Drinking diet sodas is safe for your health: for an 80 kg person, one would need to consume more than 20 cans per day to reach the acceptable daily intake for aspartame set by health authorities, and risks regarding vitality degradation or weight gain are scientifically unfounded at usual consumption levels.

Jeff Nippard's assertion that the margin of safety for diet sodas is immense is solid and well-supported by science. An in-depth toxicological and epidemiological assessment conducted by Magnuson et al. (2007) [PMID: 17828671] confirms that aspartame is safe at realistic human consumption levels. Regarding vitality and overall health, a large prospective cohort study (Lim et al., 2006) [PMID: 16985027] involving over 470,000 people revealed no link to major health impairments, which is corroborated by an observational case-control study (Bosetti et al., 2009) [PMID: 19661082]. Furthermore, a vast meta-analysis of randomized controlled trials and observational studies by Toews et al. (2019) [PMID: 30602577] confirms the absence of major deleterious effects while noting that direct benefits on weight management remain modest. Although the safety of these drinks at normal doses is validated by this robust evidence, future research is still needed to clarify their potential long-term impact on gut flora or satiety signaling. In sum, aspartame is not the disruptor often described, and the margin before reaching a problematic threshold is gigantic.
