Thanks for posting your query at HealthCareMagic. Since you have mentioned, let me mention that your son has lactose intolerance and not milk allergy which are two different ailments. As of now, Lactase enzyme supplements will be able to provide him relief. You may also give him some drotin (drotaverine) tablets to relieve the cramps. The degree of intolerance differs with each person. The best way to assess your tolerance is first to get all lactose out of your system by avoiding all lactose-containing foods for three to four weeks. Then start with very small quantities of milk or cheese. Monitor your symptoms to see how much or how little dairy food you can handle without experiencing discomfort. Once you know your limits, management becomes a little easier. Cocoa powder. Studies indicate that cocoa powder and sugar, or chocolate powders, may help the body digest lactose by slowing the rate at which the stomach empties. The slower the emptying process, the less lactose that enters your system at once. That means fewer symptoms. The calcium in chocolate milk is just as well absorbed as that in regular milk, and you may tolerate flavored milk better than plain. Also note, nondairy foods that contain calcium, include: * Broccoli, okra, kale, collards, and turnip greens. * Canned sardines, tuna, and salmon. * Calcium-fortified juices and cereals. * Calcium-fortified soy products such as soy milk, tofu, and soybeans. * Almonds. I hope that helps. Feel free to revert back in case of further queries.
