Are nuts healthy?

30g of mixed nuts on a scaleStudies suggest that consuming about 30g (a handful) of nuts per day may reduce the risk of developing heart disease by 30-50% and reduce the risk of death from heart disease by around 20%.

This is based on the high proportion of healthy monounsaturated and polyunsaturated fats in nuts, and the low proportion of saturated fats, and the results of studies comparing heart disease rates among people who eat nuts with those who do not.
