Cholesterol, Red Yeast Extract and Health

It was about a month ago that I attended a seminar that was covering the health benefits of red yeast extract. During this seminar I heard some pretty convincing evidence supporting the beneficial effects that supplemental red yeast extract has had on cholesterol levels in various clinical trials.

As a scientist, I tried my best to pick apart the research, however that data was fairly convincing. I left the seminar open to the idea that red yeast extract may hold promise for its beneficial effects of lowering cholesterol.

This morning I read in an issue of Nutrition Outlook Magazine that stated that some red yeast extract products have been pulled from the market because they were adulterated with Lovastatin, a cholesterol lowering drug.

Now, this has me wondering, what kind of red yeast extract was used in the scientific trials? Did they also contain Lovastatin, and can that account for the cholesterol lowering effects that were observed?

While most likely we will never know the answers to this question, and I am sure that not all red yeast extract products have been adulterated, this kind of thing does make me even more hesitant about the efficacy (and safety) of herbal supplements.

This is another reason why I like the simplicity of using exercise combined with caloric restriction or short periods of fasting for weight loss purposes- you are getting the health benefits (including improvements in cholesterol profiles) simply by eating less, so you don't have to worry about what might, or might not be, in your functional food.

In this regard, you can think of eating less as "functional NO food".

Why should I eat more herbs and spices?

You may have noticed that part of my "mantra" for healthy nutrition includes eating lots of nuts, herbs and spices.

There is a very good reason why you should include as much variety of thse foods into your diet as possible...

Back when I worked in the supplement industry I was always amused when ever I looked through the list of potential new ingredients that had strong supporting research behind their effects.

The list typically looked something like this: Green tea extract, cinnamon extract, raspberry extract, pine nut extract, curcumin, cayenne pepper extract, mint, basil, rosemary...

Notice anything about this list?

These are all ingredients that you could be adding to your diet, especially if you are following the principle of nutrition by addition. Many of these ingredients are currently being studied for their potential to have positive effects on some very important markers of health, such as helping to manage healthy insulin levels, cholesterol levels and some of the more complex areas of body weight regulation.

The funny thing is, I often wonder if these ingredients would still be considered potential "functional foods" if we ate them more often. I believe that nuts, herbs and spices are one of the missing links in North American Health. If we ate them more often, then we would be regularly reaping their health benefits, and wouldn't need some fancy label like "functional foods" to describe them!

Take pinolenic acid for example. This compound is currently being studied for its potential beneficial effects on several ofthe 'hunger hormones' that regulate our feelings of hunger.
This ingredient has some big potential and, most likely will be available in a pill sometime in the very near future.

Of course, instead of buying the pill, you could always get it in its natural form by adding a handful of pine nuts to your salad.

A perfect example of Nutrition by Addition and the importance of eating a variety of nuts, herbs and spices.

PS - Here is what Craig Ballantyne had to say after he read Eat Stop Eat:

"This book will question everything you've ever been told about eating for fat loss. Bodybuilder mags have hyped up their eating & created inhuman workout programs for one reason - to sell supplements. That's right. Most nutrition programs are "designed" just to sell you stuff like protein powder and expensive post-workout sugar drinks. Brad's book turns the industry upside down and shows you how to eat normally, while making one slight, easy change that could bethe missing link in your fat loss nutrition program."

The Doctrine of Signatures

It is an unpleasant fact that science will always become outdated.

I am sure that a hundred years from now, schoolchildren will laugh at the principles we currently believe to be absolute scientific truths, just like how we now laugh at what was once "truth" centuries ago.

Take for instance the doctrine of signatures, which states that resemblance is a good indicator of effectiveness. If a particular plant resembles a human ear in its shape, then according to the doctrine of signatures this plant would have some sort of useful relevancy to the ear, perhaps being able to cure an earache.

While this now seems very arbitrary and somewhat unreliable, the doctrine of signatures still could be found in mainstream medical texts well into the 19th century and today is still the main principle of homeopathic medicine.

In fact, the doctrine of signatures can still be found in some nutrition myths that are still popular today. I know it's hard to believe that we would still use the doctrine of signatures with all of the research and scientific advancement that has happened in the world of nutrition, but take for instance fat, protein and cholesterol.

Many people still believe that eating fat will make you fat, that you need to eat large amounts of protein to build large amounts of muscle and that eating dietary cholesterol will make your blood cholesterol levels go through the roof.

Even though many of these "facts" are now largely disputed within the research community, people still believe them.

Why? You ask.

I think the reason is that these days science outdates itself so quickly that we no longer know what to believe. However, don’t blame the scientists for this.

You see, the job of science and scientists is to add to the existing body of research - To do their small part in answering the big question. However, most mainstream journalism and media need quick answers and they needed them yesterday! And this is where the major mistakes happen.

While scientists look at their work as something that helps answer a small piece of the puzzle, media looks at it as “THE ANSWER”.

This “jumping to scientific conclusions” can have dire consequences, as illustrated by one of my favorite articles, written by Gary Taubes and published in The New York Times back in 2002.

I think this is a very important piece of work that everyone should read, so please check it out by Clicking Here and let me know what you think of Gary's take on the last twenty years of nutrition research and policy.
