A recent study examined whether consuming sugary products (including sugary drinks) causes an improvement of mood and alertness - a "sugar rush" - and found that to be a total myth. After reviewing 31 studies (in which 1259 individuals participated), the researchers found that people do not get a "sugar rush" with an improvement in mood from consuming sugary products - instead it makes people feel less alert and more tired within an hour of ingestion.
From Science Daily: No such thing as 'sugar rush'! Sugar worsens mood rather than improving it
Sugar does not improve mood and it can make people less alert and more tired after its consumption -- according to a new study by the University of Warwick, Humboldt University of Berlin, and Lancaster University. ...continue reading "No Such Thing As A Sugar Rush"
Great article about cancer and sugar. Yes, there is more and more research recently finding a connection with sugar, raised insulin levels, and cancer (as in sugar feeds cancer). Do go read it. Some excerpts from the May 15 Sunday magazine of the NY Times:
AN OLD IDEA, REVIVED: STARVE CANCER TO DEATH
Today Boveri is celebrated for discovering the origins of cancer, but another German scientist, Otto Warburg, was studying sea-urchin eggs around the same time as Boveri. His research, too, was hailed as a major breakthrough in our understanding of cancer. But in the following decades, Warburg’s discovery would largely disappear from the cancer narrative, his contributions considered so negligible that they were left out of textbooks altogether.
By the time Warburg turned his attention from sea-urchin cells to the cells of a rat tumor, in 1923, he knew that sea-urchin eggs increased their oxygen consumption significantly as they grew, so he expected to see a similar need for extra oxygen in the rat tumor. Instead, the cancer cells fueled their growth by swallowing up enormous amounts of glucose (blood sugar) and breaking it down without oxygen. The result made no sense. Oxygen-fueled reactions are a much more efficient way of turning food into energy, and there was plenty of oxygen available for the cancer cells to use. But when Warburg tested additional tumors, including ones from humans, he saw the same effect every time. The cancer cells were ravenous for glucose.
Warburg’s discovery, later named the Warburg effect, is estimated to occur in up to 80 percent of cancers. It is so fundamental to most cancers that a positron emission tomography (PET) scan, which has emerged as an important tool in the staging and diagnosis of cancer, works simply by revealing the places in the body where cells are consuming extra glucose. In many cases, the more glucose a tumor consumes, the worse a patient’s prognosis. ...continue reading "Sugar and Cancer"
