Exploring the intersection of diet and cancer prevention, recent research highlights how certain eating patterns, notably calorie restriction (CR) and fasting, may mitigate cancer risks. These dietary strategies have demonstrated promising results in enhancing lifespan and healthspan in rodents by manipulating key hormonal pathways. Central to these benefits is the reduction of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) activity, which are pivotal in the aging and development of cancer.

Intermittent fasting (IF), periodic fasting (PF), and fasting-mimicking diets (FMDs) are particularly effective in these hormonal modulations. The nuanced approach of alternating between low and normal hormone levels appears optimal for promoting longevity and maintaining physiological function. This adaptability in dietary regimen offers a potential blueprint for not just cancer prevention but also for the broader management of age-related disorders.

The research furthers our understanding of how dietary choices influence cancer biology through hormonal pathways, suggesting a proactive approach to disease prevention through manageable lifestyle changes. It underscores the role of nutrition in not just maintaining general health but also in configuring our body’s hormonal environment to stave off diseases like cancer, emphasizing the need for further human studies to translate these findings into practical dietary guidelines.
