Allergies and intolerances

Foods can upset people for many reasons. If you break out in hives, or wheeze or vomit after drinking milk, you probably have a milk allergy. But if you feel bloated or get an upset stomach, you probably have lactose intolerance.

Milk (along with egg and wheat) allergies are the most common allergies in children. Many children tend to grow out of them by the time they're aged four or five.

If you follow a vegan diet or you're allergic to cows' milk or just don't like the taste, there are several alternatives you can try.

Soy milk

Soy milk has less saturated fat than regular milk, is a good source of protein and is lactose-free. Soy also contains isoflavones, a type of plant oestrogen. Isoflavones are thought to be responsible for soy's positive effects - such as reducing blood cholesterol, protecting against heart disease, and reducing the risk of some cancers.

The evidence for these benefits is mixed and some groups are concerned that soy products pose health risks.

Soy is naturally low in calcium so make sure you choose a calcium-fortified product.

Rice milk

Rice milk is made from rice, water and vegetable oil. It's low in fat and saturated fat and is lactose free. But it isn't a good source of calcium, protein or some of the other nutrients in dairy products.

In 2006, Food Standards Australia New Zealand issued a warning that rice and other cereal-based beverages aren't a suitable milk substitute for children aged under five. These drinks are now required to carry this advisory statement.

If you use rice milk as a replacement for dairy milk, make sure it's fortified with calcium and don't rely on it as a good source of protein and vitamin D.
