In the United States, the title of nutritionist can be applied to anyone who offers general nutritional advice. Nutritionists are not as regulated as dietitians, and even those who have no professional training can legally call themselves nutritionists. A nutritionist is a person who advises others on issues related to food and nutrition and their health impacts. Some people specialize in particular areas, such as sports nutrition, public health or animal nutrition, among other disciplines.
In many countries, a person can claim to be a nutritionist even without any professional training, education, or license, unlike a dietitian, who has a college degree, a professional license, and a certification for professional practice.
