What do i need to do to reduce my high cholesterol?

My doctor's secretary called me and told me that my cholesterol is kinda high and I need to watch what I eat and come back for a blood test in one month. I'm not quite sure what I should be eating.

wow, I didnt know you could have high cholesterol at 20
avoid fried foods, oils, butters etc
eggs, red meat (beef, pork, duck, lamb), cream cheese, chedder cheese, sponge cake

Eat lots of vegetables, avoid fattening foods, eat fish - if you talk to your doctor there are capsules that can help bring it down as well if the healthy eating doesn't help.

do not eat eggs or avacodoes.
