Free radicals in disease and health

Slobodni radikali su atomi ili skupine atoma s nesparenim brojem elektrona koji mogu započeti lančane reakcije u tijelu. Predstavljaju opasnost organizmu jer mogu reagirati s vrlo važnim staničnim komponentama kao što su DNA i membrane, no s druge strane, u manjim koncentracijama obavljaju vrlo važne uloge signaliziranja pri vitalnim procesima. Doprinose nastanku mnogih kroničnih zdravstvenih problema kao što su kardiovaskularne bolesti, upalne bolesti i rak ako dođe do velikog poremećaja radikala i antioksidanata u tijelu. Redoks homeostaza je jako važan pojam koji se odnosi na ravnotežu proizvodnje i uklanjanja viška slobodnih radikala. Pri urušavanju iste, dolazi do oksidativnog stresa kjučnog čimbenika u nastanku nekih kroničnih i degenerativnih bolesti. Unos antioksidanata koji sprječavaju štetne učinke slobodnih radikala smanjuje pojavnost kroničnih i degenerativnih bolesti. Tijelo je potrebno dugoročno štititi od oksidativnog stresa unosom funkcionalne hrane u organizam i izbjegavati oksidativne izvore kao što su cigarete, alkohol, droge, stres... Naše zdravlje doista ovisi o izboru našeg životnog stila.Free radicals are atoms or groups of atoms with an unpaired number of electrons that can start a chain reaction in the body. They represent a danger for the body, because they react with very important cellular components such as DNA and membranes, on the other hand, at lower concentrations they perform a very important role in signaling of vital processes. Contributing to the onset of many chronic health problems such as cardiovascular disease, inflammatory disease and cancer when there is a large imbalance between radicals and antioxidants in the body. Redox homeostasis is a very important term that refers to the balance of production and removal of excess free radicals. Collapse of that balance leads to oxidative stress with implications in the development od several chronic and degenerative diseases suggests that it is very important to ingest antioxidants that prevent the harmfull effects of free radicals. It's necessary to protect the body in the long term from oxidative stress by intake od functional foods and avoid oxidative sources such as cigarettes, alcohol, drugs, stress... Our health really depends on the choice of our lifestyle
