What should the elderly eat to live longer?

　　It is right for the elderly to choose a vegetarian diet, but problems may arise if they choose improper vegetarian recipes. As living beings, humans need to take in a variety of nutrients. Look at nature, there are so many species. Simply eating green leafy vegetables such as Chinese cabbage and Chinese cabbage is obviously not nutritious enough.

　　For those who use a vegetarian diet to delay the aging process, it will be better to choose more seed foods, because any seed contains a complete life. Compared with seeds of the same volume, the nutritional value of seeds is much higher than that of vegetables.

　　Seed foods can be seen everywhere in life, such as rice, flour, corn, barley, millet, sorghum, and beans; there are also potatoes that can sprout when buried in the ground, such as sweet potatoes, yams, potatoes, white radish, carrots, etc.

　　To make vegetables delicious, a lot of oil is generally required. Nowadays, there are a wide variety of edible oils in supermarkets, and they are relatively cheap compared to ordinary people's incomes, so eating oil is not a difficult task. It was different in the past. There was very little oil at home, and the vegetables were boiled in water, which was not delicious at all.

　　On the contrary, foods such as cereals and potatoes rarely use oil, and when cooked casually, the aroma fills the house and arouses appetite. Best of all, they are more filling than vegetables. For thousands of years, our ancestors have relied on seed foods as their main rations, with vegetables only as supplements.
