Hidden sugars in 'healthy' foods may spike your blood glucose

Many foods marketed as healthy can unexpectedly raise blood sugar levels. Items like granola, yogurt, and smoothies often contain hidden sugars that cause unexpected spikes. Experts now advise checking labels carefully to avoid these risks.

Some popular 'healthy' foods carry surprising risks for blood glucose. Sushi, for example, can trigger sharp increases due to its rice content. Rice cakes, often seen as a light snack, have a high glycemic index, leading to rapid glucose rises.

Smoothies and protein shakes may also cause problems when multiple carbohydrate sources are mixed together. Even oatmeal, usually considered a safe option, can raise blood sugar more than expected—especially if extra fibre doesn't balance it out.

Protein bars sometimes contain hidden sugars while lacking enough protein to stabilise glucose. Plant-based milks, particularly oat and rice varieties, can also add unwanted sugars. High-carb sauces and dressings often include added sugars, pushing their glycemic index higher than anticipated.

To avoid blood sugar spikes, reading both total sugar and added sugar content is essential. Many foods marketed as healthy still pose risks if their ingredients aren't checked. Making informed choices can help maintain steadier glucose levels.
