Breakfast cereal is a popular choice for breakfast for housewives' families because of its convenience and attractive flavor. However, many types of grains today contain very high levels of added sugar, which negatively affects health, especially blood sugar levels.
According to the World Health Organization, a diet high in added sugars is closely linked to the risk of type 2 diabetes and obesity. In particular, breakfast cereals - which are advertised as healthy - are one of the main culprits if not chosen carefully.
Research shows that many breakfast cereals can contain 10-20 grams of sugar per serving - equivalent to 2-5 teaspoons of sugar.
When you consume these simple sugar-rich foods, your body will quickly absorb and metabolize them, causing blood sugar to rise rapidly. This is because simple sugar has a very high glycemic index, leading to the phenomenon of "peak blood sugar" - that is, blood glucose levels spike after eating.
Foods with a high glycemic index not only cause strong fluctuations in blood sugar but also increase hunger after a few hours, making it easier for consumers to eat more and difficult to control their weight. This creates an unfavorable loop: blood sugar increases, insulin increases, then blood sugar drops rapidly, causing hunger and continuing to eat more sugar.
Nutritionists also warn that children and adolescents are the most vulnerable to the trend of consuming high-sugar breakfast cereals every day. They recommend that parents should choose grains with little or no sugar, and combine them with fiber (such as whole grain oats) and protein to slow down the absorption of sugar, thereby controlling blood sugar more effectively.
