"Ragnar Berg (September 1, 1873 – March 31, 1956) was a Swedish-born biochemist and nutritionist who worked most of his adult life in Germany. He is best known for his theories on the importance of acid-base balance and inorganic minerals like calcium in the diet; later in life he endorsed vegetarianism and ways to prolong the human life span. He promoted an alkaline rich diet and also invented the alkaline dietary supplement Basica, which Volkmar Klopfer manufactured and marketed from 1925." - (en.wikipedia.org 17.02.2022)
