I’d like to figure out what nutrient profile to follow for my own recipe. The ones available in the DIY calculator vary greatly, and I’m not happy to just pick the most popular one.
Now, I understand that  everyone’s requirements are different, and  nutrition is not an exact science, and  nutritionists like to disagree about stuff. But I know we must have some facts, at least to narrow things down. Frankly, if I can’t base my choices on something solid, I don’t much see the point.
I’m aware that organizations (like the NHS in the UK, where I live) make health recommendations that are probably based somewhat on science, but they do vary from country to country, and I’m afraid they might be optimized for population health rather than individual health. For example (probably a stupid example, but it’ll make the point), they wouldn’t recommend 10 pieces of fruit per day, even if it was the healthiest choice, simply because the average person couldn’t keep that up. (I suppose it’s a place to start, though, and I will if I don’t find something better.)
So I guess my question is: What resources can you recommend, based at least partially on peer-reviewed research, to guide me in creating a good nutrient profile for myself? How much confidence do we have in the min and max amounts of existing nutrient profiles? Which ones are absolute, and which ones are open to interpretation? …
