With all the buzz about following a healthy diet to keep up with the demands of the body, we are conscious about what we eat and how much we eat, now more than ever. It is well known that too much of anything is bad, this holds true even in the case of a high protein diet. Your dietician might suggest that you try a high-protein/ low carb diet to efficiently lose weight. These plans are based on deriving most of the needed calories (30%-50%) from protein. However, the best nephrologists will warn you about keeping an eye on your kidney function if you plan on taking up a high protein diet.
There are so many contrasting articles about high protein diets that often people do not know what to believe. This article aims to give you a clear picture regarding the same. The increasingly popular rapid weight-loss diets are mostly based on a high-protein intake with a restriction on the amount of carbohydrates. It is alright for a healthy kidney to undergo such a practice, but people with kidney conditions need to be watchful.
When you ingest protein, the body produces protein waste. In the case of healthy kidneys, millions of nephrons filter this waste and successfully remove it from the body through urine. But, when the kidneys are not healthy, the ability of the kidney to do this function is reduced and protein wastes build up in the blood. This excess of protein waste causes nausea, weakness, anorexia and taste changes. Hence it is advisable that people with high risk of kidney disease or those with one kidney only, avoid the intake of high protein.

Honestly, it is hard to know exactly how much protein is needed; it depends on multiple factors. But unless you are eating a very low amount, there will not be any detrimental health effects. It is recommended that a considerable amount of a protein form a part of every meal i.e. at least 25g/meal; you can make use of your hands for a rough guideline on this. However, this varies from individual to individual depending on size and weight. Protein shakes could also help achieve the protein target but shakes are not considered essential and they are viewed more as a performance food. Studies show that intake of daily protein is beneficial and helps in retaining muscle mass while dieting; it also improves satiety and optimizes muscle gain. As we age it becomes much more difficult to build and retain muscle mass; a significant decline in muscle mass is observed in women post-menopause. Therefore, it is highly important to ensure sufficient protein intake while optimizing the amount of food consumed.
If a person with a severe kidney condition stops eating protein, then the kidneys could be saved is a common misconception. Eating protein plays a major role in keeping a person healthy and there are chances of malnutrition and more illnesses when protein is cut off. So, the solution is to eat enough protein for maintaining health. The protein requirement of people suffering from kidney disease varies from person to person; a person undergoing dialysis has greater protein requirements than a person who is at a different stage of kidney disease. As the protein requirement varies from person to person, finding the best nephrologist and consulting him/her would be the wisest choice. However protein foods that are rich in phosphorous are best avoided.
The Bottom Line
In healthy adults, increased protein intake does not strain the kidneys much. However, it is always advisable to get in touch with a dietician or nutritionist before starting any dietary regime. With an existing kidney condition, consulting a doctor is the best way to determine protein intake.
