Consumption of Nuts Reduces Risks of Early Mortality and Neurodegenerative Diseases? (BBC News / NHS Choices / International Journal of Epidemiology)


Researchers at Maastricht University have discovered there is a 23% lower chance of death over a 10-year study period in people eating 10g (0.3oz) or more of nuts or peanuts per day.

Over 120,000 Dutch middle-aged to elderly men and women (55-to-69-year olds) provided dietary and lifestyle information back in 1986, and their mortality rates were subsequently examined. Risks of premature mortality due to cancer, diabetes, respiratory and neurodegenerative diseases were lower for the consumers of nuts; with an average 23% lower risk of 10-year mortality across all diseases. Specifically, there were decreased risks of:

  • 45% for mortality due to neurodegenerative diseases.
  • 39% for mortality due to respiratory diseases.
  • 30% for mortality due to diabetes.

There appears to be no benefit from consuming peanut butter, possibly because such processed foods contain salt and trans fats.
