What unhealthy food choice would most likely cause kidney problems if consumed in sufficient quantities over time?

Consuming foods that are high in salt content over time can lead to kidney problems due to the increased burden they place on the kidneys. The kidneys play a crucial role in filtering excess sodium from the bloodstream. When an individual consumes excessive amounts of salt, the kidneys must work harder to eliminate this sodium. This increased workload can lead to elevated blood pressure, as high sodium intake is known to cause the body to retain water, resulting in increased volume and pressure in the bloodstream.

Chronic high blood pressure is a significant risk factor for kidney disease, as it can damage the delicate blood vessels in the kidneys, impairing their function over time. Moreover, excessive salt intake can lead to the development of kidney stones and may contribute to the development of conditions such as chronic kidney disease (CKD).

While the other options may be related to general health issues, they do not specifically pose the same direct and significant risk to kidney function as high salt intake. Whole grains, vitamin D, magnesium, and added sugars can affect the body in various ways, but an overconsumption of salt stands out as a particularly damaging factor for kidney health.
