Red Wine and Marijuana against Alzheimer's?

Two new studies suggest that red wine and marijuana may help to prevent or slow Alzheimer’s disease and other age-related memory loss.

An article first published at on November 21, 2008, points out that at the November, 2008 meeting of the Society of Neuroscience in Washington, D.C., Ohio State University researchers reported that THC, the main psychoactive substance in the cannabis plant, may lower inflammation in the brain, and even stimulate formation of new brain cells.

And in the Nov. 21, 2008, issue of the Journal of Biological Chemistry, neurologist David Teplow of the University of California, Los Angeles reported that naturally occurring components of red wine called polyphenols can block the formation of proteins that build the toxic plaques thought to destroy brain cells. In addition, these substances can reduce the toxicity of existing plaques. Both actions can slow memory loss.

Neither of these findings surprises me. That marijuana has medical efficacy against a variety of conditions is firmly established scientifically, and the health benefits of moderate red wine consumption are also becoming clearer with each passing year. As of November, 2008, 15 states had laws with provisions for medical marijuana on the books, and I hope more states enact enlightened policies in this regard. In the meantime, if you enjoy an occasional glass of red wine, continue to do so as part of an overall healthy diet.

Omega-3 for Menopause Symptoms
If menopause has got you down, omega-3 supplements may help. A new study from Canada’s Université Laval found that these essential fatty acids helped boost the mood of menopausal and peri-menopausal women suffering from mild depression and psychological distress. (It didn’t work well with women who had more severe depressive symptoms.) What’s more, the omega-3s were as efficacious as hormone replacement therapy and anti-depressants in reducing the incidence of hot flashes, the researchers reported. The Laval team recruited 120 women age 40 to 55 for the study and divided them into two groups. One group received capsules containing a total of one gram of EPA, an omega-3 fatty acid, and took three per day for eight weeks. The other group was given similar looking capsules that contained only sunflower oil with no omega-3. When the study began, the women were having about 2.8 hot flashes a day. These dropped to 1.2 in the omega-3 group but only to 2.3 in the sunflower oil group. The study was published in the February 2009 issue of the American Journal of Clinical Nutrition and in the November 8, 2008 online edition of the journal Menopause.

Antioxidants for Hearing Loss
This hasn’t been tried in humans yet but animal studies suggest that a combination of beta-carotene, vitamins C and E and magnesium can protect against temporary hearing loss caused by noise. It also might prevent permanent hearing loss stemming from cumulative exposure to loud noise. Some 26 million Americans have noise-induced hearing loss. For their study, researchers at the University of Florida and University of Michigan gave the vitamins and magnesium to guinea pigs before exposing them to four hours of noise at 110 decibels (about what you would get at a loud concert). They checked the guinea pigs’ hearing afterward by measuring neural activity evoked by sound. The investigators noted that hearing loss due to noise is largely caused by production of free radicals, which destroy healthy cells in the inner ear. The antioxidants in the supplement scavenged the free radicals; the magnesium was added to preserve blood flow to the inner ear and promote healing. The findings were presented at the 2009 Midwinter Meeting of the Association for Research in Otolaryngology.

Best-Ever Tofu Burger
Slices of frozen tofu provide the "chewiness" associated with a truly good burger, and the dark marinade lends a "meaty" flavor and moist juices. This "burger" has all the character of its high fat cousin, without the guilt. Serve on sprouted rolls with tofu mayonnaise.

Healthy Aging Tip

Managing Blood Pressure: Consider Supplements. Dietary calcium and magnesium are linked to lower blood pressure, and people with hypertension may want to take supplements of these minerals as well. It’s also not a bad idea to take 200 mg daily of vitamin C, which has a role in regulating blood pressure.

Does anyone know how to supplement (the) body while I get off this medication? I have been on it for two years and have been challenged with depression all my life.
