Maybe we have differing ideas of "general" but in healthy non-overeating people, the fatty acid profile in the body is reasonably close to the dietary profile.

Maybe we have differing ideas of "general" but in healthy non-overeating people, the fatty acid profile in the body is reasonably close to the dietary profile. There is some conversion like elongation and desaturation of essential fatty acids and you can also find some short-chain fatty acids from fermentation in the gut, but it takes excessive amounts of carbohydrates for de novo lipogenesis. Also, what else would the body do with dietary fat other than storing? A fatty meal would quickly overwhelm the capacity of the blood if there was no mechanism to quickly dispose of dietary fat.
