Nutrition, cancer, and aging

Area of Science:

• Gerontology and Oncology
• Nutritional Science
• Molecular Biology

Background:

• Aging and cancer risk increase in parallel, sharing common pathophysiological mechanisms.
• Nutrition and physical activity are recognized for their roles in delaying aging and preventing cancer.
• Investigating the impact of dietary and lifestyle interventions on both aging and cancer is of significant interest.

Purpose of the Study:

• To compare the effects of various dietary manipulations on aging and cancer.
• To explore the intersection of nutritional strategies, physical activity, and their influence on age-related diseases and cancer.
• To synthesize current understanding of shared mechanisms between aging and cancer.

Main Methods:

• Review and comparison of established dietary strategies (caloric restriction, fiber, fruits, vegetables) in relation to aging and cancer.
• Examination of molecular mechanisms such as oxidative stress, DNA damage, and DNA methylation.
• Inclusion of physical activity as a relevant non-nutritional factor impacting both aging markers and cancer risk.

Main Results:

• Caloric restriction may delay aging and reduce cancer incidence by decreasing oxidative stress and mitogenesis.
• Oxidative DNA damage is implicated in both aging (mitochondria) and cancer (nucleus).
• Dietary folate, DNA methylation, fiber, fruits, vegetables, and phytochemicals show potential in cancer prevention and may delay aging.

Conclusions:

• Dietary interventions and physical activity are crucial for mitigating aging and cancer risks.
• Shared molecular pathways highlight the potential for synergistic effects of lifestyle choices on healthspan and cancer prevention.
• Further research is needed to fully elucidate the impact of these strategies on biological aging and cancer.
