3 warning signs that may indicate that you are eating too much protein

Protein is one of the main elements of our diet, as it provides our bodies with amino acids and keeps us alive. However, despite its many benefits, excessive consumption may have a negative impact on human health.

According to the Cleveland Clinic website in America, citing nephrologist Juan Kayle, the kidneys work to purify the body of waste, acids, and excess fluids. When you eat too much protein, the amount of material that has to be filtered and processed increases.

This task may become more difficult with age, as the efficiency of the organs gradually declines over the years. A diet that is very high in protein can contribute to high levels of inflammation and oxidative stress in the body, which can make it difficult for other vital organs to function optimally.

The 2025-2030 Dietary Guidelines for Americans suggest that adults eat between 1.2 and 1.6 grams of protein per kilogram of body weight per day. If the kidneys are working properly, increasing protein intake is usually safe, especially for athletes, according to the Cleveland Clinic website in America.

But in general, Dr. Kaye advises avoiding excessive protein intake due to its effects, even in healthy people, with the need to achieve balance in the diet. When it comes to the burden that proteins place on the kidneys, not all types are the same.

Dr. Kaye explains that animal proteins, such as meat products, tend to produce greater amounts of acids that the kidneys have to eliminate from the body. In contrast, plant proteins tend to be easier for the body and kidneys to process.

The same applies when using protein powder as a supplement, as powders made from plant ingredients are less stressful on the kidneys than those made from animal proteins. In the early stages, many people may feel perfectly fine, even though kidney damage continues and worsens.

The Cleveland Clinic website in America explained that kidney problems are often discovered only after abnormal results appear in a routine blood or urine test. However, possible warning signs may include: Therefore, it is important to consult a healthcare professional before making any major changes to your protein intake.

This is even more important if you suffer from health problems, such as high blood pressure, or have a family history of kidney disease.
