● Myth 1: Meat and Bone Soup for Calcium Supplement

[Analysis] Many patients with fractures like to use Meat and Bone Soup for calcium supplement, but the calcium content in Meat and Bone Soup is not high. Some people have experimented with cooking soup with 1 kg of meat bones for 2 hours. The calcium content in the soup is only about 2 mg, but the fat content of the meat bone soup is very high because there is bone marrow. The recommended daily intake of calcium for adults is 8 mg, and patients with fractures need more. It is far from satisfying the need to supplement calcium with meat and bone soup. Milk or calcium preparation should be used to supplement calcium. ● Myth 2: Patients in kidney calculi can't supplement calcium < P > [Analysis] In kidney calculi, calcium oxalate is mostly deposited in urine, mainly due to excessive intake of oxalic acid, which combines with calcium to form calcium oxalate and form kidney calculi when urinary tract is excluded. The key to prevent and control kidney calculi is to reduce the intake of foods containing more oxalic acid, such as spinach and bamboo shoots. Even if you eat them, you should boil them to remove the oxalic acid content. ● Myth 3: Fish without scales have high cholesterol < P > [Analysis] This summary is not comprehensive enough. It is true that some fish without scales have high cholesterol, such as whitebait, river eel, loach, eel and cod, but not all fish without scales have high cholesterol, such as hairtail and shark, which are similar to grass carp, pomfret and perch with scales. [Gourmet hero] ● Myth 4: The less carbohydrates diabetics eat, the better < P > [Analysis] Blood sugar is related to carbohydrate intake. Diabetic patients should properly control the intake of carbohydrates to prevent blood sugar from exceeding the standard. Normal energy intake should be maintained under the condition of maintaining normal weight, and carbohydrates should still account for 6%~65% of energy. Diabetic patients should eat foods rich in dietary fiber every time, such as oatmeal and fresh vegetables, so that carbohydrate digestion and absorption are slow, blood sugar will not rise too fast, and the level is relatively stable; If you simply eat less carbohydrates, it will make digestion and absorption faster, and your blood sugar will rise quickly and last for a short time, which is prone to hypoglycemia, palpitations, dizziness, cold sweat and so on. ● Myth 5: You can lose weight only by eating vegetables at night < P > [Analysis] The main reason for simple obesity is that energy intake is too high and consumption is too small, and energy turns into fat accumulation in the body, forming obesity. The three nutrients that produce energy are protein, fat and carbohydrate. One gram of fat can produce 9 kilocalories, and one gram of protein and carbohydrate can produce 4 kilocalories. Eating less can reduce the intake of carbohydrates, which can reduce the intake of energy, but eating more dishes will increase the intake of fat, resulting in higher energy, which will not achieve the purpose of losing weight, but will make the intake of nutrients unbalanced and unhealthy.

● Myth 6: Old people drink milk to cause cataracts

[analysis] Some people say that because milk contains cysteine, it is easy to damage the lens of the eyes after oxidation, which makes the lens turbid and cause cataracts, so it is not suitable for old people to drink milk. In fact, milk is rich in calcium, which is an important source of calcium in the diet. Casein in milk is also a high-quality protein, which is beneficial to the absorption and utilization of the human body. There are many factors in the formation of cataract. Old people have low antioxidant capacity, so they can supplement antioxidant nutrients, such as vitamin C, vitamin E, β-carotene, trace elements selenium, zinc and other nutrients to prevent senile cataract. ● Myth 7: Winter tonic should be supplemented by protein Editor: admin
