Written by Chanida Jiraroongrojana • February 28, 2026

Protein is one of the five essential food groups and a vital nutrient for overall health. Every cell in your body — from muscles and bones to hair and internal organs — contains protein.


Why Is Protein Important?

  • Repairs damaged cells and builds new ones
  • Supports normal function of organs and tissues
  • Essential for muscle growth, cartilage, blood cells, hormones, and enzymes
  • Promotes growth and development in children, teenagers, and pregnant women

Without adequate protein intake, the body cannot function at its full potential.


What Foods Contain Protein?

1. Meat and Poultry

High-quality protein sources. It is recommended to limit skin intake due to saturated fat content.

2. Fish

Provides protein and omega-3 fatty acids, which support heart and brain health.

3. Eggs

An affordable and complete source of protein.

4. Legumes and Nuts

Plant-based protein sources such as soybeans, almonds, peanuts, and lentils.

5. Whole Grains

Examples include quinoa and wheat germ.


5 Reasons to Add More Protein to Your Meals

  1. Keeps you full longer and reduces unnecessary snacking
  2. Supports lean muscle development and a toned body
  3. Strengthens bones
  4. Boosts metabolism and fat burning
  5. May help reduce the risk of high blood pressure

How Much Protein Should You Eat Per Day?

  • Teenage boys and adult men: about 7 ounces (~200 grams) per day
  • Teenage girls and adult women: about 6 ounces (~170 grams) per day
  • Children (2–6 years), women, and elderly individuals: about 5 ounces (~142 grams) per day

Can You Eat Too Much Protein?

Excessive protein intake may cause the liver and kidneys to work harder to eliminate waste. Over time, consuming too much protein may increase acidity levels in the blood and contribute to fat storage if calorie intake exceeds daily needs.


Conclusion

Protein is essential for maintaining strength, supporting body repair, and promoting overall well-being. However, balance is key. It is important to consume protein from diverse sources while maintaining a diet rich in vitamins, minerals, and healthy fats.
