20110229620 | Novel natural mixed sweetener - It is well known that excessive use of plain table sugar—sucrose—in eg coffee and tea, (especially caffeinated), can within hours cause human blood sugar levels to initially rise and then quickly drop so low as to cause symptoms of fatigue and confusion . . . as the brain is no longer getting an adequate supply of sugar. This became problematic for me when I was unemployed so I decided to formulate an alternative sweetener. The end product is described in this paper. | 09-22-2011 |
20110229621 | Novel natural mixed sweetener - It is well known that excessive use of plain table sugar—sucrose—in eg coffee and tea, (especially caffeinated), can within hours cause human blood sugar levels to initially rise and then quickly drop so low as to cause symptoms of fatigue and confusion . . . as the brain is no longer getting an adequate supply of sugar. This became problematic for me when I was unemployed so I decided to formulate an alternative sweetener. The end product is described in this paper. I personally have used this sweetener for over nine months and never experience the aforementioned symptoms which I did have with plain table sugar. | 09-22-2011 |
