📚 Understanding Saturated vs. Unsaturated Fats
Fats are a crucial part of our diet, providing energy and supporting various bodily functions. However, not all fats are created equal. Saturated and unsaturated fats differ significantly in their chemical structure and their effects on our health. Let's break down the common misconceptions!
Definition of Saturated Fats
Saturated fats are lipids that have single bonds between carbon atoms in their fatty acid chains. This structure allows the fat molecules to pack tightly together, making them solid at room temperature. Think of butter or coconut oil!
Definition of Unsaturated Fats
Unsaturated fats, on the other hand, have one or more double bonds between carbon atoms in their fatty acid chains. These double bonds create kinks in the structure, preventing the molecules from packing tightly, resulting in a liquid state at room temperature. Examples include olive oil and avocado oil.
