Dietary needs vary from one person to the next. However, diets must include fatty acids, amino acids, calories, vitamins and minerals to maintain good health. A diet that is deficient in any category may lead to health conditions, such as low or high blood pressure, Type 2 diabetes and certain cancers. Always consult with your physician or dietitian before making changes to your diet.
Fatty Acids
Omega-3 fatty acids are essential nutrients to your health. This type of fat is not produced by the body, so you must get it from your diet. Omega-3 fatty acids are necessary for many functions, such as building cell membranes and blood clotting. These fatty acids contain vitamins and minerals and proteins that may reduce your risk of developing certain health conditions such as heart disease. Walnuts, fish and green vegetables like spinach and lettuce are good sources of omega-3 fatty acids.
Amino Acids
Like fatty acids, amino acids are not produced by your body and must come from your diet. There are 20 amino acids, only 10 of which your body produces. According to the Biology Project, failure to obtain an adequate amount of even one of the 10 essential amino acids that your body does not produce will result in degradation of your body's proteins and muscles in search of the amino acid needed. Foods from animal sources, such as eggs, chicken, fish, beef, pork and dairy products are generally rich in amino acids.
Calories
Your body uses calories as its energy source. According to the University of Maryland Medical Center, the number of calories in your diet refers to the amount of energy your diet can provide for your body. It also states that a well-balanced diet will provide a sufficient number of calories while providing the recommended nutrients. Every type of food has its own number of calories. Your recommended daily caloric intake depends on your age and weight.
Vitamins
Vitamins are essential in the building, function and maintenance of many bodily functions, such as your nerves, brain and your eyes. For example, vitamin A is necessary for eye health. Eggs and carrots are good sources of vitamin A. Citrus fruits, such as oranges, are good sources of vitamin C, which is needed for the building and repair of collagen. Your body needs vitamin D to build strong bones and teeth. Milk, cheese and yogurts are all good sources of vitamin D. In addition, vitamin D can help protect you from developing osteoporosis.
Minerals
Your body relies on many minerals for various functions. The clotting of blood and the contraction of your muscles relies on calcium. Your body needs iron to carry oxygen to the cells of your body. Potassium is needed by the organs, tissues and the cells in your body. It is also essential for a properly functioning heart. A diet that is missing any of the vital nutrients may lead to certain health conditions.
