There are a few reasons where there is so much misinformation when it comes to nutrition. It's an unregulated industry for starters. 

Anyone can set up a nutrition page or website and call themselves a nutritionist. The term nutritionist isn't protected by any laws (you cannot call yourself a dietitian unless you have the relevant qualification due to their work in clinical settings). 

As well as this most people think they know about nutrition. Everyone eats food. Most people are exposed to nutrition related headlines from news outlets, or they've read a book or follow someone on social media. Everyone chimes in when it comes to nutrition.

In contrast, if you were discuss how astronautics plots flight paths in space then most people realise this is outside their remit. 

How do we spot nutrition quackery? It can be tough, but here are some red flags to keep a look out for.
