How Do I Know if I'm Sensitive to Dairy?

There are some general signs and symptoms. The following are dairy sensitivity symptoms to be on the lookout for...

What's The Difference Between Dairy Sensitivity & Lactose Intolerance?

Lactose Intolerance

Lactose intolerance unfolds when you don't have enough of the enzyme lactase to break down lactose, a type of sugar found in dairy products. 

Lactose Intolerance

Undigested lactose ends up being food for the resident gut microbes. As they ferment the lactose, they create gases that cause bloating, flatulence, pain, and sometimes diarrhea.

Lactase Deficiiency

Lactase deficiency affects up to 15% of people with northern European ancestry, up to 80 percent of black and Latino individuals, and up to 100% of American Indians and Asians.

Dairy Sensitivity (Milk Allergy)

Dairy Sensitivity

Dairy sensitivity is an immune reaction to dairy proteins. When a person with dairy sensitivity eats dairy, their body produces antibodies to fight the dairy proteins.

Dairy Sensitivity

Dairy sensitivity symptoms usually appear within minutes to hours after consuming dairy. In severe cases, it can cause anaphylaxis, a life-threatening reaction requiring immediate medical attention. 

Milk Allergy

The two main dairy or milk proteins that people are allergic to are casein and whey, and you can be allergic to one or both of these proteins.

Seek Medical Advice

If you're unsure whether you have a dairy sensitivity, lactose intolerance, or milk allergy, it's important to see a doctor.

Dairy Allergy Tests

There is no standard test for cow's milk allergy. As a result, the diagnosis isn't simple, and based on the patient's history of symptoms and physical examination.

Dairy Allergy Tests

There are a few different tests that can be used to diagnose lactose intolerance. These include: - Hydrogen breath test - Stool acidity test - Exclusion diet - Lactose tolerance test

What about milk from other animals?

The proteins in cow's milk are comparable to those found in goat, sheep, and other ruminant milk. So, if you're allergic to cow's milk, it's likely you will also have a negative response to other milks.

How Can You Safeguard Yourself?

1. Read food labels carefully. Look for dairy ingredients like whey, casein, and lactose. 2. When in doubt, ask the waiter or chef about the ingredients in a dish. 3. Bring your own dairy-free food to parties and potlucks. 4. Be aware that dairy can be hidden in unexpected places, like medications, vitamins, and supplements. Always read the labels on these products.
