Let’s talk about Milk.

February 06, 2026  /  Charlotte Tiffany

Taking care of your health doesn’t have to mean drastic changes or strict rules. Often, it starts with paying attention to how your body responds—and being open to learning why.

Knowledge is one of the most supportive tools we have. When we understand what’s happening beneath our symptoms, we can make choices that work with our body instead of fighting it.

This is especially true for conditions that show up on the skin.

Skin issues like acne, eczema, rosacea, or unexplained rashes are often treated as surface-level problems. But for many people, the skin is simply reflecting something deeper—commonly linked to digestion, inflammation, or food sensitivities.

Milk is one example worth exploring.

Millions of people believe they’re lactose intolerant. They notice bloating, cramping, loose stools, or general discomfort after drinking milk and assume the issue is lactose—the natural sugar in milk.

Sometimes that’s true.

But sometimes, it isn’t.

For a portion of people, the reaction may be related not to the sugar in milk, but to one of its proteins—specifically a variation that many of us were never taught about.

The Milk Humans Originally Consumed

Historically, all mammals—including cows—produced milk containing a protein called A2 beta-casein.

This same protein structure is found in:

  • Human breast milk

  • Goat milk

  • Sheep milk

  • Buffalo milk

In fact, for most of human history, this was the only type of beta-casein humans consumed.

Thousands of years ago, during cattle domestication and selective breeding in parts of Europe, a natural genetic mutation occurred in some cows. One small change in the beta-casein protein led to a new variant, now called A1 beta-casein. Over generations, cows producing higher milk yields were favoured, and this A1 variant became widespread. Today, most conventional cow’s milk in Western countries contains A1 beta-casein—or a mix of A1 and A2.

The difference between A1 and A2 milk comes down to a single amino acid. That may sound insignificant, but digestion is highly sensitive to structure. When A1 beta-casein is digested, it can release a peptide called BCM-7 in some individuals. This compound has been shown to interact with receptors in the gut and may influence digestion, gut motility, and inflammatory responses.

A2 beta-casein does not produce this peptide during digestion.

For many people, this difference means nothing at all—they tolerate regular milk just fine.
For others, it may help explain why milk causes digestive discomfort, systemic inflammation, or even flare-ups in inflammatory skin conditions.

The gut and skin are deeply connected through the immune system and inflammatory pathways. When digestion is stressed or the gut lining becomes irritated, inflammatory signals can show up elsewhere in the body—including the skin.

This is why some people notice that dairy affects not just their stomach, but also:

  • Acne breakouts

  • Eczema flares

  • Redness or itchiness

  • Slow skin healing

Research suggests that some individuals who experience discomfort with regular milk report fewer digestive symptoms and lower inflammatory markers when consuming milk that contains only A2 beta-casein.

This doesn’t mean milk is “bad,” or that A1 milk is harmful for everyone. It simply highlights how individualised our responses can be.

If dairy has been problematic for you, you don’t necessarily have to eliminate it forever. You might consider experimenting—slowly and intentionally—with alternatives such as:

  • A2-only cow’s milk, clearly labeled in stores

  • Milk from Jersey or Guernsey cows (often higher in A2, though not guaranteed)

  • Goat or sheep milk, which naturally contain A2 beta-casein

As always, listening to your body matters more than following any single rule.

Symptoms are not failures. They’re feedback.

Your body is constantly communicating to you; digestively, hormonally, through the skin. When we approach health with curiosity instead of frustration, we often uncover simple adjustments that make life feel noticeably better. Sometimes, one small change - like choosing a different type of milk - can reduce inflammation, ease digestion, and support clearer skin.

That’s the heart of holistic health: not perfection, not restriction.  It is about informed, compassionate choices that support your whole system.
