Oxidative stress is a natural process that occurs when the body comes in contact with ROS (reactive oxygen species) and free radicals. This process occurs daily and is part of normal aerobic metabolic functions in controlled amounts and plays a role in maintaining immunity and wound healing by killing pathogens.
When free radicals (unstable atom molecules) are produced in chronic and elevated levels, they become toxic to cells, damaging the mitochondria, which results in apoptosis (death of the cell). This development occurs when antioxidant molecules that aid in donating an electron to unstable free radical molecules cannot keep up. The consequences of imbalance and heightened production of free radicals result in oxidative stress that creates a sequence of genetic expressions resulting in pro-inflammatory states, which contributes to the development of chronic inflammatory illnesses such as cancer, diabetes, heart disease, leukemia, obesity, depression, chrons disease, colitis, lupus, Alzheimer's disease, atherosclerosis (hardening of arteries) and advanced aging.
Free radicals and ROS are caused by environmental toxins, food toxins, and stress in both the physiologic and psychologic systems.
You can reduce your exposure to oxidative stress by engaging in lifestyle changes such as eating a plant-based diet, avoiding fast food at all costs, avoiding artificial sweeteners, refined sugar, refined carbohydrates, and processed food. Environmental pollution is the main contributor, as is exposure to chemicals within your home. Other ways to reduce oxidative stress are by meditating, avoiding smoking, drinking alcohol, and avoiding certain drugs such as specific SSRIs, which stimulate oxidative stress responses, whereas others seem to lower them. Supplementing, exercising in moderation, and keeping psychological stress to a minimum are other ways to reduce exposure and prevent chronic illness.
