The nutritionist exam is a national vocational qualification exam, so there are requirements for those who take the exam. Different grades have different requirements for working years. Prove that you are qualified to take the exam through your employment certificate. If you are a student in a related major, you can apply for an internship certificate. If you can't do it yourself, you can ask someone for help. If you want to participate in institutional training, you can ask them to provide it for you. If you are Xi 'an's suggestion, you can consider Shaanxi Public Vocational Training Center, which is quite good ~!
