If Hunan cuisine is the representative of "salty, spicy and greasy", then other cuisines are not optimistic.

In restaurants, you usually put more oil, because "oiled meat is more fragrant and tender." In the kitchen of a well-known home-cooked restaurant in Beijing, Master Liu, who has been a chef for more than ten years, told reporters while demonstrating that if you put less oil, the meat will be easy to fry and the taste will be much worse. In addition, the restaurant uses a big fire for cooking, so if you put less oil, the meat will be burnt in the pot. Not only that, many chefs are used to pouring a layer of bright oil on the dishes when cooking. "This is to make the dishes look good in the light." Master Liu said, "Look at the boiled fish and Maoxuewang in Sichuan cuisine. They are all soaked in oil. There is at least half a catty of oil in that basin. "

"Oiling, oiling and other methods will at least make the fuel consumption of each dish exceed 50 grams." Fan Zhihong, an associate professor at the College of Food Science of China Agricultural University, said: "If the surface of dishes is covered with bright oil, more than 45% of them will be ingested with the dishes. Although thickening can help the dishes taste and reduce the shrinkage loss of protein, it will increase the intake of oil, because oil will be ingested together with starch attached to the surface of the dishes. "

Lard cooking harms cardiovascular and cerebrovascular diseases.

"Actually, using oil is only one aspect of the problem." Shi Wanrong, a famous chef in China, a member of the Professional Committee of Famous Chefs of China Cuisine Association and deputy secretary-general of Beijing Cuisine Association, told the reporter, "Now many restaurants are cooking with animal oil (lard, etc.). Cooking at home has long been eliminated, especially Hunan cuisine. Almost two-thirds of the dishes are fried with lard. Animal oil is saturated fat, which is very harmful to cardiovascular and cerebrovascular diseases. "

A foreign study shows that eating out is related to weight gain, and western-style fast food has become an important factor to increase the risk of chronic diseases such as obesity. Domestic studies have found that there is a considerable correlation between residents' weight and the density of restaurants in surrounding blocks. The higher the density of restaurants, the more obese people there are in this area.

"Although the daily oil intake recommended by China Nutrition Society is 25-30g, the data in 2004 show that the daily oil intake per capita in China has reached 42g, far exceeding our recommended value." Cheng Yiyong, vice chairman of the China Nutrition Society, said that this must be related to people eating more and more in restaurants. The body fat content of people who eat out frequently or for a long time is obviously higher than that of people who seldom eat out. Under the comprehensive influence of unreasonable dietary structure and other factors, the prevalence rate of chronic non-communicable diseases such as obesity, hypertension and diabetes in China has increased rapidly.

Three ways to reduce oil intake

"In fact, people are eating more and more oil, which is a by-product of the improvement of living standards and the only way for people to move from backwardness to civilization." For such a result, Cheng Yiyong said that it was expected. High-fat food will give off fragrance, and there is nothing wrong with people's pursuit of delicious food. However, with the further development of our food civilization, catering operators and consumers should consider that it is most important to enjoy delicious food on the basis of health.

"The most important thing is to train chefs in nutrition knowledge and limit oil from the source." Cheng Yiyong reminded, but for people who often eat out, the following tips can also help you eat less oil.

First, with the help of the pictures on the menu. Nowadays, more and more restaurants offer illustrated menus, and the cooking methods can be seen from the pictures. For example, home-made tofu will be fried first and then fried, while slippery tofu has no frying process. There is also crab yellow tofu, which won't contain too much oil. For green vegetables, you can choose soup. Meat and fish can be steamed. Generally speaking, the simpler the process, the less oil.

Second, choose an oil-free staple food. If the food is greasy, it is best to choose coarse grains such as corn and sweet potato as the staple food, or white rice and clear soup noodles. Snacks that eat less oil, salt and sugar, such as pumpkin pie and scallion cake, often contain 30%-40% oil, which is more greasy than many dishes.

Third, vegetable oil control for 30 seconds. According to a survey published in Hong Kong's Ming Pao, a large lettuce leaf may contain 1 g of oil. Therefore, holding the food within 30 seconds after picking it up can effectively reduce the intake of oil, slow down the eating speed and be beneficial to health. Of course, you can also ask the waiter for a bowl of boiled water and rinse it before eating, which can effectively remove the grease on the surface. ▲
