what it claims

The toxicity of aspartame depends solely on the dose: at current consumption levels, which are well below the daily safety limit of approximately 40 to 50 mg/kg of body weight, beverages containing this sweetener are safe for health.

The principle that the dose makes the poison is scientifically robust and applies to all foods.

The principle that the dose makes the poison is scientifically robust and applies to all foods. The World Health Organization (WHO) and JECFA, relying on systematic reviews of clinical and observational data, reaffirmed in 2023 that aspartame consumption of less than 40 mg per kilogram of body weight per day is completely safe. For a 70 kg adult, this is equivalent to a maximum of 2,800 mg of aspartame per day. However, the creator's estimate suggesting a risk threshold at 60 or 90 cans is exaggerated. With a typical diet beverage can containing about 180 mg of aspartame, the official safety limit is actually around 15 to 20 cans daily for an average adult. Although aspartame is subject to discussion regarding its long-term effects, expert consensus confirms that common moderate consumption presents no risk to well-being.

What the graded evidence says

Effect: body weight (RCTs, sweetener replacing sugar) vs long-term outcomes (WHO systematic review) — small average weight reduction (~1 kg) when swapping sugar for sweeteners in short-term RCTs; no sustained body-fat benefit long term, with observational associations to higher T2D and CVD risk
Measured on: adults and children; general population

The short-term weight edge is real but small; the long-term concerns (T2D, cardiovascular) are observational and can't prove cause. The aspartame 'possible carcinogen' label reflects limited evidence at very high exposure, not everyday-can risk. Reasonable people can disagree, hence WHO's recommendation is conditional.
