Imagine how rigorous nutritional science can be when state-of-the-art double-blind scientific tests are pretty much impossible or extremely expensive to do, and when there is a lot of $$$ interest and lobbying in presenting one outcome or the other. Nutrition is not rocket science, we are all expert in eating and especially in how our body reacts to certain food types, yet we take studies of abysmal quality for granted and preach them to our fellow human as if they were the ultimate truth. I can say I'm going to run a marathon naked in Antarctica and everyone would cheer me, but if I mention I'm going vegan, carnivore or adding some butter or tofu to my cheeseburger, everyone, from both camps, is ready to point out why I am killing myself and on the way to premature death. Yet they are not speaking from experience, but mostly from hearsay from their favourite echo chamber. I've stopped caring what common wisdom around nutrition is, and since I've started listening to how my body reacts I feel much better, healthier, and I roll my eyes every time I read the latest "nutrition" article or comment thread posted on here or anywhere else. We're still in the middle ages of nutritional sciences.
