Lactose: The Sweet Secret About Milk You Might Not Know
For as long as I can remember, I’ve loved milk. A cold, fresh glass of organic milk? Delicious. There’s something nostalgic and comforting about it for me—it’s like a little piece of home in a glass. But, as much as I enjoy it, I’ve had to face some truths about how milk affects the body.
What many people don’t realize is that lactose, the main carbohydrate in milk, is actually a sugar. Yes, milk contains natural sugars—just like fruit, honey, or even a donut (though vastly different in nutritional value).
But here’s the kicker: while some of us digest lactose just fine, for others, milk can be a source of inflammation, digestive distress, and even excessive mucus production.
Why Does Lactose Matter?
Lactose is a type of sugar made up of two smaller sugars: glucose and galactose. To break it down and absorb it, your body produces an enzyme called lactase. However, as many as 65% of adults worldwide produce less lactase after childhood, leading to lactose intolerance.
When your body struggles to break down lactose, it can ferment in the gut, leading to gas, bloating, cramps, and discomfort. For some, it can even exacerbate chronic inflammation, which plays a role in conditions like arthritis, asthma, and even skin issues.
What About Dairy and Mucus Production?
Have you ever noticed feeling congested after drinking milk? Many people report increased mucus production, particularly in their respiratory system, after consuming dairy. While studies on this are mixed, anecdotal evidence is strong enough that I’ve personally cut down on my milk intake.
Could Blood Type Play a Role?
Here’s an interesting twist: blood type might influence how well your body handles dairy.
Blood Type B: Often considered the "dairy-tolerant" type, these individuals tend to handle milk and its byproducts better than others. Historically, this blood type is associated with nomadic cultures that relied on dairy as a staple in their diets.
Blood Types A and O: These individuals are more likely to struggle with dairy, as their digestive systems may be less equipped to handle it.
Of course, these aren’t hard-and-fast rules, but understanding how your unique body responds to milk can help guide your choices.
Do You Need to Cut Out Milk?
Not necessarily. Like me, you might love milk and want to keep it in your life. The key is awareness and moderation. Here’s what you can do:
Listen to Your Body: If you feel bloated or uncomfortable after drinking milk, your body may be telling you something.
Experiment: Try lactose-free options or other dairy alternatives like almond, oat, or coconut milk.
Balance Inflammation: If you enjoy milk, balance it with anti-inflammatory foods like leafy greens, berries, and omega-3-rich fish.

Milk is a complex topic—one that’s tied to culture, comfort, and personal preference. For me, it’s all about balance. I still enjoy milk (and won’t apologize for it!), but I stay mindful of how much I consume and how my body feels afterward. What about you? How does your body handle milk?
