I have had a chronic cough for years, a form of cough-variant asthma. I also am on a salt-free, or low-salt diet. According to the author, a low or no-salt diet is a trigger for asthma symptoms,for your body can't hold in the water you need and becomes dehydrated. He explains as we become dehydrated we produce a large amount of histamine, which creates back pain,inflamed joints, allergies and asthma. He also explains how the lungs need water almost more than any other part of the body, and get tight and sensitive when the body lacks sufficient water. You also have to get off potassium, such as from orange juice and bananas for some people these are also triggers because they unbalance the salt/potassium balance.
To make a long story short, I started drinking the 8-10 glasses of water he recommends, with a pinch of salt (only use sea-salt) after every two glasses, and 1/2 t. a day of sea salt. Within 2 hours the tightness in my chest got better, and within one day I had completely stopped coughing. I kept thinking this was too simple to be true, but now, ten days later, I have almost complete relief from asthma symptoms.
This book really makes sense,and the information is presented well. Oh, and another benefit - all my lower back pain went away overnight, after months of pain, chiropractors, stretching, and everything else I could think of. He explains how lower back pain comes from dehydration, that occurs well before we even feel thirsty.
It does take a focus to drink that much water, without any tea, caffeine, or other kinds of drinks, but it is worth it. I have recommended this book to everyone I know and have taken it to my doctor to read. There are lots of testimonials in this book from doctors and clinics all around the country who have had the same excellent results using the recommendations in this book.
