Should you believe your PT or MD with nutrition?

Most of the books and documentaries about nutrition are biased, false, and sometimes even dangerous.
What hurts me the most is when PTs (personal trainers) get information from such books and then spread it among their clients.
“My PT/MD told me. He must be right!”
Unfortunatelly no. The problem is that nutrition is relatively simple until we get deep into it. To interpret specific nutrition studies, one need to understand science, scientific evaluation, and often the nuancies of the area of research to be able to interpret it.
A gynecologist is MD just like heart surgeon but you would not go to a gynecologist for advice about heart disease.
According to this study, water boils at 98°C! We were all wrong! We should not believe the big physics agenda!
For example I could claim that according to this study, water boils at 98°C! We were all wrong! We should not believe the big physics agenda!
  • Does it change how you boil water?
  • Does it change the fact that water boils?
(The boiling point of water changes based on atmospheric pressure.)

What happens in Petri dish, stays in Petri dish!

Similar claims are done all the time in discussions, books, podcasts, blogs, and on the social media. Inlfuencers, supllement companies and authors use scare tactics and misinformation to push their agenda.
For example they cherry pick studies (when you only pick the studies or part of the studies that support your claim and disregard everything else), or frame them in a specific context and then exagerate it, or generalize it to support their claims.
These techniquest are used as a fearmongering to grab attention and to sell you stuff.
Vegetables contain antinutrients, which lower the absorption of vitamins and minerals. Therefore you should avoid vegetables! Follow my low vegetable diet instead!
It is true that anti-nutrients prevent absorption of certain vitamins and minerals and so it might seem logical to avoid foods containing antinutrients.
But at the same time vegetables contain other substances that enhance mineral and vitamin absorption. Processing of food such as cooking also makes nutrients more available, while “disabling”or removing antinutrients. In the end, there is no problem with consuming foods high in antinutrients but it can be made to seem so if we disregard the later part.

When you are not educated in this field, it is easy for you to believe someone who has credentials in front or after their name.

I am confused! Who can I trust?

A good rule of thumb to apply when reading,watching or listening to information about nutrition is to simply ask the following questions:

Is this information against the general advice?

For example, we know eating vegetables and fruit is health promoting. Therefore advice to reduce vegetables intake should sound an alarm 🚨

Is the advice/research applicable?

Often, you can learn about some specific, exciting research, but then you find out you cannot apply it. Therefore it has zero value to you.

Consider the source

When we see credentials like MD, PT, PhD. we can easily assume that the person knows what he or she talks about. But if their credentials or work is not in the area he/she talks about, it is a warning sign.
P.S. I apreciate all the PTs and MDs who refer to other professionals or keep educating themselves from good sources to serve their best!
