In today's world, there are nutrition experts everywhere. There are many different credentials, two of the most common being nutritionist and dietitian, so let's explore the differences:
Anyone can call themself a nutritionist because it is not a nationally regulated term. Since there are no national regulations around requirements to be a nutritionist, they cannot legally diagnose or treat medical conditions. There are ways for nutritionists to be credentialed, so if you're working with a nutritionist, look for licensures that prove they have a level of studying or supervised practice - such as BCNS or CNCB.
Registered Dietitians are regulated by the Commission on Dietetic Registration, as well as state authorities. In order to provide dietitian services, the RD must complete the following:
a four year degree in nutrition or dietetics
obtain 1200 hours of supervised practice
pass a national exam
complete ongoing continuing education
obtain state licensures
