Re: food and cervical cancer
I think snobun hit most of the essentials!
Green tea is EXCELLENT -- try and have 2-3 cups a day and try and buy it in its loose-leaf form (better than bagged tea). It's also a good coffee substitute as it still has some caffeine.
Eliminate all sodas if you're a soda drinker-- there is absolutely no nutritional value to them! It's okay in moderation but try and cut them out of your diet if possible. If you're a coffee drinker, try to limit it to one cup every other day -- if you can cut it out of your diet, even better! I definitely need my coffee though so I'm limiting myself to 3 coffees a week (only when I realllly need it when I'm studying).
Eat LOTS of dark, leafy vegetables -- spinach is LOADED with folate and is pretty yummy, I think (easy to make a spinach salad for dinner every night). Broccoli, brussel sprouts (not my fav, personally, haha), kale, collard greens, edamame, etc...basically any veggie that has a dark green tint to it is excellent for you. My doctor recommends at least 3-4 servings of veggies a day (one cup per serving).
Eat a serving or two of fruit a day, especially fruits that have a dark peel to them (blueberries are excellent, strawberrries, blackberries, boysenberries, plums, etc).
Eat lots of FISH especially salmon and cod-- my doctor suggests trying to follow a pescatarian diet and limit red meat consumption to once or twice a month.
Try and limit your consumption of foods with refined sugars and flour and if you like white rice, replace it with brown.
That's all I can recall right about now. I'm sure there are other things, but perhaps you could consult a nutritionist in your area? They may be better to help you and your particular health concerns. Take care!
