How freezing bread before eating could benefit your health
November 10, 2026 · by CEO Rafamall
Freezing freshly purchased white bread before eating it can help reduce the rise in blood sugar levels. This process increases resistant starch, which is not fully absorbed and supports digestive health. A 2023 study found that freezing and reheating white bread could reduce its effect on blood sugar levels.
Freezing freshly purchased bread before eating it could help reduce the rise in blood sugar levels associated with consuming white bread, according to a research into how storage and preparation affect the body's response to starch.

"The worst way to eat your bread is to eat it once it is fresh, fresh from the oven, fresh from the bakery," he said.
He explained that white bread is largely made of starch, which undergoes structural changes when frozen.
"When the bread goes into the freezer, the starch tightens back up. When it tightens back up and you toast it and you eat it, it goes into your system and part of the starch that you are going to get is what we call a resistant starch," the chef explained.
Resistant starch is a type of carbohydrate that is not completely broken down and absorbed in the small intestine. Instead, it passes into the large intestine, where gut bacteria ferment it.
According to the chef, this process could also support digestive health by providing food for beneficial bacteria in the gut.
"That resistant starch, our bodies are not able to fully absorb it. So it doesn't add up to the sugar levels in your system. Part of that resistant starch also goes to feed the bacteria we have in our guts," he added.
What does scientific research say?
A 2023 study published in Novelty in Clinical Medicine has also found that freezing and reheating white bread could reduce its effect on blood sugar levels.
The researchers also found that freezing bread for three, five or seven days produced similar reductions in blood glucose levels.
The findings support the suggestion that freezing and reheating bread may influence how the body responds to its starch.
Frequently asked questions
How does freezing bread affect blood sugar?
Freezing bread causes its starch to undergo structural changes, increasing resistant starch, which is not fully absorbed and helps reduce the rise in blood sugar levels.
What is resistant starch?
Resistant starch is a type of carbohydrate that is not completely broken down and absorbed in the small intestine, instead passing into the large intestine where gut bacteria ferment it.
Can freezing bread benefit digestive health?
Yes, the resistant starch created by freezing bread can feed beneficial bacteria in the gut, potentially supporting digestive health.
Does scientific research support this claim?
Yes, a 2023 study published in Novelty in Clinical Medicine found that freezing and reheating white bread could reduce its effect on blood sugar levels.
Is it better to eat fresh bread or frozen and toasted bread?
According to a chef, eating bread fresh from the oven or bakery is the 'worst way,' suggesting freezing and toasting it could be more beneficial for how the body processes its starch.
