More Fuel To The Fire: Red Meat Leads to Cancer and Heart Disease

Its been speculated for some time..that eating red meat leads to an increased incidence of heart disease and cancer. And an analysis, published  in Archives of Internal Medicine, using data from two studies that involved 121,342 men and women, further confirms the fact that consuming red meat is associated with a sharply increased risk of death from cancer and heart disease; and the more of it you eat, the greater the risk.

People who ate more red meat were less physically active and more likely to smoke and had a higher body mass index, researchers found. Still, after controlling for those and other variables, they found that each daily increase of three ounces of red meat was associated with a 12 percent greater risk of dying over all, including a 16 percent greater risk of cardiovascular death and a 10 percent greater risk of cancer death.

The increased risks linked to processed meat, like bacon, were even greater: 20 percent over all, 21 percent for cardiovascular disease and 16 percent for cancer.

You might say that you had suspected this all along,  but the new results suggest a surprisingly strong link and further reinforce this conclusion.

The cooking method is said to play a role in causing cancers

The modus operandi for red meats and heart disease is quite clear-cut: the high saturated fats content leads to cholesterol deposition in the walls of the arteries. In the case of cancer, the mode of action is less clear-cut. Some postulated causes include:

  • the presence of conjugated linoleic acid (CLA) in grass-fed meat which has anti-cancer properties.
  • the mode of cooking, with preference to ‘low and slow’ and doneness.
  • chemicals (nitro compounds) used in preservation of processed meats.
  • breakdown of blood components like haem to harmful cancer-causing chemicals (read more here).

This probably why meat-eating countries like Argentina do not report high incidences of gut cancer..

 

 

Court Ruling: Mobile Phones Cause Brain Tumor

For the very first time, a supreme court has ruled that using mobile or cordless phones is directly linked to causing brain tumors, affirming what many scientists have been saying for years now about the dangers of cell phone radiation. The U.K.’s Telegraph reports that 60-year-old Innocente Marcolini, who developed a tumor in his trigeminal nerve, was ruled to have suffered this fate as a result of using his mobile handset for up to six hours every day for 12 years.

Italy’s Supreme Court in Rome, ruled that there is a “causal link” between Marcolini’s mobile phone use and the non-cancerous tumor that caused the entire left side of his face to become paralyzed. Experts provided evidence at a recent trial showing that the electromagnetic radiation emitted from mobile and cordless phones damages cells.

Though Marcolini’s brain tumor is non-cancerous, it still reportedly threatened to kill him because it had been encroaching on his carotid artery, which is the major blood vessel responsible for transporting blood to the brain. The tumor also developed directly next to where Marcolini typically held his phone next to his ear, illustrating how significantly mobile phone radiation can disrupt proper brain cell function.

WHO classified mobile phones as Class B carcinogens last year.

In the face of repeated studies that there was no direct causative effect, this landmark ruling takes a new perspective on the possible dangers of prolonged mobile phone usage.  To add fuel to the debate, last year the WHO ( World Health Organisation) urged limits on mobile use, calling them a Class B carcinogen.

International radiation biology expert Michael Repacholi said: “Studies show no evidence of cancer”. But he quickly adds : “If you are worried, use a headset, hands-free or loudspeaker.”
