Eat nuts or peanuts and live longer
If you eat nuts or peanuts regularly your risk of dying is lower than if you don't. According to a study published by epidemiologists at Harvard Medical School in the New England Journal of Medicine, a diet that is high in nuts and peanuts extends your life expectancy by offering protection against almost all kinds of fatal disease.
The protective effect of nuts had already been shown in similar epidemiological studies, but this one produced even more intriguing results. Nuts and peanuts reduced not only the chance of dying from cardiovascular problems, but also the chance of dying from cancer, diabetes, infectious diseases, lung and kidney diseases and 'non-classified' diseases.
It was also noticeable that consuming nuts and peanuts protected pretty much everyone in the group: young and old, men and women, light and heavy, drinkers and non-drinkers, supplements users and non-users, athletes and non-athletes.
Peanuts are not nuts, but when the researchers split the results up between 'tree nuts' and 'peanuts', there was no noticeable difference.
Nutritionists have long thought that nuts contain fatty acids that help improve the cholesterol balance. This might explain why nuts and peanuts protect the heart and blood vessels. But if you look at how broad the protective effect of nuts is they must contain other important bioactive substances.
