According to recent research, drinking coffee and eating peanuts, walnuts, and tree nuts have substantial benefits for heart health. People who regularly eat nuts have a lower risk of cardiovascular disease, while drinking coffee decreases the risk of heart failure and stroke.
A study published in the Journal of the American College of Cardiology is the largest study to examine the link between nut consumption and heart health. The researchers set out to examine the association between specific types of nuts and the incidence of cardiovascular disease.
The analysis examined over 210,000 individuals who had previously engaged in one of three major studies. The participants had self-reported on medical history, lifestyle, and health conditions every two years and the research team was able to follow up on the study subjects for up to 32 years.
The study revealed a consistent inverse connection between total nut consumption and total cardiovascular disease and coronary heart disease.
In addition, eating walnuts at least once per week was linked to a 19 percent lower risk of cardiovascular disease and 21 percent lower risk of coronary heart disease. Those who had eaten peanuts or tree nuts at least twice per week had a 13 percent lower risk of cardiovascular disease and a 15 percent lower risk of coronary heart disease.
Overall, participants who consumed five or more servings of nuts a week had a 14 percent lower risk of cardiovascular disease and a 20 percent lower risk of coronary heart disease than participants who rarely or never consumed nuts.
“Our findings support recommendations of increasing the intake of a variety of nuts, as part of healthy dietary patterns, to reduce the risk of chronic disease in the general populations,” said lead author Marta Guasch-Ferre.
Preliminary research reveals similar heart health benefits from coffee. An analysis was developed based on the long-running Framingham Heart Study, which provides information about cardiovascular health based on certain diets.
The analysis revealed that drinking coffee has a significant effect on cardiovascular health. Compared with non-coffee drinkers, those who drank coffee had a reduced risk of developing heart failure by 7 percent and stroke by 8 percent with every additional cup of coffee consumed per week.
The findings of this study are being presented at the American Heart Association’s Scientific Sessions 2017.
