Essential vitamins are indispensable because they sustain life, prevent disease, and ensure the body’s systems function effectively.

Fats are vital for energy, hormone production, vitamin absorption, and cell structure. They protect organs, regulate body temperature, and enhance food flavor and satiety. Essential fatty acids like omega-3 and omega-6 must come from the diet, supporting critical functions. A balanced intake of healthy fats supports growth, development, and overall health, making fats crucial beyond just being a calorie source.
