Imagine you have been feeling a bit sluggish and tired lately. You go to the doctor and get your blood tested. Three days later, she gets back to you with the results: you have a phosphorus deficiency.
She prescribes phosphorus supplements and advices you to take them daily.
But you are curious, so you wonder why you have a phosphorus deficiency in the first place. You do some research, and you find out that you either don’t eat sufficient veggies or that your veggies might be deficient in phosphorus.
As you eat your five portions of veggies every day, you know this can’t be it. Doing more research, you find that the reason for phosphorus-deprived veggies is due to industrial, agricultural practices that deplete the soils of nutrients.
