High Soda Intake
After analyzing 14 studies, researchers at Columbia University's Mailman School of Public Health discovered that people who consumed more than 8.5 ounces of sugar-sweetened soda a day had an increased risk of developing pancreatic cancer, one of the most elusive and deadliest diseases, by as much as 19 percent compared with those who didn't drink soda. (Diet soda wasn't tested.) The sugar rush that occurs after you down fizzy drinks causes the pancreas to increase insulin production; as a result, pancreatic cells may be exposed to a higher concentration of insulin than other cells in the body are. This may create an imbalance that researchers believe could spur cancer growth. Try cutting back by replacing one soda a day with a glass of water.
