The rise of life expectancy in current societies is not accompanied, to date, by a similar increase in healthspan, which represents a great socio-economic problem. It has been suggested that aging can be manipulated and then, the onset of all age-associated chronic disorders can be delayed because these pathologies share age as primary underlying risk factor. One of the most extended ideas is that aging is consequence of the accumulation of molecular damage. According to the oxidative damage theory, antioxidants should slow down aging, extending lifespan and healthspan. The present review analyzes studies evaluating the effect of dietary antioxidants on lifespan of different aging models and discusses the evidence on favor of their antioxidant activity as anti-aging mechanisms. Moreover, possible causes for differences between the reported results are evaluated.

Background: Several epidemiological studies and intervention trials have demonstrated that grapes and blueberries, which are rich in flavanols, can lower the risk of cardiovascular disease. However, the mechanisms of action of these compounds remain unclear due to their low bioavailability.
Objective: This study aimed to characterize the sensory properties, blood flow velocity, and oxidative stress of a polyphenol rich grape and blueberry extract (PEGB) containing approximately 16% flavanols (11% monomers and 4% dimers).

Purpose: Recurrent cystitis, particularly common in women, substantially diminishes patient quality of life and represents a major clinical practice and public health burden. Increasing development of resistance to antibiotics has encouraged the search for alternative treatments. The benefits of a food supplement associating two strains with proanthocyanidin A-rich cranberry and cinnamon extracts were evaluated in 80 women with a history of cystitis recurrence.

The Citri Reticulatae Pericarpium (CRP), is the aged peel of Citrus fruit, which contains phenols, flavonoids, and polysaccharides. This study aims to investigate dietary CRP supplementation on the growth performance, serum biochemical indices, meat quality, intestinal morphology, microbiota, and metabolite of yellow-feathered broilers. A total of 240 yellow-feathered broilers (1.

Background: Increasing evidence suggests that a diet rich in antioxidants may prevent erectile dysfunction (ED), but the impact of comprehensive dietary antioxidants on ED has been little studied.
Aim: To investigate the association between the composite dietary antioxidant index (CDAI) and ED risk in adult men.
Methods: The study performed a cross-sectional analysis using data from the 2001-2004 National Health and Nutrition Examination Survey to investigate the association between the composite dietary antioxidant index (CDAI) and ED.

Sulforaphane (SF) is a sulfur (S)-containing isothiocyanate found in cruciferous vegetables and is known for its potent anticancer properties. Broccoli sprouts, in particular, are considered safe and healthy dietary choices due to their high SF content and other beneficial biological activities, such as enhanced metabolite ingestion. The application of selenium (Se) is an excellent approach to enhance the abundance of SF.
