The main types of food a 90-yer-old should eat involve a variety of fruits, vegetables, low-fat or fat-free dairy, cooked lean meat and poultry, cooked seafood and eggs, beans, lentils, nuts, seeds, and whole-grain foods.

Due to the high proportion of vitamins A, E, and D and omega-3 fatty acids, eggs are an ideal food to include in your diet if you are 90 years and older.
