A healthy heart begins with what you eat, and one way to shop for groceries wisely is to start with a list, a cardiologist recommends.

Reducing the amount of fat, sugar and salt (sodium) in your diet can help reduce your risk of obesity, heart attack, type 2 diabetes and other diseases, according to Dr. Susan Smyth. She’s medical director of the University of Kentucky’s Gill Heart Institute.

“Make your meal healthier by substituting foods with lots of color from natural sources [not artificial colors] for foods that are white or brown. Start in the produce section with fresh fruits and veggies, which are high in vitamins and fiber and low in fat,” Smyth said in a university news release.
