Watermelon cuts heart attack risk, weight gain

A daily slice of watermelon can protect you from heart disease and weight gain by preventing the build-up of harmful cholesterol, according to a new study. Researchers from Purdue University in the US who carried out studies on mice fed a high-fat diet found the fruit halved the rate at which 'bad' low-density lipoprotein, or LDL, accumulated.

LDL is a form of cholesterol that leads to clogged arteries and heart disease. The study found that the fruit also helped to control weight gain and resulted in fewer fatty deposits inside blood vessels, the Daily Mail reported. Researchers believe the secret to watermelon's health-boosting properties lies in citrulline, a chemical found in the juice.
Previous studies have suggested citrulline has a role to play in heart disease prevention by lowering blood pressure.
