What should the elderly eat three meals a day? The content and time of eating three meals a day are different, and the physiological process of the human body has also changed accordingly. A reasonable diet is good for health. Breakfast: adhere to the principle of low sugar and low fat, choose lean meat, eggs, vegetables, juice and low-fat milk, supplemented by cereals and pasta. Lunch: Mainly high-protein food. Spring, an American psychologist, observed that both men and women over the age of 40 are less energetic than those who mainly eat protein foods within 4 hours after eating carbohydrate foods (such as pasta). The secret is that protein will decompose tyrosine after entering the body, and will be converted into excited dopamine and norepinephrine after entering the brain, thus making people full of energy. Dinner: mainly high-sugar and low-protein food. Sugar can increase the secretion of serotonin and prevent insomnia. High protein foods such as meat and eggs should be restricted. Knowing what the elderly eat three meals a day, I suggest that the elderly can arrange three meals a day according to the above principles, but everyone's situation is different, so the specific diet should also vary from person to person.
