If medium-chain fatty-acids are so good for us, how come human milk is mostly made of long-chain fatty-acids? Is there a difference between children and adults in terms of nutritional needs?
It is my understanding that medium-chain fatty-acids (especially abundant in coconut oil) are easily digested and utilized as a source of energy, and thus considered a great choice in general, but especially for people with digestive, metabolic, and neurological problems.
Now, I have found this quote "The milk fats of man, dog, and guinea pig, [are] largely made up of long-chain fatty acids... The milk fats of cow, sheep, and goat, [are] rich in short-chain acids... Horse milk, ... contains large amounts of medium-chain fatty acids..." (Source: http://www.jlr.org/content/8/5/473.abstract)
Short- and medium-chain fatty acids are similarly digested: "[s]hort-chain fatty acids, just as medium-chain fatty acids, are taken up directly to the portal vein during lipid digestion, in contrast to long-chain fatty acids, which are packed into chylomicrons and enter lymphatic capillaries and enter the blood first at the subclavian vein." (Source: http://en.wikipedia.org/wiki/Short-chain_fatty_acid)
How is it possbile that human milk has a less-than-ideal fat composition when compared to that of horse/cow/goat? Or is the hype around medium-chain fatty-acids exaggerated? Or am I getting something wrong?
