Sugar has caught a bad name for itself, and rightfully so. According to Dt. Deepti Lokeshappa, Senior Consultant, Nutritionist, and Dietitian, Motherhood Hospital, Bengaluru, “Sugar has caught a bad name for several reasons, primarily due to its potential negative effects on health and well-being. Some of the key reasons sugar has a negative reputation include various health problems like type 2 diabetes, heart disease, and dental issues; blood sugar spikes and crashes in blood sugar levels, leading to feelings of fatigue; dental problems like tooth decay and cavities; addiction to sugar etc.
Most people are trying to avoid artificial sugar and are looking for natural sweeteners. Stevia is one of the leading names in the natural sweetener category. But you must watch out for the side effects of Stevia. The leaves of the stevia plant are uniquely sweet, but its chemicals also react with many things in your diet. Many companies also mix Stevia with artificial sweeteners, which can harm the body.
Sharing the difference between natural and artificial sweeteners, our contributor Mary Sabat, RDN, LD, and Ace Certified Trainer, says, “Natural sweeteners, like stevia, are derived from plants or other natural sources and typically contain fewer calories than sugar. They are considered more “natural” because they undergo minimal processing. In contrast, artificial sweeteners, such as aspartame, saccharin, and sucralose, are synthetic compounds created in a lab. They are often much sweeter than sugar and contain few to no calories, making them a popular choice for those seeking to reduce calorie intake. While both types of sweeteners can be used as sugar substitutes, artificial sweeteners are highly processed and may have a different taste profile, while natural sweeteners may retain some of the nutrients present in their source ingredients.”

While Stevia extract is a miracle find, it must be used with caution. People who are already on medication for diabetes or have a tendency to hypoglycemia may not use it at all. The side effects of Stevia are mainly focused on the interaction with medication. Some studies talk about blood clots due to the consumption of Stevia. But, this study used a plant with a slightly different composition. Stevia is a nonnutritive sweetener and its marketed version, Metabolite Steviol, reduces sugar spikes in the body. If you want to use this sweetener in your food, use a potted plant instead of the products sold over the counter. You should also consult with your doctor before starting it.
