Why is nutrition such a difficult topic to research?

613 views

There is a massive amount of conflicting research/information on nutrition out there. Eggs are great for us, eggs are clogging our arteries, eating carbs is good and gives us energy, carbs make us lethargic and fat. As someone who, after years of treating their body like crap, wants to make an effort and eat things that are good for me, it seems impossible because at this point I feel like whatever arbitrary statement about food you take (like, eating 1/2 green apple increases your metabolism but only on Tuesdays and Fridays), you will find some type of research “confirming” it. Why is it so hard to have concrete research/evidence of what is good for our bodies and what isn’t, at least generally? Isn’t it science? How are we supposed to know what to eat??

I don’t think that’s specific to nutrition. Understanding the relevance of each study is not easy. If you want to confirm your own bias then it’s easy to find that one study that says it and run with it (looking at you antivaxxers), even if the results were never reproduced. In the case of nutrition, it’s also more interesting for researchers to study a group for 10 years than it is to put them in the lab and answer questions only once (contrary to smth like game theory). So the research takes time and relies upon people sticking to it.
