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..
