1, is it good for the elderly to be vegetarian for a long time?
The rise of vegetarianism is not accidental. With the improvement of living standards, excessive intake of high-fat, high-protein and high-calorie foods will not only bring obesity problems, but also cause diseases such as hypertension, hyperlipidemia and hyperglycemia. In life, many old people are afraid of "three highs" and "staying away from meat dishes". After a long time, they find that their physical strength is not as good as before, and their health is getting worse and worse ... this is actually a disaster caused by long-term vegetarianism.
Long-term vegetarianism without paying attention to targeted nutritional supplements in other aspects can easily make the body lack of iron, protein and vitamins, which will undoubtedly lead to nutritional imbalance. In addition to malnutrition, it will also lead to a decline in muscle strength, which is prone to falls and fractures. At the same time, long-term vegetarian diet will aggravate anemia, osteoporosis and other problems, reduce the body's resistance, and it is difficult to resist the invasion of diseases.
2. What diseases are the elderly easy to get if they are vegetarian for a long time?
For the elderly who are vegetarian for a long time, the first thing is insufficient lecithin intake or decreased liver synthesis; Vegetarian food contains more plant fiber, which can reduce the reabsorption of bile acids and the concentration of bile salts. Secondly, vegetarians lack vitamin A and vitamin E, which causes gallbladder epithelial cells to fall off easily, leading to cholesterol deposition and stone formation.
Many elderly people usually think that after eating a lot of fat, cholesterol increases, blood lipids increase, and the probability of cardiovascular and cerebrovascular diseases such as gallstones increases. This understanding is correct. However, another factor of gallstones depends on the solubility of cholesterol in bile. Normal cholesterol is mixed and dissolved with bile salts and lecithin in bile according to a certain proportion, and it is not easy to form stones. This ratio is generally: bile salt plus lecithin/cholesterol should be 12: 1. If it is less than this ratio, gallstones may occur.
For the elderly, if they are blindly vegetarian, many nutrients in meat will not be ingested. In the long run, it will inevitably bring great trouble to the health of the elderly. Therefore, we suggest that we must reasonably match our daily diet and never let the elderly be vegetarian for a long time. Of course, for obese or hyperlipidemia elderly people, eating more vegetables and less meat is still very beneficial, but don't eat no meat at all.
3. The "formula" of healthy diet for the elderly
One is that drinking a bag of milk every day can effectively improve the generally low calcium intake in our diet. If you have milk intolerance, you can use yogurt, low lactose milk or double soy milk instead.
Second, the daily intake of carbohydrates is 250-350g, which is equivalent to 6-8 ounces of staple food, and can be increased or decreased according to the degree of personal obesity. If this person is overweight, the intake of staple food should be reduced.
Three refers to eating three to four servings of high-protein food every day, each serving means: 1 lean meat, 1 eggs, 2 pieces of tofu, 2 chickens and ducks, or 2 fish and shrimp. Fish and legume proteins are better.
Four fingers and four sentences: coarse and fine (with coarse and fine particles); Not sweet or salty (6-7 grams of salt per day in Guangdong, 8-9 grams in Shanghai, 0/4-/0/5 grams in Beijing, 0/8-/0/9 grams in Northeast China). Guangdong type is the best, followed by Shanghai type); Three, four, five meals (under the total control, the number of meals is more, which is conducive to the prevention and treatment of diabetes and hyperlipidemia); Seven or eight points full. Eating 500 grams of fresh fruits and vegetables with five fingers every day is an effective measure to prevent many diseases. Of course, you can use proper amount of cooking oil, dried fruits and condiments when you match meals.
The harm of long-term vegetarian diet
1, long-term vegetarian diet is not good for your health.
In vegetarianism, except beans, which are rich in protein, the content of protein in other foods is very low, and the nutritional value is low, which can't meet all kinds of energy needed by human body. Long-term vegetarianism, due to insufficient intake of protein and fat, will not only lead to malnutrition, but also significantly reduce the body's resistance, prone to infectious diseases, and also lead to osteoporosis and fracture.
2. Sexual life is not suitable for long-term vegetarianism.
Especially for women, long-term vegetarianism will make the proportion of carbohydrate, protein and fat in the body unbalanced, leading to indigestion, memory loss, decreased immunity, endocrine and metabolic dysfunction, and they are most prone to anemia and tumors. In addition, long-term vegetarianism will also lead to a decrease in gastric acid and digestive enzymes, a decrease in taste, and loss of appetite.
What nutrition do middle-aged and elderly people need to supplement?
1, calcium supplementation, the existence of calcium in the body is conducive to bone growth and repair. The loss of calcium in middle-aged and elderly people is very serious, which is prone to osteoporosis, so it is very important to supplement calcium. Eating dairy products, beans and oranges can make up for calcium loss.
2. Potassium supplementation can help middle-aged and elderly friends maintain normal blood pressure, and it is also very helpful to muscles and nerves. Eating potatoes, yogurt, fish, etc. can supplement potassium.
3. Supplementing crude fiber: it can promote gastrointestinal peristalsis and digestive function, and can also prevent constipation, diabetes and cardiovascular and cerebrovascular diseases in middle-aged and elderly people. Foods rich in crude fiber include celery, mango, pear and oatmeal.
4, magnesium supplement, it can improve the body's own immunity and resistance. Eating more hazelnuts and almonds can supplement the demand for magnesium.
