Could good interpersonal ties bolster the cardiovascular system? One study found that people who were socially isolated and lonely were more likely to have a heart attack or stroke than people with strong social networks. Being in a supportive marriage also cuts your risk heart disease, according to a 2018 study. Your relationships may actually matter more to your lifelong health than your cholesterol readings, suggest findings from the 80-year-old, ongoing Harvard Study of Adult Development. The researchers have discovered that the people who were most satisfied with their relationships at 50 were the healthiest at 80. Love, it seems, really is good for the heart.
In a study in JAMA Internal Medicine, researchers reported that people who ate the most sugar had a higher risk of death from heart disease, even if they weren’t overweight. Another study found that spending just three months on a sugar-heavy diet changed fat metabolism in healthy men, causing them to develop non-alcoholic fatty-liver disease, which boosts the risk of cardiovascular disease.
