I went to school in Chicago. After taking the supplement the next time she ate pizza, she was symptom free. Symptoms include bloating, painful cramps, and diarrhea, which regularly appear within 15 to 30 minutes after eating dairy products. It takes a little experimenting. Methodical trial and error can let people know just how much and which kinds of dairy products they can tolerate.
Some people can tolerate a glass of milk as long as they drink it with a meal.
Those who cannot tolerate any lactose at all, Pozo Fileti adds, should supplement their diet with calcium and vitamin D and look for alternative sources of calcium. Dairy Still Possible Pozo Fileti also recommends lactase supplements, which allow people to continue to eat dairy products. Products to which lactase has already been added, such as lactase-enriched milk, make it even easier. For Janotta, the supplements mean she can eat pizza and her other favorite dairy foods. Yogurt and aged cheeses are also good choices because the bacteria in these dairy foods have already broken down the lactose.
