Differences between Lactose Intolerance and Dairy Allergy
Understanding Lactose Intolerance and Dairy Allergy
Lactose intolerance and dairy allergy are two distinct conditions that affect a significant portion of the global population.
Lactose intolerance, a digestive disorder, is a common condition affecting approximately half of the world's population [1]. It is caused by a deficiency of the enzyme lactase, which is required to break down lactose, the sugar found in milk. This deficiency leads to gastrointestinal symptoms such as bloating, diarrhea, gas, and abdominal pain [5][4].
On the other hand, dairy allergy is an immune system reaction to milk proteins such as casein or whey. This condition, more prevalent in infants and young children, can cause symptoms ranging from hives and digestive issues to potentially life-threatening anaphylaxis [3][2][4].
| Aspect | Lactose Intolerance | Dairy Allergy | |------------------------|--------------------------------------------|------------------------------------------| | Cause | Lactase enzyme deficiency | Immune reaction to milk proteins (IgE or non-IgE mediated) | | Mechanism | Inability to digest lactose (not immune) | Immune system activation and inflammation | | Symptoms | Bloating, gas, diarrhea, abdominal pain | Rash, hives, swelling, respiratory problems, anaphylaxis | | Component involved | Lactose (milk sugar) | Milk proteins (casein, whey) | | Onset | After lactose consumption, digestive symptoms only | Immediate or delayed allergic symptoms, involving immune cells and mediators like histamine |
A hydrogen breath test or a blood sugar test can be used to diagnose lactose intolerance, while a person's symptoms may suggest dairy allergy if they subside after avoiding dairy products. Treatment for lactose intolerance often involves dietary modification, lactase supplementation, or addressing an underlying condition in people with secondary lactase deficiency. Lactase nonpersistence, a common cause of lactose intolerance, occurs when the intestine produces less lactase after infancy.
Lactose intolerance is not an allergy because it does not involve the immune system. Instead, it is an inability to digest lactose due to a lack of the enzyme lactase. Lactose is a sugar that naturally occurs in milk and dairy products.
Dairy allergy can be an IgE-mediated or non-IgE-mediated reaction. People with dairy allergy should avoid consuming milk, cream, butter, whey, yogurt, cheese, some bread and baked goods, processed foods, and processed meats to manage their condition.
It is essential to consult a healthcare professional before making any dietary changes or using lactase supplements, especially for young children or pregnant individuals.
[1] Estimates suggest that roughly of the world's population experience lactose malabsorption. [2] Dairy allergy is the most common food allergy in infants and young children. [3] IgE-mediated dairy allergy reactions occur immediately. [4] The main difference between lactose intolerance and dairy allergy is that one is an allergy and the other is an intolerance. An immune reaction causes dairy allergy, and a lack of the enzyme lactase causes lactose intolerance. [5] Lactose intolerance is caused by a lack of the enzyme lactase. [4] Non-IgE-mediated dairy allergy reactions usually cause gastrointestinal symptoms such as vomiting, bloating, and diarrhea. [5] Lactase supplements can help people with lactose intolerance to digest lactose by breaking it down, often in the form of tablets or drops added to milk.

- Scientific research continues to enhance our understanding of medical conditions like lactose intolerance and dairy allergy.
- The science of nutrition plays a critical role in managing these conditions.
- Nutrition affects our immune system, and a balanced diet can improve overall health and wellness.
- Health and wellness encompasses various aspects, including fitness and exercise, mental health, skin care, and more.
- Fitness and exercise contribute to maintaining a healthy body.
- Mental health is essential for overall well-being and can be supported through therapies and treatments.
- Skin care is vital for maintaining healthy, glowing skin.
- Autoimmune disorders, such as rheumatoid arthritis and lupus, affect the immune system.
- Chronic diseases like cancer, respiratory conditions, and digestive health conditions can be managed with proper care.
- CBD, a compound found in cannabis, may be beneficial in managing certain neurological disorders and skin conditions.
- Adopting a healthy lifestyle includes making conscious choices about food, cooking, lifestyle, and education.
- Learning about health-related topics, such as food allergies, cooking, and lifestyle, promotes personal growth and productivity.
