Answer: Aspartame is keto-friendly, but better sugar-alternatives are available.
Aspartame is one of the most prevalent artificial sweeteners in the US when it comes to low-calorie foods.
A packet of an aspartame-based sweetener like Equal contains only 0.9 g of net carbs and less than one calorie. Because of this, food manufacturers add aspartame to many sugar-free products, including Diet Coke, Orbit gum, and Jell-O instant sugar-free pudding.
The hype around aspartame isn’t all positive, and one popular fear is that aspartame causes cancer. An Italian study of the effects of aspartame on rats suggested a possible link between the sweetener and an increased risk for blood-related cancers, but later studies on humans contradicted those results. Ultimately, the FDA found that it’s safe to use aspartame in foods and beverages. The FDA does warn that a minority of people with a rare hereditary disease called phenylketonuria (PKU) should avoid aspartame as they can’t metabolize it.
