Twelve new studies published in the December issue of the American Journal Of Clinical Nutrition, say drinking 3 to 5 cups a day of green or black tea can boost weight loss, bone health, problem solving skills, concentration and your mood. The health properties of tea are indisputable. L-theanine helps produce the feel good neurotransmitters dopamine and serotonin; compounds in green and black tea increase energy expenditure and fat oxidation. You’ll burn about 100 more calories than normal each day by drinking tea. These compounds also increase the production of bone building cells and the antioxidants slow down bone loss in postmenopausal women. After eating that oh so good, BUT GREASY, burger and fries drink some black tea; it counteracts the effect of fatty foods on your blood pressure and arterial blood flow.
