Key Terms Explained
| Term | Explanation | Why it matters here |
|---|---|---|
| Maillard Reaction | This is the chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor. Think of the browning on bread or meat. | The Maillard reaction contributes to the rich, complex flavor of the brownies as they bake. |
| Glycemic Index (GI) | The Glycemic Index measures how quickly a food raises blood sugar levels. High GI foods cause a rapid spike, while low GI foods are digested more slowly. | These brownies likely have a high GI due to the sugar content. Consider pairing them with a source of protein or fiber to slow down digestion. |
| De Novo Lipogenesis | This is the process where your body converts excess carbohydrates into fatty acids, which are then stored as fat. It’s not the most efficient pathway, but it happens. | Overeating high-sugar foods like these brownies can contribute to *de novo* lipogenesis if your overall calorie intake exceeds your needs. |
