Low Lactose Diet

Low Lactose Diet

The low lactose diet is designed to decrease symptoms of bloating, gas, abdominal cramping, nausea and diarrhea resulting from incomplete digestion of milk sugar, or "lactose." The goal is eat dairy products for healthy bones and teeth without uncomfortable symptoms.

When to Follow a Low-Lactose Diet

The diet is used for children with lactose intolerance or lactase deficiency. Symptoms of lactose intolerance may develop 30 minutes to 2 hours after eating lactose-containing foods and drinks. Lactose intolerance varies; if an individual has no symptoms, then no restrictions are needed. Following the lactose controlled diet will help control symptoms.


The diet restricts foods containing lactose, or milk sugar, found mostly in dairy products. Most persons with lactase deficiency can tolerate small amounts of lactose without a problem. Children with severe lactase deficiency may need to avoid even smaller sources of lactose.

Food label terms that may indicate lactose in the product include milk, milk solids, whey, lactose, curds, margarine, skim milk, powder, sweet or sour cream, buttermilk, and malted milk.

Dairy products can be consumed based on individual tolerance- whether or not you develop symptoms depends on the individual and the amount of dairy product that you consume.

Some dairy products are better tolerated than others.

  • Whole milk may be better tolerated than lower fat milks.
  • Cocoa and chocolate milk may be better tolerated than plain milk
  • Yogurt and aged cheeses are better tolerated, due to lower lactose content.
  • Frozen yogurt and ice cream are often tolerated because of their solid consistency and their fat content

Lactose reduced dairy products such as "Lact-Aid" treated milk can be found in most supermarkets, and come with varying degrees of lactose reduction (e.g., 70 to 100% treated). Patients may choose to treat milk with enzyme products drops or tablets; brands include "Dairy Ease" and "Lact-Aid".
