The range of milk on the market is quite extensive…..you’ve seen the ad with the lady that reels off a list of about 20 different milks.
A question I quite often get asked is ‘what’s the difference between normal milk and A2 milk’.
Here’s the deal with A1 v A2. Cows produce either A1 beta-casein proteins or A2 beta-casein proteins and some produce both. Jersey cows predominantly produce the A2 proteins whereas Holstein cows produce A1 proteins, and these are the most common cows in Australian dairy herds.
Some health studies suggest the milk A1 protein can lead to inflammation and type 1 diabetes. Casein intolerance can produce symptoms such as gastrointestinal distress, chronic runny nose, eczema, frequent ear infections, and trouble breathing. Some people have reported an improvement of symptoms once changing to a milk with A2 casein protein.
If you are lactose intolerance though, a milk with A2 protein will not help your symptoms in anyway, it still contains the same amount of lactose as an A1 milk.
Lactose intolerance can produce symptoms such as bloating, diarrhoea and abdominal pain.
An allergy test can help determine if a person has a diary milk intolerance but it’s actually really hard to determine if a person has a casein or lactose intolerance, its best to do an elimination diet and then reintroduce previous problems foods to see if they produce the same symptoms.
