Patients with chronic kidney disease can shield their kidneys from further trouble by upping the amount of fruits and vegetables in their diets. This will protect against too much acid buildup.
Hereâs the problem: the typical U.S. diet is based on meat and grain products. These are highly acidic and can lead to âmetabolic acidosis,â defined by high acid levels in the body. This is especially common among kidney disease patients, as that organ is responsible for removing acid through the urine. The condition can lead to rapid breathing, confusion, and lethargy.
To combat this, doctors use alkali supplements, but researchers say that simply eating more fruits and vegetables (which naturally have alkali) will also help.

Researchers tested 71 patients who had stage-four kidney disease, randomly giving them either added fruits and vegetables or an oral alkaline medication. After one year, here is what they found:
â¢ Both groups had similar kidney function.
â¢ Both groups had reduced metabolic acidosis and, in fact, it seemed that consuming more produce helped reduce metabolic acidosis more than the conventional treatment.
â¢ Both groups had strengthened kidneys, discovered via urine measurements.
â¢ Although fruits and vegetables are rich in potassium, levels of this mineral did not rise in either group (which can be dangerous to kidney patients).
Thus, the study proved that shopping in the produce aisle will help kidney patients maintain kidney health. People who may have a harder time following a diet high in fruits and vegetables can use nutritional supplements on the side. This will be effective as well.
This is a big area of kidney disease research, and it further illustrates the power of simple nutrition.
