My subjective opinion about which product is the healthiest. Please don’t take this too seriously. In order to make an accurate ranking, one would have to visit each facility where the ghee is made, get to know the people making it, and evaluate the process much more deeply.
This is the kind of evaluation our society supports for things like financial investments, but we do not yet have collective support for putting that much research into evaluating a food product like ghee. Hopefully that will change because one should pay more attention to the quality of one’s food than to the quality of one’s investments. If the investments are good and the food is bad, one will not be around to enjoy the fruits of the good investments.
For now, I’m simply asking questions via email about the process of making the ghee and turning the responses to my questions into the ranking shown in the table. As I continue this investigation, and as I use the products more, my rankings may change.
