Calories: The Life Force Inside Your Plate – Explained by NewsWebFit
Imagine this:
You're eating a juicy mango under the summer sun. It's sweet, refreshing—and
loaded with something invisible yet powerful. A mango isn’t just fruit—it’s
fuel. That invisible energy? Calories.
Welcome to NewsWebFit, where we uncover what calories really mean, why
they matter, and how they shape your health, organs, and life.
🌿 What Are Calories?
Calories are units of energy. Specifically, 1
calorie (cal) is the amount of energy required to raise the temperature of
1 gram of water by 1°C.
But in food science, we deal with kilocalories (kcal) – 1 kcal = 1,000
calories.
When we say a banana has 89 kcal, it means your body gets 89 units of energy to perform daily activities: breathing, thinking, running, healing.
🧪 How Are Calories Measured?
Food calories are measured using a bomb calorimeter,
where food is burned in a sealed chamber surrounded by water. The heat released
tells us how much energy the food contains.
Modern methods now use macronutrient estimation:
- Carbohydrate:
4 kcal/gram
- Protein:
4 kcal/gram
- Fat:
9 kcal/gram
- Alcohol: 7 kcal/gram
🧠 What Do Calories Do in the Human Body?
✅ Function of Calories:
- Energy
for cells & organs
- Muscle
movement
- Brain
function & memory
- Digestion
- Hormone
production
- Healing
& immunity
- Thermoregulation (body temperature)
🧍♂️🧍♀️ The Connection: Human + Food + Calories
Every individual needs calories, but not equally.
Caloric needs depend on:
- Age
- Sex
- Body
size
- Metabolism
- Physical
activity
Too many = fat storage & disease.
