Is Cheese Good for Your Gut?

No, but most of the cheese we eat every day is.

The problem lies not in cheese itself, but in its industrialisation. Processed cheese products contain emulsifiers, preservatives, and synthetic colorings, and are made from pasteurised milk from which all living bacteria have been destroyed. The result is a product that delivers calories, but very little nutrition.

Real cheese, made from raw or minimally processed milk, with living cultures and an ageing period of several months, is an entirely different story. Research shows that traditionally made cheeses are rich in vitamin K2, CLA (conjugated linoleic acid), and living probiotic bacteria. From a holistic perspective, this is not a guilty indulgence but a fermented food with a direct positive impact on your health.

The rule is simple: the fewer ingredients on the label, the better the cheese is for you.

The difference comes down to one step: pasteurisation and that step changes everything.

During pasteurisation, milk is heated to at least 72°C to kill harmful bacteria. That sounds sensible, but the problem is that this process also destroys all beneficial bacteria, enzymes, and some of the heat-sensitive vitamins. The milk is safe, but nutritionally poor.

Raw milk cheese in French “au lait cru” skips this step entirely. The milk goes straight into the cheese-making process, including all its living micro-organisms. During ageing, these bacteria multiply and produce the complex flavours, probiotic cultures, and enzymes that make the cheese so special.

In practical terms: a long-aged Parmigiano Reggiano (DOP, 24+ months) contains the same Lactobacillus strains you find in expensive probiotic supplements. The industrial supermarket version? Virtually none.

When buying, look for: “lait cru,” “rohe Milch,” “raw milk,” or “DOP/AOP” designations. Those are your guarantee.

Not all cheese is equally rich in probiotics, these are the four strongest choices:

Parmigiano Reggiano (aged 24+ months) is the undisputed champion. The long ageing process results in a high concentration of lactic acid bacteria and also makes the cheese completely lactose-free through fermentation. Ideal if you are sensitive to lactose but still want to benefit from the nutritional value of dairy.

Gruyère or Comté (AOP, traditionally made) are both Swiss and French hard cheeses with a rich bacterial culture. Look for the AOP designation, it guarantees traditional production using raw milk.

Roquefort or other raw sheep’s milk cheeses naturally contain more CLA and omega-3 fatty acids than cow’s milk. Blue cheeses also contain Penicillium roqueforti, a mould culture with demonstrated anti-inflammatory properties.

Brie or Camembert de Normandie (lait cru) are soft cheeses that contain living cultures, but only in their raw milk version. The industrial variant is pasteurised and loses the vast majority of its probiotic value. Read the label carefully.

For many people: yes and more than you might think.

Lactose intolerance means your body has difficulty digesting lactose, the milk sugar naturally present in dairy. The good news: fermentation and ageing break down lactose to a significant degree.

Long-aged hard cheeses such as Parmigiano Reggiano (24+ months), aged Gouda (48+ months), and Gruyère contain virtually no lactose after ageing. The lactic acid bacteria convert the milk sugar into lactic acid during the fermentation process. Research confirms that people with lactose intolerance generally tolerate hard, long-aged cheeses without any issues.

Fresh cheeses such as ricotta, cottage cheese, or mozzarella still contain significant amounts of lactose and are therefore less suitable.

From a holistic perspective, this also makes sense: it is not dairy that is the problem, but the processed, non-fermented version of it. Your gut responds to what has — or has not, been done to food before it reaches your plate.

The question is less about “how much” and more about “which.” But if you want a guideline: 30 to 40 grams of quality cheese per day is more than enough to reap the benefits.

By comparison: 40 grams of real Parmigiano Reggiano gives you more probiotic value, vitamin K2, and bioactive fatty acids than 150 grams of processed supermarket cheese. Eating more of the wrong kind adds nothing. Eating less of the right kind is already worthwhile.

Pair cheese with fibre-rich foods whenever possible, raw vegetables, sourdough bread, or nuts. Fibre feeds your gut bacteria and amplifies the effect of the probiotic cultures in your cheese. Avoid combining it with a lot of sugar; that suppresses the growth of beneficial bacteria.

And eat your cheese at room temperature. Cold suppresses the activity of living cultures. Let your cheese sit outside the fridge for 20 minutes — you’ll immediately notice the difference in flavour as well.
