In order to produce a better nutritive milk, Scientist have induced human genes to around 300 cows.
Thus by doing so, cows are producing a so called " human milk" which helps to boost the immune system of a human child, or maybe the calf too.
It was argued it is not dangerous if done correctly, afterall, why would they induce genes that will harm the food source in which we consumes. Although many people are resistance to GM food, like ethical issue, or afraid of side-effects, these modified food can proven to be useful once proven to be safe, but it usually takes 10-20 years of experiment, even on humans, to see the side-effects as all these are accumulated in small amount.
However when consumed in small amount, won't it be passed out of the body if the body does not recognise it as a source of energy or nutrients?? if it recognise it as a source of nutrients or energy, wont it be the same, being absorbed normally? Having said that, unless it is in microbial secretion, may cause allergic reactions or hazards which is not yet discovered as things mutates over generation.
