How high a protein diet can affect kidney health?
This discussion will explore the risks associated with a high protein diet, and how it may impact kidney health. In my role as an obesity specialist I've encountered many questions about this subject, particularly in the recent past due to the increasing popularity of high protein diets like the Atkins Paleo and Keto. We want to give you a comprehensive understanding of this topic based on scientific studies and research.
It is important to understand the risks associated with high-protein diets on kidney health.
It's no secret that high-protein diets are good for weight loss, but they must be balanced. Over-consuming protein can be harmful to the kidneys, especially if you consume more than what your body requires. The kidneys filter wastes from blood including the ones produced by the metabolic process of protein. Protein can cause kidney damage if consumed excessively. The risk of kidney damage is higher for those with existing kidney disease. Their organs' filtering ability is already impaired.
Noteworthy points
Consult a health care provider or nutritionist before adopting a diet high in protein. You can be guided towards a healthy diet that is tailored to your health needs. Staying hydrated when following a diet high in protein is also important, because water aids the kidneys with the elimination of waste products produced during the metabolism of proteins.
Kidney health risks associated with high-protein diets
- Chronic Kidney Disease - Research shows that consuming a diet high in protein for a long time can cause Chronic Kidney Disease.
- Glomerular filteration rate (GFR), which is increased by high protein consumption, can lead to hyperfiltration of the kidneys. This may increase the GFR over time and cause kidney damage.
- A high-protein diet can raise the risk of developing kidney stones. Citrate levels in urine, which help to prevent the formation of stones, may be reduced by high-protein diets.
- Acidosis: A high-protein diet is often rich in sulfur. This can cause a buildup of acids in body fluids.
- Dehydration: The protein metabolism uses more water to dispose of the waste product urea. Dehydration can result if not enough water is consumed.
Other Tips
Remember that all proteins are not created equal. It can be healthier to choose lean protein sources like fish, chicken and lentils over red meat. Include a wide variety of vegetables, fruits and whole grains in your diet.
Conclusion
While high-protein eating may help with weight loss and improve kidney function, the potential negative impact of such diets on health is not to be ignored. You should approach these diets cautiously and with an understanding of the importance for balance and moderation. Consult a health professional before you make any significant changes in your diet.
