Garlic and cholesterol--Does everyone now need Lipitor?

Garlic May Not Lower Cholesterol
Study Shows No Improvement in Cholesterol Levels From Raw Garlic or Garlic Supplements

Lots of reports continue to hit the press about a small study that hoped to determine whether garlic as whole cloves (4 to 6), an aqueous extract of garlic called Kyolic, or an oil extract called Garlicin (high in allicin), or placebo. No differences in lipid numbers including LDL cholesterol were observed.

I believe that the researchers were sincere in their effort to follow an honest, scientfically sound clinical trial design. I'm personally not that surprised. The effect in prior studies has been modest, sometimes none. Does that mean that we should ignore the other studies that suggest there may be modest blood-thinning, anti-inflammatory, blood pressure-reducing, and cancer-preventing properties? No, it does not. Dr. Matt Budoff at UCLA even published a very small study in about 20 people that suggested a slowing of plaque growth by using Kyolic in persons tracked by CT heart scans.

Nonetheless, garlic is, at best, probably no more than a source of small benefits. The biggest fallout from this kind of report, however, is not the neutral results from garlic, but from the open door the drug companies sense when this happens.

If you read the WebMD report, you'll notice all sorts of advertisements from drug companies for statin cholesterol drugs ("Cholesterol health center"; "Understanding Cholesterol Numbers"; "There are two sources of cholesterol: food and family"), Niaspan (which I used to support but have been discouraged by the Kos companies excessively profiteering methods and recent big Wall Street sellout).

It doesn't follow. The failure of one nutritional strategy to reduce LDL does nothave to trigger a run to the drugs. Don't fall for it. Drugs have their place. So do supplements and food choices, which can be very powerful. Drug manufacturers and their marketing people salivate when something like this comes along, an open invitation to say, "If garlic doesn't work, _____ sure does."

Tim Russert Revisited

Tim Russert Revisited

A Heart Scan Blog reader brought this piece by Dr. MacDougall to my attention.

Dr. MacDougall created a fictitious posthumous conversation between himself and the late Tim Russert. MacDougall paints a picture of a hardworking, hard-living man who adhered to an overindulgent lifestyle of excessive eating. He concludes that a vegetarian, low-fat diet would have saved his life.

Beyond being disrespectful, I would differ with Dr. MacDougall’s assessment. In fact, I’ve heard an interview with Mr. Russert’s primary care physician in which the doctor claimed that Mr. Russert had been counseled on the need for a low-fat diet and, in fact, adhered to it quite seriously. Far from being an overindulgent, overeating gourmand, he followed the dictates of conventional dietary wisdom according to the American Heart Association. The low-fat diet articulated by Dr. MacDougall is simply a little more strict than that followed by Mr. Russert.

What exactly could Mr. Russert have done to prolong his life? Several basic strategies:

--Added fish oil. This simple strategy alone would have reduced the likelihood of dying suddenly by almost half.

--Eliminated wheat and cornstarch—Mr. Russert developed diabetes in the last few years of his life. By definition, diabetes is an inability to handle sugars and sugar-equivalents. Wheat and cornstarch yield immediate and substantial surges in blood sugar greater than table sugar; elimination causes weight to plummet, blood sugar to drop, and diabetes (at least in its early phases) can be eliminated in many people, particularly those beginning with substantial excess weight.

Just those two strategies alone would more than likely have avoided the tragic death that brought Mr. Russert’s wonderful life and career to an abrupt end.

Of course, he could have even taken his heart health program even further, as we do in the Track Your Plaque program. While the conversation has focused on how to avoid tragic events like sudden cardiac death, why not take it a step farther and ask, "How can coronary plaque be measured, tracked, and reversed?"

In that vein, Mr. Rusert could have restored vitamin D to normal levels; identified all hidden sources of heart disease using lipoprotein testing (though he had small LDL without a doubt, given his generous waist size, HDL of 36 mg/dl and high triglycerides); considered niacin. Simple, yet literally lifesaving efforts, that make reversal much more likely.

Those simple steps, in fact, would have tipped the scales heavily in Mr. Russert’s favor, making a heart attack and/or sudden death from heart disease exceptionally unlikely.

    Yes, I saw the McDougall post, too, and I also thought his fictitious  conversation was in very poor taste, not to mention very misleading and unhelpful in terms of what people could learn about avoiding a similar fate.

    It's not that we can't review and learn from what happened (and didn't happen) in Mr. Russert's case, but it's important to be factual and make sure it will actually teach something useful, not to mention not cross the line of good taste.

    Dr. Davis, I think there is a mile of difference in the way you refer to Mr Russert's untimely passing, with thoughtful commentary on what we can learn from this prominent example.  

    But Dr. McDougall's "posthumous interview" post, on the other hand, is nothing more than tacky self-promotion and yet more misleading vegetarian propaganda.

    I found a great book about Tim Russert at Walgreens.  It has stories from the people that knew him.  It sounds like he liked his beer.  I wonder if beer helped or hurt his condition.  Anyway, there is sample chapter of the book at:

    I found a great book that very few people probably know about.  The book is called "Tim Russert: We Heartily Knew Ye" and it contains stories from people that knew Tim. The book is only sold in Walgreens and they even have a sample chapter on the web at:
    Tim seemed to like beer a lot.  I wonder if it helped or hurt his condition?

    McDougall did something similar with Bill Clinton regarding his bypass surgery. Link:

    I was a McDougall follower for years.  Now I have virtually no respect for the guy.  I was probably the fatest vegan you've ever met.  Could not get below 190 pounds, was hungry all the time, skin was dry and cracked,  hair was like a Brillo pad, and blood sugar was rising.

    He has nothing to offer a diabetic or anyone with metabolic syndrome.   I think initially people see change on his diet, but long term I didn't seem to benefit.

    Russert also had the bulging eyes and thinning eyebrows of the untreated low-thyroid sufferer.

    But the McDougall post on Russert was beyond the pale.

    Same old!  Russert, I am sure, did NOT eat a low fat/high carb diet.  Low fat means for sure, less than 15% and more like 10% calories from fat and near 80% from carbs.  Most research and studies etc call 25% or even 35% low fat!  That is HIGH fat AND high carb which is definitely a deadly combo, just a more toxic version of SAD because undoubtedly, in trying (and failing) to go low fat, he was eating lots of manufactured, fake, food like substances that were loaded w/ transfats and chemical preservatives, dyes (note the inadvertent homonym pun), etc.  He died of misplaced, good intentions that were aborted by faulty education and industry PR, but definitely not a low fat diet!

    The bulging eyes are a sign in hyperthyroidism - over-active thyroid.
