Healthy Body and Mind

Do you have painful feelings in your body? This article is for you

In this article, we will explore the main symptoms of protein deficiency, how to prevent this condition, and ensure your diet is rich in this vital nutrient.

What Is Protein Deficiency?

Protein deficiency occurs when the consumption of this nutrient is insufficient to meet the body’s needs. While rare in developed countries, it can affect specific populations such as the elderly, athletes who do not follow a balanced diet, people with chronic diseases, or those in extreme calorie restriction situations.

Severe deficiency, known as kwashiorkor, is more common in regions where malnutrition is prevalent. Even in less severe cases, low protein intake can harm the quality of life.

Common Signs and Symptoms of Protein Deficiency

1. Swelling (Edema)

One of the most characteristic symptoms of protein deficiency is swelling, especially in the legs, arms, and abdomen. This occurs due to the low production of albumin, a protein that helps regulate fluids in the body. When albumin levels are low, fluid accumulates in tissues, causing edema.

  • Tip: To prevent this condition, consume protein-rich foods such as eggs, fish, and dairy products.

2. Changes in Skin, Hair, and Nails

Protein deficiency can leave your skin dry, your hair brittle and prone to breakage, and your nails weak. This happens because protein is fundamental for the formation of collagen and keratin, substances essential for the health of these tissues.

  • Extra Tip: Foods like nuts, seeds, and legumes are excellent plant-based protein sources for skin and hair health.

3. Weakened Immune System

Protein deficiency impairs the production of antibodies, reducing the body’s ability to fight infections. People with low protein intake may notice they get sick more frequently or take longer to recover.

4. Muscle Loss and Weakness

Muscles are primarily composed of proteins. When the body does not receive enough of this nutrient, it starts using muscle tissue as an energy source, leading to muscle atrophy. This process can cause weakness and difficulty performing daily tasks.

  • Tip for Athletes: Opt for protein shakes and foods like Greek yogurt and quinoa to maintain muscle mass.

5. Fragile Bones

Protein plays a crucial role in maintaining bone density. Its deficiency can increase the risk of fractures, especially in the elderly and postmenopausal women.

6. Stunted Growth

Children and adolescents who do not receive sufficient protein may experience stunted growth, both in height and cognitive development. This is one of the most severe symptoms of protein deficiency.

  • Alert: Ensure high-quality proteins are included in children’s meals, such as eggs and beans.

7. Weight Changes (Loss or Gain)

Low protein intake can lead to involuntary weight loss due to muscle loss. On the other hand, the lack of satiety provided by protein may result in increased consumption of carbohydrates and fats, leading to weight gain.

  • Nutritional Strategy: Include proteins in all meals to balance satiety and avoid weight fluctuations.

8. Anemia

Anemia can occur due to a diet low in proteins, which are necessary for producing hemoglobin, the protein that transports oxygen in the blood. This can result in constant fatigue and lack of energy.

  • Tip: Consume foods rich in iron and proteins, such as lean red meat, lentils, and spinach.

How Much Protein Do You Need?

The ideal amount of protein varies according to age, weight, and physical activity levels. Here are some general guidelines:

  • Sedentary adults: 0.8 grams of protein per kilogram of body weight.
  • Athletes or physically active individuals: 1.2 to 2.0 grams per kilogram of body weight.
  • Pregnant and breastfeeding women: Require an average increase of 25 grams of protein per day.

Protein Sources for a Balanced Diet

Here are some options to include more protein in your diet:

  • Animal-based: Lean meats, fish, eggs, dairy products, and seafood.
  • Plant-based: Lentils, chickpeas, soybeans, quinoa, seeds, and nuts.

When to Seek Help?

If you notice any of the mentioned symptoms or feel that your diet is not balanced, consult a nutritionist or healthcare professional. They can assess your specific needs and create a personalized meal plan.

Conclusion

Maintaining a protein-rich diet not only prevents deficiencies but also improves overall health by promoting energy, immunity, and strength. Start incorporating more protein sources into your daily meals and observe the benefits to your quality of life.
