Dietary antioxidant link to cervical cancer risk

Researchers in the United States have identified a link between dietary antioxidant intake and a lower prevalence of cervical cancer. Using a composite antioxidant dietary index to measure overall nutrient intake rather than single food items, the study found an inverse association between high antioxidant scores and cervical cancer diagnoses among adult women.

While the study noted that risk factors such as smoking, obesity, and living alone were more frequent among those with a history of the disease, researchers clarified that the findings do not imply specific foods directly prevent cancer. Instead, the data suggests a connection between nutrition, immune function, and cellular health. This is particularly relevant as most cervical cancer cases are linked to persistent high-risk human papillomavirus (HPV) infections, prompting further investigation into how antioxidants might influence cellular changes following such infections.

Newer research published in the International Journal of Gynecology & Obstetrics, utilizing data from the US-based NHANES survey, has provided more specific details regarding these nutritional correlations. Analyzing 1,044 women, researchers determined that those with the highest intake of antioxidants—specifically vitamins A, C, and E, zinc, selenium, and carotenoids—had approximately 56% lower odds of reporting a history of cervical cancer. This correlation remained consistent after accounting for variables such as age, income, smoking, alcohol consumption, and BMI.

In addition to dietary strategies, health data from the global alliance Gavi emphasizes the importance of early HPV vaccination. The vaccine can prevent up to 90% of cervical cancers, with the greatest benefits observed when administered to adolescents aged 9 to 14 to ensure a strong immune response before potential viral exposure.
