A study published in Applied Physiology, Nutrition, and Metabolism found that the compounds found in grape seed and skin can reverse kidney damage caused by a high fat diet [2]. Obese people are more prone to kidney damage as it can lead to depletion of copper from the kidney, among other complications. The study suggests using grape seed and skin extracts as a preventive supplement for patients at a high risk of kidney disease due to obesity.

Prevention of kidney disease

Around 50% of patients suffer from acute renal failure due to inadequate blood supply to the kidneys, or what is known as ischemia. Grapes have anti oxidant and anti-inflammatory mechanisms as the compound resveratol reduces the risk of damage caused by ischemia [3]. Resveratol was found to have a protective effect in rats kidneys who were suffering from tissue damage caused by the return of blood supply to the kidneys, after a period of lack of oxygen supply or ischemia. This study was conducted by Italian doctors from the University of Milan in 2013.

Reduction of renal disturbances

Iranian researchers found that 50 mg of grape seeds extracts a day for two weeks may reduce kidney function disturbances following tissue damage caused by ischemia [4]. The study was conducted on 32 rats in 2013 and researchers hope that this finding will be able to reduce the harmful effects of renal disturbances. Here are 5 other foods that can help you recover from kidney disease.
