Eating Trans Fats Linked to Depression

But Study Shows a Diet That Includes Olive Oil Can Cut Risk of Depression By Kathleen Doheny

Jan. 26, 2011 -- Eating too much trans fat, long known to raise heart disease risk, can also boost your risk of depression, new research suggests.

Eating a heart-healthy diet with olive oil can lower the risk of depression, says researcher Almudena Sanchez-Villegas, PhD, associate professor of preventive medicine at the University of Las Palmas de Gran Canaria in Las Palmas, Spain. The study included more than 12,000 people.

"The participants with an olive oil consumption higher than 20 grams a day (about 0.7 ounces) had a 30% lower risk of depression than those without consumption or with a very low consumption of olive oil," Sanchez-Villegas tells WebMD.

Those who took in the most trans fats, however, had up to a 48% increased risk of depression.

The unhealthy fats, says Sanchez-Villegas, are believed to lead to biological changes in the body linked with both heart disease and depression.

The study is published online in PLoS ONE.

Diet and Depression

The researchers evaluated 12,059 men and women, with an average age of 37. All were free of depression at the start of the study.

The men and women completed a food frequency questionnaire, describing their intakes of various types of fat. After a median follow-up of 6.1 years (half were followed longer, half less) 657 new cases of depression had been diagnosed.

The researchers then looked at the type and amount of fat intake to see if it played a role. It did.

Those who ate a high amount of trans fat -- the fat type found in fast food, industrially produced pastries, and certain whole milk products -- had an increased depression risk, while those who ate the most olive oil had a lower risk than those with a low consumption of olive oil or no olive oil.

The trans-fat intake in the participants was fairly low, Sanchez-Villegas says. Those in the highest intake group took in about 1.5 grams daily, and it was in that group the researchers found the 48% increased risk of depression.

In the study, both good fats and bad showed what scientists call a ''dose-response'' relationship. "More consumption, more protection

My Battles With Daily Temptation

Everyday is a good day to be alive.  Not that the world becomes perfect overnight --- it’s just that the amount of possibilities is staggering.  So does the daily temptation.

Being a little older than some of my colleagues, it’s easier to see why things seem easier for me.  I know better, and that “last” bottle of beer?  I know it’s going to haunt me --- if not in the morning, but for months or years to come.

It’s easy to think back to easier times, when, after a day of solid work, I’d go thinking how a couple of bottles of beers, cigarette breaks or a heavy meal might do me some good --- but now, these things are part of the daily temptation I try so hard to avoid.

 

Alcohol – I never believe in alcohol abuse.  The alcohol doesn’t abuse the body of the drinker, but when the drinker decides to abuse the alcohol, that’s when things go horribly wrong.  Part of the daily temptation is knocking back a few after a hard day’s work.  I used to think that I deserve that shot, or that bottle --- but now I consider that I deserve MORE.  I deserve my health, for what lifestyle changes I put my body through.

Smoking – I tried it when I was younger.  My advice is, if you don’t smoke already, don’t even try it.  It’s a nasty habit that leaves your teeth stained and your hands constantly smelling like burnt excess.  Daily temptation is storming out of a conference call and lighting one of these up in the designated smoking area.  Most buildings have designated smoking areas that just make you feel bad about smoking, like an empty rooftop.  If that wasn’t a sign enough already, consider your health.  I considered mine.

Heavy meals – A good meal is something to be valued, treasured, even --- for a meal only happens once in your life.  But constantly binge eating only reinforces the bad habit as instant gratification.  It makes your body ill and makes you think less of yourself.  I can’t think of a time when something deep-fried or buttered isn’t a daily temptation, and I’m not bound to try and decode why --- I don’t want to confess these sins from a hospital bed, see.  :D
