During the epidemic period, Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, exported a lot of nutritional views, and golden sentences were frequently published. A few days ago, he said that "the diet and nutrition method dominated by refined carbohydrates is difficult to support us to live to be more than 90 years old!" "It has once again sparked a heated discussion. Why does Zhang Wenhong say this? What exactly is the "refined carb" we often hear about?
"Refining carbs" may increase the risk of disease
What is "refined carb"? Jiang Hong, a clinical nutritionist in the Nutrition Department of the First People's Hospital of Hangzhou, introduced that ordinary rice and flour foods belong to carbohydrates, while refined white rice noodles, cakes, desserts, milk tea, etc. are called refined carbohydrates.
In the traditional Chinese diet, the dominance of rice and flour foods is unshakable. Especially for the elderly, drinking some porridge or eating some noodles in the morning and evening is the "standard", and the dependence on them is far more than vegetables, fruits and meat dishes. From a nutritional point of view, this dietary pattern is understandable - most of the elderly have poor teeth, weak digestion, porridge and noodles are easy to digest, but it is not recommended. For example, due to the slowdown in metabolism in the elderly, the intake of refined white rice noodles will increase the absorption of carbohydrates, and when the intake exceeds the needs of human metabolism, it will be converted into fat and accumulated in the liver.
Vegan or into the "three high food"
Jiang Hong also found that the protein intake of many elderly people is far from enough. Studies have shown that people who have maintained a high daily intake of protein have a significantly lower risk of losing their ability to take care of themselves after the age of 90. Better protein sources include fish, meat, eggs, legumes, dairy products, nuts, tofu, and more.
"Now there is another phenomenon in the outpatient clinic that the number of fat elderly people is increasing." Through careful inquiry, Jiang Hong found that many elderly people have a worse metabolism than when they are young, but the intake is not low. Many elderly people even eat leftover food for their children, resulting in their increasing intake. Not only that, some elderly people's daily diet is too vegetarian, which often causes obesity. Surveys have shown that many people in the vegan population are diagnosed with hyperlipidemia every year. Because the elderly who have been vegetarian for a long time, nutrition and calories often come from oil, sugar, salt, etc., and the intake of animal protein is almost zero, and they will eat more refined white staple foods. Starch, oil, sugar, etc. have eaten too much, and vegans that were originally thought to be safe and healthy have become "three high foods".
The problem of "dry mouth" should be paid attention to
Why do many elderly people like to drink porridge and eat noodles? Maybe it has something to do with "dry mouth".
Sun Jianqin, director of the Clinical Nutrition Center of Shanghai Huadong Hospital, pointed out that after entering the old age, the salivary glands atrophy and saliva secretion decrease, which may be followed by problems such as difficult swallowing and indigestion. Therefore, many people like to eat porridge or noodles with soup.
In fact, the elderly with "dry mouth" can eat some sour foods such as fresh lemons and sour radishes before eating to promote saliva secretion. When eating relatively dry biscuits and bread, you can soak them in milk or soup before eating. In addition, insisting on tongue movements every day, such as stretching the tongue and turning hard, is conducive to maintaining tongue flexibility and taste function.
