Go Nuts To Reduce Risk of Dying

nuts reduce risk of dying

Unless you have a nut or peanut allergy, new research findings suggest you may want to eat at least half a handful of nuts or peanuts every day. At least 10 grams of these foods, but not peanut butter, could reduce your risk of succumbing to several major causes of death.


You may be familiar with some of the reports about the health benefits of nuts. For example, nuts (pistachios) have been associated with better gastrointestinal health, walnuts and other tree nuts are helpful for people with diabetes, almonds can be beneficial in fighting colds and flu, and nuts may reduce the risk of dying from heart disease.

The new study was conducted within the Netherlands Cohort Study, which includes more than 120,000 adults aged 55 to 69 years and has been running since 1986. Investigators from Maastricht University had access to lifestyle and dietary data (portion size and frequency of consumption of tree nuts, peanuts, and peanut butter) as well as mortality follow-up information from Statistics Netherlands.

When nut consumption was compared with no nut consumption, the findings were as follows:

  • Reduction in risk of death was strongest for respiratory disease, neurodegenerative disease, and diabetes, followed by cancer and cardiovascular diseases
  • Benefits were equal in women and men
  • Tree nuts and peanuts demonstrated similar strong reductions in mortality, but peanut butter did not
  • Intake of more than 15 grams of nuts and/or peanuts daily was not associated with a greater reduction in risk of dying

What’s so special about nuts and peanuts? They contain healthful fats (monounsaturated, polyunsaturated), antioxidants, vitamins, fiber, and other substances that may be instrumental in reducing mortality.

According to the National Health and Nutrition Examination Survey 2009-2010, 38.2 percent of adults consumed nuts on a given day. Of that amount, about 80 percent of nuts eaten were nuts or seeds as single-item foods or nut butters.

In this study, peanut butter was not found to be associated with a reduction in mortality. The authors noted that peanut butter contains other ingredients, such as vegetable oils and salt, and in the past it also contained trans fats, all of which could negate the positive impact of the peanuts themselves.

Whether natural, organic peanut butter and nut butters without any added ingredients would provide the same health benefits as the nuts themselves was not explored in this study. However, it is a legitimate question that could be pursued.

For now, the bottom line appears to be that eating a small amount of nuts, 10 to 15 grams daily (one-third to one-half ounce, which provides less than 100 calories on average) could reduce the risk of dying from several major medical conditions.

Nuts prevent cancer? In the case of bowel/colorectal cancer, the surest way to prevent it is to have a colonoscopy, during which pre-cancerous "polyps" are removed (if you're quick). - @grputland
Peanut butter, or anything roasted, especially (by far) those foods with a lot fat, will contain high level of AGE's, Advanced Glycation End products. The figure for peanut butter, "raw" cashew nut (almost no such thing as a raw cashew nut available for the consumer, I believe, as cashew nuts are steamed in the shell), and roasted nuts of all kinds is quite high. It is hard to be specific because the figures I have access to are per serving, making it impossible to compare peanut butter to boiled chicken, cheese or fried bacon. I also feel that most dried nuts are outright rancid, e.g. walnuts. The only dried nut I trust not to be rancid is the almond. These factors, if anything, will promote cancer. Fresh nuts are another thing, but consumers are misled big time when they buy for example müsli with roasted nuts, believing "nuts" are healthy. It depends on how they are treated.
