Macronutrients are the cornerstone of nutrition. Understanding how proteins, carbohydrates, and fats work together can transform your approach to healthy eating.
What Are Macronutrients?
Macronutrients are nutrients your body needs in large amounts to function properly. They provide energy (calories) and serve essential functions in your body.
Proteins: The Building Blocks
Proteins are essential for building and repairing tissues, making enzymes and hormones, and supporting immune function. Each gram provides 4 calories.
- Complete proteins contain all essential amino acids (meat, fish, eggs, dairy)
- Incomplete proteins lack some amino acids (most plant-based sources)
- Recommended intake: 0.8-1.2g per kg of body weight
Carbohydrates: Your Primary Energy Source
Carbohydrates are your body's preferred energy source, especially for your brain and during exercise. Each gram provides 4 calories.
- Simple carbs: Quick energy (fruits, honey, sugar)
- Complex carbs: Sustained energy (whole grains, vegetables, legumes)
- Fiber: Non-digestible carbs that support digestive health
Fats: Essential for Health
Fats support cell growth, protect organs, and help absorb vitamins. Each gram provides 9 calories.
- Saturated fats: Found in animal products and tropical oils
- Unsaturated fats: Found in nuts, seeds, fish, and plant oils
- Trans fats: Artificial fats to avoid
