Which food is classified as a simple carbohydrate?

Cakes are categorized as simple carbohydrates primarily because they often contain refined sugars and flours, which are processed quickly by the body, leading to rapid spikes in blood glucose levels. Simple carbohydrates consist of sugars that provide quick energy, and items like cakes are high in these sugars. They are typically low in fiber and nutritional density, which distinguishes them from other carbohydrate sources.

Fruits, while rich in natural sugars and also classified as simple carbohydrates, contain essential vitamins, minerals, and fiber, which help regulate digestion and provide a more sustained energy release. Vegetables generally have more complex carbohydrates and fiber, resulting in slower digestion and energy release. Whole grain pastas are a source of complex carbohydrates, providing longer-term energy due to their higher fiber content.

Thus, cakes exemplify simple carbohydrates due to their composition and the way they affect blood sugar levels compared to other food options listed.
