What is oxidative stress?
Oxidative stress often occurs as a side effect of normal human functioning. When cells in the human body use oxygen to produce energy, they can create reactive molecules known as free radicals. The free radical molecules are unstable because they lack the electron. Inside the body, they can potentially react with almost any other molecule. Oxidative stress is a cell damage associated with chemical reaction between free radicals and other molecules in the body.
Cell damage caused by oxidative stress is considered a number of diseases such as cancer or autoimmune disease. The body generally uses nutrients known as antioxidants to control cellular stress. It is believed that antioxidants increase the immunity and prevention of cancer, heart disease, diabetes and macular degeneration. Antioxidants can even help slow down the symptoms of aging and progression of Alzheimer's disease.E body. When the levels of free radicals and antioxidants are unbalanced, free radicals are left to makechemically combined with body cells. Free radicals are so unstable that they can react with almost any other type of molecule. They are assumed that they are capable of significant damage to cells and proteins in the body. Free radicals can be responsible for damage to DNA cells so that the cell mutates and reproduce control and creates cancer.
Some amounts of oxidative stress are almost always an inevitable outcome of aging. Other factors that can contribute to oxidation cell stress include cigarette smoking, pollution, exposure to excessive sunlight and poor nutrition. Doctors believe that cellular stress can largely be checked by avoiding cigarettes, using UV protection and consuming a high antioxidant diet.
Antioxidants are nutrients that generally act to clean the body of free radio by giving up electron. When the free radical molecule takes the electricRon of antioxidant molecules, free radical is stabilized. After stabilization, free radical can no longer cause damage.
Common antioxidants include vitamins A, C and E. Zink, selenium and plant polyphenols are well known antioxidants. Antioxidants are most common in fruits, vegetables, herbs and tea. Doctors generally agree that consumption of diet rich in antioxidants can help slow the normal development of oxidative stress.
