Researchers say that three cups of green or black tea a day can protect against heart attacks by as much as 11 percent. Antioxidants in the tea help reduce the build-up of plaque in the arteries:
"The review by researchers at the University of Western Australia says the benefits of tea are largely due to the flavonoid content, antioxidant ingredients that counteract cardiovascular disease.
"One cup of tea provides 150-200mg of flavonoids."
Scientists have also found that red onions help to prevent heart disease and stroke. The vegetables remove bad cholesterol while retaining the body’s good cholesterol at the same time:
"Scientists in Hong Kong fed crushed-up red onions to hamsters who had all been put on a high-cholesterol diet. They found that after eight weeks levels of bad cholesterol, or low density lipoprotein (LDL), had dropped by an average of 20 percent.
"But over the same time period there was no reduction in the hamsters' high cholesterol levels, also known as high density lipoprotein (HDL)."
A new study in the journal Experimental Physiology proves it: men sweat more than women. Sweating is the body's way of cooling off, so this gives men the ability to exercise longer and benefit more from the activity:
"Researchers measured the rate at which both men and women perspired while biking for an hour under controlled conditions. Men who were physically fit sweat more readily than anyone else, and men, in general, also appeared to benefit more from physical training than did women. This difference became more pronounced as the activity level increased.
"Physically fit people begin to sweat at a lower core body temperature. And since sweating is our body's way of cooling off (and keeping from overheating), this allowed men to perform longer, according to the researchers. Inactive women had the lowest sweat rate."
