Professor Hong Zhaoguang, a famous cardiovascular disease expert in China, pointed out that “the prevention of chronic diseases, especially cardiovascular diseases, should start from a reasonable diet, especially from the scientific use of edible oils.” According to the “Balanced Diet for Chinese Residents” formulated by the Chinese Nutrition Society, experts suggest that adults should not consume more than 25 grams of fats and oils per day. The survey shows that the per capita consumption of oil in Beijing, Shanghai and other cities has exceeded 80 grams, far exceeding the standard. Yu Kang, associate professor of nutrition at Peking Union Medical College Hospital, said that improper choice of cooking oil or over-eating can increase the risk of heart disease. Although many people know the theory of balanced diet, it is difficult to stick to it, how many people can do not exceed 25 grams of oil per day? Not only is oil over-eaten, but there are also some misconceptions about its consumption. Foreign studies also believe that the intake of cooking oil in about 25 grams per day is more reasonable, while China now consumes more oil, and the ratio is not very reasonable, the oil is beneficial to the human body unsaturated fatty acids are less. In addition, the temperature of the oil is too high when cooking and frying, the higher the temperature of the oil, the faster the oxidation of unsaturated fatty acids in the oil, some fat-soluble vitamins are destroyed, and the more nutrients are lost. So, the daily intake of fats and oils not more than 25 grams, that is, only half a tael, in the pursuit of dietary diversity today is not a bit unrealistic? How to grasp the amount of 25 grams of oil? According to Associate Professor Yu Kang, if you put 25 grams of cooking oil into a white porcelain spoon used for soup, it is just two and a half spoons. In addition, we can also choose a measuring jug with a scale when the oil jug will be filled with oil, so that you can always remind yourself not to use too much oil. Professionals recommend that people replace the large oil jug with a small one, or use a graduated jug to remind themselves of the amount of cooking oil they should consume.
