Oxidative Stress

Oxidative stress is defined as an imbalance between the production of reactive oxygen species, also known as free radicals or reactive oxygen and nitrogen species, and the antioxidants in the body.  Free radicals are uncharged molecules that are produced by the body as byproducts of different functions that occur, such as cellular reactions and metabolism of foods. Breathing digestion, exposure to radiation, the use of tobacco or alcohol, excessive exercise, high stress, and a poor diet are all common causes of the production of free radicals. Because free radicals are unstable, they are seeking other electrons from chemicals in the body that can help stabilize them. This causes them to react with almost anything that they come into contact with which leaves important cells in the body to have their electrons taken away. The free radicals begin to attack lipids, proteins, and DNA, which is why oxidative stress is deemed harmful. 

When antioxidant levels are lower than normal and accumulation of free radicals occur, this combination leads to damage. The damage that is done is done by oxidation, hence the term oxidative stress. When there are high levels of oxidative stress, multiple organs of the body are affected. Because of the repetitive oxidation that damages cells, this can lead to Alzheimer’s disease, diabetes, various cancers, heart disease, accelerated aging, and leaky gut syndrome.  

In order to prevent this, the consumption of antioxidants are crucial. They are able to donate an electron to the free radicals which allows the free radicals to become less reactive and stop attacking the important cells in the body. Glutathione is the number one antioxidant to consume. Good foods to consume to boost glutathione levels are milk thistle, whey protein, and foods containing sulfur, such as cruciferous vegetables. In addition to glutathione, vitamins A, C and E, beta-carotene, bioflavonoids, selenium, and zinc, are all helpful antioxidants to help minimize the reactivity of free radicals. Foods that are high in carotenoids, such as carrots, sweet potato, and squash, are beneficial for sight and anti-aging. In addition, spinach and other leafy greens are also good antioxidants sources for anti-aging. Berries and grapes have very high antioxidant levels as well. Green and white teas have high levels of the antioxidants polyphenols that can help fight cancer. Herbs and spices are another easy option in order to help increase antioxidant levels that have anti-inflammatory effects. Antioxidants should be consumed for a variety of reasons as well, not just to prevent oxidative stress. They can help repair essential enzymes, regulate the sleep cycle, and repair damaged blood vessels. 

Avoiding toxins and pollutant exposure is another good way to help minimize free radical damage. This can be done by eliminating chemical exposure from household and cosmetic products as well as the overuse of medications or antibiotics. Sleep, exercise, and a proper diet void of excess chemicals are crucial as well. It will help the body relax more and work more efficiently. By reducing stress, this will also reduce free radical production.
