Everyone knows that achieving or maintaining a healthy body weight is one key to preventing cardiovascular disease. But even experts don't agree on the best way to achieve that goal, with some recommending eliminating carbohydrates and others emphasizing reducing fats to lose weight. Few studies have investigated the effects of these specific macronutrients on cardiovascular health.
In a study published online in the International Journal of Cardiology, researchers at Beth Israel Deaconess Medical Center (BIDMC) examined the effects of three healthy diets emphasizing different macronutrients – carbohydrates, proteins, or unsaturated fats – on a biomarker that directly reflects heart injury. Using highly specific tests, the team found that all three diets reduced heart cell damage and inflammation, consistent with improved heart health.
"It's possible that macronutrients matter less than simply eating healthy foods," said corresponding author Stephen Juraschek, MD, PhD, Assistant Professor of Medicine at BIDMC and Harvard Medical School. "Our findings support flexibility in food selection for people attempting to eat a healthier diet and should make it easier. With the average American eating fewer than two servings of fruit and vegetables a day, the typical American diet is quite different from any of these diets, which all included at least four to six servings of fruits and vegetables a day."
