The prevention of CF has been accomplished in pet, farm and laboratory animals by the veterinary profession by assuring adequate levels of selenium and essential fatty acid nutriture to the preconception, pregnant and nursing mother. This is not as easy as it sounds because of malabsorption problems (Le., celiac diseases and Crohn's Disease) in a percentage of women! All things being normal a supplementation of 200 mcg selenium per day and 5 gm of flaxseed oil t.i.d. would be adequate to prevent CF. Treatment of CF is very basic - treat the infant as early as possible with selenium 1Mat 10-25 mcg per day. Plant derived colloidal minerals may be used orally thereafter. Provide 5 gm of flaxseed oil orally t.i.d. Most importantly YOU MUST DETERMINE IF THE INFANT IS ALLERGIC TO WHEAT, COW'S MILK OR SOY!!! If you do not correct the malabsorption problem, treatment will only be minimally effective. In the case of older CF patients, IV essential fatty acids and 1M selenium provide excellent management leading to a normal life expectancy of 75 years!
