In reference of World Milk Day that was celebrated June 1. We shall be talking about Milk allergies vs Lactose Intolerance in today’s blog post
What is a milk allergy?
A milk allergy is one of the most common allergies found in children and infants. Upon consumption of milk, the immune system recognizes the substance as a foreign invader and an allergic response is triggered. In mild cases, an allergic reaction can cause itching, hives, swelling, etc., however, in severe cases it can lead to anaphylaxis which results in wheezing, trouble breathing and loss of consciousness. Milk allergy usually refers only to cow’s milk, though you may also be allergic to other types of milk, including soy. Milk allergy is the most common food allergy in children, and it can develop at any age. Many children outgrow milk allergies by age 5.Symptoms may include; stomach pain, nausea, diarrhea, skin rash, swelling of the lips or throat and trouble breathing.
What is lactose intolerance?
Lactose intolerance is caused by not having enough of the enzyme lactase, which is needed to break down lactose, the sugar found in milk and other dairy products. Since lactose cannot be broken down, it builds up in the digestive system and this undigested lactose then moves into your colon, where it’s broken down by bacteria and leads to abdominal gas and bloating. Lactose intolerance is usually common in adults and its symptoms typically occur within 30 minutes- 2 hours following lactose consumption. Symptoms may include; stomach pain, gas and bloating, nausea and diarrhea.
Lactose intolerance is least common among Americans of European descent. Most European cultures have utilized milk in their diet for hundreds of years that people have built up a tolerance to the product. However, African Americans, Asian Americans and Hispanics originate from cultures where milk is not as commonly used in foods, therefore lactose intolerance is much more prevalent.
Difference between Milk Allergy and Lactose Intolerance
Lactose intolerance and milk allergy sound a lot alike and have some similar symptoms so many people think they’re the same thing. But, how they’re caused (and how they affect your body) are very different. The main difference between lactose intolerance and milk allergies is that lactose intolerances are related to the digestive system while milk allergy involves the immune system.
Lactose intolerance is not a life threatening condition and will not cause anaphylaxis shock (rash, low pulse, and shock), which occurs as a severe allergic reaction to venom, food, or medication.
Can You Eat Dairy With Lactose Intolerance or Milk Allergy?
For both of these conditions, you’ll need to avoid or limit most dairy products. But it is important to make sure you are getting enough calcium.
Lactose intolerance is easily managed, mostly by limiting the amount of dairy food and drink you consume. You can also try lactose-reduced ice cream and milk, or take lactase enzyme supplements when you eat dairy products to help your body digest lactose.
If you have milk allergy, you’ll need to avoid all dairy foods and other foods that contain dairy products. Staying safe means reading food labels to see if milk or ingredients containing milk are included. Milk proteins are found in many foods you wouldn’t expect. Some canned tuna, energy drinks and even chewing gum contain them. And don’t eat lactose-reduced foods if you have a milk allergy. They still contain the milk proteins that can cause allergic reactions. Some of these milk proteins are casein, whey, lactulose, lactalbumin, and ghee.
If you or your child has symptoms that may be due to milk allergy or lactose intolerance, talk with a doctor. He or she can diagnose the problem and refer you to a Nutritionist/ Registered Dietitian who will advise you on how best to avoid dairy while maintaining good nutrition, which is important no matter how young or old you are.
So, I hope we were all able to learn something from today. Kindly share with your family and friends as they could also learn as well.
