Calories are the unit of measurement for the energy our bodies use to function. However, the source of these calories is as important as their quantity. Macronutrients are the nutrients that provide calories: proteins, carbohydrates, and fats. Protein (4 calories per gram) is essential for building and repairing tissues. Carbohydrates (4 calories per gram) are the body's primary source of energy. Fats (9 calories per gram) provide long-term energy and support cellular function.
On the other hand, phytonutrients, although they do not contain calories, are beneficial compounds found in plants. They play a crucial role in protecting health, supporting the body's antioxidant and anti-inflammatory defenses.
By understanding these differences, you can better adjust your diet to meet your health and weight goals.
