Life with lactose intolerance: Food shouldn't hurt
April 10, 03

If abdominal cramps, bloating, and quick trips to the loo frequently punctuate your days, you may not need to look much farther for the cause than your glass of milk.

That's especially true if you are black, Asian, Hispanic, Native American, or of Mediterranean descent. In other words, just about anyone who isn’t of Northern European or Western European heritage.

In fact, 50 million Americans are lactose intolerant, as are three quarters of all adults worldwide. That figure for the U.S. is going to grow, considering that Census data tell us that our nonwhite minority is going to be close to a majority by the year 2050.

Lactose intolerance in adults is a normal condition in which the body is unable to adequately break down the milk sugar lactose, resulting in a range of symptoms that may include nausea, gas, diarrhea, bloating, and abdominal cramps.

Like other mammals, human babies and young children produce the enzyme lactase to help break down the sugar found in mother’s milk, helping it to be digested fully so that the body can absorb it. As mammals age, though, they outgrow the need for mother’s milk and move on to solid food. Most people produce less and less lactase until many eventually produce none or very little.

Think about it: How many grown cows have you seen drinking milk from their mothers? Likewise, after weaning, humans no longer require nor do most tolerate human milk, never mind milk from another species.

The exception is people from northern and northwestern Europe – the Irish, British, Scandinavians, and others. For them, a genetic mutation is thought to have led to the ability to produce lactase throughout adulthood, enabling them to eat large amounts of milk and milk products without suffering symptoms of indigestion.

If you think you may be lactose intolerant, your doctor can conduct one or more tests to confirm or rule out your suspicion.

However, lactose intolerance isn’t necessarily all or nothing. Some people who are lactose intolerant can digest small amounts of dairy foods without suffering symptoms. It may be a matter of trial and error to determine your limits.

To minimize symptoms:

• Spread it out. If you’re eating cheese at a meal, leave the milk for later in the day.

• Limit portions. Use less milk in your cereal, and cut in half the amount of cheese you use in sandwiches and casseroles. Big bonus: You’ll slash your saturated fat intake, too.

• Know where to look. Individuals who are particularly sensitive may need to avoid the small amounts of lactose in such foods as cookies and milk chocolate. Read food labels. Ingredients such as whey, nonfat milk solids, margarine, sour cream, buttermilk, and others are used to make baked goods and other products and are enough to give some people problems.

• Experiment. Yogurt with active cultures and hard cheeses such as sharp cheddar, for example, contain less lactose than milk or cottage cheese.

• Substitute. Instead of regular dairy products, buy reduced-lactose or lactose-free products, such as Lact-Aid milk. Soymilk and rice milk are widely available in supermarkets and natural foods stores now, and many brands are fortified with calcium and vitamins A and D. They can be used cup for cup to replace cows' milk in recipes, too.

• Try enzyme tablets. Pharmacies carry products such as Lact-Aid or Dairy Ease tablets and drops, which can be used before meals containing dairy products. Results vary from person to person.

"So if I choose to reduce my dairy intake, what about calcium?" you ask.

Complicated topic and answer. I promise to address this in a future column.

For now, however, suffice it to say that many, many foods contain ample amounts of calcium. For starters, calcium-fortified orange juice and soymilk are similar to cow’s milk in calcium content.

Beans and greens are also rich sources, and that’s bringing us perilously close to the recommendations for an overall healthy diet. It really all makes sense.

The bottom line: Your food shouldn’t make you hurt, and it shouldn’t make you sick. If it does, your body is trying to tell you something and you should consider the alternatives. There are some good ones.
