Stevia is often added to drinks and desserts as an alternative to sugar. We explain where its sweetness comes from and whether it is really beneficial.
What Is Stevia
It is a low-growing South African shrub with thin stems and small oblong leaves that have a pronounced sweetness. Stevia is 250-300 times sweeter than sucrose. It is usually sold in powder or extract form.
Stevia has long been used in traditional medicine. Scientists continue to study its effects on the body, from blood sugar levels to its impact on the vascular system and immunity.
How Is Stevia Beneficial?
Its sweet taste hides a significant health benefit. Its leaves contain substances that improve bodily functions.

Supports Heart And Vascular Health
Studies show that stevia helps the kidneys remove excess sodium from the body, which lowers blood pressure (if it is consistently above normal, there is a risk of heart disease).
Regulates blood sugar levels
Another benefit confirmed by scientists is that stevia helps control blood glucose levels. This is important for people with metabolic disorders.
Supports Normal Weight
Stevia contains virtually no calories and is an excellent substitute for sugar, making it convenient for weight control.
The Harm Of Stevia
Despite the potential benefits, it is important to consider the negative effects. There are cases of individual intolerance to stevia, and the product is incompatible with some medications.
If you have hypotension, you should not consume it often due to its blood pressure-lowering effect.
Stevia and sugar: what is the difference
Here are some significant differences.
Calorie content and glycemic index
Sugar contains 399 kcal per 100 g, while stevia contains almost none.
Sugar has a high glycemic index of 65-70. Stevia has a glycemic index of 0. This means that sugar quickly raises blood glucose levels, causing a significant release of insulin. Stevia does not have this effect (moreover, some studies indicate a possible moderate positive effect on insulin sensitivity).
Impact On Teeth
Sugar is a source of “food” for oral bacteria that cause tooth decay. Stevia is not fermented by them and does not contribute to the formation of acids that destroy enamel. However, some stevia-based products may contain additional ingredients (such as lactose) that are harmful to teeth.
How To Use Stevia Correctly
It is used as a sugar substitute in drinks and dishes. It is best to start with small doses, gradually finding the optimal amount and observing the body’s reaction.
