Men and women who ingest at least 10g of nuts or peanuts daily have a lower chance of dying from several major causes of death than those people who do not consume them, a study found. But eating peanut butter does not yield the same benefit as eating peanuts in its truest form, according to a published study in the International Journal of Epidemiology.
Netherlands researchers said peanuts and tree nuts both comprise various antioxidants, fiber, vitamins and compounds like mono-unsaturated and poly-unsaturated fatty acids that probably contribute to lower death rates.
They say peanut butter contains trans fatty acids and salt that inhibit the beneficial effects of peanuts.
Respiratory disease and diabetes were found to have the strongest reduction of mortality followed by cancer and cardiovascular diseases.
The research found in the Netherlands Cohort Study, has run since 1986 among 120,000 Dutch men and women ages from 55 to 69 years old.
The participants’ nut-ingestion regimen were assessed by the portion size and frequency of consumption.
Piet van den Brandt, professor of Epidemiology led the study at Maastricht University declared the findings as “remarkable”.
“A higher intake was not associated with further reduction in mortality risk,” he said. “This was also supported by a meta-analysis of previously published studies together with the Netherlands Cohort Study, in which cancer and respiratory mortality showed this same dose-response pattern.”
