At present, the state recognizes two dietitian certificates, namely, the dietitian certified by the National Health Commission and the registered dietitian in nutrition and food hygiene established by the Chinese Nutrition Society. These two dietitian certificates have high authority and professionalism, so the state only recognizes these two certificates.

The first is the nutritionist certified by the National Health and Wellness Commission (NHWC), which requires the nutritionist to undergo formal training and examination, and to pass the review before obtaining the certificate. This certificate is the only one in China authorized by the National Health Commission to certify the qualification of dietitians, which has a high degree of authority and professionalism. Dietitians with this certificate have strong clinical practice and scientific knowledge, and are able to provide individualized nutritional counseling and guidance to help people develop reasonable dietary plans and reduce the risk of disease.

The second is the nutrition and food hygiene registered dietitian set up by the Chinese Nutrition Society, which also needs to go through formal training and examination, and obtain it after passing the review. This certificate is issued under the authority of the Chinese Nutrition Society and is the main constraining certificate for dietitian practitioners in China. The qualification of this certificate reflects the individual's professional skills and abilities in the field of nutrition and food hygiene.

In summary, the state only recognizes two types of dietitian certificates, those certified by the National Health Commission and those established by the Chinese Nutrition Society. Both of these certificates are authoritative and professional certificates that can play an important role in nutritional counseling and guidance, ensuring that the dietary advice and counseling services provided by dietitians are reliable and scientific. Therefore, if you want to become a dietitian, it is recommended that you choose to certify authoritative certificates and actively participate in relevant professional training and knowledge updating, in order to expand their own professional field and enhance their level of competence.
