Cancer prevention: Bring home the bacon, but don't eat it

The World Cancer Research Fund carried out an inquiry into lifestyle and cancer, and issued several recommendations, BBC News Online reports.
Recommendations include:
Don't gain weight after the age of 21
Aim to be as thin as possible -- without becoming underweight.
People with a Body Mass Index (BMI) of between 18.5 and 25, are deemed to be within a "healthy" weight range
Avoid sugary drinks, reduce fruit juice consumption, limit alcohol
Don't eat processed meats like bacon, ham and salami
Limit red meat.
Exercise every day
Babies should be breastfed
Don't take dietary supplements to try and combat cancer
The report says people can adjust cancer risks by their behavior and lifestyle choices
Body fat is a seen as a key factor and more significant than previously thought. The report says evidence is convincing that body fat is key in the development of colon and breast cancers.

So basically don't be a pig, don't eat pig, and don't behave like one.
But since two-thirds of cancer cases are not thought to be related to lifestyle, I'm gonna enjoy my glass of wine, nibble on some bacon and quit fretting. I could fall under a bus tomorrow.
