Researchers from the University of Glasgow have discovered that fat negates the anti-cancer properties of vitamin C. Through laboratory experiments, they detected that vitamin C or ascorbic acid cleared the stomach of the cancer-causing compound, which was a result of saliva and food combining with the acid in the stomach. However, the ascorbic acid could no longer fight the cancer-causing compound when fat was added to the combination. The researchers feel that their findings emphasize the value of a balanced diet with a low intake of fat.
Another group of researchers has suggested that a fat hormone encourages the development of colon cancer. Scientists from the University of California, San Diego, studied the results of leptin, the fat hormone, on three cell lines. They discovered that an increase in leptin led to an increased growth of colon cancer cells in all the cell lines. Their conclusion was that people with a greater amount of leptin were at an added risk of suffering from colon cancer. Since obese people have a higher amount of fat cells, they also have a higher amount of leptin. These findings will help formulate better therapies against colon cancer.
Additionally, researchers from RAND Corporation, a non-profit research organization, have received shocking results for their recent study. They found that the number of severely obese people has made a significant increase in America between 2000 and 2005. People with a Body Mass Index (BMI) of over 30 are considered obese. The study showed that people with a BMI of over 40 made a 50 percent increase and those with a BMI of over 50 made a 75 percent increase. These results have important health implications and contradict the belief that the proportion of obese people remains the same.
