A person who is lactose intolerant does not produce a sufficient amount of lactase, the enzyme used to break down the sugar commonly found in cow's milk -- lactose. To keep from triggering symptoms, people with this condition are advised to avoid foods and beverages containing lactose. Dietary alternatives to these products include soy milk, a lactose- and dairy-free milk substitute made from soybeans. If you have lactose intolerance, talk with your doctor before modifying your diet to include soy milk.
Function
Lactose intolerance produces similar symptoms to that of a milk allergy, but the two are very different conditions. A milk allergy is an overreaction of the immune system and is not directly connected to the digestive tract, like lactose intolerance is. Lactose intolerance is both a hereditary condition and a normal process of aging. MedlinePlus states that everyone has a certain level of lactose intolerance, but only those with symptoms are considered intolerant.
Common symptoms of lactose intolerance are diarrhea, abdominal cramps, nausea, weight loss, malnutrition, gas, floating stool, bloating and foul-smelling stool. These digestive-tract symptoms very rarely affect other parts of the body.
Soy Milk
Soy milk is made from cooked soybeans that are pressed and mixed with water, sugar and other additives. It can be used in cooking the same way cow's milk is used, without changing the texture or taste of food. Soy milk is cholesterol-free, low in fat, low in sodium and high in protein. It comes in plain, vanilla or chocolate flavors and does not taste like cow's milk.
Significance
Soy milk is an alternative to dairy and other lactose-containing products. For infants who are allergic or intolerant of milk formulas, soy-based formulas are used for feeding. Most soy milk beverages are fortified with calcium and vitamin D to give them the same nutrients as regular milk.
Managing Symptoms
Lactose intolerance has no cure, but the symptoms are manageable. Avoiding the consumption of products containing lactose is the best way to prevent symptoms. Your doctor also may recommend certain medications to help the body process lactose. For instance, lactase enzyme supplements may aid the body in digesting the sugar.
Considerations
Soy milk is intended to be used in moderation. According to Mercola.com, too much soy consumption may cause health problems. Some argue it is not a good alternative for young boys to drink soy milk because soy contains estrogen-like compounds that can affect their development. Critics also say that soy milk and other soy products may promote certain forms of cancer. Talk with your doctor if you have any concerns about using soy milk.
