From left to right: 1) A woman eats an apple, with visible cardiovascular system and digestive system. 2) Fresh vegetables, including tomatoes, peppers, broccoli, cauliflower and carrots, are high in fiber which helps keep blood lipid levels healthy. 3) Monounsaturated and polyunsaturated fats are better for heart health than trans fats and saturated fats. Good sources include those shown: nuts, seeds, olive oil and omega-3 fatty acids like those found in salmon. 4) A woman takes a vigorous walk with muscles, skeletal bones and heart visible.
