More on erectile dysfunction

Several facts on erectile dysfunction and coronary plaque:

If you have erectile dysfunction, there's at least a 50% chance you also have coronary plaque.

If you have coronary plaque by a CT heart scan, there's a 50% chance you have erectile dysfunction.

If you have symptomatic coronary disease (chest pains, breathlessness, prior heart attack), there's a 90% chance you also have erectile dysfunction.

Coronary disease is characterized by a dysfunctional state of the "endothelium", or inner lining of the coronary arteries. Erectile dysfunction is characterized by dysfunction of the endothelium of the penile circulation. Same phenomenon, different territories. (There are other differences, of course, but the two conditions share this fundamental phenomenon.)

If you have any doubts about the physiologic effects of the supplement, l-arginine, just give it a try if you have erectile dysfunction. The erection enhancing effects alone should convince you that a genuine artery-dilating effect is exerted by this very powerful nutritional supplement.

If l-arginine fails by itself to restore full erectile capacity, there are additional strategies, both nutritional and medical, that you can consider.

    Implication in contributing to risk of death from heart disease

    A recent Johns Hopkins study testing the addition of L-arginine to standard postinfarction treatment has implicated L-arginine supplementation with an increased risk of death in patients recovering from heart attack.[5] This study has been discussed in some detail in : "Reverse Heart Disease Now" by Stephen T Sinatra MD and James C Roberts MD, publ. Wiley 2006 ISBN 0-471-74704-1 at pp 111 -113.

    I actually posted a full discussion of this issue a few months back on the Track Your Plaque website ( I still believe what I said then:

    "Should we panic and stop l-arginine based on this report?

    Take a closer look.  We don’t think so. First of all, two of the deaths occurred months after l-arginine treatment was stopped. Two other deaths were due to infections and therefore likely unrelated to heart disease or l-arginine use. This leaves two deaths attributable to heart disease in the l-arginine group.

    "Numbers this small are likely to represent chance statistical effects, especially in view of the small size of the overall trial. In other words, in all likelihood, a larger study would have revealed more reliable numbers not as susceptible to chance effects.

    "What about all the other studies that have looked at l-arginine? We should view this one study in the context of all preceding experiences. No excess dangers have been observed in thousands of participants with coronary disease, angina, peripheral vascular disease, and heart failure over the last decade of investigation.4 Many of the participants with heart failure in these studies were sufferers of prior heart attack, just like the VINTAGE MI participants.

    "Let’s also not forget that l-arginine is a food substance. Do fish, chicken, eggs, and nuts also pose danger? Of course not.

    "As always, each study should be viewed within the broader context of the available scientific and clinical experience. The overwhelming experience, as well as common sense, suggests that the VINTAGE MI Trial is a statistical fluke."

    In other words, I find this so counter to all prior experiences that I think it's a fluke. But, of course, the pharmaceutical industry-friendly media make hay of such reports.

    Due to the rising competition in the ED drugs market arena, all the ED drugs are trying to target their customer base by harping on the advantages that they are having over their competitors. Hence you will find ED drugs that either talk about their lasting effects, their minimum side effects or the other benefits that they mete out apart from the cure of ED. Though these claims are not always false one should not completely sway away in these claims. A very good ED drug might also fail to suit a particular patient. ED drugs and in fact any drug should be had only on doctor’s advice.

    sexual dysfunction such as ED or impotence can be treatable,some of them in the form of medicines, some in the form of specialized techniques, and some in the form of herbal supplements.

    I am only 40. Started having problems about a year ago. Tried "herbal" remedies, was hit or miss, mostly miss. Also libido was on the down turn, I just didn't feel like I needed or wanted sex... Got a trial pack from with 6 pills. The first three I took worked perfectly. Took on empty stomach or at least one hour after a meal. Within an hour, took effect. Makes my face flush and nose run (common side effects) The fourth time I took it, I split the pill in half to see if it would work at lower dose (I was taking a 50mg dose) It works. Also, most of the time, it still has effects several hours after. Even up to the next morning if taken at night.

American Heart Association stamp of approval

American Heart Association stamp of approval

The American Heart Association (AHA) has a program called the Heart-Check Mark, an "approval" process that permits a food manufacturer to affix the AHA logo and stamp of approval on various food products.

A company simply makes application to the AHA. The application and product details are reviewed and then approved or turned down.

To date, 106 companies have obtained the AHA stamp of approval on 768 products. What kinds of products are on the approved list? Here's a sample:

--Honey Bunches of Oats

--Kellogg's Frosted Mini-Wheats

--Cocoa Puffs cereal

--Cookie Crisp cereal ("The great taste of chocolate chips in every bite!")

There are 764 others. If you doubt this, just go to the store and take a look at the product containers.

What the heck is going on here? Most of us with any judgment know that these products are pure sugar. They may contain "no more" than 15-40 grams sugar per sugar, but the principal products--corn, wheat, fructose--mean that these products are, in effect, nearly pure sugar. Yet they carry the AHA stamp of approval.

What do products like this cause? It's a long list but the major effects include:



--Drop in HDL

--Rise in triglycerides

--Small LDL particles

--Heightened inflammation (i.e., C-reactive protein)

--Mental cloudiness

Need I go on? Why are products like these and many others deserving of the AHA heart-check approval? Because they lack high fat and saturated fat (3.0 grams, 1.0 grams respectively, by AHA criteria). In other words, just lacking these ingredients means that, to the AHA, they qualify as "heart healthy."

By that same line of reasoning, many candy bars are "heart healthy", as are many cookies and cupcakes.

What's the reason behind this extraordinary absurdity? Is the AHA stupid?

There may be many reasons, but one very suspicious fact becomes immediately obvious when you realize these endorsements product a substantial revenue source for the AHA, since companies must pay for the right to use the heart-check approval mark. Also, just look at the major contributors (millions of dollars) to the AHA: ConAgra, General Mills, Kraft, etc.) You get the picture.

Does this make the AHA evil? Not necessarily. But it seriously erodes credibility. it also should make you very leery of any advice that comes from such an agency that is reluctant to bite the food manufacturer hands that feed it.

In my view, we simply cannot rely on the AHA for genuine, unbiased heart health advice.

    I completely agree.  The ADA is just as terrible with their horrible food recommendations.  But it does harm people, people are being told over and over that "whole grains" are healthy and so they eat them, and they're not healthy.

    Dr. Davis, I haven't read much from you about dairy products.  That's another food group getting pushed at us by everyone, yet I read recently about casein in dairy products causing LDL cholesterol to oxidize.  Do you have any input on that?

    I remain undecided about dairy products.
    Several issues need to be factored in:
    1) Current day dairy products are not what they used to be--livestock are fed differently, often live on life-long antibiotics and growth-enhancing agents.
    2) Glycemic index--I have a personal problem with this. I have eliminated virtually all dairy products except fermented cheeses, and low-fat cottage cheese and yogurt in small quantities and I can tell a marked difference in the way I feel.
    3) The oxidation-antioxidation issue, in my mind, provides more fuel for supplement sales than real opportunity for meaningful treatment. Until we have some feedback that antioxidation strategies provide real advantage, I remain undecided about the real value.

    All in all, I am uncertain of how large a role dairy products should play. There's such a range of products from highly-processed yogurt in squeeze bags that are little more than chemiclals with sugar, to tradiational fermented cheeses rich in vitamin K2.
