Lactose Intolerance

Overview

If you have lactose intolerance it means that you cannot digest lactose, which is the sugar that is found in milk. This happens when your body does not produce lactase, an enzyme that is needed to break down the lactose or milk sugar.

How Do You Know If You Have Lactose Intolerance?

You may be lactose intolerant if you develop stomach symptoms within a few minutes to a couple of hours after consuming milk or other foods made with milk. The symptoms may be quite mild in some people, moderate in others and severe in the worse cases.

Symptoms of Lactose Intolerance

If you have any of the following symptoms after consuming milk or milk products, you may have lactose intolerance:

• Gas
• Bloating
• Stomach pain
• Diarrhea
• Nausea

What Should You Do If You Have Lactose Intolerance?
If your symptoms are mild, you might be able to consume a small amount of milk or milk product. Some people who are lactose intolerant are able to consume cheeses and yogurt without experiencing any serious symptoms, even if they cannot tolerate regular milk. You should pay attention to the signals in your own body and avoid those things that trigger a reaction. Always consult with your doctor to rule out any more serious medical condition.

Some supermarkets carry lactose-free or lactose-reduced milk. You might consider trying one of these if you are concerned about getting enough calcium. You can also get calcium from soy milk and other non-milk foods that have been fortified with calcium. 

Lactase enzyme, sold as an over-the-counter product is another option. This enzyme helps to digest the sugar in milk, making it easier for you to consume milk and milk products without the symptoms of lactose intolerance.

What Are Some Non-Dairy Foods That Contain a Good Bit of Calcium?

There are not many foods that provide calcium in amounts close to what you would get from milk, cheese, yogurt or other dairy products. However, there are a few foods that might help to fill the gap.

Here is a short list:

Rhubarb, frozen ....................... 348 mg per cup, cooked

Sardines with bone .................. 325 mg per 3 oz serving

Spinach, frozen ........................ 291 mg per cup, cooked

Salmon, canned, with bone ...... 181 mg per 3 oz serving

Soy milk, unfortified .................. 61 mg per cup

Orange ....................................... 52 mg per medium orange

Broccoli, raw ............................. 41 mg per cup

Pinto beans, cooked ................... 80 mg per cup

In comparison, milk would provide between 250 and 285 mg calcium per cup; Swiss cheese 224 mg per oz; and cottage cheese 87 mg per half-cup.

Summary

If you have lactose intolerance, talk to a registered dietitian to find ways of incorporating more calcium-rich foods in your diet. She can help you to get the calcium you from dairy foods that you can tolerate along with other calcium-rich, non-dairy foods while eliminating those dairy foods that you cannot tolerate.
