Almost every adult is intolerant to lactose to some extent, but only people with distinctive symptoms are diagnosed. One approach to preventing symptoms is to use alternatives to dairy, such as soy products. Soy products are considered safe for people with lactose intolerance because they are dairy and lactose-free. Soy products are derived from soy beans, a legume that is processed with water, sugar and other ingredients to make soy milk.
Background
Newborns produce a lot of lactase, the enzyme needed to digest lactose, but during adolescence the body stops producing as much lactase, which can lead to lactose intolerance. The digestive tract produces enzymes that break down certain sugars and proteins into simpler forms so the body can absorb them easily. If you're lactose intolerant, your intestines don't create enough lactase to properly digest the milk sugar. This results in the inability to absorb the sugar into the body, causing inflammation, swelling and irritation in the digestive tract.
Effects
Most symptoms occur within a half hour and up to two hours after you ingest dairy products. Not everyone is intolerant to the same degree, so you may be able to drink a small amount of milk without any issues, while someone else cannot consume any dairy. The more dairy you consume, the worse your symptoms will get. Common symptoms include gas, bloating, diarrhea, nausea and cramping. In extreme cases, symptoms may lead to dehydration, malnutrition and weight loss. Discuss your symptoms with your doctor.
Soy Alternatives
One of the most common preventative measures is to avoid the consumption of all diary products. Soy products, such as soy milk, soy-based cheeses and soy-based yogurts, are manufactured to replace milk products. These products are lactose-free but may lack essential calcium and vitamin D needed by your body. Some soy products are fortified with calcium and vitamin D, but your doctor may recommend using a dietary supplement to make sure you are receiving the needed vitamins and nutrients that you would commonly receive from dairy.
Consideration
If you are allergic or intolerant to soy, you can find other ways to treat your condition. Lactase supplements are available in pill or drop form. Taking the supplement whenever you ingest dairy products will help prevent symptoms. Some dairy products are available in a lactose-free version that you can safely use.
