4. Individuals with Kidney Disease
According to researchers from the Milan Institute of Pharmaceutical Research (Italy), consuming large amounts of grains, especially bread, can increase the risk of renal cell carcinoma (RCC), the most common type of kidney cancer.
In addition, most bread varieties, especially packaged supermarket bread, contain high levels of salt. When consumed in forms like hamburgers, pizzas, or sandwiches, it can lead to excessive sodium intake, which is harmful to kidney function.
