[HIGHLIGHTS] A dietitian checked: which is less harmful - Diet Coke or Coke Zero?

Diet Coke and Coke Zero contain aspartame, caffeine, natural flavors and caramel colors. Aspartame is about 200 times sweeter than sugar.

Coke Zero also contains a sweetener called acesulfame potassium or Ace-K. A can of Diet Coke contains about 46 milligrams of caffeine, while Coke Zero contains 34 milligram of caffeine. The FDA recommends that the daily intake for as partame does not exceed 50 milligraphicrams per kilogram of body weight every day. The World Health Organization's cancer research arm classified aspartAME as a "probable carcinogen," and called for further research into potential health risks.. Another dietitian warns surfers against excessive consumption of artificial sweeteners, which she says can cause the body to crave sweets. The FDA defines it as a food additive, and emphasizes that this determination is based on a review of more than 90 studies on the substance's possible toxic effects.. A dietician with almost 800,000 followers on TikTok, Abby Sharp, says self-discipline is the most important key.
