From the perspective of professional qualifications, employment prospects and salary, the certificate of health manager is better. Although nutritionist certificate can also provide certain health services, health managers have richer professional knowledge and higher professional ability, which is more conducive to customers' health goals and easier to get higher salaries.

First of all, from the requirements of professional qualifications, nutritionists and health managers need to pass the relevant qualification examinations. The nutritionist certificate requires candidates to have basic knowledge of nutrition, be familiar with the theory and practice related to nutrition, have the ability of nutrition consultation and spread correct nutrition knowledge;

The requirements for the certificate of health manager are more stringent. The examination content includes not only nutrition knowledge, but also systematic health knowledge, scientific management methods, comprehensive nutrition guidance ability and understanding of health management practice. Therefore, from the requirements of professional qualifications, the certificate of health manager is stricter, which is more conducive to training customers to achieve the goal of good health.

Secondly, from the perspective of employment prospects, the employment prospects of health managers are better than those of nutritionists.

Because with the development of society, people pay more and more attention to health, and more and more people pursue a healthy lifestyle, which provides a broad development space for health managers. They can work in hospitals, gymnasiums, gymnasiums and other institutions, and also provide health management services in enterprises, nursing homes and other institutions, while the employment prospects of dietitians are limited. Most nutritionists can only work in hospitals, private clinics and other institutions.
