Consuming sufficient amounts of protein has the following benefits for muscle health:
- Promotes muscle growth and repair
- Reduces muscle loss during aging
- Improves muscle recovery after exercise
Safety of protein intake for muscle health
Consuming high amounts of protein can lead to the following side effects:
- Kidney damage
- Dehydration
- Weight gain
Risk factors of protein intake for muscle health
People with kidney disease or diabetes should limit their protein intake and consult a healthcare professional before increasing their protein consumption.
