why need to avoid dairy product and some tips

as u guys know,dr ali advised basil not to take any dairy product yet..cause last visit to dr ali,he had this cough and phlegm again...we did some research(thru mr google of course),and we found out -avoiding dairy products is one of the tips for phlegm and coughed!

We have a great build-up of mucous nowadays and there are many reasons for this congestion. Air pollution is one and the food that we eat is another, especially dairy foods. The most mucous forming product is milk and dairy products. Dr. William Ellis often said that dairy food is one of the worst foods for the human body. It is not made for human consumption. The animal protein intake is far too high for most people. When a baby is weaned from breast milk and put on cow's milk, what happens? Often infantile excema and asthmatic conditions occur. That child cannot cope with the mucous forming agent in cow's milk, but even more often with the level of protein which is nine times higher than in human milk. When I advise my patients with a nasty sinusitis or rhinitis to avoid dairy products, I have a tremendous job. I have to convince them. I almost have to blackmail them to stop, even when I tell them it's for their own good.......

suggestion from one of the clinic doctor was scott's emulsions when he is one year old . at that time we already introduce basil wt cod fish in his porridge( very smelly .. blerghh) and when we told him, he strongly agreed with what we r doing.cos he said -look at Eskimo people..they lived in very cold weather and they seldom encounter any health problem especially cold and cough.Someone did a research and they found eski-an eat lots of cod fish,and that is one of the reason why they stay healthy.

and do you know that Basil leave is good for phlegm and asthma too?
