It seems what is missing in nutrition is the ability to _measure the results on your own individual body_ . For example, you can take a blood test, find out you're deficient in vitamin D, supplement for a while, then take another blood test and see results.
But you cannot do that for most things to do with nutrition. You can't check your gut biome, see a problem, take a specific probiotic, then check again and confirm improvement, because we don't understand the gut biome well enough yet.
You can't do it with most supplements. And even when you can, we hardly ever do. Insurance is not going to be a big fan of it.
You also can't do it with switching from margarine to butter, or drinking more water, or whatever it is you think might help. Without some concrete measurable change that you actually measure, you're taking shots in the dark.
I hope wearable devices can make some inroads here, at least for low hanging fruit (easily measured, well-understood things).
