Eating an Early Dinner Can Help You Burn Fat, Lower Your Blood Sugar

Healthline  online


“Although the study was conducted with young adult, healthy weight volunteers, it provides us with some helpful information to guide eating habits,” said Lisa K. Diewald, MS, RD, LDN, program manager, MacDonald Center for Obesity Prevention and Education at Villanova University M. Louise Fitzpatrick College of Nursing. Diewald adds that the findings are significant for disease prevention. “This study provides a reminder that cultivating eating habits addressing not only traditional factors such as meal content and size, but also meal timing, may influence the risk of chronic diseases such as diabetes and heart disease down the road.” According to Diewald, dinner is, by far, the largest meal of the day for most adults in terms of calories. She explained that busy people typically rush through breakfast and lunch, which often means eating later, and more, than they should. “[This] can leave you yearning for a large meal late at night, which as this study highlights can result in some difficulties with glucose or fat metabolism, even in young individuals with a healthy weight.”

Keep Your Bones Strong

Womans Day  print


The Dietitian Says... What you eat really matters Some research shows that the Mediterranean diet is best for healhty bones. It inclues plenty of fruits, vegetables, whole grains, and legumes and some dairy, lean animal protein, olive oil, and nuts. Nutrients in this eating plan (like vitamin D, omega-3 fatty acids, magnesium, vitamin A and, yes, calcium) contribute to bone health. It's best to get calcium from foods like dairy, leafy greens, almonds, white beans, and acorn squash, but if you can't, supplements are an option. Fewer foods supply vitamin D, so consider a supplement if you're not getting enough (400 to 800 IU daily, depending on your age). You'll want to avoid excess sodium, caffeine, alcohol, and phosphoric acid (found in soda) as well as too much or too little protein, all of which can contribute to bone loss. LISA K. DIEWALD, M.S., R.D., L.D.M, program manager of the MacDonald Center for Obesity Prevention and Education at Villanova University M. Louise Fitzpatrick College of Nursing.

How Many Eggs Are Healthy To Eat?

Huffington Post  online


Eggs are one of the most versatile foods out there ― you can cook them in endless ways, they keep you full for hours and they’re a nutritional powerhouse loaded with protein and other nutrients that protect eye, muscle and bone health.

Calorie Counts on Menus Are Working

Healthline  online


Earlier this year, the Food and Drug Administration (FDA) enacted a law requiring restaurants and grocery stores with 20 or more locations to display calorie counts on standard menu items. As part of the Affordable Care Act of 2010, the new requirements were designed to help tackle America’s obesity crisis — an epidemic that has skyrocketed in the past 50 years, with nearly 70 percent of U.S. adults being obese. And so far, the rules seem to be working.
