Vilken typ av antioxidant är N-Acetylcystein? Är den syntetisk labb-produkt eller är det naturligt. Sanningen är att den egentligen är ett
Various dietary antioxidants have shown considerable promise as effective agents for cancer prevention by reducing oxidative stress which has been implicated in the development of many diseases, including cancer. Antioxidant nutrients and carotenoids have been inconsistently associated with ovarian cancer risk. We examined the relationship between intake of dietary and supplemental antioxidant nutrients including vitamins C, E, and selenium as well as carotenoids and vitamin A and ovarian cancer in 133,614 postmenopausal women enrolled in the Women's The notion of cancer prevention through antioxidant intervention arises from the fact that fruits and vegetables contain antioxidants and are linked to low cancer rates in those who consume them. Protection against DNA damage by plant food products can be demonstrated in vitro. Dietary antioxidants and the aetiology of pancreatic cancer: a cohort study using data from food diaries and biomarkers.

Studies on Polyphenolic Antioxidants and Neuronal Regeneration.
Certain dietary antioxidants such as vitamin E and vitamin C are important for maintaining optimum health. There is now much interest in polyphenolic products of the plant phenylpropanoid pathway as they have considerable antioxidant activity in vitro and are ubiquitous in our diet. Rich sources include tea, wine, fruits and vegetables although levels are affected by species, light, degree of
Banim PJ(1), Luben R, McTaggart A, Welch A, Wareham N, Khaw KT, Hart AR. Author information: (1)Department of Medicine, University of East Anglia, Norwich, UK. The use of antioxidants during cancer therapy is currently a topic of heated debate because of an overall lack of clear research findings. Some data suggest antioxidants can ameliorate toxic side effects of therapy without affecting treatment efficacy, whereas other data suggest antioxidants interfere with radiotherapy or chemotherapy.
antioxidants decrease reactive oxygen species (ROS) levels, which paradoxically increase the proliferation rate of lung cancer cells, resulting in greater tumor
