Sources of Oxidative Stress

The body constantly takes in oxygen and also reacts to it. Oxygen is a necessary component for cells to produce energy. Free radicals are produced during this process and they in turn react to other molecules within the cells. When this happens, oxidative damage can occur within proteins, genes and membranes in the body. Oxidative stress has been linked to Alzheimer's, chronic fatigue syndrome, bipolar disorder and the aging process. Antioxidants within the body counteract free radicals. An individual's own genetic makeup, their diet and exposure to such things as air pollution determine how well their body can counteract free radicals.

Environment

• Air pollution is a leading cause of environmental oxidative stress. Those who live in big cities find air pollution hard to avoid. High amounts of sun exposure can also cause oxidative stress. Wearing a sunscreen at all times is extremely important. According to ScienceDirect.com, reactive oxygen species (environmentally-induced carcinogenesis) are one of the most abundant sources of free radicals in nature.

Smoking and Alcohol Consumption

• Lifestyles that include smoking are at a higher risk for oxidative stress. When inhaling cigarette smoke, the cells in the lungs are exposed to cigarette extract, which in turn contributes to oxidative stress. Even moderate amounts of alcohol consumption can increase the risk for oxidative stress. Alcohol supports the generation of reactive oxygen species and interrupts the body's ability to react against them, even lowering antioxidant levels in the body.

Diet

• Diets lacking in high antioxidant level will not assist the body in fighting off free radicals. Antioxidants aid the body tremendously in warding off reactive oxygen species. Diets containing high amounts of animal protein, sugar, hydrogenated fats and not enough water are at higher risk for oxidative stress. Avoid foods that are full of preservatives whenever possible. Opt for wholesome foods such as whole grains, fruits and vegetables, beans and legumes, as well as foods high in omega-3s such as salmon and tuna. Drinking plenty of clean water will also aid the body in fighting off free radicals as well as keeping it clean and free of toxins.
