Summary
The purpose of this study is to see if taking a medication can lower the amount of oxidants from food that go into our body. Previous research shows that if the investigators lower the oxidants from food in people with diabetes, this simple change lowers different risks for heart disease and the worsening of kidney disease. The investigators focus on a specific type of oxidant, advanced glycation endproducts (AGEs). A previous, smaller study, conducted by our group showed that a drug, already approved by the FDA, will lower AGEs in the investigators compared Renvela® to Tums®. Both of these drugs have few side effects and have been used for a long time in patients with diabetes and kidney disease. While our previous study was interesting, it was just too small to be able to be sure that it will help all people with diabetes, or if the good effects the investigators found were simply due to chance. The investigators are doing this new study to confirm or deny the possibility that Renvela® can really help people with diabetes and kidney disease.
