According to the World Health Organization, millions of people fall ill or die each year due to a lack of safe and nutritious food. This stark reality underscores a fundamental truth: food is a basic necessity for life, not a luxury. But why is food necessary for humans at a cellular level, and what critical roles does it play in our daily existence and long-term health?

Did you know that the human brain alone consumes about 20% of the body's total energy, despite making up only 2% of the body's weight? This massive energy expenditure is a primary reason why human beings need food, as it provides the essential fuel and nutrients required for every bodily process, from thinking to breathing and tissue repair.

According to the World Health Organization, malnutrition is the single gravest threat to global public health, raising the critical question: **do we really need to eat food** for survival? The answer is an unequivocal yes, as the body relies on a constant intake of essential nutrients to fuel its most basic functions.
