"Some of those enzymes are involved in cellular repair, so helping cells that have damage due to UV radiation, for example," says Martens. ... says Martens — these are both found in some foods ...
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible.
These oxidants can damage cells by starting chemical chain reactions such as lipid peroxidation, or by oxidizing DNA or proteins. [31] Damage to DNA can cause mutations and possibly cancer, if not reversed by DNA repair mechanisms, [36] [37] while damage to proteins causes enzyme inhibition, denaturation, and protein degradation.

In pathology and medicine, lipid peroxidation plays a role in cell damage which has broadly been implicated in the pathogenesis of various diseases and disease states, including ageing, [3] [4] whereas in food science lipid peroxidation is one of many pathways to rancidity. [5]
Higher levels of omega-6 fatty acids often found in ultraprocessed foods may interfere with the immune system’s fight against cancer cells, a new study says. Certain foods may disrupt your body ...
TP53: This gene encodes for the p53 protein, which is known to act on the apoptotic signalling pathway and is also described to be important in the break excision repair of cells that had their DNA damaged. p53 is a transcription factor that is involved in the transcription of many genes, some of which related to the process of cell response ...
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

Amino acids are necessary nutrients. Present in every cell, they are also precursors to nucleic acids, co-enzymes, hormones, immune response, repair and other molecules essential for life. Proteins are essential nutrients for the human body. [1] They are one of the building blocks of body tissue and can also serve as a fuel source.
