1. French Toast and Blood Sugar
French toast is a dish made by soaking bread in an egg mixture (eggs, milk, sugar, etc.) and then pan-frying it with butter. Its effect on blood sugar and health depends on the type of bread used, the ingredients of the egg mixture, and the cooking method.
2. Bread Condition and Absorption Rate
– Freshly Baked Bread: Soft, moist, freshly baked bread acts like a sponge, absorbing liquids very quickly and in large amounts.
– Day-Old Bread: Bread that is a day old, with some moisture evaporated and a slightly firm texture, has a denser structure, which reduces the speed and amount of liquid it can absorb.
– The Result: Therefore, even if soaked in the same egg mixture for the same amount of time, a slightly stale bread will absorb less of the mixture than a soft, fresh bread.
3. Effect on Health
– Calorie Reduction: The egg mixture contains calorie-bearing ingredients like eggs, milk, and butter. If the bread absorbs less of this mixture, you can, to a minor extent, reduce the total amount of calories and fat you consume.
– Blood Sugar Impact: Of course, this method does not dramatically change the glycemic response. More important factors for the blood sugar impact of French toast are the ‘type of bread (white vs. whole wheat),’ ‘whether sugar is added to the egg mixture,’ and ‘the syrup or fruit served with it.’
– Culinary Advantage: From a cooking perspective, slightly stale bread has the advantage of holding its shape better without becoming too soggy in the egg mixture.
Summary: Using slightly stale bread when making French toast can result in the bread absorbing less of the egg mixture, thereby slightly reducing the overall calories and fat of the dish. This can be a small but meaningful tip for blood sugar management.
