In fact, thousands of years ago, the Chinese people began to "vegetarian". Ancient people have long had "five grains as the main, five animals in moderation, should not lose beans, five vegetables and color, fruits and vegetables, supplemented by the" said, which "vegetarian" not only from the fear of ghosts and gods, is not only Buddhist rituals, which is more representative of the promotion of the concept of health. Believe in this dietary structure of the court royal family, dignitaries to their own actions to the world: like this meal, it is a status symbol, is a truly healthy lifestyle!　　Nowadays, "vegetarianism" is gradually forgotten by Chinese people. Chen Junshi, academician of the Chinese Academy of Engineering and researcher at the Nutrition and Food Safety Institute of the Chinese Center for Disease Control and Prevention (CDC), said in a telephone interview with a reporter from the Life Times, "Many people now believe that big fish and meat and delicacies from the sea are synonymous with 'affluence' and 'progress' and that a vegetarian diet is a symbol of a healthy lifestyle. ' synonymous with 'prosperity' and 'progress,' and have begun to gorge themselves on 'happy' life." Some people even believe that only by consuming more meat can they be as tall as Westerners. Unbeknownst to them, this inadvertently let diabetes, coronary heart disease and so on "come to me". "And a diet based on plant foods can effectively prevent and control chronic diseases."　　But the trend of dietary changes in China is more oil, more salt, with such cooking methods made out of vegetarian meat, even if again "vegetarian", I am afraid that will be tasteless. In this regard, academician Chen Junshi believes that: "more oil, more salt and animal-based diets go hand in hand with the vice, must be abandoned. Even if the plant-based food, but also to control the total calories as a prerequisite, never think, as long as the vegetarian, more oil and salt does not matter." For example, in the United States, vegetarians borrow from Chinese recipes by replacing fried vegetarian spring rolls with baked (or steamed) vegetarian spring rolls. Academician Chen Junshi also emphasized that vegetarianism must also emphasize the collocation of reasonable, "some people just eat grains and vegetables, which will not work, soy products must be hitched in, so that the intake of protein is not worse than the protein obtained from eating meat, nutrition is more comprehensive." In the USDA nutritional guidelines for vegetarians, experts also recommend that vegetarians diversify their food, paying particular attention to the intake of food high in vegetable protein, but also eat more food rich in iron, calcium, zinc and vitamin B12.
