Over the next twenty years, the financial burden on the U.S. government to provide quality healthcare to its aging population is expected to rise to $4.2 trillion (U.S. Centers, 2006). One way the U.S. government could reduce the financial impact of this aging demographic is through funding research into the causes of aging such as telomeres. This work presents a method for calculating lifespan based on the rate of telomere shortening.
Flavonoids are natural antioxidants derived from plants and commonly found in foods, such as fruits and vegetables, with the ability to sequester free radicals. Quercetin, part of a subclass of flavonoids called flavonols, has received considerable attention because of its overwhelming presence in foods. Quercetin is believed to protect against several degenerative diseases by preventing lipid peroxidation. However, the degree and method of quercetin's absorption in vivo has yet to be absolutely determined. It is thought that the predominant glucoside form is converted to the aglycone, which is then converted to one of several quercetin metabolites.
