If this is truly all the body needs, then how do they deal with uptake issues? There are several things that compete for uptake in the body in the same way that oxygen and carbon monoxide compete when binding to the hemoglobin in your blood.
E.g.:
- Omega-6 fatty acids will push out the much better Omega-3 fatty acids. IIRC, the recommended ratio is 2:1 (Omega-3 to Omega-6)[1].
- Absorption of iron is inhibited by calcium.
[1] FYI, most oils have a ton of Omega-6, and not much Omega-3. One exception here is coconut oil, which has little of either.
