Artificial sweeteners may accelerate puberty in children, study warns

  • A Taiwanese study found that artificial sweeteners (e.g., aspartame, sucralose, glycyrrhizin) may disrupt normal development, accelerating puberty in children. Central precocious puberty (CPP) was observed in 481 of 1,407 adolescents studied.
  • Early puberty increases risks of emotional distress (e.g., anxiety, depression), metabolic disorders (obesity, diabetes), reproductive issues and shorter adult height due to hormonal imbalances.
  • Girls face broader risks from multiple sweeteners (glycyrrhizin, sucralose, added sugars), while boys are most affected by sucralose, suggesting girls' hormonal systems may be more vulnerable.
  • Children with certain genetic predispositions (identified via 19 puberty-related genes) are at higher risk, with even moderate sweetener exposure potentially triggering early puberty.
  • Despite rising CPP cases, warnings about sweeteners are rare. Parents are urged to avoid processed foods, read labels and prioritize whole foods. Researchers demand stricter regulation and transparency from the food industry.
Parents who swap sugary sodas for diet drinks and sugar-free snacks in hopes of making healthier choices may inadvertently be speeding up their children's puberty, according to groundbreaking research from Taiwan. A study led by Dr. Yang-Ching Chen at Taipei Medical University has uncovered alarming evidence that artificial sweeteners – including aspartame, sucralose and even natural compounds like glycyrrhizin – are disrupting normal developmental timelines, pushing children into early puberty with potentially lifelong consequences. The study, one of the largest of its kind, examined 1,407 adolescents and found that 481 had developed central precocious puberty (CPP), a condition where puberty begins abnormally early. The findings, presented at ENDO 2025, the Endocrine Society's annual meeting, suggest that what children consume – especially products marketed as "healthy" alternatives – may be hijacking their hormonal systems.

The hidden culprits in "healthy" foods

Artificial sweeteners, long touted as safe sugar substitutes, are now under scrutiny for their role in early puberty. The study identified key offenders such as aspartame, commonly found in diet sodas and sugar-free gum; sucralose (Splenda), prevalent in cereals and protein bars; and glycyrrhizin, a natural sweetener derived from licorice. These chemicals do more than trick taste buds –  they alter brain chemistry and hormone regulation at a cellular level. Acesulfame potassium (Ace-K), another common artificial sweetener, was found to activate brain receptors that prematurely trigger puberty hormones while flooding the body with stress molecules.

A lifelong health crisis in the making

Early puberty isn't just about physical changes – it sets off a cascade of health risks. Children who mature too early often face emotional trauma, including bullying, anxiety and depression. A type of early puberty known as central precocious puberty is becoming increasingly common. It can lead to emotional distress, shorter adult height and increased risk of future metabolic and reproductive disorders. Metabolic disorders such as obesity, diabetes and heart disease become more likely later in life, and hormonal imbalances may even affect fertility. Chen's previous research revealed that sweeteners don't just pass harmlessly through the body – they rewire biological pathways, altering gut bacteria and silencing genes that regulate normal development.

Gender and genetic predisposition

The study uncovered disturbing gender disparities in how artificial sweeteners affect children. Boys were most impacted by sucralose, commonly found in processed snacks, while girls faced a broader assault – glycyrrhizin, sucralose and added sugars all increased their risk. This suggests that girls' hormone systems may be more vulnerable to dietary disruptions, raising urgent questions about food industry marketing tactics targeting young consumers. Some children are genetically more susceptible to the effects of artificial sweeteners. Researchers used polygenic risk scores – based on 19 puberty-related genes – to identify kids at higher risk. For them, even moderate sweetener exposure could trigger developmental chaos. "This is one of the first studies linking modern diets to genetic risk factors for early puberty," Chen noted. "It's not just about calories – it's about chemicals interfering with biology."

The medical establishment's dangerous silence

Despite rising global rates of CPP, pediatricians rarely warn parents about the risks of artificial sweeteners. Food companies continue marketing these products as "safe," while regulatory agencies lag behind the science. Chen urged immediate action, stating, "Screening for genetic risk and reducing sweetener intake could prevent long-term harm." Yet, few doctors are actively advising this precaution. While policymakers debate, families can take protective steps. Reading every label is crucial, as sweeteners hide in seemingly healthy products like yogurts, protein bars and flavored waters. Opting for whole foods – fresh fruits, vegetables and organic proteins – supports natural development. Additionally, antioxidant-rich foods, clean water and reduced processed food intake can help mitigate potential damage. This study isn't just about puberty – it's about how modern food additives are rewriting human biology. Parents deserve transparency, regulators must reassess safety claims and the medical community must sound the alarm. The era of assuming artificial sweeteners are harmless is over. The evidence is clear: What children consume today shapes their health for decades to come. Watch this video to learn about the dangers of aspartame.
