Too Many Colas Can Lower Bone Density in Women
Drinking too many colas may weaken your bones, according to results from a Tufts University study. More than half of women in their late-thirties and older who drank more than 350 ml a day of regular, diet and caffeine-free cola were found to have bone densities five percent lower than women who drank 350 ml or less per week.
According to the researcher in charge of the study, phosphoric acid is believed to be the cause, as no decrease in bone density was found as a result of drinking carbonated beverages other than cola that did not contain phosphoric acid.
Phosphoric acid is believed to combine with calcium in the intestines and weaken bones by preventing calcium absorption. It is also believed to have a detrimental effect on parathyroid hormones that regulate bone density.
No connection between colas and reduced bone density was confirmed in men. (From Shape, U.S.A.)
Vegetable Juice Increases Immunity
Drinking vegetable juice may be a good way to increase your immunity. A nutritional physiology study conducted at the German Federated Nutritional Research Center found that drinking vegetable juices such as tomato juice and carrot juice every day can increase the function of immune cells up to a maximum of 25 percent.
Drinking the juice together with a meal was found to be the most effective. “A certain amount of fat is necessary for carotenoids to be effectively absorbed,” said the researcher in charge of the study. (From Men’s Health, U.S.A.)
Magnesium Reduces Risk of Heart Disease
Eating magnesium-rich foods such as peanut butter and whole grain bread can reduce the risk of heart disease. That was the finding of a research team at the University of Virginia Health System.
The results of a 15-year study involving 7,000 males found that those with insufficient magnesium were nearly twice at risk of developing coronary arterial heart disease. “The risk greatly decreases as magnesium intake increases,” said the researcher in charge. The risk of atherosclerosis and hypertension are thought to increase if the intake of magnesium is too low. The goal should be about 420 milligrams per day.
Simply eating a slice of whole grain bread with peanut butter will provide approximately one-third of that requirement. (From Men’s Health, U.S.A.)
