No evidence needed of caloric value of any substance. If you know what's in it, calculating energy is easy.
Human milk contains 8grams of lactose per 100ml, lactose is 4cal/gram; protein is about 1,5gr/100ml, also at 4cla/gram. Fat is the big variable and offers most calories: 8/gram. Mean fat content is said to be about 4gr/100ml, but can vary from practical nil to way over 10gram/100ml.
on average 100ml of human milk will contain 8x4cal from lactose + 1,5x4cal from protein + 4x8cal from fat = 32+6+32=70 cal/100ml. according to my calculator 100ml is 3.38 oz, so that brings the math to 70/3=(about) 23 cal/oz
I have a crematocrit-machine and almost never test human milk below 22cal/oz, most average around 24-26 (term, healthy babies of any age)

>Has there been any recent evidence based research published regarding calorie content of breastmilk. I know that it varies all the time but I can't seem to get the fact into the neonatologist’s mindset that breastmilk is not 20kcal/ounce. So if a baby needs 22kcals it has to have a fortifier added because breastmilk 'is only 20kcal'. Of course I know that a creamocrit would be the answer but hospital won’t pay for one so I was wondering if there was anything published that I could provide to them so I can increase their education.
