The key to eating a healthy diet is limiting unhealthy foods and replacing them with healthier ones. For example, swapping out unhealthy trans fats with unsaturated fats is a great way to improve your health. However, switching animal fats for refined carbohydrates will not do much to improve your mood or lower your risk of heart disease. It is also important to consider the fact that manufacturers often hide unhealthy fats and sugar in packaged foods. It is important to include foods high in protein and calcium in your diet. Dairy products also contain B vitamins and iodine. However, choose low-sugar dairy products when possible. In addition, look for alternatives to dairy products that are fortified with calcium and other vitamins and minerals. Lastly, choose healthy fats over saturated fats. A healthy diet includes a variety of foods from each food group. This balance provides the body with a broad range of nutrients. It also helps reduce your risk of developing chronic diseases. In addition, it keeps meals interesting. You can also include some discretionary foods that don't fit into the 5 food groups. These foods are sometimes called junk foods. The key to a healthy diet is to limit your intake of saturated fats and increase your intake of unsaturated fats. These types of fats can be found in vegetables, oily fish, and avocados. When cooking, avoid using butter or oily spreads and use vegetable oil instead of dairy products. You should also choose lean cuts of meat. Fat is high in calories and can lead to heart disease and tooth decay. To limit the amount of saturated and trans fats, you should limit your intake of these foods to less than 10% of your daily energy intake. Saturated fats are a good source of energy, but too much can raise cholesterol levels. However, replacing saturated fat with unsaturated fats can reduce your risk of cardiovascular disease. Starchy carbohydrates should make up about a third of your diet. Starchy carbohydrates include cereals, bread, and potatoes. Try choosing wholegrain varieties of these foods instead of refined or white varieties. This will help you feel fuller longer. You can also try adding more fruits and leafy vegetables to your meals if you don't feel satisfied. Eating a healthy diet may be challenging but the key is to eat foods that promote health. Plant-based foods are great sources of antioxidants and omega-3 fatty acids and can help to reduce your risk of disease. Also, limiting salt is important for your health. The WHO recommends limiting your intake of these foods, as well as increasing your intake of other healthy foods. The key to eating a healthy diet is ensuring that you consume the right macronutrients, adequate micronutrients, and adequate hydration.
