As regards grassfed, well I eat raw wild game, not grassfed anyway.....
9 billion is already unsustainable if you look at the statistics. The Earth does not have infinite resources.
I am having trouble following your logic, you personally can afford to buy wild harvested animal foods, yet admit that wild harvesting of food is unsustainable and unable to feed the world? At the same time you are against using cultivated foods to feed the world, even those which which have a low environmental impact such as coconuts. I am sure you must admit that many of the other foods you consume that are produced through cultivation and wild harvesting, have a much higher negative environmental impact than the "monkey picked" coconuts I eat?
No, but, generally speaking, coconuts are nothing special and plenty of people can be healthy without ever eating a coconut. I just think one should not focus on one or two superfoods, when variety is usually healthier in the long term. Even SB goes in for a wide variety of raw organ-meats, for example.
Variety is the spice of life, but there are also many people who do well on just a small number of nutrient rich staple foods. Coconut may have some of the trace ocean elements which are lacking in my own land animal based diet. Its a matter of economics too, coconuts being much more affordable than eating three dozen oysters every week, or some other seafoods which are also unsustainably raping the oceans.
Goji Berries, bee pollen and other "superfoods" have no track record of being used as a primary staple for any group of people. And I would agree that most superfoods sold on the market are over hyped.
Coconut on the other hand has been used by island people for millennia in combination with a fish based diet with incredibly good results.
There are some groups of people who live almost exclusively off of fish and coconut, so there has to be some merit to its health food status.
I will admit that my own consumption of nearly two pounds of coconut butter a week is an anomaly and there may not be any precedent of a western born man who eats as much coconut as myself? Its also possible that I've become metabolically addicted to high levels of coconut fat and there is a dependency issue.( though its only an issue if there is a negative downside) and there are by far much worse food addictions out there.
Thinking about it even deeper it may be that coconut is what allows some of those tropical fishing peoples to thrive and mitigate the negative effects seen when people, other than the adapted inuit, get all their fats from pufa rich fish fat. The MCT in coconut could act in a way to balance fat metabolism in cultures heavily reliant on fish fats and proteins.
There are also people on this forum including Inger and myself who eat coconut regularly along with large amounts of animal fat, so perhaps it has some benefit for some people who eat larger amounts of all animal fats and protein in general?
