Nutritional experts recommend that adults consume at least half of all grains as whole grains – which includes the bran, germ, and endosperm portions of the grain kernel. Researchers from the University of Copenhagen (Denmark) enrolled 79 overweight/obese postmenopausal women in a 12 week long study. Each subject was assigned to consume and energy restricted diet consisting of either refined or whole-grain wheat products. At the end of the study term, both diets resulted in weight loss –the greater loss was observed in the whole-grain group, with subjects dropping an average of 3.6 kg, as compared to 2.7 kg on the refined wheat diet. The whole-grain diet group experienced an average 3% reduction of body fat, where as the refined wheat diet group experienced 2.1% reduction. Total and LDL (low-density lipoprotein, "bad") cholesterol increased by about 5% in the refined wheat diet group, whereas no such changes were observed in the whole-grain group. Taken collectively, the study authors submit that the physiological changes experience with whole grain diets "suggest a cardioprotective role for whole grain.”

242. Work Out to Ward Off Anxiety
Anxiety often remains unrecognized or untreated among patients with a chronic illness. Researchers from the University of Georgia (Georgia, USA) analyzed the results of 40 randomized clinical trials involving nearly 3,000 patients affected by heart disease, multiple sclerosis, cancer and chronic pain from arthritis. On average, the patients who exercised regularly reported a 20% reduction in anxiety symptoms, as compared to those who did not exercise...
