What does bacteria in milk do? I know it gives you Crohn's diease. And how is it benefial?

Bacteria are around us everywhere. Bacteria live around us, on us, and inside us. Bacteria in milk can come from the cow, or get in to the milk after it leaves the cow. A process called "pasteurization" kills some of the bacteria to make the milk last longer before it spoils.

The exact cause of Crohn's disease is not known. So it's not quite right to say that milk, or bacteria in milk 'cause' Crohn's disease. Eating milk or other foods might make some people with Crohn's disease sick, but the cause of the disease is still not fully understood by scientists.

The bacteria in milk are beneficial in a lot of ways -- bacteria make milk products like cheese. Bacteria in our guts help to keep us healthy by keeping disease-causing bacteria out. In cows, bacteria help digest the grass they eat. There are tons of ways bacteria are helpful, and these are just a few!

Hope this helps,
