Quotes About Free radicals

Vitamin C also protects other tissues from free-radical damage. Whenever it encounters a free radical, it sacrifices one of its own electrons in order to 'pacify' and neutralize the intruder, destroying itself in the process. This running battle between vitamin C and free radicals occurs hundreds of thousands of times per second, and if you fail to supply your body with adequate quantities of this friendly free-radical scavenger, the enemy will eventually erode your body by attrition.

The body concentrates vitamin C around brain and nerve cells specifically to protect them from oxidation and free-radical damage, because vitamin C is one of nature's most powerful antioxidants.

the fact that magnesium deficiency increases the production of free radicals and decreases

In the normal process of producing energy, each mitochondrion produces hundreds if not thousands of free radical molecules each day. Multiply that by the ten million billion mitochondria that we each possess and you come up with an unfathomable number, ten

how effective would, say, a vitamin E capsule or a tablet of vitamin C be when confronted by this onslaught of free radicals? Common

one molecule of vitamin C is oxidized by one free radical. (This one-to-one chemistry is called a stoichiometric reaction by chemists.) Can you imagine how much vitamin C or other oral antioxidant it would take to neutralize the untold number of free radicals generated by the body on a daily basis?

to the brain? One of the most common ways is through physical modification by glucose. Sugar molecules attach themselves to LDL and change the molecule's shape, rendering it less useful while increasing free radical production.

people with celiac have significantly increased production of free radicals, and they exhibit free radical damage to their fat, protein, and even DNA.16 In addition, they also lose their ability to produce antioxidant substances in the body as a result of the immune system's response to gluten. In particular, they have reduced levels of glutathione, an

But a caveat: Once free radicals damage the LDL molecule, it's rendered much less capable of delivering cholesterol to the brain. In addition to oxidation destroying the LDL's function, sugar can also render it dysfunctional by binding to it and accelerating oxidation. And when that happens, LDL is no longer able to enter the astrocyte, a cell charged with nourishing neurons. In

The bottom line is that if you want to reduce oxidative stress and the action of free radicals harming your brain, you have to reduce the glycation of proteins. Which is to say, you have to diminish the availability of sugar. Pure and simple.

Now, here's the key thing you need to know about mitochondria: Like any other sort of engine, they generate energy, but they also generate waste. However, unlike your car engine, which turns gasoline into energy while creating smog, the mitochondria turn food into energy while creating something called free radicals.

She bathed daily, a practice that fills the body with electrons, countering the free radicals that are a major source of oxidative stress and cell degeneration.

The human brain is at particularly high risk for damage by free radicals because of its high degree of metabolism compared to other tissues, while lacking the levels of antioxidant protection found elsewhere in the body.

Antioxidants are chemicals that break down or neutralize the damaging effects of free radicals - chemicals produced as a byproduct of normal cellular metabolism.

The citation for the 1971 Nobel Prize in Chemistry reads, 'for contribution to the knowledge of electronic structures and geometry of molecules, especially free radicals,' and therefore implies that the Prize has been awarded for a long series of studies extending practically over my whole scientific life.

Antioxidants are molecules that neutralize free radicals, so the thinking is that if you take a lot of them in the form of supplements, you can counter the effects of aging. Unfortunately, there is no scientific evidence to support that.

Denham Harman had not, in 1945, read an article about aging in his wife's Ladies' Home Journal and developed a theory that free radicals and antioxidants are at the heart of human aging. Harman's idea was never anything more than a hunch, and subsequent research proved it to be wrong, but nonetheless the idea has taken hold and will not go away. The sale of antioxidant supplements alone is now worth well over $2 billion a year.

iron inhibits the absorption of important growth factors such as zinc. Furthermore, iron is an oxidative substance that can exacerbate the production of free radicals and might even increase the risk of pre-eclampsia.9

When a molecule of vitamin C encounters a free radical, it becomes oxidised and thereby renders the free radical innocuous. The oxidised vitamin C then gets restored to its non-oxidised state by an enzyme called vitamin C reductase. It is like a boxer who goes into the ring, takes a hit to his jaw, goes to his corner to recover, and then does it all over again.

If free-radical leak is fast, degenerative diseases set in quickly; if it's slow, they're postponed or even abrogated altogether.

of oxygen, whether we think of it as 'good' or 'bad', is the formation of free radicals. As conventionally stated, the idea that breathing oxygen causes ageing is disarmingly simple. We produce free

Storing genes, vulnerable informational systems, in the immediate vicinity of the mitochondrial respiratory chains, which leak destructive free radicals, is equivalent to storing a valuable library in the wooden shack of a registered pyromaniac.

Grow some wild geranium," he suggested. "Or buy the extract online." Geranium niveum is the Tarahumara wonder drug; according to the Journal of Agricultural and Food Chemistry, it's as effective as red wine at neutralizing disease-causing free radicals. As one writer put it, wild geranium is "anti-everything—anti-inflammatory, antiviral, antibacterial, antioxidant.

Vanilla is anti-inflammatory and reduces free radicals.
