like any kinda medical advancement/invention/discovery, there will always be 2 sides of the coins.
Look at Da Vinci, look at Newton, the past so called "DISCOVERS/Inventors" Da Vinci had NO TRAINING in Science nor Medicine, yet he made drawings that impacted the revolution and understanding of Medicine. Gallileo and copernicious have always been persecuted by those who didn't believe in them even though they have made impt discoverys and inventions.
So, to answer the question whether milk is good? In general, milk is good in terms of NUTRITION, although the better tasting ones are usually full cream of high fat content.
However, the main problem and argument is that
1) Asians tend to have more lactose intolerance ---like me.... but i dun care
2) Cow's milk contains alot of bovine antigens (which the naive human body when exposed to it, MAY mount a drastic immune response to these antigens, hence effecting an allergic response).. if the situation is severe, it can lead to a systemic hyperallergy which is rather dangerous. Children with their naive immune system are usually more susceptible.
3) Breast milk from mothers to infants/children are the best form of nutrition...especially the "first milk" for those who are more familiar with this term. It usually contains alot of natural antibodies that the mother can pass on to her baby and this is one of the reason y most clinicians will encourage this practise.
so whats the conclusion? u've heard the pros and cons....
if u can't take cows milk, go for soyabean milk (like me)
if you have a baby, y not start him/her on breast milk?
Put it this way, Medicine is WHOLISTIC. Its not just the scientists/pharmacist/docs/nurse that is solely responsible for its practise/advancement.
u'll need engineers who can manufacture surgical steel, u need the pharmacist to derive the exact concentrations per dose of a drug, u need scientists to experiment with new ways to target say AIDS viruses, SARS-CoV, and even to utilize Stem cells blah blah blah.... last but probably the most important, u need the frontliners.... the nurses and physicians to explain and access the situation, to perform triage and to treat another fellow human
