Estimates that mineral levels in vegetables have dropped by up to 90% since 1914
Something that has puzzled me recently: how is anyone supposed to get the daily recommended amount of potassium? If you look at foods like bananas that are supposed to be good sources of it, you still need to eat something like eleven bananas a day to get enough (according to US recommended daily intakes, anyway). At least with the minerals mentioned in this posting, you can fall back on supplements if you need to...but if you try to buy potassium supplements, the max dosage you can get over the counter is 99mg, which is only about 3% of the daily recommended intake. WTF?
