Living with both kidney disease and diabetes presents unique dietary challenges. Managing both conditions requires careful attention to what you eat, as the right diet can help control blood sugar levels and support kidney health. This article provides a comprehensive guide to foods that are beneficial and those to avoid for individuals navigating these dual health concerns.
Understanding the Connection
Diabetes is one of the leading causes of kidney disease, often resulting from prolonged high blood sugar levels that damage the kidneys' filtering system. Therefore, managing diabetes effectively can help slow the progression of kidney disease. Conversely, a diet that supports kidney health can also aid in better blood sugar control, creating a synergistic effect.
