Making the Choice
Choose Animal Proteins If:
- You prioritize complete protein sources
- You’re focused on muscle building
- You need higher iron intake
- You prefer traditional cooking methods
Choose Plant Proteins If:
- You’re environmentally conscious
- You’re watching cholesterol intake
- You want higher fiber intake
- You’re on a budget
The ideal approach for many people in 2025 is a balanced combination of both protein sources, taking advantage of the unique benefits each offers while minimizing their respective drawbacks. Consider your personal health goals, environmental values, and dietary preferences when making your choice.
