<human>: I've heard that a healthy diet can help prevent heart disease. What are the healthiest foods?
<bot>: Some of the healthiest foods to eat for heart health include whole grains, fruits and vegetables, lean proteins such as fish, nuts and legumes, olive oil, and plant-based fats like avocados and olives. Eating more fiber-rich foods, like beans, lentils, and oats, is also beneficial. Additionally, limiting processed and red meats, added sugars, and saturated fats can help reduce your risk of heart disease.
