Bread is one of the most consumed foods in the world, but the way it is stored and prepared can influence its nutritional composition. For years, experts have warned of the negative effects of storing bread in the refrigerator, as this process alters its texture and accelerates its degradation. However, recent studies suggest that frozen bread may not only preserve it better, but also make it healthier.
Freezing the bread changes its structure?
According to an investigation published in the the way bread is stored and prepared can affect the glycemic answer of the body after its consumption.
Research analyzed as different methods of conservation and preparation influence the conversion of starches to sugar in the human body.
For the study, scientists recruited 10 healthy participants To test the effect of four distinct forms of white bread consumption:
- Fresh bread;
- Frozen bread and then thawed;
- Toasted bread;
- Toasted bread after being frozen and thawed.
The results indicated that The impact on blood sugar levels is reduced when bread is frozen and then thawed.
The same effect was observed when toasting the bread, highlighting the greater reduction in glycemic response when bread was first frozen and then toasted.
What is the impact on the glycemic index?
O glycemic index (IG) measures the speed with which a food increases blood sugar levels, on a scale of 0 a 100.
High GI foods cause rapid glucose peaks, which may increase the risk of insulin resistance and type 2 diabetes.
We recommend:
According to the study, Frozen bread and then thawed reduces starch digestion rate, providing a more balanced glycemic response.
This means that the organism absorbs sugars slower, avoiding blood glucose peaks.
In addition to metabolic benefits, freezing bread can be an effective strategy for reduce food wastesince it allows to conserve food longer, preventing it from deteriorating quickly.
Freezing or eating fresh: What is the best option?
Experts conclude that, from the health point of viewFreezing bread before consuming it can be a more beneficial option, especially for those who want to control blood sugar levels.
Furthermore, toast the bread after frozening intensifies this effectbecoming an interesting choice for those looking for a balanced diet.
On the other hand, fresh bread remains a tasty and nutritious option, especially if it is full cereals and little processed.
The best choice will therefore depend on the objectives and needs of each consumer.
