Milk has become a hotly debated health topic. On one side, some argue that all cow’s milk is inflammatory and promote plant-based alternatives like almond, oat, and coconut milk. On the other side, some believe that while regular milk may be inflammatory for some, choosing the right quality—such as grass-fed, low-temp pasteurized, non-homogenized, or raw milk, and the right type of cow, like Jersey cows, and the A2 protein—can make a significant difference, offering high nutritional value. Before making a decision, it’s important to understand the various types of milk, their health benefits, and potential risks. In this article, I’ll explore these options, with a primary focus on the health benefits of A2 milk, helping you decide whether it’s the right choice for you and your family.

What is the Difference in Regular Milk and A2 Milk?

Most of the regular cow’s milk you find at the grocery store contains primarily A1 beta-casein protein. Beta-casein proteins make up about 80% of the protein content in milk, with the remaining 20% being whey proteins. These beta-casein proteins are crucial for providing stability, structure to milk curds, and aiding in muscle repair and growth. There are two main types of beta-casein proteins in milk: A1 and A2, which differ by just one amino acid. Certain cow breeds, such as Holstein-Friesians, produce milk with a higher concentration of A1 beta-casein, while breeds like Jersey cows produce milk rich in A2 beta-casein. A2 was the original protein found in milk and is also present in human and sheep’s milk. Over time, a genetic mutation led to the evolution of A1 beta-casein, making milk with higher A1 protein content more common. Most commercially farmed dairy cows produce milk containing a mix of both A1 and A2 proteins, which is what we typically find in regular milk and dairy products.

Possible Negative Health Affects of A1 Milk Consumption

Milk that contains the A1 protein has been shown to cause digestive issues like bloating and abdominal pain. Because of the difference in the amino acid, the body breaks apart the A1 beta-casein protein creating a peptide called (beta-casein morphin). This peptide has been shown to be make digestion slower, causing digestive issues. Other studies are even showing a link between A1 milk consumption and heart disease, immune suppression and diabetes. In children, studies suggest that since the A1 protein can cause inflammation it may be linked to an increased risk of inflammatory issues in children. Some of these health concerns include: acne, asthma, eczema, ear infections and allergies.

Possible Digestive Health Benefits of A2 Milk

Unlike the A1 beta-casein protein, numerous studies suggest that A2 milk is easier to digest and may offer gut health benefits. Research indicates that individuals who consume A2 milk show fewer inflammatory markers compared to those who drink A1, suggesting a reduced risk of gut inflammation. Additionally, A2 dairy can be better tolerated by some people with lactose intolerance, as they may have an intolerance to the A1 protein rather than lactose itself. As a result, these individuals can enjoy A2 milk without experiencing digestive issues.

Essential Nutrients Found in A2 Milk

A2 milk contains a variety of essential nutrients that are important for overall health. It is rich in high-quality proteins, including A2 beta-casein. A2 milk also provides a good source of calcium, which is crucial for strong bones and teeth, as well as easily absorbable vitamin D, which helps the body absorb calcium. Additionally, it contains essential vitamins like B12, riboflavin, and minerals like potassium and magnesium, all of which contribute to energy production, muscle function, and maintaining a healthy immune system. With these nutrients, A2 milk offers a nutrient-dense option for those looking to support their overall well-being.

Ways to Consume A2 Dairy Products and Brands

The brand of A2 milk I consume is local and raw. I choose raw milk for reasons beyond the A1/A2 beta-casein proteins but there are some good A2 brands availabe at the grocery store. Alexandre Family Farm offers grass-fed A2 milk products from their regenerative farm. As a holistic nutritionist I love to purchase their kefir and yogurt. I like Bellwether Farms A2 yogurt, you can find it at Costco. A few ways you can consume A2 dairy include:

• yogurt and fruit
• kefir and fruit
• milk in a healthy cereal
• milk in homemade hot chocolate

A2 Raw Milk

A2 raw milk is my milk of choice. I developed eczema when I was drinking milk that contained the A1 beta-casein protein, so I always stick with A2. I choose raw milk, from a trusted local source, because raw milk retains more nutrients because it isn’t heated up during pasteurization. Pasteurization, the process of heating milk to kill bacteria will also kill good bacteria and some of the essential nutrients found in milk. If you try A2 milk from the grocery store and are still having digestive issues, A2 raw milk is another option to try for easier digestion.
