In support of this concept, we have shown that mtDNA mutations accumulate in proportion to life span in several animals, that increasing mitochondrial anti-oxidant defense systems extends lifespan, that ancient human mtDNA variants that modify energy production and
oxygen radical production can modulate longevity and risk for neurodegenerative diseases, and that patients with the neurodegenerative disease, Alzheimer Disease, have increased mtDNA mutations.

At the hearing, Carpenter suggested that cell phones may increase the brain's
production of reactive forms of
oxygen called free
radicals, which can interact with and damage DNA.
One possibility, advanced by the Wisconsin team, is that restricting food consumption reduces the
production of tissue - damaging
oxygen free
radicals that are a byproduct of food metabolism.
The Einstein team suspected that cysteine was helping to kill TB bacteria by acting as a «reducing agent» that triggers the
production of reactive
oxygen species (sometimes called free
radicals), which can damage DNA.
They describe that the alterations are due to a disproportionate, though transitory, increase in the
production of
radical oxygen species (ROS) in the hypothalamus.
In one recent study Achyranthes bidentata polypeptides (ABPP) separated from the aqueous extract of Achyranthes bidentata were shown to reverse
production of intracellular
radical oxygen species (ROS) and confer neuroprotective effects on NMDA receptors.
All of these happen because the free
radicals and reactive
oxygen species produced caused significant damage to the thyroid and reduced thyroid hormone
production.
The
oxygen you breathe can also contribute to the
production of free
radicals.
Energy metabolism and the
production of Reactive
Oxygen Species (very small molecules that can result in significant damage to cell structures, of which include oxygen ions, free radicals and peroxides) are thought to underpin many nuerodegenerative disorders, and creatine is thought to enhance the brains ability to survive the metabolic and physical trauma associated with these condi

Superoxide dismutase (SOD) is found inside the body's mitochondria (the
oxygen - based energy factories inside most of our cells) where it provides protection against damage from the free
radicals produced during energy
production.
In the process of energy
production, single electrons escape from the «factory line» and react with
oxygen molecules to form free
radicals such as peroxide and superoxide.
Oxidative stress describes the state of the body in which the
production of reactive
oxygen species (ROS), including free
radicals, overwhelms the body's antioxidant defences.Our body tries to maintain a constant balance between free
radicals and antioxidants.
Generation of reactive
oxygen species, or free
radicals such as superoxide and hydrogen peroxide, is a normal byproduct of metabolism, but can damage cellular machinery when excessive and impair the
production of cellular energy, which becomes a vicious cycle as energy - intensive repair processes become untenable (25, 26).
If balls out training increases the
production of damaging
oxygen radicals than it makes perfect sense to limit oxidation as much as possible, right?
Similarly, a problem with antioxidant
production can result in the buildup of reactive
oxygen and nitrogen species, otherwise termed «free
radicals», in the mitochondria.
Much like rust, this is a continuous wear and tear biochemical reaction in our cells producing free
radicals (a by - product of
oxygen - based energy -
production processes).
So, the thinking is that lower methionine intake leads to less free
radical production — the so - called «reactive
oxygen species,» which slows the rate of DNA damage, which then would slow the rate of DNA mutation, slowing the rate of aging and disease — thereby potentially increasing our lifespan.
The therapeutic dotential of dietary precursor modulation by a fish - oil - supplemented diet (n - 3 fatty acids), such as eicosapentaenoic acid (C20: 5,n - 3) and docosahexaenoic acid (C22: 6,n - 3) in the therapy of ulcerative colitis has been shown to result in a 35 % to 50 % decrease in neutrophil
production of LTB4.28 Significant improvement in symptoms and histologic appearance of the rectal mucosa has been observed in several small series of patients with Crohn's disease and ulcerative colitis given fish oil at 3 to 4 g daily for 2 to 6 months in uncontrolled studies.29 However, a larger, randomized, double - blind trial comprising 96 patients with ulcerative colitis failed to reveal any benefit in remission maintenance or treatment of relapse on 4.5 g of eicosapentaenoic acid daily, despite a significant reduction in LTB4 synthesis by blood peripheral polymorphonuclear cells.30 It should be emphasized, however, that the anti-inflammatory actions of the fish oils, in addition to inhibition of LTB4, include suppression of IL - 1 and platelet activating factor synthesis and scavenging of free
oxygen radicals.30 The impact of increased lipid peroxidation after fish oil supplementation should be considered when altering the n - 6: n - 3 fatty acid ratio.31 Antioxidant supplementation may be able to counteract the potentially adverse effects of n - 3 fatty acids.
