Celebrate National Nutrition Month® with a few Healthy Eating Tips! Balance the plate with a variety of food. Aim to make half the plate fruits and vegetables, one fourth lean meat, poultry, or fish, and one fourth grains. Round it out with a side of low fat milk, yogurt, or cheese. Experiment with plant-based meals. Explore the idea of having a meatless day, by adding more beans, lentils, and vegetables in place of meat. Eat seafood twice a week. Fish and shellfish are nutritious, and contain heart healthy omega-3 fatty acids. Salmon, trout, oysters, and sardines are high in omega-3s and lower in mercury.
