Is Oxygen A Carcinogen?

There are some people that believe in a fluoride conspiracy. They take out all the minerals (elements) in their drinking water because they have a fluoride-phobia.

Fluoride is naturally present in the food and drink we consume and is considered a normal constituent of the human body. The fluoride concentration in bones and teeth is about 10,000 times that in body fluids and soft tissues. Fluoride is ingested from several sources including foods, fluoridated and unfluoridated water, fluoridated toothpastes and some dietary supplements. (NIH 2017)

Recommended fluoride intake.

Moderation is the key. Not enough fluoride and you’ll have weak teeth and bones. Too much fluoride can kill you. Did you know that too much oxygen can kill you, too?

Oxygen: our major carcinogen?
Evidence has accumulated implicating that atmospheric oxygen can be considered as an important environmental mutagen, whose action can be potentiated by a variety of environmental factors. Under normal conditions oxygen genotoxicity is largely prevented by a cellular antioxygenic defense system, which must be extremely efficient, but might not be entirely safe. A better understanding of this defense system may help to suggest how the incidence of carcinogenesis can be minimized.

Can inhaled oxygen cause cancer?
Date: January 13, 2015
Source: PeerJ
Summary:
The ancient physician/alchemist, Paracelsus, said: ‘The dose makes the poison.’ According to a new study, even oxygen may fall prey to the above adage. While essential to human life, aspects of oxygen metabolism may promote cancer. Capitalizing on the inverse relationship of oxygen concentration with elevation, researchers found lower rates of lung cancer at higher elevations, a trend that did not extend to non-respiratory cancers, suggesting that carcinogen exposure occurs via inhalation.

Oxygen toxicity
From Wikipedia, the free encyclopedia Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O2) at increased partial pressures. It is also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning. Historically, the central nervous system condition was called the Paul Bert effect, and the pulmonary condition the Lorrain Smith effect, after the researchers who pioneered its discovery and description in the late 19th century. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs and eyes. Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy.

You can also consume too much water — drowning. Listen to your body for the happy medium.

    So, you know…
    When we witness the Lord sow snow
    See a glimpse of beauty
    Ohhhh…
    Snow
    Turn the dark to bright
    Absorb the sound
    Reflect the light
    Peace is found
    Clinging tight
    So, Lord, sow snow!
    Ohhh….
