What is the Nutrition of Fat?
Fat is a vital nutrient providing energy, supporting cell growth, and aiding nutrient absorption. It's crucial for building cell membranes, nerve tissue (including the brain), and hormones. However, not all fats are created equal; some are healthier than others.
- Energy Source: Fats are a concentrated source of energy, providing more than double the calories per gram compared to carbohydrates or protein.
- Structural Component: Fats are essential building blocks for cell membranes and nerve tissue, including the brain.
- Hormone Production: The body uses fats to synthesize various hormones crucial for numerous bodily functions.
- Nutrient Absorption: Fats help the body absorb fat-soluble vitamins (A, D, E, and K).
- Organ Protection: Fat cushions and protects vital organs.
- Cholesterol and Blood Pressure Regulation: Certain types of fat contribute to healthy cholesterol levels and blood pressure.
Types of Fats and Their Sources
The types of fat you consume significantly impact your health. There are three main types:
-
Saturated Fats: Found in higher amounts in animal products (fatty cuts of meat, meat products, butter, lard, cheese), these should be limited in your diet as excessive intake can negatively affect heart health. [Source: NHS]

- Monounsaturated Fats: Found in olive oil, avocados, nuts, and seeds.
- Polyunsaturated Fats: Found in vegetable oils (sunflower, corn, soybean, flaxseed), walnuts, flax seeds, and fish. [Source: Harvard Health, Nutrition Source]
