Study links higher nutrient intake with lower risk of mortality during 9.3-year median period

University of Connecticut, January 25, 2022


A study that utilized data from the National Health and Nutrition Education Survey (NHANES) found an association between having an adequate intake of vitamin E, iron, magnesium, potassium, EPA and DHA, essential amino acids and fiber and a lower risk of dying during a median follow-up period of 9.3 years. The study included 20,602 men and women enrolled in NHANES. During a median 9.3-year period, 3,539 participants died. The participants who survived were more likely to have reported a higher intake of specific nutrients. Notably, compared to participants whose magnesium intake was among the lowest one-third, those whose intake was among the top third had a 22% lower adjusted risk of dying from any cause, a 35% lower risk of dying from cardiovascular disease and a 29% lower risk of cancer death during follow-up. Magnesium wasn’t the only nutrient linked to a lower risk of mortality during follow-up; the top consumers of vitamin E, iron, potassium and fiber had 19%, 15%, 18% and 16% lower respective risks of premature all-cause mortality.
