A high-protein diet does not promote healthful weight loss, according to a study published in Cell Reports. Researchers assigned obese postmenopausal women to a calorie-restricted diet with either a high-protein (1.2 g/kg) or normal-protein (0.8 g/kg) diet and monitored insulin sensitivity. Although both diets resulted in a reduction in body weight, the high-protein group did not improve its insulin sensitivity or reduce oxidative stress as observed with the normal-protein diet. Researchers caution that high-protein diets’ failure to improve the primary mechanism for type 2 diabetes raises concern.

Nutrition Tip of the Day
Chew Your Food! Your mother taught you to chew your food and keep your mouth closed while eating. Somehow with our busy schedules and eating on the go, we have forgotten our Ps and Qs. Food should ideally be chewed for 30 bites or until the food becomes liquid in your mouth. Chewing food activates the enzymes in your mouth (salivary amylase) to begin the breakdown of food into absorbed nutrients. This also sends a signal to your stomach and the rest of your digestive system to prepare itself for the vitamin and mineral overload that is heading its way.
