No, that is not a typo, just ask your parents or grandparents if they have had their Vitamin P today and they will probably say “Yes” and then be impressed that you even know about it and then tell you all about it.
But if you don’t want to wait, Vitamin P is what the nutritionists / researchers called Flavonoids back in the 1930’s up until the late 1950’s. And Flavonoids are simply byproducts of plant metabolism. So anytime you eat anything that originated from a plant…it will have Flavonoids. This ranges from coffee (yes believe it or not, coffee is not manufactured inside of Starbucks), vegetables and, of course, fruits with citrus fruits containing the popular Flavonoid called Hesperidin. So when your grandparents said they had their Vitamin P today, they probably responded with “Yes, I ate my Grapefruit if that’s what you are wondering.”
Today Vitamin P is obviously not considered a Vitamin anymore but that certainly doesn’t mean that they are still not healthy for you. Flavonoids still help fight inflammation, reduce blood sugar and lipids and can even improve insulin resistance.
So next time your friend / colleague at work / or study pal starts snacking on an orange or some grapes exclaim “Oh, I see your dosing up on your Vitamin P” and let the jokes (probably first) and then the history lesson begin.
