Hehe ... I can tell you for sure that there is no such thing. At present, there are many training institutions, and the cost is a bit high, but the certificate is still ok, unlike the training certificate mentioned by my friend upstairs, if the whole country uses a good training institution certificate. Nowadays, many universities offer nutrition courses, but many of them are chaotic. In the end, you may not even understand the basic catering, and the certificate is only a diploma. When I was chatting with a college student studying nutrition, he actually said that he had learned six books, each of which was a little bit, and finally he couldn't learn anything, hehe ... not as comprehensive and systematic as the training center. At present, the country has no clear regulations on nutrition, and only training institutions are training, so in recent years or later, they can only participate in learning in training institutions.
