Try as I might there are some clients who either don't like or test well to alternative milks or are determined to have their usual cow's milk come what may, especially in their cup of tea. Now there is a much better option I can recommend to these clients - A2 milk.
You may have noticed A2 milk in the supermarket and wondered what it is - it has been available for a number of months now. The cows in the herds that produce A2 milk have been screened to ensure that they provide milk containing the A2 protein only - this is a protein it is believed that all domesticated cows once produced. However, a genetic mutation and modern farming practices have resulted in a significant proportion of cows now producing milk containing the A1 protein which can trigger symptoms often associated with lactose intolerance. Typical symptoms may include a build up of mucus, constipation, diarrhea, eczema, sickness, stomach pain, bloating, skin irritations and acne and spots. It is estimated that around 25% of the UK population may have problems digesting the A1 protein.
A double blind, randomised 8-week cross-over study in 2014 supported that hypothesis that the A1 protein can cause gastro-intestinal inflammation in susceptible people - this inflammation is then is a trigger for lactose intolerance. Other symptoms associated with the A1 protein in the study included a longer gut transit time and impaired cognitive function.
A2 milk is not appropriate for milk allergy sufferers. People who are already drinking cows milk can just subsititute A2 milk in its place. Lactose intolerance sufferers or people who have given up milk as they feel it does not agree with them are advised to try a small amount of A2 milk, eg a teaspoon, and monitor symptoms, gradually increasing the intake slowly over the course of a couple of weeks. Alternatively come along for a kinesiology session and see which milk you are best suited to!
