Arnie , the diffences between intolerance & allergies,well it can be very discreet in that with intolerance, the mere fact that your father comes from Western Samoa ,Nigeria.or India could render you intolerant to cows milk, for instance,where as someone whose parents are Swedish, or Irish ,for instance could drink gallons of the stuff without ill effects. I believe it is to do with chromasomes .We have a situation here in Australia where the native aboriginals are not only intolerant to milk, but alcohol affects them so badly it is a major problem here. all due to chromosomes. Allergies on the other hand are brought on by the bodies defences over reacting to the triggers& irritations that set them into action . As the immune system gets weaker, it becomes over sensitive & allergic with more & more triggers. Say for instance a person is allergic to tomatoes, & somehow gets talked into having a meal which consists of them. The chances are that person will no longer be able enjoy potatoes, capsicums,egg plants or any of the solanum family because of the body`s recogition that they are relatives to the tomato. If by chance there is a product that can lower that allergic reaction, & lower the inflamation caused by that reaction then we have less triggers,& we as I.B.S sufferers start to get away with more & more foods we were 'allergic' toduring that extra sensitive period. Where there is inflamation anywhere in the body there is sensitivity of some kind which can cause pain, itchiness, spasms, C, D, arthritis,gout,.I.B.S of course, & in the head, Migraines, headaches , neuralgia,sore eyes etc. Get rid of that inflamation, & the healing process begins. The Mangosteen fruit has been proven to do this naturally without the damage to the stomach walls that anti-inflamatory drugs are notorious for. By reduction of the inflamation & rebuilding the immune system, even the those who have an intolerance to dairy , for instance, will have less reaction and/or repair faster after their 'splurge' than those with low immunity.
