Study ties carnitine in meat to heart disease risk
Eating red meat encourages the growth of gut bacteria that break down a compound called carnitine, which raises the risk of atherosclerosis by increasing levels of trimethylamine-N-oxide, or TMAO, Cleveland Clinic researchers reported in the journal Nature Medicine. The study found that increasing carnitine levels in people who had high levels of TMAO raised their risk of stroke, heart attack and other cardiovascular events. CBS News (4/8)

Dietary Health

"Overnight diet" combines eating plan and sleep, doctor says
Combining six days of a high-protein diet and one day of a liquid diet with getting a full night's sleep can lead to weight loss of 2 pounds overnight and up to 9 pounds in a week, according to Dr. Caroline Apovian, author of "The Overnight Diet." However, nutrition expert Keith Ayoob of the Albert Einstein College of Medicine says the overnight weight loss is mostly water, not fat, and that really losing 2 pounds requires burning thousands of calories.

RD: Balance calories, nutrition when recovering from injury
A healthy diet can help injuries heal, and athletes who are concerned about gaining weight need to balance nutrition and calories if they are temporarily sidelined, registered dietitian Linda Copp writes. She recommends eating foods from all food groups because they work together, and having frequent small meals or snacks to boost metabolism. San Diego Union-Tribune (4/8)

Science & Research

Eating more often tied to lower risk of being overweight in children
Children and teens, particularly boys, who ate more than three times a day weighed less than those who had three or fewer meals, according to a Greek study in the journal Pediatrics. Higher-frequency eating was also tied to a 22% decline in the odds of being overweight or obese, researchers said. HealthDay News (4/8), DailyRx.com (4/7)

Study links strict lunch standards, lower obesity risk in students
A study in JAMA Pediatrics showed that students who received free or subsidized meals through the U.S. Agriculture Department's National School Lunch Program were more obese than those who did not, but the difference was smaller in states with stricter meal standards. Researchers also found that students whose schools had strict lunch measures and healthier meals did not tend to compensate with less-healthy items from vending machines and other establishments.

Calcium from nondairy products cuts kidney stone risk
Regular intake of more than 450 milligrams of calcium from nondairy foods lowered the odds of developing kidney stones by 50% compared with eating 250 milligrams of calcium from nondairy sources, U.S. researchers found. They looked at the Health Professionals Follow-up Study and the Nurses' Health Studies, and noted that those who consumed the most calcium had a 77% reduced kidney stone risk compared with those who had the least intake. The findings appear in the Journal of Urology. MedicalDaily.com (4/5), Reuters (4/5)

Electronic media can promote healthier behaviors among youths
Participation in electronic-media-based intervention programs led to improved health behaviors among children and teens, such as increased physical activity and more fruit and vegetable intake, according to a study in JAMA Pediatrics. One of the 19 studies showed that a computer-based intervention on safe sex was linked to higher rates of sexual abstinence for up to three months among teens. DailyRx.com (4/8)

Fitness

Aging baby boomers have a wide range of fitness capabilities
Some aging baby boomers are healthy enough to run marathons, while others can handle only low-intensity activities, experts say. Geriatrics nurse Mary Ann Wilson, who created the "Sit and Be Fit" program, says exercise is effective for even the most frail individuals and can promote improved posture, balance, cognitive function, breathing and reaction time.

Conn. school earns praise for healthy, appetizing meals
U.S. Secretary of Agriculture Tom Vilsack and Connecticut Gov. Dannel P. Malloy were joined by lawmakers, nutrition advocates and others last week for a visit to a Connecticut elementary school, where they ate with students and discussed the importance of school-meal programs. "The simple fact is that children who aren't getting enough to eat can't be learning," said Malloy, who is currently urging more schools to serve breakfast, besides lunch. Patch.com/Avon, Conn. (4/6)
