How to Reintroduce Dairy into your Diet

 Posted on August 15, 2017

Did you know??

Millions of Americans have diagnosed themselves with lactose intolerance?

It’s important we tackle this issue more in depth and discuss what may actually be the cause of post dairy digestive discomfort post dairy digestive discomfort.

Enter — the A1 beta casein protein.

The difference in proteins

Cows naturally produce A1 beta casein protein, A2 beta casein protein, or a blend of the beta caseins in their milk supply. Through a simple DNA test, farmers can identify which cows produce either the A1, the A2, or a mix of both.

What’s interesting is that scientists have found that A1 beta casein can cause an inflammatory response and other reactions in the body in certain individuals, many who have self-diagnosed lactose intolerance. This often results in symptoms that mimic lactose intolerance, such as bloating, constipation, diarrhea, etc. after drinking cows’ milk.

The science

In a recent study published in April 2016, 45 Chinese subjects with milk sensitivity participated in a double-blind, randomized, crossover trial. Participants drank both conventional milk (with A1 and A2 proteins) and a2 Milk® (A1 protein-free). Researchers confirmed that individuals could tolerate A1 protein free milk without any digestive discomfort, lending support to the notion that A1 protein may likely be the cause of post dairy digestive discomfort.

Currently, studies are being done here in the US to replicate these results in a representative American population.  In the meantime, a2 Milk® may provide an option for many people to return to milk. Just check out their testimonials here!

Reintroducing Dairy

As with any reintroduction, a2 Milk® should be done modestly. Bonnie Johnson, The a2 Milk Company’s™ registered dietitian nutritionist, recommends starting small, such as a couple of tablespoons in coffee or tea, or a small amount on your cereal.  There’s also a great list here with sample suggestions on how to add a2 Milk® back into a diet.  By adding dairy back into your diet in the comfort of your own home, you’ll be able to monitor and document the symptoms, or lack thereof!
