Kidneys are among one of our most vital organs. They filter out any impurities, waste materials and excess substances to make sure our bodies can function properly. Interestingly, they are also extremely delicate, and the slightest damage can have a negative effect on the rest of our body.
A high salt diet alters the sodium balance, causing the kidneys to have reduced function and remove less water resulting in higher blood pressure. This puts a massive strain on the kidneys and can lead to kidney disease. Moreover, a diet high in salt has been shown to increase the amount of protein in the urine which is a major risk factor for the decline of kidney function

People with kidney problems should stay away from high protein diets. The same also goes for dairy products as milk and cheese contain high levels of protein. Protein can be highly acidifying, and that’s regardless of whether it comes from a cow, a sheep or a goat.
Caffeine consumption has been linked to kidney stones. Also, as caffeine is a stimulant, it’s long-term use can increase the risk of renal failure if the kidneys are already damaged. Consuming even small amounts of caffeine on an empty stomach can cause kidney stones. It is best to consume teas/coffee in moderation.
