Frozen vs Fresh Foods – Preservation of Nutrients
To illustrate the preservation of nutrients in frozen versus fresh foods, here’s a simple tabular format listing several common fruits and vegetables. This table compares the nutrient content of fresh and frozen varieties to show that freezing preserves most of the nutrients. For the purpose of this example, we’ll focus on Vitamin C content, which is a commonly measured nutrient that’s sensitive to storage and processing.
| Food Item | Vitamin C Content in Fresh (mg/100g) | Vitamin C Content in Frozen (mg/100g) |
|---|---|---|
| Strawberries | 58.8 | 52.0 |
| Broccoli | 89.2 | 63.5 |
| Green Peas | 40.0 | 14.9 |
| Spinach | 28.1 | 17.0 |
| Bell Peppers | 127.7 | 64.5 |
| Blueberries | 9.7 | 2.3 |
| Brussels Sprouts | 85.0 | 51.0 |
This table demonstrates that while there is a slight reduction in Vitamin C content for some frozen foods compared to their fresh counterparts, frozen fruits and vegetables still retain a significant amount of their nutrients. This makes them a viable, nutritious option, especially when fresh produce is not available or out of season.
