Calories are units that measure the amount of energy provided by food and beverages. Every type of food contains calories, which our bodies use for various functions. Understanding calories helps us make informed choices about what we eat and how much energy we consume.
Calories matter for health because they play a key role in maintaining body weight. Consuming more calories than the body uses can lead to weight gain, while consuming fewer can lead to weight loss. Balancing calorie intake with physical activity is crucial for overall health and well-being.
In the body, calories are used to support essential functions such as breathing, digestion, and physical activity. When we eat, our bodies break down the food into calories, which are then used to fuel our daily activities and keep our organs functioning. The right amount of calories ensures that we have enough energy for both mental and physical tasks.
It's important to note that not all calories are created equal. Different foods provide different nutrients and can affect our health in various ways. Focusing on the quality of calories, not just the quantity, is essential for a balanced diet.
