Consuming a slice of watermelon a day can help protect from heart disease by halting the formation of harmful cholesterol and also be
a help in weight control.
Scientists 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, Daily Mail reported.
LDL is a form of cholesterol that leads to clogged arteries and heart disease.
They believe the secret to watermelon's health-boosting properties lies in citrulline, a chemical found in the juice.
Although the latest investigation showed no significant effects on blood pressure, it did reveal watermelons had a powerful impact on other heart risk factors.
In Britain around 270,000 people a year suffer heart attack and nearly one in three die before they could reach hospital.
