Don’t be misled by some of the press reports on the supposeddangers of alternative medicine, such as dietary supplements andherbal therapies. The news media often mislead us on these issues,and I’ll present one example later. I am in the midst of watching myorganic garden grow (well not literally watching it, but slavingaway helping it along). There is something nourishing aboutgrowing your own food, and if you have any chance to do it, even to a small degree, I “heartily” recommend it.
Supplements and More for Heart Disease
In This Issue
Here is the rest of the story on heart disease, as promised in last month’s issue. For prevention, consider taking folic acid and vitamin B12, as these two vitamins lower homocysteine levels.
This is a substance in the blood that apparently damages arteries and leads to increased atherosclerosis. While many supplements help to prevent heart disease, some of them are very important for treatment once you have heart disease.
Coenzyme Q10 and L-Carnitine
Coenzyme Q10 is essential for the production of energy in every cell, in the membranes of the tiny engines called mitochondria. Itis especially abundant in heart muscle, and it is an excellent antioxidant, about four times more potent than vitamin E in some studies. Supplements can helpangina, shortness of breath, congestive heart failure, arrhythmias, and high blood pressure. CoQ10 alsoincreases exercise tolerance. Side benefits of taking coQ10 are improved immunity, increased generalenergy levels, and protection from free-radical damage associated with aging.
Although coQ10 is not really a vitamin because your body makes it, the amount you make declines withage and illness. The typical dose for treatment of heart disease is 100 to 400 mg daily, depending on theseverity of the problem. For prevention, I think it is a good idea to take 50 to 100 mg a day, especiallyif you are over forty, if you have any other illness, or you have a family history of heart disease.
Another supplement that helps the heart is L-carnitine. This derivative of amino acids is essential fortransport of fatty acids across the membranes of the mitochondria where they are used for energyproduction (this is how it works well with coenzyme Q10). When there is pain due to a lack of oxygenin heart muscle (angina), the level of L-carnitine drops dramatically, and the heart muscle switches toglucose metabolism instead of fat. As a result, more lactic acid is produced, and this makes the painworse. If there is enough L-carnitine available in advance, the pain is lessened, and the likelihood ofdamage to the heart is reduced. Although you normally produce L-carnitine, as with some otheressential substances the production declines with age. Supplements of L-carnitine are typically in therange of 500 to 1000 mg twice a day. Some athletes take even more to enhance stamina.

• A recent report in the New England Journal of Medicine was misrepresented in the news and even in the title of the article: “Urothelial Carcinoma Associated with the Use of a Chinese Herb.” Newsreports left the impression that a therapeutic herb caused urinary tract cancer. Even in the firstparagraph, the article makes clear that it was not the therapeutic herb, but a manufacturing errorsubstituting a known carcinogenic and kidney toxic herb for the one that was supposed to bepresent. The reporting appears biased. You do have to be cautious with the use of therapeuticherbs, which are valuable treatments but have some risks.

Healthy Summer Diet Tip
Summer is always a difficult time to cook, as few people want to spend time in an overheated kitchen.
I have two solutions – the first is to eat a lot of salads. I put in a wide variety of vegetables, includingsome corn and peas, plus two leafy greens (spinach and arugula, are my favorites in addition tolettuce), shredded cabbage, tomato, cucumber, scallions, and cilantro. Then I might add somemarinated tofu (Tofu Lin is one I like), and some organic hard boiled egg. I top this with some balsamicvinegar-flaxseed oil-pepper-thyme-garlic dressing. It makes an easy and cool summer meal. Secondis to quick stir fry some garlic, onions and broccoli with tofu–a quick cooking meal served on top ofsome brown rice. It is easy, and the quick cooking decreases the heat build-up in the kitchen.
