June 28, 2012 - New research shows weight loss surgery can reverse the effects of kidney disease. Doctors in Taiwan looked at severely obese people with the condition. They found a year after bariatric surgery, those patients saw significant improvements in kidney function. Researchers say weight loss lowers blood pressure and blood sugar levels which are the two main culprits of kidney disease.

Also, people who live in sunny areas are less likely to get pancreatic cancer, especially if they're fair skinned. Australian researchers followed 700 people and found those exposed to the highest levels of sunlight had a 24 percent lower risk of developing pancreatic cancer. And those with the most sensitive skin had a 49 percent lower risk. Researchers believe vitamin D gained from sun exposure plays a role, but say more studies are needed to determine the exact link.
