Vitamin C in health and disease: a current perspective
Celis-Morales, Carlos [Univ Mayor, CIFE, Santiago, Chile]
Vitamin C is a well-known antioxidant. Its intake has been associated with a number of benefits, some of which lack a scientific basis. This review summarizes important biological aspects that determine vitamin C homeostasis, discusses the available information on its possible beneficial effects and its intake in various countries, with special emphasis on some risk groups. The beneficial effects of this vitamin in inflammation, cancer and cardiovascular disease are also summarized, as well as its role as immuno-modulator and epigenetic regulator. Dietary sources of vitamin C and the factors that influence its stability are also presented. Finally, an overview of the research conducted on healthy lifestyles in Latin-American countries are presented. This research summarized provides evidence of poor eating habits, which could account for a vitamin C hypovitaminosis not yet reported that could be associated with unhealthy ageing and the development of non-transmissible chronic diseases.
