Antioxidanter eller antioxidationsmedel är kemiska föreningar som motverkar oxidering. Oxidation är en kemisk reaktion som kan producera fria radikaler, som därigenom leder till kedjereaktioner som kan skada organismers celler. Antioxidanter som tioler eller askorbinsyra (C-vitamin) avslutar dessa

Certain "antioxidant" substances, such as vitamin C, are able to exploit the differences between cancer and healthy cells; they kill cancer cells while helping healthy cells. [9] Such substances have the ability to act either as antioxidants or as pro-oxidants, depending on their environment.

White blood cells work to block cell-damaging free radicals. Good sources of beta carotene are dark green leafy and yellow-orange fruits and vegetables. In the body, beta carotene is converted to vitamin A. Eating foods rich in beta carotene is recommended to possibly decrease the risk of developing stomach, lung, prostate, breast, and head and neck cancer. Keep eating fish, nuts, fruits, and vegetables. Two superstar heart disease protectors in these foods may also help fight cancer. Antioxidants and omega-3 fatty acids may be more powerful than we Cancer cells need extra fuel to support aggressive growth, produce more oxidants, Too many antioxidants may cause lung cancer spread (2019, June 27) Cancer is the second leading cause of death in the United States.

A: Antioxidants are substances that prevent damage to cells from highly reactive, unstable molecules called “free radicals.” A balance between antioxidants and free radicals in our body is important for health. If not kept in check, free radicals lead to cell damage linked to a variety of chronic diseases.

Antioxidants prevent a chemical process known as “oxidation,” which is a natural part of living and aging. Oxidation damages cells and can lead to the development of disease, including Alzheimer’s, heart disease, and cancer.

Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals.

2016-07-29 6 minutes ago In both mouse models and human cells, the antioxidants seemed to protect cancer cells by reducing the amount of DNA damage. That, in turn, reduced expression of a protein called p53. Though cancer therapeutics can successfully eradicate cancerous cells, the effectiveness of these medications is mostly restricted to several deleterious side effects.

Antioxidants are widely used to protect cells from damage induced by reactive oxygen species (ROS). The concept that antioxidants can help fight cancer is deeply rooted in the general population Antioxidant supplementation during radiation therapy poses a conundrum for the radiation oncologist, as antioxidants that protect normal cells from reactive oxygen species may provide the same benefits to cancer cells and reduce the efficacy of treatment.

In work on her thesis, Kristell Le Gal Beneroso went a step farther and examined how lung cancer and malignant melanoma in mice and human cancer cells respond to the addition of certain compounds of antioxidants.
