Doctors Oz and Roizen Recommend 4 Herbs

In a recent newspaper article*, Dr. Mehmet Oz and Dr. Michael Roizen (Chief Medicial Officer of the Cleveland Clinic) recommend the use of 4 herbs as scientifically validated. They cite an article on the Cleveland Clinic Wellness website's Supplement Review which reports that the following popular herbs "are generally safe and have some scientific backing as effective remedies":

• Turmeric (Curcumin) for easing inflammation of ulcerative colitis in conjunction with standard medications
• Aloe vera cream "may work better than some prescription preparations" for healing mild skin burns
• Saw palmetto "for benign prostatic hyperplasia" (enlarged prostate gland in men); this herb seems to block the hormones responsible
• Garlic has moderate but good results in helping "control blood pressure and cholesterol, and slow down hardening of the arteries"

Fish Oil: Excerpts from a magazine interview with me

The balance of fatty acids in the body can promote inflammatory or non-inflammatory states. Higher amounts of omega-3 fats in the diet have been shown to modulate inflammation and keep it within healthy ranges. The various cellular and tissue damage that can occur from chronic inflammatory states are certainly not healthful. This basic mechanism of action implies a wide-ranging and powerful effect of omega-3 fats to support wellness. Additionally, these fats are part of brain and nerve structures, so they help to maintain the health of those tissues, as well.

Omega-3 and omega-6 fats have been called “essential fatty acids” since the body can’t manufacture them from other fats, as it typically can for other types of fat. The optimal ratio of omega-6 to omega-3 fats is somewhere between 1:1 and 3:1. The common American diet has been estimated to be over 15:1, a marked deviation from a healthy norm.

The benefits of most other non-omega-3 fatty acids in fish oil are not well-defined in the scientific literature. Fish oil naturally contains a range of fats, including cholesterol, triglycerides, and stearic acid. The ones that are considered less desirable, cholesterol and triglycerides, are sometimes removed from fish oils to further concentrate the omega-3 portion and allow higher strengths in fewer capsules.

All natural oils contain various mixtures of fatty acids in varying amounts. Omega-9 fats are best known as being abundant in Olive Oil, and are considered non-inflammatory and especially healthy if substituted for most omega-6 fats that are pro-inflammatory. Some natural oils are fairly well balanced, such as flax and hemp seed oils, or walnut oil. Others, like fish oil, tend to be predominantly omega-3. Most vegetable oils are mostly omega-6 fats and their predominance in the modern diet has been blamed for some of our poor health.

Some consumers do know about various sources of fish oil, and some have advantages or disadvantages. For example salmon is a favored source of omega-3 fats, though salmon oil typically contains less than other common fish oils. Traditional fish sources may be better accepted by those who won’t or can’t eat shellfish. The fisheries in Norway and Peru are among the best managed traditional fisheries on earth.

Krill, a small crustacean shellfish, is a unique source of omega-3 fats since krill also naturally bonds the fatty acids to phospholipids, which are essential for cell membranes and which enhance the bioavailability of the oil. Krill oil also contains the powerful antioxidant pigment astaxanthin, which is responsible for the color of shrimp and salmon. Krill is considered the best managed fishery in the world, with trained observers on each boat monitoring the harvest. The krill harvest limit can be rapidly adjusted to support a healthy population, and the total world harvest (most of which goes into pet foods) is only a fraction of the allowable sustainable harvest level.

Essential fatty Acids (EFAs) interview, Natural Products Marketplace magazine, January, 2011

The awareness of EFAs, especially the Omega-3 fatty acids EPA and DHA, is large and growing larger. The accumulating mountain of evidence and the endorsement by popular health “gurus” assures continued growth in this important product category. As the benefits of specific fatty acids for regulation of various healthy body functions – such as inflammatory processes, hormonal health, and maintaining brain/nerve/cellular structures – becomes even more well known, more and more people recognize the potential for EFAs to positively affect their health.

