Could walnuts prevent heart attack?

Two handfuls of walnuts a day could help stave off heart disease, a new study has revealed.
The tree nuts lower total cholesterol levels in the body, thus reducing the chances of a person suffering a heart attack. The snack contains important nutrients such as unsaturated fats, protein, vitamins and minerals, researchers said.
Dr Michael Falk, one of the authors from the Life Sciences Research Organisation, said: 'Our study results further support the growing body of research that tree nuts, such as walnuts, can reduce the risk of cardiovascular diseases.

'Tree nuts contain important nutrients. Walnuts are the only nut that provide a significant amount - 2.5g per one ounce serving - of alpha-linolenic (ALA), the plant-based form of omega-3.'

Dr Falk and his team conducted a systematic review and meta-analysis of 61 controlled trials to arrive at their conclusions. They found walnuts are effective in lowering total cholesterol, LDL, so-called 'bad' cholesterol, and ApoB, the primary protein found in LDL cholesterol. These are key factors that are used to evaluate a person's risk of cardiovascular disease.
