Every week medical researchers are revealing new discoveries in our diet and its impact on our length and quality of life.  

This week researchers in both the United States and China evaluated the diets of more than 200,000 people. Their findings, published in the Jama Journal of Internal Medicine this month, found that nut consumption was related with a lower risk of premature death from heart disease and other causes. 

The March 2nd study, featured in US News and World Report, lends support to previous evidence of the immense heart health benefits of nuts. 

Researcher Dr. Xiao-Ou-Shu , associate director of global health and professor of medicine at Vanderbilt University, adds their findings are "based on an observational study".

The team of researchers cannot prove cause-and-effect with certainty. 

She continues: "That said, the totality of evidence from nutrition and health research  suggests that nut and peanut consumption can be considered a healthy lifestyle choice."The subjects who ate the most nuts, peanut butter and peanuts reduced their risk of early death from heart disease and all other causes by about 20 percent, compared to the subjects eating the least. 

"Because peanuts [which do not grow on trees] are much less expensive than tree nuts, as well as more widely available to people of all races and all socioeconomic backgrounds, our study finding suggests that increasing peanut consumption may provide a potentially cost-efficient approach to improving cardiovascular health," Dr. Shu said.

"Nuts are rich in nutrients, such as unsaturated fatty acids, fiber, vitamins, phenolic antioxidants, arginine and other phytochemicals," Shu said. Which are all known to help heart health, she said, by decreasing inflammation.
