Unfortunately, many of us struggle to meet our health goals, or face serious diseases later on in life. But with a wealth of online nutrition courses, you can gain the skills and knowledge you need to put this right.  

Whether you’re a serious athlete looking to smash your personal best with the right macronutrients, a couch potato struggling to stick to a diet or you're seeking to become a certified nutritionist, there’s an online nutrition course out there for you. I’ve delved into best nutrition courses, taking into account their certifications, user satisfaction and instructor expertise. Plus I've considered different dietary requirements as specialisms, from plant-based to the best courses for child nutrition or sports professionals.

So this best online nutrition course review will help you find the best option for you!. 

What is the best online nutrition course?

My top choice is Diet and Nutrition Coach Certification: Beginner to Advanced on Udemy. This is due to its well-balanced combination of nutrition science, coaching advice, impressive accreditation and great resources. It’s a great introduction to nutrition if you’re new to the field, giving a broad overview of everything you need from macronutrients to coaching skills without breaking the bank. 

My second choice is Fitness Nutrition Specialist from ACE Fitness. Coming from a respected and reputable organization at an accessible price, it provides an impressive qualification to pursue a career in this field, giving a great scientific backing and interpersonal coaching skills. 

Other courses on this list were chosen for the respected institutions they are affiliated with, or for their interesting specialisms such as holistic nutrition, child nutrition and vegan nutrition. Whilst others were chosen for their interesting perspective on nutrition, such as Michael Pollan Teaches Intentional Eating on MasterClass. A MasterClass subscription will give you access to this great course, as well as hundreds of others on a wide variety of topics.

Michael Pollan Teaches Intentional Eating

Platform: MasterClass | Teacher(s): Michael Pollan | Length: 13 video lessons totaling 3 hours and 18 minutes

This unique class offers something a little different to most nutrition courses. Rather than offering medical or detailed health advice, acclaimed food journalist Michael Pollan frames food as an expression of value, emphasizing the interconnectedness of food, health, environment and community to encourage us to align our values with our eating. Tackling the American food system and the perils of the Western diet, Michael Pollan explores alternative food systems and encourages balanced, intentional eating while balancing caffeine and sugar consumption.

  • Michael offers plenty of assignments along the way to create an engaging, thoughtful course, and help you incorporate his lessons into your daily routine
  • The ‘field trip’ to a regenerative farm offers a great way to break up the content, and provides a great insight into food production systems


  • Michael Pollan is a journalist, not a medical professional, and this course is more about reframing your relationship with food than giving you scientific data about the perfect meal plan. However, Michael’s loose rules (‘eat food, not too much, eat mostly plants’) provide a pretty good starting point
  • You’re not going to get any certification from this class, so if you’re looking to launch a nutritionist career, then one of the other courses on this list might be better for you. However, this course is still a valuable, thoughtful addition to any nutritionist’s toolkit.
