-hour oral glucose tolerance test and lower C-peptide levels than when they had uninterrupted sitting for three hours. The findings in Diabetes Care, based on 35 children aged 7 to 11, revealed that interrupting sedentary behavior was not associated with a substantial increase in energy intake.

Your body needs to be supported with not only enough calories to feel safe, and support energy needs, but also the right proportions of nutrients (carbs, fats, proteins) and vitamins and minerals.
