营养学家

Also known as nutritionists

A nutritionist is a person who advises others on matters of food and nutrition and their impacts on health. Some people specialize in particular areas, such as sports nutrition, public health, or animal nutrition, among other disciplines. In many jurisdictions, a person can claim to be a nutritionist even without any training, education, or professional license, in contrast to a dietitian, who has a university degree, professional license, and certification for professional practice.
