What nutritional supplements are good for a 90-year-old man?

A 90-year-old man generally does not need to take any nutritional supplements. He only needs to eat three meals a day. As the saying goes, it is better to eat early, eat full at noon, eat less at night, and should have a cup in the morning. Milk, an egg, two slices of bread, or a steamed bun, preferably some vegetables. You can eat some rice, chicken, duck, fish and other meats at noon. It is a combination of meat and vegetables and has comprehensive nutrition. In the evening, it should be lighter and eat less. Just a little easy-to-digest food is enough. As you get older, the food should be softer, which is better for the elderly to absorb!
