Milk and milk products are a major source of calcium and other nutrients. Calcium is essential for the growth and repair of bones at all ages. A shortage of calcium intake in children and adults may lead to fragile bones that can easily fracture later in life, a condition called osteoporosis. The amount of calcium a person needs to maintain good health varies by age.
Women who are pregnant or breastfeeding need between 1,000 and 1,300 mg of calcium daily. Getting enough calcium is important for people with lactose intolerance when the intake of milk and milk products is limited. Many foods can provide calcium and other nutrients the body needs. Non-milk products that are high in calcium include fish with soft bones such as salmon and sardines and dark green vegetables such as spinach.
Yogurt made with active and live bacterial cultures is a good source of calcium for many people with lactose intolerance. When this type of yogurt enters the intestine, the bacterial cultures convert lactose to lactic acid, so the yogurt may be well tolerated due to lower lactose content than yogurt without live cultures. Frozen yogurt does not contain bacterial cultures, so it may not be well-tolerated. Calcium is absorbed and used in the body only when enough vitamin D is present. Some people with lactose intolerance may not be getting enough vitamin D.
Vitamin D comes from food sources such as eggs, liver, and vitamin D-fortified milk and yogurt. Regular exposure to sunlight also helps the body naturally absorb vitamin D. Talking with a doctor or registered dietitian may be helpful in planning a balanced diet that provides an adequate amount of nutrients—including calcium and vitamin D—and minimizes discomfort. A health professional can determine whether calcium and other dietary supplements are needed.
