Study links eating just half a serving a day of nuts, such as walnuts, to a decreased risk of cardiovascular disease (CVD)

A recent study1 supported by the California Walnut Commission (CWC) and published in the Journal of the American Heart Association has linked eating just half a serving a day of nuts, such as walnuts, with a decreased risk of cardiovascular disease (CVD).

For the research, Harvard TH Chan School of Public Health asked over 190,000 men and women in the US to record their nut consumption over a four-year period. The participants’ risk for CVD was then assessed over the subsequent four years.

Compared with those who consumed no nuts, the study participants who ate just half a serving a day of nuts, such as walnuts, had a lower risk of CVD, coronary heart disease and stroke. (A serving of walnuts is approximately 30g).

According to the NHS, CVD is one of the main causes of death and disability in the UK, but can often largely be prevented by leading a healthy lifestyle.2
