I'm afraid of cheese
What is it about cheese that you are afraid of personally?
People say that cheese makes you fat. I have also heard that it can cause cancer and make you live a shorter amount of time. I would just rather be safe than sorry.
That's an understandable reason to be afraid to eat something. But, taking advice from people other than doctors can often give conflicting information.
I'm also not sure if I can eat it because I'm a vegetarian.
There are vegan friendly cheeses as well as a lot of good fat-free cheese options. But, for your piece of mind, If you're worried about the long term effects, it might be worth talking to a nutritionist.
