What Is A2 Ghee and Is It Worth It?
Share
You have probably started seeing A2 milk in supermarkets, and now A2 ghee is appearing on shelves. The marketing around it can feel technical and a little baffling. Here is what it actually means, stripped of the jargon.
What Does A2 Mean?
All cow's milk contains a protein called beta-casein. But there are two versions of this protein: A1 and A2. Most commercial dairy cows in the UK and Europe produce milk that is predominantly A1. Older British breeds, including Jersey, Guernsey and some Highland cattle, naturally produce milk that is predominantly A2. This is not a modern invention or a genetic modification. It reflects a difference in cattle breeds that existed long before industrial farming.
A1 vs A2: What's Different in Practice?
When A1 beta-casein is digested, it releases a peptide called BCM-7 (beta-casomorphin-7). Research suggests that BCM-7 can cause digestive discomfort in some people, including bloating, cramping and loose stools. These symptoms are often attributed to lactose intolerance, but in some cases the problem is actually A1 beta-casein rather than lactose. A2 beta-casein does not produce BCM-7 in the same way.
This is why many people who think they are lactose intolerant find that some dairy products cause symptoms while others do not. It may not be about lactose at all.
What Is A2 Ghee?
A2 ghee is ghee made from the butter of A2 cows. When the butter is clarified to make ghee, the milk solids (including most of the lactose and casein) are removed. What remains is pure fat. An A2 ghee therefore combines two things that dairy-sensitive people often find helpful: the naturally gentler A2 protein structure in the source milk, and the removal of most dairy proteins during the clarification process.
Is It Worth Paying More For?
For most people who have no particular sensitivity to conventional dairy, regular grass-fed ghee is excellent and the A2 distinction is probably not necessary. The extra cost reflects the smaller scale of A2 dairy farming and the rarer breeds of cattle involved.
For people who notice that certain dairy products upset their digestion, or who have been told they are lactose intolerant but find that some cheeses and foods made with butter are fine while others are not, A2 ghee is genuinely worth trying. The experience of many people who have made the switch is that it sits more comfortably.
Who Benefits Most?
People with mild dairy sensitivity, those following an Ayurvedic approach to eating (traditional Indian ghee was made from indigenous A2 breeds), and those who simply want the cleanest, most traditional version of ghee are the most likely to find the A2 distinction meaningful.
