Fat intake will aggravate the obesity symptoms of middle-aged and elderly people and easily lead to cardiovascular diseases. Therefore, middle-aged and elderly people should eat less foods with high fat content during weight loss, and it is best to replace animal fat with vegetable fat.

2. Ensure adequate intake of cellulose.

Middle-aged and elderly people's digestive tract exercise ability is reduced, and constipation symptoms are prone to occur. If you want to treat constipation symptoms fundamentally, you must ensure that you take enough cellulose. Cellulose can not only relieve constipation, but also prevent hypertension, arteriosclerosis and diabetes. In coarse grains, algae, vegetables and other foods, the content of cellulose is relatively rich, and middle-aged and elderly friends can usually eat more.
