Can't remember the science now, but had been eventually persuaded by podcasts and online articles about the benefits of eating good fats for fuel rather than carbs, and specifically cooking in stuff that's solid at room temp. This stuff is amazing - delicious taste and aroma added to your meals, and even the aftertaste lingers in a fragrant, welcome way. I'm a convert, for sure. Will be ordering more than one tub next time! Great product.
