Cow's Milk: Pros and Cons
Occasionally, recommendations are made that children over
2 years old and adults should not drink cow's milk. The American
Academy of Pediatrics and the American Medical Association
strongly disagree with this position. Here are the reasons the
benefits of drinking cow's milk outweigh the risks.
The Benefits of Cow's Milk
Dairy products are an inexpensive source of protein. They are a
convenient source of calcium. In addition, they often taste good.
These benefits of milk haven't changed.
The Risks of Cow's Milk
- Bleeding from the intestines during infancy
The intestines of some babies may bleed if they drink cow's
milk during their first year of life. This slow leakage of
blood from the lining of the intestine can cause iron
deficiency anemia. For this reason, pediatricians no longer
recommend giving cow's milk to children during their first
year of life.
- Food allergies
About 1% of children are allergic to the protein in cow's
milk. When they eat or drink milk products, they may develop
hives, diarrhea, wheezing, or other allergic symptoms. These
children need to avoid cow's milk products.
- Lactose intolerance
Lactose is the sugar found in milk. Some children and many
adults have a condition called lactose intolerance and have
bloating and diarrhea when they eat or drink milk products.
You can prevent these symptoms by adding lactase drops to the
milk. (Lactase is an enzyme that helps people digest the sugar
in milk.)
- Heart disease
Children with strong family risk factors for early heart
attacks should avoid cow's milk products because of the high
amounts of cholesterol and saturated fat in whole milk. You
can reduce this risk by giving your child skim milk or 1% milk
after 2 years of age.
Precautions for Children Who Avoid Milk
Children and adults who need to avoid drinking milk or eating food
made from milk must supplement their diets with calcium. Children
who don't get enough calcium every day may develop rickets, which
leads to soft bones and short stature. They also have a greater
chance of fractures. Also, these children do not store enough
calcium to build strong bones and prevent osteoporosis during late
adulthood.
Several brands of calcium fortified juices, cereals, and soy foods
are now available. Although these foods make it easier to meet
daily calcium needs, it still can be hard to get enough without
dairy products. Ask your healthcare provider or dietitian if your
child should take a calcium supplement. They are available without
prescription in liquid, chewable, and tablet forms.
Calcium-fortified orange juice is also available and contains as
much calcium per ounce as milk products.
Recommendations
- During the first year of life children should either be
breast-fed or be given iron-fortified formula.
- Give whole cow's milk to children 12 to 24 months old.
- Children who don't like the taste of milk will often drink 3
servings a day if they are offered chocolate or strawberry
milk. Flavored milks do not have any nutritional drawbacks.
- After 2 years of age children should drink low-fat milk. If
they are overweight, they can drink skim milk.
Consuming milk products in moderation is not harmful.
