Eat Balanced: Attention Health Enthusiasts. Let’s Discuss the Risks of a High-Protein Diet.

by OK2BU 2025. 1. 28.

Protein is an essential nutrient for building and maintaining the body, playing a crucial role in muscle formation and recovery. As a result, many people increase their protein intake to improve their health and physique. However, excessive protein consumption can harm your health. In this post, we’ll explore the major issues that arise from overeating protein and discuss how to ensure proper intake to prevent these problems.

 

Eat Balanced: Attention Health Enthusiasts. Let’s Discuss the Risks of a High-Protein Diet.
Protein is a vital nutrient for muscle growth and overall health.

 

Health Issues Caused by Excessive Protein Intake

Constipation: Protein Intake Can Harm Digestive Health

Increasing protein intake can lead to a higher likelihood of constipation.

  • Cause:
    The metabolism of protein produces urea, which is excreted through urine, consuming a significant amount of body fluid. When there’s not enough water in the colon, the stool becomes hard and difficult to pass.
    High-protein diets also tend to reduce the intake of fiber-rich foods like vegetables and fruits, further aggravating constipation.
  • Prevention:
    • Stay Hydrated: Drink plenty of water alongside protein-rich foods to maintain proper fluid balance.
    • Include Fiber: Ensure your diet includes vegetables, fruits, and whole grains to maintain a balanced intake of fiber.

Kidney Dysfunction: Overloading the Kidneys

Excessive protein intake puts strain on the kidneys, potentially leading to decreased kidney function.

  • Cause:
    The byproducts of protein metabolism, like urea, are filtered and excreted by the kidneys. Excessive protein intake increases the filtration burden on the kidneys, which can damage them over time.
  • Symptoms:
    • In the early stages, symptoms may not be noticeable.
    • As it worsens, symptoms like swelling around the eyes, foamy urine, and weight loss may appear.
  • Prevention & Management:
    • Regular health check-ups, including testing the glomerular filtration rate (GFR), which should be between 90-120 mL/min.
    • Keep protein intake within recommended amounts and ensure adequate water consumption to protect kidney health.

Gout: Excessive Protein Can Trigger Pain

Gout is closely related to protein intake.

  • Cause:
    High-protein foods, especially red meats and organ meats, are rich in purines. When purines are metabolized, they produce uric acid, which can accumulate in the joints if not excreted properly, leading to gout.
  • Symptoms:
    • Severe pain and swelling in the joints, often starting in the toes and potentially spreading to other joints like the knees and elbows.
  • Prevention:
    • Limit foods high in purines (red meat, organ meats, some seafood).
    • Reduce alcohol consumption, as it can inhibit uric acid excretion.

 

The Importance of Balanced Protein Intake and a Well-Rounded Diet

While protein is an essential nutrient, it’s critical to maintain balance with other nutrients.

Recommended Protein Intake

  • The daily recommended protein intake for adults is 0.8-1g per kilogram of body weight.
    For example, a person weighing 70 kg should consume approximately 56-70g of protein daily.

Balance with Carbohydrates

  • Carbohydrates serve as an energy source for muscles, supporting muscle cell synthesis and preventing muscle loss.
  • When following a high-protein diet, it’s important not to drastically reduce carbohydrate intake, as this can lead to energy deficiencies.

The Role of Fiber

  • Fiber is essential for preventing constipation, aiding digestion, and maintaining gut health.
  • Include vegetables, fruits, nuts, and whole grains to maintain a healthy balance of fiber with protein.

The Need for Fats

  • Healthy fats (like omega-3 fatty acids) reduce inflammation and support cell function.
  • Even on a high-protein diet, it’s important to incorporate healthy fats to ensure overall health.

 

Proper Guidelines for Protein Intake

Diversify Protein Sources

  • High-Quality Protein: Chicken breast, fish, eggs, beans, tofu.
  • Plant-Based Protein: Lentils, chickpeas, quinoa, which are lower in purines compared to animal-based proteins and place less strain on the body.

Timing of Meals and Exercise

  • Consuming protein after exercise maximizes muscle recovery and growth.
  • Aim for balanced meals with appropriate amounts of protein and carbohydrates.

Stay Hydrated

  • Adequate fluid intake is essential to help the body excrete byproducts of protein metabolism.

Be Cautious with Supplements

  • If using protein supplements, follow the recommended dosage and avoid excessive intake.
  • Overuse of supplements can put strain on the kidneys and liver.

 

Conclusion: A Balanced Diet Is Key to Health

Protein is a vital nutrient for muscle growth and overall health. However, excessive protein intake can lead to health issues such as constipation, kidney damage, and gout. If you wish to increase protein intake, ensure that it is balanced with other nutrients, and maintain proper hydration and exercise.

As the saying goes, "Too much of anything is as bad as not enough", moderation and balance are essential for maintaining health. Practice a well-rounded diet to keep your body in optimal condition!
