People talk of having an allergy to cow s milk, but such allergies are in fact quite rare. People are normally referring to an intolerance of cow s milk, through the body s reaction to lactose, the natural sugar of milk. It is a double sugar that has to be divided into two separate sugars for the body to be able to use them. This division usually takes place in the small intestine, mediated by an enzyme known as lactase. After birth and during infancy, most people produce enough lactase to digest the milk s lactose. It is at a later age that some adults do not secrete enough lactase, particularly when they have stopped drinking milk regularly. In such cases, the undigested lactose passes into the large intestine, where it is fermented by bacteria. This intolerance is quite frequent in adults in Asia, the Middle East, Africa and South America; it is rarer in Europe and North America. People suffering from this ailment can nonetheless consume milk in small amounts, as well as unlimited amounts of butter, cheese and yoghurt as these products contain very little lactose. An alternative to cow s milk is soya milk, which is also a complementary foodstuff. The revised and expanded edition of the Agrodok 10 on Growing soya co-published by Agromisa andCTA will be featured in Spore 103.
