Aspirin is best known for its ability to ease pain but it's also common for doctors to prescribe it as blood thinner for patients at high risk of a heart attack.

But its ability to block deadly blood clots may be hindered by dietary fat.

Two different kinds of fatty acids which come from animals and vegetable are released into the blood stream during the break down of fat cells. According to the American Heart Association, both types of fatty acids interfered with aspirin's ability to reduce the risk of clots.

But, for now, experts say the results are preliminary and more research is needed.
