Dispelling nutrition myths, ranting, and occasionally, raving

Eating to change your eye colour

I recently came across a post by David Wolfe (yeah, that guy) about the ability of a raw food diet to change your eye colour.

Apparently this is a thing ever since some raw food guru nutritionista chick made the claim that after changing from an unhealthy diet she cleared-up her constipation and her brown eyes became hazel/green.

Naturally I was skeptical. Even David Wolfe was. Yet, he somehow came to the conclusion that it was possible based on this article. The thing is, the article doesn’t actually support the claim that a raw food diet can change a person’s eye colour. It says that eye colour can change as we age, but this is generally referring to children, not adults and is unrelated to diet. It then carries on to state that significant changes in eye colour may be the result of a disease and anyone experiencing such changes should see an eye doctor. No mention of diet.

I did a little googling and found some other articles. None of which were written by anyone with any medical knowledge of eyes. Wolfe and this Vice article both mention “iridologists” which is pretty ridiculous. Iridologists are to optometry what phrenologists are to neurology. Essentially a great source of perhaps entertaining information but otherwise quackery. To be fair, even these iridologists seemed to think the notion of changing ones eye colour via diet was farfetched. Everything I could find through the googles was anecdotal.

I feel the need to voice my disappointment in seeing a dietitian’s name continually come-up in connection with this raw food eye colour change business. As dietitians we are obligated to provide evidence-based dietary advice. Neither advising people to choose a diet to change their eye colour, nor advocating for raw food diets for all are ethical for a member of our profession.

Next I turned to google scholar. Again, nothing. There is absolutely no scientific evidence of a relationship between diet and eye colour. Of course, it’s possible that, that research just hasn’t been done. And I will be happy to revise this post if a study is ever published showing that eye colour can be changed by switching to a raw food diet.

Even if eye colour can be changed by diet, who cares?! I mean, seriously. Having brown eyes does not mean that you eat unhealthily and are constipated. Having blue eyes doesn’t mean that you’re healthy and having regular bowel movements. Are we now judging a person’s health and habits based on eye colour? Could we get anymore superficial? Why would we want to go on an extreme diet just for the purpose of changing the colour of our eyes? A raw diet is not necessarily the healthiest choice. There are many reasons that we cook our food: to kill toxins and microorganisms, to increase absorption of nutrients, to improve palatability. Personally, I would rather keep my grey/blue eyes and enjoy my food.

  1. “Are we now judging a person’s health and habits based on eye colour? Could we get anymore superficial?” <– Love this line!

    Also – wanted to mention I've enjoyed the series last week for local food.

  2. The article calling Ondrej Matej a dietician is incorrect (nothing new there – most journalists have no idea about the differences in proper nutrition education and quackery). He’s not a member of the BDA or the AFN, which are the only recognized associations in the UK for nutrition. He went to something called the Complementary Therapy College. *sigh* Quackery is everywhere!

  3. He’s not a dietician or a nutritionist here in the UK (but journalists never seem to care about interviewing properly credentialled sources). He “graduated” from something called “England’s Number One Complementary Therapy College”. They also teach psychic healing…
