According to the National Kidney Foundation, high alcohol intake can cause changes in the function of the kidneys and make them less able to filter the blood. In addition, alcohol dehydrates the body, which can affect the normal functioning of cells and organs, including the kidneys.

High alcohol intake has profound negative effects on the kidneys and their role in maintaining the body’s fluid, electrolyte and acid-base balance. This in turn can increase the risk of a host of kidney-related problems.

Consuming high-sodium foods

A way to lower your dietary salt intake is by following the DASH Diet. DASH is an acronym for the Dietary Approaches to Stop Hypertension.

Artificial Sweeteners

Animal Protein (Meat)

Diets high in animal protein can cause kidney damage. A high-protein diet may cause or exacerbate existing kidney problems because protein metabolism places a heavy load on the kidneys, making it difficult to eliminate its waste products.

A study showed that a diet rich in animal-based proteins could also increase the risk of developing kidney stones from uric acid, Considerd as foods bad for kidneys, while a vegetarian diet lowered the uric acid and prevented formation of stones. Uric acid is one of the common causes of kidney stone and is a byproduct of eating foods bad for kidneys that are high in purines such as meat, seafood, and fish.

Animal protein metabolism leaves an acidic residue in the body. Because your body favors an alkaline state, it pulls calcium and other mineral salts from the bones in order to return you to that alkaline state. This calcium can form calcium oxalate kidney stones.

Carbonated Beverages

Carbonated beverages, such as sodas and energy drinks, are associated with the formation of kidney stones as well as kidney disease.
