Hey Dr. Joe Feuerstein with the MD minute. Thanks for tuning in. Today I want to talk about a study that was just
published in the Journal of Nutrition looking at garlic extract and coronary
artery disease. Now I in my fellowship was trained to believe that garlic,
actually in long-term clinical studies, did not seem to reduce cholesterol. So I
tended to take people off garlic but this study probably has changed my mind. It was published, as I said, in a Journal of Nutrition and it looked at 55
people all of whom had metabolic syndrome. That’s increased blood sugars,
hypertension, weight issues, a high triglyceride, a low good cholesterol. This
is something very very common seen in the Western population and they all had
this. And then what they did is, they put them in a coronary calcium cat scan
to see how much plaque, you can measure how much heart disease, how much plaque you have, by looking at the amount of narrowing of the arteries on a cat scan.
And then they randomized them into two groups, one group were given 2.4 grams
with an aged garlic extract which they took for a year and that was 27 of them.
The other 28 were given a placebo for a year. What they did in this study, that
was really interesting, is they then looked at the coronary calcium score
again, a year later, and what they found was that if you’d taken the garlic for a
year, you had less plaque in your arteries, a specific type of plaque, than
the people taking placebo. So my take on this is that, this is very intriguing and
perhaps after all garlic in high doses, as aged garlic extract, may be an
important herb to be taking for people who are concerned about heart disease.
One should remember, however, that garlic has properties that can thin the blood
so that always needs to be considered. Dr. Joe Feuerstein. This is
the MD minute. Thanks for tuning in.
