I often work with clients who have an interest in nutrition. They’ve read books, watched YouTube videos and have generally tried to apply some of the lessons they’ve learned to what they do. The aim of this short article is just to give a context for the field of nutrition and all of its complexities.
Once upon a time, if I wanted to understand something about nutrition I would need to travel to a place called “the library”. They still exist (so I’m told) but these days, if we’re researching a subject, we have the information right at our fingertips. Whilst this is amazing, like all things, there is a trade-off. We are now flooded with information which can make us feel like we’re drowning and we don’t know the difference between a life ring or ring doughnut.

There are 3 main types of nutritional information and if you like to keep yourself in the know, it’s important to arm yourself with this knowledge so you’re able to keep an open mind and not get stuck in one camp of a particular diet cult. If you’ve already started writing your placard which says “The Eye Ball Diet Gave me 20/20 Vision” , it’s too late, I can’t help you.

Researchers – These are the people in the lab doing the experiments and dealing with all the complicated elements required for a study:
- Recruiting participants (would you like to come and stay in a white box for two weeks while we feed you desiccated rat liver which we want to prove will increase your male pattern baldness?)
- The specifics of the study to obtain the result they’re looking for
- The equipment
- Loads of other stuff (I’m trying to keep this article readable!)
- This is science for scientists
Research Analysis – These are the people who look at the studies and think about a bigger context, real world application and all the nuances that only nerds think about. They have the greatest amount of freedom of the three to change their mind when new data comes in. This is the level with the best, most applicable information. As a Personal Trainer and Nutritionist, this is my preferred way to acquire information so that I can help my clients get the best results. But, as a reader, it’s time consuming and full of caveats so it can feel like you don’t know which direction to take.
Nutrition Books – Authors take all the information and present it in a way to the public in a nice, clean, digestible and interesting way. They’ve collated all the studies, trimmed off the fat and created a clear path that you can follow. This is where most people will get their information who consider themselves informed about nutrition which is great. There are potentially some big drawbacks though. Because they’re printed, they cannot be updated in real time. An author can update the book in their blog, but I don’t think most people are reading that, and they can release an updated version of the book, but by the time it comes to print, it may already be outdated. This is nobody’s fault, it’s just the nature of this medium. If a product is released alongside the book, then there is even more incentive for the author to stick with their narrative. Unfortunately, in this situation the incentive isn’t better science. For example, let’s say you’re selling a product (supplements or a device) which is based on your argument in the book you’ve published, what do you do if the central theme gets thoroughly debunked?

In summary, I think it’s great to learn about nutrition at any level and by understanding the benefits and limitations of each type, you can make better choices about the changes you want to implement.
