How Safe Is Your Sweetener?

As concerns about sugar consumption and its potential health risks continue to grow, more and more people are turning to alternative sweeteners as a means to satisfy their sweet tooth without worry. These sugar substitutes promise sweet flavors without the calories or detrimental effects on blood sugar levels, making them an attractive option for those seeking to manage their weight or regulate their sugar intake. However, as the popularity of alternative sweeteners surges, it becomes essential to delve into the safety aspects associated with their consumption.

In this article, we dive into the safety considerations around alternative sweeteners, separating fact from fiction and shedding light on their potential risks and benefits. 

Let’s dive in. 

Sucralose

Sucralose is a zero-calorie artificial sweetener that is made from sugar and used as a sugar substitute in a wide range of food and beverage products. It is commonly marketed under the brand name Splenda®. 

The safety of sucralose has been extensively studied and evaluated by various regulatory agencies in the US and around the world.
