The data also clearly show you get a benefit even if you don't eat five servings a day. One serving a day gives you very roughly a 10 per cent relative mortality benefit, two servings, a 15 per cent benefit, three servings, a 20 per cent benefit, four servings, a 25 per cent benefit -- and then once you get to five servings, that is basically it.
What you probably don't know: Many of us, right now, may be unintentionally over-dosing on our medications. In some cases, as little as one quarter or one eighth of the original recommended dosage ends up being shown to be either equally effective or at least to provide an important benefit -- with fewer side effects. So how can you know what's the best dose for you?
Have you been told by your health care professional that you have high blood pressure, high cholesterol or type 2 diabetes and you need to do something to improve your "numbers?"
