Lets keep in mind that saturated and unsaturated are only simple terms refering to a fats temperture relationship, and we all should know how coconut fat was erroneously missrepresented as an unhealthy fat because of that temp relation. Many Drs still think this and tell patients to not use it for fear of saturatedness.
Dr J Tennant is current on this. He shares it this way.
With fats there are different lengths of molecules involved.
Short, medium and long chains is the common term. Lipids, plant or animal, fall into one or the other or a blend.
The important thing is to know which is which and that our bodies are 20% fat and so we need to eat that much fat to stay at the peak of health. Also our fat is found in our cellular membrane, which is the cells brain, and in our nerves and brain.
The example is that of a house. One length fat type we need for the structural arrangment, another length fat type we need for the basic overall covering and one length fat type we need for the windows.
It is important we get all three in the correct ratios. If we have too much of one or the other or we have too little of one or the other our house will be build improperly and we will suffer because if it.
This is why just adding olive or fish or flax or hemp or coconut oil, any particular oilm isnt enough and if we add too much we have unintended consequences.
When farmers stopped feeding cattle grass and instead fed grain, the fat ratios of cattle changed and thus another way that modern methods have wrought change and unintended consequences.
Two of the correctly fat ratioed foods for us are mammal milk and marine plankton.
and also re: the elephant(and the other herbivores) in the original notes. The elephant is eating chlorophyll, pure ballanced complete amino acids, vitamins and minerals, no proteins, cept for a very small amount in that bannana tree he is eating.
The classic answer to the ques of how much protein do we need to eat is, none.
