This is why ozone holes first formed, and are deeper, over Antarctica. Early models failed to take PSCs into account and predicted a gradual global depletion, which is why the sudden Antarctic ozone hole was such a surprise to many scientists. [28] [29] [30] It is more accurate to speak of ozone depletion in middle latitudes rather than holes.
The American Cancer Society warned in 2010 that evidence for the efficacy of ozone therapy against cancer is inconclusive, and the therapy may be dangerous. [4] For treatment of HIV/AIDS, although ozone deactivates the viral particles in vitro, well-designed studies have shown there is no benefit for living patients. [17]
For breast cancer, there is a replicated trend for women with a more "prudent or healthy" diet, i.e. higher in fruits and vegetables, to have a lower risk of cancer. [ 18 ] Unhealthy dietary patterns are associated with a higher body mass index suggesting a potential mediating effect of obesity on cancer risk.
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
The ozone hole was much more seen as a "hot issue" and imminent risk compared to global climate change, [13] as lay people feared a depletion of the ozone layer (ozone shield) risked increasing severe consequences such as skin cancer, cataracts, [23] damage to plants, and reduction of plankton populations in the ocean's photic zone. This was ...
In addition, a low-residue diet is often prescribed before and/or after abdominal surgery or cancer treatments. A low-fiber diet is a low-residue diet eliminating dietary fiber in particular. The terms are not always distinguished, but when they are, a low-residue diet will include additional restrictions on foods such as dairy products, which ...
Both types of ozone depletion were observed to increase as emissions of halocarbons increased. Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents harmful wavelengths of ultraviolet (UVB) light from passing through the Earth's atmosphere.
The Mayo Clinic Diet is a diet book first published in 1949 by the Mayo Clinic's committee on dietetics as the Mayo Clinic Diet Manual. [1] Prior to this, use of the term "diet" was generally connected to fad diets with no association to the clinic.
