Experts indicate that artificial sweeteners are in more than 23,000 food or drink products worldwide. Many people use them in their coffee, tea, and other drinks instead of sugar.

A food label won’t usually clearly state that it contains these additives, so it’s essential to know how to look for them. The food label might even say that it has no added sugars, but that’s because they don’t include artificial sweeteners in that statement. Some of the popular artificial sweeteners include the following names:

  • Aspartame: This sweetener sells under the names NutraSweet or Equal. It is much sweeter than refined sugar but not much healthier as it poses health risks.
  • Acesulfame potassium: This sweetener is sometimes called acesulfame K and used for cooking and baking. You might recognize it by the brands Sunset or Sweet One.
  • Sucralose: This sweetener is about 600 times sweeter than table sugar and gets used for baking and cooking. The brand name is Splenda, which is commonly used for sweetening drinks.
  • Saccharin: While this sweetener is much sweeter than refined sugar, it’s not a healthier option. The brand names include Sweet’N Low, Sweet Twin, and Necta Sweet.
  • Neotame: This sweetener often gets used for cooking and baking, so you’ll often find it in processed baked goods. It sells under the brand name Newtame.

How Artificial Sweeteners Can Raise Risk of Heart Attack

With cardiovascular disease being the leading cause of death, it’s essential not to ignore the risks. The World Health Organization notes an association between drinks containing artificial sweeteners and heart disease.
