7 ‘Healthy’ Foods That Secretly Spike Your Blood Sugar, Experts Warn
Experts such as Prof. Dr. Stephan Martin and metabolism researcher Stefan Kabisch from Charité Universitätsmedizin Berlin warn that certain foods can trigger unexpected blood sugar spikes. Oats, for example, often cause higher glucose levels than many realise, even when chosen in high-fibre, no-sugar-added varieties. Similarly, fruits—while nutritious—contain natural glucose that can affect insulin response.
The findings highlight how some so-called healthy foods can influence blood sugar in ways many people overlook. Nutritionists recommend checking ingredient lists and opting for whole, minimally processed whole foods where possible. Awareness of these hidden triggers can help individuals make more informed dietary choices.
