MONDAY, May 18, 2020 (HealthDay News) — For middle-aged adults without preexisting cardiovascular disease, eating a diet rich in fruits and vegetables over eight weeks is associated with lower levels of markers for subclinical cardiac damage and strain, according to a study published online May 19 in the Annals of Internal Medicine<\/i>.<\/p>\n
Stephen P. Juraschek, M.D., Ph.D., from Harvard Medical School in Boston, and colleagues conducted an observational study based on specimens from a subpopulation of 326 participants of the Dietary Approaches to Stop Hypertension (DASH) trial, which randomly assigned459 middle-aged adults without known preexisting cardiovascular disease to eight weeks of monitored feeding with a control diet typical of American eating patterns; a diet rich in fruits and vegetables but otherwise similar to the control diet; or the DASH diet, rich in fruits, vegetables, low-fat dairy, and fiber, with low levels of saturated fat and cholesterol.<\/p>\n
The researchers found that the fruit-and-vegetable diet reduced high sensitivity cardiac troponin I (hs-cTnI) levels by 0.5 ng\/L and N<\/i>-terminal pro-B-type natriuretic peptide (NT-proBNP) levels by 0.3 pg\/mL compared with the control diet. The DASH diet reduced hs-cTnI and NT-proBNP levels by 0.5 ng\/L and 0.3 pg\/mL, respectively, compared with the control diet. There was no difference noted in the levels of high-sensitivity C-reactive protein among diets. No difference was seen in any of the markers between the fruit-and-vegetable and DASH diets.<\/p>\n
“Our study shows that what we eat has an impact on cardiac damage and strain over eight weeks,” the authors write.<\/p>\n
