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.
The researchers from Purdue
also observed that eating watermelon regularly helped to control weight gain
and resulted in fewer fatty deposits inside blood vessels.
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.
around 270,000 people a year suffer heart attack and nearly one in three die
before they could reach hospital.
