The role of biofactors in the prevention and treatment of age‐related diseases

The present demographic changes toward an aging society caused a rise in the number of senior citizens and the incidence and burden of age‐related diseases (such as cardiovascular diseases [CVD], cancer, nonalcoholic fatty liver disease [NAFLD], diabetes mellitus, and dementia), of which nearly half is attributable to the population ≥60 years of age. Deficiencies in individual nutrients have been associated with increased risks for age‐related diseases and high intakes and/or blood concentrations with risk reduction. Nutrition in general and the dietary intake of essential and nonessential biofactors is a major determinant of human health, the risk to develop age‐related diseases, and ultimately of mortality in the older population. These biofactors can be a cost‐effective strategy to prevent or, in some cases, even treat age‐related diseases. Examples reviewed herein include omega‐3 fatty acids and dietary fiber for the prevention of CVD, α‐tocopherol (vitamin E) for the treatment of biopsy‐proven nonalcoholic steatohepatitis, vitamin D for the prevention of neurodegenerative diseases, thiamine and α‐lipoic acid for the treatment of diabetic neuropathy, and the role of folate in cancer epigenetics. This list of potentially helpful biofactors in the prevention and treatment of age‐related diseases, however, is not exhaustive and many more examples exist. Furthermore, since there is currently no generally accepted definition of the term biofactors, we here propose a definition that, when adopted by scientists, will enable a harmonization and consistent use of the term in the scientific literature.
