Whilst on travel and washing up cups with residual milo, Mr H highlighted that the residue was very oily. Compared to formula milk which was not oily, it sparked off a discussion as to why oil was added to milo.
I did a search on Google and results were surprising. Some people commented that milo made locally contained palm oil while the Australian milo recipe did not contain palm oil and therefore did not leave an oily residue.
Guess it meant that milo was more fattening than what it should be.
