| Lipids | Saturated Fats and Unsaturated fats (both fats are long chains of carbon, hydrogen, some oxygen (small amounts) |
| Saturated Fats | Mostly found in animals solid at room temperature High Hydrogen carbon ratio |
| Unsaturated Fats | Mostly in plants, liquid at room temperature. Lower Hydrogen Carbon Ratio |
| Calcium | Body requires it to build, assemble, and maintain our bones and teeth. Example source: milk,cheese |
| Iodine | Main function is to form hormones produced by the thyroid gland. Example sources: Meat eggs |
| Iron | Body needs it for oxygen transport. Serves as both an electron donor and accepter. Without it our cells would basically shrivel up and die. Example sources: Red meat and Chicken |
| Sodium | Without it we would not have blood pressure, helps in building strong bones, transmitting nerve impulses, and making hormones. Example Sources: Cocoa Powder and Wheat |
