Ever since leaving Australia in 2007 I have been missing my daily dose of Vegemite a yeast spread delicious on toast with melted butter, luckily my mum helps with the cravings by sending a supply to me. Vegemite Discovery: Ever since World War ll Australian troops have depended on Vegemite for a taste of home. Vegemite dates back to 1922 when a chemist developed a spread from one of the richest known natural sources of the vitamin B group - Brewers Yeast. Australian doctors started recommending Vegemite as a convenient source of vitamin B after it was approved by the British Medical Association in 1939 | | | | | | | |
