Experts warn that carbohydrate-heavy breakfasts and sugary drinks can worsen blood sugar levels for those with prediabetes. Incorporating moderate carbs, protein, fibre, and limiting added sugar may help stabilise glucose and prevent progression to type 2 diabetes.
For people with prediabetes, breakfast can shape how the rest of the morning unfolds. Vietnamese outlet Thanh Nien warned that a familiar meal of noodle soup, porridge, sticky rice or a baguette can still drive blood sugar higher if it is built mostly around starch, while Johns Hopkins Medicine says refined carbohydrates and sugary drinks are among the most common triggers of glucose spikes.
The first mistake is making breakfast almost entirely carbohydrate. A bowl of plain porridge, a serving of sticky rice or a baguette with very little egg, lean meat or vegetables can leave the meal unbalanced, with too much starch and too little protein or fibre. Eating Well, which Thanh Nien cited, says the issue is usually portion size and composition rather than the food itself. A better approach is to keep the carbohydrate portion moderate and add protein-rich foods such as eggs, lean meat or dairy, alongside vegetables.
The second problem is forgetting about what is in the drink. Sweetened coffee, bottled tea, milk-heavy coffee drinks and juice can add a large dose of sugar to a meal that already contains plenty of starch. The CDC lists sugary drinks, caffeine and skipped meals among factors that can push blood sugar higher, while Mayo Clinic Press notes that dehydration and irregular eating can also worsen spikes. For people who want fruit, Cleveland Clinic dietitian Kate Patton, speaking to Eating Well, recommends whole fruit rather than juice.
The third mistake is assuming that foods widely seen as healthy can be eaten without limit. Oats, whole-grain bread and sweet potatoes are better choices than refined starches, but they still affect blood sugar if the portion is too large. Harvard Health says prediabetes is a warning stage that can progress to type 2 diabetes and is also linked with heart disease, which is why balance matters. The most practical breakfast, according to the combined advice from Thanh Nien and US medical sources, is one built around moderate amounts of complex carbohydrate, plus protein, fibre and as little added sugar as possible.
