The sweeteners you find in many everyday foods and drinks might be linked to earlier puberty in kids. This is especially true for children with specific genetic predispositions, according to research presented at ENDO 2025.
Aspartame, sucralose, glycyrrhizin, and added sugars showed a connection to a higher risk of early puberty. The more of these sweeteners children consumed,the greater their chances of developing central precocious puberty.
This study is among the first to explore how our modern diets, notably sweetener intake, intersect with genetics and early puberty development. it also sheds light on how these sweeteners might affect boys and girls differently,offering a deeper understanding of individual health risks.
Central precocious puberty, a form of early puberty, is becoming more common. It can lead to emotional difficulties, reduced adult height, and an increased risk of future metabolic and reproductive health issues.
Previous work by Dr. Yang-Ching Chen suggests some sweeteners can directly influence hormones and gut bacteria tied to puberty. As a notable example, acesulfame potassium (AceK) may trigger puberty-related hormones by activating “sweet taste” pathways in the brain and increasing stress molecules.
Glycyrrhizin, found in licorice, has been shown to alter gut bacteria balance and decrease the activity of genes crucial for puberty onset. This highlights how much what children consume can impact their development.
The latest findings stem from the taiwan Pubertal Longitudinal Study, which analyzed data from 1,407 teens. researchers assessed sweetener intake via questionnaires and urine samples, and quantified genetic predisposition using polygenic risk scores.
Sucralose consumption was associated with increased central precocious puberty risk in boys. In girls, glycyrrhizin, sucralose, and added sugars were linked to a higher risk.
These insights are highly relevant for families, pediatricians, and public health officials.They suggest that dietary choices, particularly regarding sweeteners, could play a meaningful role in children’s developmental pathways.

Sweeteners and Early Puberty: A growing Concern for Children
What are the Links Between Artificial Sweeteners and Puberty?
The timing of puberty is a complex process influenced by genetics, nutrition, and environmental factors. Increasingly, research suggests a potential link between exposure to certain sweeteners, both artificial and natural (in high doses), and the onset of early puberty in children. This isn’t about a single cause, but rather a contributing factor within a larger web of influences. Concerns center around how these substances might disrupt the endocrine system – the body’s hormone regulation network. hormonal disruption is a key area of examination.
Types of Sweeteners Under Scrutiny
Several types of sweeteners are being investigated for their potential impact on pubertal timing. These include:
Artificial Sweeteners: Aspartame, sucralose, saccharin, and acesulfame potassium (Ace-K) are commonly found in diet sodas, sugar-free snacks, and processed foods. Studies suggest these may affect gut microbiota, potentially influencing hormone levels.
High-Fructose Corn Syrup (HFCS): Prevalent in many sweetened beverages and processed foods,HFCS has been linked to insulin resistance and obesity,both of which are risk factors for early puberty.
natural Sweeteners (in excess): While frequently enough perceived as healthier,excessive consumption of even natural sweeteners like honey or maple syrup can contribute to metabolic imbalances that may affect hormonal development. Sugar intake overall is a critical factor.
Sugar Alcohols: Erythritol, xylitol, and sorbitol, often used in “sugar-free” products, are also under investigation for their potential gut microbiome effects.
How Sweeteners Might trigger Early Puberty
The mechanisms by which sweeteners could contribute to early puberty are still being researched, but several theories are emerging:
- Gut Microbiome Disruption: Sweeteners can alter the composition of the gut microbiome – the trillions of bacteria living in our digestive system. A disrupted microbiome can impact hormone metabolism and inflammation, potentially influencing pubertal timing. Research on gut health and puberty is rapidly expanding.
- Insulin Resistance & Metabolic Syndrome: High sugar and HFCS intake can lead to insulin resistance, a condition where the body doesn’t respond effectively to insulin. This can trigger a cascade of hormonal changes, including increased androgen production, which can accelerate puberty. Metabolic health is crucial.
- Endocrine Disrupting Chemicals (EDCs): Some artificial sweeteners may act as edcs,mimicking or interfering with the body’s natural hormones. This interference can disrupt the delicate hormonal balance required for normal pubertal development.
- Leptin Sensitivity: Leptin, a hormone that regulates appetite and energy expenditure, also plays a role in pubertal timing. Sweetener consumption may affect leptin sensitivity, potentially leading to earlier puberty.
Research Findings: What Does the Science Say?
Several studies have explored the link between sweetener consumption and early puberty:
The national Health and Nutrition Examination Survey (NHANES): Data from NHANES has shown a correlation between consumption of sugar-sweetened beverages and earlier onset of puberty in girls.
Animal Studies: Research on rodents has demonstrated that exposure to artificial sweeteners can alter hormone levels and accelerate pubertal development. While animal studies don’t directly translate to humans, they provide valuable insights.
Observational Studies: Observational studies in human populations have suggested a link between high intake of artificially sweetened beverages and earlier breast development in girls.
Longitudinal Studies: ongoing longitudinal studies are tracking children over time to assess the long-term effects of sweetener consumption on pubertal timing and overall health. Childhood obesity is frequently enough a correlating factor in these studies.
Early Puberty: Potential Health Consequences
Early puberty,defined as the onset of puberty before age 8 in girls and age 9 in boys,can have several potential health consequences:
Psychological and Emotional Challenges: Children experiencing early puberty may struggle with emotional maturity and social adjustment.
increased Risk of Chronic Diseases: Early puberty has been linked to an increased risk of obesity,type 2 diabetes,cardiovascular disease,and certain types of cancer later in life.
Shorter Adult Height: Early closure of growth plates can result in a shorter adult height.
Behavioral Issues: Some studies suggest a correlation between early puberty and increased risk-taking behaviors.
Practical Tips for Parents: Reducing Sweetener Exposure
Parents can take several steps to reduce their children’s exposure to potentially harmful sweeteners:
- Read Food Labels Carefully: Become a label detective! Pay attention to the ingredients list and look for hidden sugars and artificial sweeteners.
- Limit sugary Drinks: Replace sodas, juices, and sweetened teas with water, unsweetened sparkling water, or herbal teas.
- Choose Whole, Unprocessed Foods: Focus on a diet rich in fruits, vegetables, whole grains, and lean protein.
- Cook at Home more Often: This gives you greater control over the ingredients used in your meals.
