For your consideration ...
Actually, he was trying to bring back constitutional money by creating a US issued currency backed by, and redeemable in, silver dollars, by authorizing the US Treasury to do so. He did this with Executive Order 11110 signed on June 4, 1963. However this idea, order, was in direct competition with Federal Reserve Notes, which he wanted to replace with US Silver Certificates. Which of course did not go over well with the Federal Reserve owners, monopolists, maniacal international psychopaths, are like this. He was assassinated five months later, on November 22, 1963. Then, after his assignation, only four months later in March of 1964, redemption of silver certificates for silver dollars was halted. Soon after, silver altogether was removed from our coinage. The factual timeline sure sounds conspiratorial, doesn't it?
But remember .... There was, we still had, a quasi gold backing system still in place at the time Kennedy was President, through the Bretton Woods agreement that pegged the US Dollar to $35 to an ounce of gold, that kept the dollar pretty much stable here, and with import/export trading countries. Of course the Bretton Woods agreement was not for the people, as we could not redeem our dollars for gold, since all US gold certificates were pulled from circulation, and any held by people that still had them could not redeem them.
Kennedy was trying to do something for, and for the benefit of, the American people, and it got him killed. Kinda akin to what is happening with Trump becasue he was, (and is till trying), putting the America people, and their interests first.
Nutrition hasn't been bred out. It's that the soil used to grow these, and other vegetables, has been extremely depleted of all minerals and nutrients. Farmers do not use natural organic composted materiel anymore, relying solely on chemical fertilizers. That's why garden grown vegetables taste so much better. Because good gardeners, know the value of composting and replenishing the soil with natural organic materiel.
In Germany, many farmers that also raise livestock, save the excrement and compost it for a while, along with the urine that is stored in underground tanks, then some spring, they spread it over their fields. Replenishing the soil with a natural fertilizer.
