Lowering Cholesterol Raising HDL

A recent article in the New York Times (An Old Cholesterol Remedy Is New Again, January 23, 2007) reported that a highly touted new drug designed to raise HDL-cholesterol levels failed in research studies, leading to increased cardiac disorders and higher mortality in those given the drug (torcetrapib) than those on placebo. The article went on to note that raising HDL is a very desirable goal, and the only way to do it has been known since 1975 – by taking high dose supplements of a simple vitamin – niacin (vitamin B3). (Other ways that they did not mention include aerobic exercise and supplements of policosanol, derived from sugar cane.)
The article pointed out that the particular beneficial effect of this versatile vitamin has been shunned by the medical profession, even though it is extremely safe and has a variety of other benefits. It lowers triglycerides and total cholesterol, and in that earlier study reduced heart attacks and strokes by 26 and 27 percent respectively. Perhaps the problem with medical acceptance of niacin is that it is safe, cheap, and effective.

Organic Strawberries Better

Berries are known to be high in antioxidants that protect against heart disease and cancer. Strawberries are among the most nutritious foods, but conventionally grown strawberries have some of the highest levels of pesticide contamination.
Recent research shows that the antioxidant capacity of organically grown strawberries is higher than conventional berries. This is in part due to more vitamin C content. (Olsson ME, et al., Antioxidant levels and inhibition of cancer cell proliferation in vitro by extracts from organically and conventionally cultivated strawberries. J Agric Food Chem. 2006 Feb 22;54(4):1248-55.)
The researchers incubated colon and breast cancer cells with extracts of the different strawberries. They found that the extract from organic berries inhibited the cell growth more effectively than extracts from conventional fruit. This might be due to the vitamin C content or synergistic action with other antioxidants contained in strawberries, such as ellagic acid, anthocyanidins, procyanidins, phenolic compounds, and flavonoids. These chemicals also reduce excessive blood clotting and improve circulation.

Grape Juice Equals Red Wine Benefits

Although most people know about the potential benefits of red wine for the heart, they are not aware that some grapes provide the same apparent benefits without the risks of consuming the alcohol in the wine. A new study from France shows that Concord grapes also contain the beneficial polyphenols found in wine (Anselm E, et al., Grape juice causes endothelium-dependent relaxation via a redox-sensitive Src- and Akt-dependent activation of eNOS. Cardiovasc Res. 2007 Jan 15;73(2):404-13).
The lining cells of the arteries (endothelium) produce nitric oxide (NO), a relaxing factor that improves blood flow by opening up the blood vessel. Synthesis of NO is dependent on an enzyme, and the polyphenols in grape juice enhance the activity of that enzyme. This was a lab study on artery tissue, and it showed that the benefits were likely due to antioxidant function of the grape polyphenols.

Telling Doctors about Alternatives

A recent survey by the AARP showed that most Americans over 50 use some form of alternative medicine, but they do not discuss it with their other doctors (Reuters Health, January 26, 2007). The authors noted that it is unwise not to inform a doctor of other therapies that you might be using, and this is true, but telling them may not be so simple.
Often when a patient does tell the doctor about their other therapies, they are met with resistance, disdain, and sometimes mockery. I know of many examples. Recently, a friend went to a compassionate group of doctors who usually understand the importance of patient communication. When she said she preferred to avoid statins, and that she was able to lower her cholesterol in the past with nutrients, she was met with icy dismissals from both of the doctors she saw there. This was in spite of the fact that she had had past side effects from statins. These reactions do not encourage further communication.
I suggested that she take supplements of policosanol and red yeast rice and follow her diet and have her cholesterol rechecked in a few months. Even with a strong family history, supplements along with the healthy diet and exercise are likely to make a significant difference in reducing her risks or cardiac disease.
It is still important to tell your doctor of any alternative therapies you are doing, especially supplements, but you should not be put off your own program without specific and documented objections. It is highly unlikely that you will harm yourself with nutrition and supplements.

Probiotics for Infant Colic

New research shows that friendly bacteria known as probiotics (such as lactobacillus) can help infants with colic (Savino F, et al., Lactobacillus reuteri…versus simethicone in the treatment of infantile colic... Pediatrics. 2007 Jan;119(1):e124-30). Although the infants can’t clearly report their symptoms, it appears that their crying and distress may be due to excessive gastro-intestinal gas.
In this research, an anti-stomach gas drug, simethicone, was compared to Lactobacillus supplements. For 28 days, 95 percent of the infants on the Lactobacillus were better compared with only 7 percent of those on simethicone. By the end of the 28 days, the infants on Lactobacillus cried only 51 minutes per day, compared with the simethicone group with 145 minutes of crying. This treatment could bring great relief to numerous infants, to say nothing of their parents.

Folic Acid for Hearing and Cognition

Supplements of folic acid help to reduce hearing loss associated with aging. In a study in the Netherlands, 728 participants between 50 and 70 years old received either supplements of 800 mcg daily or a placebo. After three years, hearing loss was significantly less in the group receiving the supplements. Because foods were not fortified in Holland at the time, baseline folate levels were lower among the participants than in a comparable US population, so it is unclear whether the same benefits would be seen here. However, folate is safe, inexpensive, and has many other health benefis, so it would not hurt to take supplements. (Durga J, et al., Effects of folic acid supplementation on hearing in older adults: a randomized, controlled trial. Ann Intern Med. 2007 Jan 2;146(1):1-9.)
In a related study, the researchers also evaluated cognitive function in participants on folate supplements compared with a placebo. After three years, sensorimotor speed and infor-mation processing were significantly better in the supplemented group. In both studies, homocysteine levels were reduced by supplementation.

Exercise and Diet for Obese Elderly

It is well known that age and obesity increase heart disease risks. In the obese elderly, a new study shows that it is never too late to benefit from starting lifestyle changes to reduce those risks. Researchers studied 27 adults over 65 years old with body mass index (BMI) over 30 (indicating obesity) for six months (Villareal DT, et al., Effect of lifestyle intervention on metabolic coronary heart disease risk factors in obese older adults. Am J Clin Nutr. 2006 Dec;84(6):1317-23).
Compared with the 10 controls, the 17 patients put on a diet and exercise program had an 8.4 percent loss of weight, a decrease in waist circumference, a drop in blood sugar, lowered serum triglycerides, and improvement in both systolic and diastolic blood pressures. The inflammatory markers, C-reactive protein (CRP) and interleukin-6 (both risk factors for heart disease) were also significantly reduced.
It is never too late to benefit from starting a health program. Of course, it is also never too early to start taking better care of yourself.
