Vigorous physical activity is advised for a total of 75 minutes per week. This could involve running alone or playing sports in groups. Moderate exercise such as brisk walking or cycling, with the aim of getting out of breath, should account for around 30 minutes five times per week.

A "balanced diet" is divided as follows:

  • Around one third fruits and vegetables (five portions of at least 80 grams each)
  • Around one third starchy foods (potatoes, wholegrain bread, pasta and rice)
  • Around one sixth protein (eggs, fish, lean meat, nuts and beans)
  • A little over one sixth dairy (milk, cheese and yogurt)
  • Limited fatty, sugary or salty foods, if at all

Green tea, soy products, beans, pulses, tomatoes, cruciferous vegetables (such as broccoli, cauliflower, cabbage and kale) and selenium (from Brazil nuts, kidney, liver and seafood, for instance) have all been linked to a lower risk of prostate cancer. Meanwhile, excessive calcium, processed, well-done or burnt red meat, saturated fats and alcohol have all been linked to a higher risk of prostate cancer and should be avoided.
