There are two culprits when it comes to asthma: cow's milk and lack of water. Cow's milk is the leading cause of asthma, especially in infants, and nearly everyone who stops consuming dairy products for 30 days sees their asthma improve dramatically or disappear altogether. Lack of water is the second leading cause, and the sad fact is that most Americans live their entire lives in a state of chronic dehydration. The constriction of capillaries in the lungs is the body's way of reducing water loss during respiration. This physiological response is frequently and inappropriately diagnosed as asthma by doctors. What doctors need to be prescribing is water, not steroids, and they need to be telling their patients to drink only water, not soft drinks, not juice, not punch, and certainly not cow's milk.
It almost sounds too simple to be true, but I believe that avoiding all dairy products and drinking nothing but fresh water will reverse more than 95% of the asthma now being observed in the population. Of course, it only works if you actually do it. Asthma cannot be reversed by simply thinking about giving up soft drinks and cow's milk -- the person actually has to take the action. Sounds stupid, I know, but you'd be surprised to learn how many asthma patients will agree with all this and never follow a word...
