Studies conducted in the United States and Japan have shown that a diet rich in fruit and vegetables can create an alkaline environment in the body that helps to preserve kidney health. In contrast, a diet loaded with animal protein produces an acidic environment that can accelerate a decline in kidney function.
“Vegetable protein is highly alkaline and may counteract the effects of an increased acid load within the human body, which can pose a problem for many physiological functions, including those of the kidneys,” said AUSVEG spokesperson, Hugh Gurney.
One of the US studies, conducted by the Texas A and M University College of Medicine, found that the kidney function of patients with hypertensive nephropathy who received extra dietary fruit and vegetables, or an oral alkaline medication, was preserved after one year. Kidney injury in those who received no intervention had progressed.
“These findings add to the wealth of evidence and studies highlighting that vegetables are good for human health, and should encourage all people to increase their consumption to help protect against conditions such as kidney disease,” said Mr Gurney.
Another study by the Tokyo Kyosai Hospital looked at data from 249 chronic kidney disease (CKD) patients across Japan. It was found that patients with elevated acid levels had an increased risk of CKD progression, compared to those with low levels. Vegetables can also help with cardiovascular health.
“Elevated levels of low-density lipoprotein (LDL) cholesterol in the bloodstream can increase the risk of cardiovascular disease, such as heart attack and stroke, however, the consumption of vegetables like beans, broccoli and cabbage can lower these levels and prevent disease,” said Mr Gurney.
