Fats and Oils in the Diet

Introduction

• Fats and oils are important components of our diet and serve several essential functions in the body.

Energy Source

• Fats and oils provide the body with energy, and they are a more concentrated source of energy compared to carbohydrates.
• For example, vegetable oil contains 3700 kJ per 100g, while bread flour (mostly carbohydrates) contains 1420 kJ per 100g.

Transport and Storage of Vitamins

• Fats and oils are essential for the transport and storage of fat-soluble vitamins in the body.
• Vitamins are divided into two groups: water-soluble (B-complex and C) and fat-soluble (A, D, E, and K).
• Unlike water-soluble vitamins that need regular replacement in the body, fat-soluble vitamins are stored in the liver and fatty tissues and are eliminated more slowly.

Role of Fat-Soluble Vitamins

• Vitamin A: Essential for eye function and keeping the nose and throat moist. Deficiency can lead to night blindness and throat infections.
• Vitamin D: Important for the formation of strong bones and helps in the uptake of calcium. Deficiency can result in weak bones (Rickets).
• Vitamin E: Acts as an antioxidant and protects other vitamins like A and C. Deficiency is rare.
• Vitamin K: Necessary for blood clotting. Its deficiency can lead to excessive bleeding.

Conclusion:

• Fats and oils not only provide energy but also play a vital role in the transport and storage of fat-soluble vitamins in the body.
• Fat-soluble vitamins are stored in the liver and fatty tissues and are important for various bodily functions, including vision, bone health, antioxidant protection, and blood clotting.
