🥖 Fresh vs. Commercial Bread: The Health Impact
LIP #148
Jul 16, 2025
🚫 Commercial Bread Problems:
- Calcium propionate (mold inhibitor)
- High fructose corn syrup (diabetes risk)
- 3x more yeast than traditional bread
- Causes glucose spikes affecting sleep
✅ Fresh Bread Benefits:
- Sourdough fermentation: 10% starter, 90% flour
- Natural beneficial bacteria
- No preservatives needed
- Better glucose response
📊 Health Impact:
- White bread: Converts almost entirely to sugar
- Whole wheat: Fiber slows sugar absorption
- Quality bread: Normal glucose oscillations
🥖 Pro Tip: French bakeries use sourdough starter for all bread types - they just don't call it "sourdough." Prioritize fresh bread first, then upgrade flour quality when possible.
