There are many fad diets, but the most important thing about a heart healthy diet, is establishing a healthy pattern of eating that you can sustain over time. The best steady pattern of eating for heart health is the Mediterranean diet, which is high in fruits and vegetables, whole grains, and healthy fats in fish and tree nuts. Use unsaturated cooking oils, like olive oil or canola oil, and minimize concentrated sweets, including sweetened beverages and processed foods.
The American Heart Association recommends at least 30 minutes of moderate intensity aerobic exercise, like walking or biking, five days a week. If you have a step counter, shoot for 10,000 steps a day. Despite amazing progress in the treatment of heart disease, it remains the number one killer in the US.
Eating well, and staying active, are the two most important things you can do to prevent heart disease and stay healthy.
