A recent study confirmed what we probably all already know: Women who don’t smoke, have a body mass index lower than 25, exercise at least 30 minutes a day and eat a Mediterranean-style diet have a significantly lower risk of sudden cardiac death.
In the Nurses’ Cohort Study that followed 81,722 women from 1984 to 2010, questionnaires were assessed every 2 to 4 years. The Mediterranean diet includes a high intake of fruits, vegetables, nuts, whole grains, fish and moderate alcohol. The study found an inverse association between all 4 low-risk lifestyle factors and a lower risk of sudden cardiac death. Women at low risk for all 4 lifestyle factors had a 92% lower risk of sudden cardiac death than women at low risk for none of the lifestyle factors.
Commentary: Researchers commented that 79% of sudden cardiac death may be due to unhealthy lifestyle practices in women who do not have a diagnosis of coronary heart disease. Sudden cardiac death causes more than 50% of all the cardiac deaths and is occurs more often in women. These study results will hopefully motivate us to live healthier lifestyles.
