Probiotics and berry-associated polyphenols: catabolism and antioxidative effects

Popular Abstract in Swedish Yttre faktorerna i omgivningen som UV-strålning från solen, rökning, läkemedel, maten och påfrestande livssituationer kan leda till att kroppens celler börjar överproducera molekyler som kallas syrefria radikaler. Dessa molekyler reagerar kemist mycket lätt med omgivande ämnen. När syrefria radikaler bildas i kroppen i normala mängder ingår de som en del av immunförsvarOxidative stress can cause damage to DNA, proteins and lipids and is associated with inflammation and various human diseases as cancer, atherosclerosis, and autoimmune diseases. Polyphenol-rich diet, such as fruits and berries, may act as antioxidants and prevent oxidative stress and, thereby, associated diseases. Administration of lactic acid bacteria (LAB) can affect the microflora in the gastro
