Milk and dairy — food card: calcium, protein and safety
Yogurt, ayran, cheese, cottage cheese — dairy is on our table every day. It provides protein and calcium and is often gentle to eat. This card explains the benefits of dairy and how to choose it safely during treatment.

01Short answer
02Simple explanation
Dairy gives calcium and protein, important for bones and muscles.
Pasteurisation is gentle heating that clears milk of germs.
Raw milk and cheeses made from it can carry Listeria, Salmonella and E. coli.
Hard cheeses (gouda, cheddar) are safer than soft mould-ripened cheeses.
03Scientific explanation
Raw milk: according to CDC, unpasteurised milk can cause serious infections and is especially dangerous with weakened immunity.
Listeria can grow even in the fridge, so soft cheeses and long-opened dairy are risky.
Lactose: after some chemotherapy and antibiotics, milk can cause bloating and diarrhea; yogurt and hard cheese are usually better tolerated.
04What happens in the body?
What does milk provide?
A glass of milk (250 ml) gives about 8 g of protein and 300 mg of calcium. Yogurt and cottage cheese are even richer in protein.

How to choose
Look for the word "pasteurised" on the label. Buy sealed, in-date products from a chilled shelf.

Cheeses
Hard cheeses and factory-made pasteurised white cheese are safer. Set aside blue-veined and white-rind soft cheeses.
Yogurt, ayran, kefir
Shop yogurt and ayran are made from pasteurised milk. Ask your team about live cultures.
On hard days
Cool yogurt, milk porridge and cottage cheese irritate the mouth less and give protein.
05Dairy: four steps
Choose pasteurised, swap mould cheese, warm if you like, return opened packs to the fridge.
