Paris, France--Eating nuts like walnuts, almonds, pistachios and hazelnuts twice a week is associated with a 17% lower risk of death from cardiovascular disease compared to consuming nuts once every two weeks, according to research presented at ESC Congress 2019 together with the World Congress of Cardiology.

“Nuts are a good source of unsaturated fat and contain little saturated fat,” said study author Dr. Noushin Mohammadifard of Isfahan Cardiovascular Research Institute, Iran, in a press release from the the European Society of Cardiology (ESC). “They also have protein, minerals, vitamins, fibre, phytosterols, and polyphenols which benefit heart health.”

“Raw fresh nuts are the healthiest,” added Dr. Mohammadifard. “Nuts should be fresh because unsaturated fats can become oxidised in stale nuts, making them harmful. You can tell if nuts are rancid by their paint-like smell and bitter or sour taste.”
