Fads, fakers and facts: who to trust for nutrition advice

A woman vlogs while cooking

There are millions of Instagram, Twitter and Facebook accounts all claiming to help you lose weight, eat better or find a miracle in your lunchbox. World Cancer Research Fund’s Courtney Savage chooses accounts you can trust.

Healthy eating and diets are a popular topic on social media, with a survey in 2022 finding more than 47% of people turn to social media as their main source of diet information, compared with just 21% who approached a nutritionist directly.

But how do we know who to trust on social media?

There are thousands of accounts online run by people claiming to be experts in the field. They are often pushing “evidence” and fad diets that aren’t exactly backed up by science – and may actually cause us harm if we follow it. A good indicator of trustworthiness is whether they’re a registered dietitian or nutritionist. Look for the following in their profile:

  • RD – dietitian registered with the Health and Care Professional Council (HCPC)
  • ANutr – associate nutritionist registered with the Association for Nutrition (AfN)
  • RNutr – nutritionist registered with the AfN and with more professional experience than an ANutr

If you’re unsure who to follow, check out some of our favourite nutritionists and dietitians on Instagram:
