This is an important stage to adjust diet and lifestyle, because good blood sugar control can help reduce the risk of developing type 2 diabetes.
In the diet of people with pre-diabetes, white bread is a food that should be restricted, especially when eaten in large quantities or regularly.
The first reason lies in the ingredients of white bread. White bread is mainly made from refined flour, during processing, most of the bran and germs rich in fiber are removed. Therefore, this type of bread usually contains less fiber than products made from whole grains. Fiber plays a role in slowing down the digestion and absorption of carbohydrates, thereby helping blood sugar increase more slowly after meals.
In addition, white bread can make blood sugar increase relatively quickly because refined carbohydrates are broken down by the body into glucose. For people with pre-diabetes, insulin resistance makes it more difficult for the body to deliver glucose from the blood into cells.
A meal containing a lot of refined carbohydrates can therefore cause a significant increase in blood sugar, creating more pressure on the glucose control process.
However, this does not mean that prediabetes patients must completely eliminate white bread. It is important to control portion sizes and food combinations.
Instead of eating a lot of white bread individually, you can choose whole wheat bread or whole grain bread, and combine it with protein sources such as eggs, fish, lean meat and fiber-rich vegetables. This way of eating helps the meal be more balanced and can limit post-eating blood sugar spikes.
Pre-diabetic people should limit white bread mainly because this is a refined carbohydrate source, low in fiber and can cause blood sugar to rise faster than choices rich in whole grains.
Changing the type of bread, controlling portion sizes, and building a balanced meal are practical steps to support blood sugar control and long-term metabolic health.
