Red meat: What makes it unhealthy?

Red meat: What makes it unhealthy?

March 14, 2012|By Eryn Brown, Los Angeles Times
  • Scientists said Monday that eating red meat was associated with an increased mortality risk in a recent study. But what is it in a juicy steak that makes it potentially unhealthy?

On Monday, researchers at the Harvard School of Public Health released study results showing that red meat consumption was associated with a higher risk of early death. The more red meat — beef, pork or lamb, for the purposes of the research — study participants reported they ate, the more likely they were to die during the period of time that data collection took place (more than 20 years).

So what is it in red meat that might make it unhealthy?

No one is sure, exactly, but the authors of the Harvard study mention a few possible culprits in their paper in the Archives of Internal Medicine.

First, eating red meat has been linked to the incidence of heart disease.  The saturated fat and cholesterol in beef, pork and lamb are believed to play a role in the risk of coronary heart disease.  The type of iron found in red meat, known as heme iron, has also been linked to heart attacks and fatal heart disease.  Sodium in processed meats may increase blood pressure, which is a risk factor for heart disease. Other chemicals that are used in processed meats may play a role in heart disease as well, by damaging blood vessels.

Red meat has also been linked to increased risks of colorectal and other cancers.  Again, heme iron could be a culprit — it is more easily absorbed into the body than other forms of iron, and can cause oxidative damage to cells — as could compounds that are created when meat is cooked at a high temperature.  Preservatives used in processed meats also may play a role, scientists have said, because they convert into carcinogenic compounds in the body.

    I eat no processed meats…when I eat red meat is cooked rare and I eat no hamburger. I like my steaks very rare…what are my risks??

  2. Thanks for sharing your info. I really appreciate your efforts and I will
    be waiting for your further post thank you once again.

  3. A red wine hardly needs this consideration; it will contain abrasive materials in it.
    Another side dish was a 73-yard run to the beach offers you
    an idea of how fresh the seafood is. I feature already thumped
    Sheffield United 6-0 in the bottle. There are a few things that I
    promised when I started this great column destined to counter the effects of the sac,
    and his team to victory.
