Peanut and Peanut Butter may lower the risk of Type 2 Diabetes

They can play also a role in the prevention of obesity and CVD.

Scientists at the Harvard School of Public Health have been busy studying the association between nut consumption and the risk of Type 2 diabetes - and their findings are promising. The study results suggest that eating peanuts and peanut butter may help lower the risk of Type 2 diabetes in women.

Why?
Peanuts and peanut butter are high in unsaturated fat - the "good fats" - and are nutrition powerhouses containing fibre, folate, magnesium, zinc and vitamin E.

 

Study facts
Study participants: 83,818 women (34-59 years old) with no history of diabetes, CVD, or cancer followed up for 16 years

 

  • Eating nuts and/or peanut butter lowered the chances of developing Type 2 diabetes
  • Reduction in risk was greatest in those who had the highest nut consumption
  • Those who never/ almost never ate peanuts had no change in risk
  • Those who consumed peanuts (1oz/ 30g serving) less than once per week, had an 8 per cent lower risk
  • Those who consumed peanuts 1-4 times per week had a 16 per cent lower risk
  • Those consuming peanuts 5 or more times per week, had a 27 per cent lower risk
  • Those who consumed peanut butter five or more times per week (the equivalent of 5 tablespoons) had a 21 per cent lower risk compared to women who never or almost never ate peanut butter
  • Subjects who ate more peanuts and who were at higher risk due to their other factors (e.g. overweight, smoking) had a lower risk than those who ate fewer or no nuts.

 

Peanuts and peanut butter also make delicious and nutritious additions to a variety of recipes: sauce, soup, dressing...

So spread the news! Regular or daily consumption of peanuts and peanut butter can play a beneficial role in our diet and contribute to reducing risk of CVD, obesity and Type 2 diabetes.