While there are combination products that deliver Omega-3, Omega-6, and Omega-9 fatty acids together, the focus has been more on specific sources such as fish or flax, along with some more unusual ones. Of course, natural oil sources are not comprised of a single fatty acid. For example, natural fish oil can not only supply EPA and DHA but also originally supplies ALA, cholesterol, triglycerides, and other fatty acids; though many of these components can be removed during processing to provide purer and stronger materials that are richer in EPA and DHA to require far fewer capsules to reach desired levels of these two fractions. Flax oil is best known as a vegetarian source of the omega-3 fatty acid ALA (alpha-linolenic acid), but ALA levels are only about 55% of the total; flax oil also contains about 19% omega-9 as oleic acid, 14% omega-6 as linoleic acid, and 12% saturated fats. The conversion of ALA to EPA is a significant metabolic hurdle. Women do this conversion better than men; people who consume the most omega-6 in their diets have a more difficult time converting ALA to EPA. Typically between 5% and 15% of ALA converts to EPA and about 2% to 5% of ALA converts to DHA, making flax a much more dilute and less certain source of EPA-DHA.

Fish oil is subject to environmental concerns related to both sustainability and contaminants. Manufacturers audit their suppliers and set strict identity/safety specifications to assure the quality of products.

Most fish oils are molecularly distilled to remove contaminants, manufactured under strict quality assurance standards, and screened to be free of potentially harmful levels of contaminants and heavy metals, such as mercury, PCB’s, dioxins, and others.

Other types of EFAs include Flax seed oil, Evening Primrose Oil, Pumpkin seed oil, Black Currant seed oil, Wheat Germ oil, Castor Oil, and Virgin Coconut Oil.

Purity, potency, and freshness are always the challenges with EFAs.

The trend is toward more concentrated products of higher purity that allow people to get their EPA and DHA with smaller quantities of capsules or less volume of liquid. Liquids and smaller capsule sizes allow more children and seniors to enjoy the benefits of fish oils, while high strength capsules better hit the main demographic in between.

All fish oil supplements are typically hundreds of times safer than eating a serving of fish in relation to environmental factors; and typical esterified products have the added benefit of being free of cholesterol and triglycerides, which are undesirable food components for those with high cholesterol. By far, most of the studies proving the health benefits of supplemental fish oils have been with the esterified (ethyl ester) form, rather than the triglyceride form found in cold water fatty fish. There is very strong science supporting the use of this form.

Esterified fish oils also have been shown to sustain human serum levels better than the triglyceride form, over both a 24-hour period and a one-month period, which better supports a healthy heart rhythm. Notably, the most concentrated products are available only as esterified fatty acids. The ability of a consumer to get the 1-3 grams daily of EPA + DHA recommended by many health experts is enhanced by modern formulas that concentrate these essential fatty acids into fewer capsules and smaller serving sizes with fewer undesirable components, thus increasing customer compliance with a healthy nutritional protocol.

Both triglyceride and esterified ethyl ester fish oils are available in the marketplace, and both forms have their advocates. In the body, both forms must first be digested, stripping off the triglycerides or ethyl esters and leaving only free fatty acids that can be readily absorbed. These free fatty acids are then combined with triglycerides present in the liver before entering general circulation; so the circulating form will actually be the triglyceride form, no matter which form of fish oil one consumes. Both forms provide great value and important nutrients for the consumer; but the triglyceride form has no more proven value than the ethyl ester form, despite some excessive marketing claims.

Cholesterol measures

Total cholesterol means nothing in terms of health. Just as many people have fatal heart attacks with low total cholesterol as high, and there are additional health risks if it is too low. Flipping a coin gives you just as good data. I have seen people whose total cholesterol is high but who seem to have little risk. There may also be a genetic component to the baseline total cholesterol number that defies easy changes.


The main relevant and meaningful cholesterol number today is the ratio of total cholesterol to HDL cholesterol (over 5 is not good; lower means lower risk). This means that, if you have high total cholesterol but your ratio is good, your HDL number is high and that makes you better protected than someone whose HDL is low. Routine blood screenings now tend to include this important number. Homocysteine is another number that indicates your risk of inflammatory conditions affecting the brain and cardiovascular system.
