Prehistoric Brain Tonic

Good news for health naturalists: Ginkgo biloba extracts have shown promise as both pre and post-stroke treatment in mice. We have all heard of ginkgo’s ability to improve blood flow to the brain, thereby enhancing memory and concentration. What better to help with stroke than a substance that increases blood flow to the brain?

A study out of John’s Hopkins University showed that mice given ginkgo before a stroke suffered only half the damage than mice not given the substance. And mice that received the extract five minutes following stroke had 60% less damage than mice not receiving it, while mice receiving ginkgo 4.5 hours following stroke had a third less damage. Wow! That’s incredible.

Researchers attribute ginkgo’s benefits to raising levels of heme oxygenase-1 (HO-1), an enzyme that acts as an antioxidant protecting cells against free radical damage. Free radicals are toxins that can damage DNA leading to aging, degeneration, and cancer.

Ginkgo is one of the top five highest-selling medicinal herbs in the U.S. Ginkgo biloba is a living fossil–it is the lone surviving species of an ancient order of trees which died out millennia ago. It grows wildly in Eastern China and has long been used for its medicinal properties.

I’ve never taken Ginkgo, but I must start. I just can’t ignore all the many benefits it seems to offer. Since I’m into the power of my mind, why not an occasional tonic? I say occasional because I think it’s always good to practice prudence when it comes to taking herbs or tinctures. But every once in a while can’t hurt, now can it? Not according to this latest study. I do want to caution, though, that this study is preliminary, and extrapolating the findings to humans may be premature; but like I said, I just can’t ignore all the positive press this herb has been getting. So I’ll keep my eyes open, and my mind too; and I’ll keep you all informed.

Red Wine for a Better Life

Well, it’s official: Red wine makes life better. You heard it here first. Drinking red wine officially improves life, but not in quantity. So says a new study from the US National Institute of Aging.

According to the study, resveratrol, an antioxidant found in red wine, slowed the aging of the heart, bones, and eyes in mice that were fed an otherwise healthy diet. Scientists hope that we might be able to extrapolate these findings to humans, but maybe we better not jump the gun just yet; so let’s simply proclaim that red wine makes life better for mice…for now. Now I wonder: would that be all mice or just our French furry friends? Oui, oui Monsieur souris, jouir d’une bonne santé.

If the findings can be extrapolated to man, then, this is great news for sommeliers–red wine is a blessing for better health. The study did not show any benefits to longevity, though, despite the hinting of such from an earlier study. In a 2006 study, researchers found that resveratrol, a compound found naturally in foods like grapes and nuts, improved the health and increased the life expectancy of overweight, older mice; however, not this time.

Well, either way, it’s good news. Scientists point out that the effects of resveratrol mimic the effects of calorie reduction, the most effective way found to date to minimize the effects of aging on mammals. If you’ve read The Six Keys To Optimal Health, you know what I’ve said about caloric restriction without malnutrition.

So if you want to slow down the aging process, reduce the quantity of food you regularly eat, and enjoy a glass of red wine with dinner. If that doesn’t keep you looking and feeling youthful then at least it should make cheese more enjoyable.

Bright Light and Vitamins Help Dementia

What’s the best thing you can do for a loved one suffering from dementia? Open the shades and let the light shine through during the day, and give them melatonin supplements at night. This according to a recent study out of the Netherlands this month. The research, conducted at the Netherlands Institute for Neuroscience in Amsterdam, showed that increasing light exposure, either from the sun or from fluorescent lights, along with nightly melatonin supplementation, helped elderly people suffering from dementia improve their sleep, mood, and overall well-being.

The study looked at 189 elderly Dutch women who were split into groups according to whether they were exposed to bright lights, given melatonin supplements, or both. Other groups were given standard Alzheimer’s medication, while others were given nothing at all. They then looked at various mental factors such as cognitive function, mood (as in depression and agitation), and sleep function. The researchers found that the group receiving bright lights and melatonin fared as well as those on the Alzheimer’s medication. Considering the side effects which usually accompany the medication (nausea mostly), these findings offer a great deal of encouragement.

I find this study especially interesting as I believe we can extrapolate these observations to the general population. I highly advocate both regular sun exposure and melatonin supplementation for overall health and well-being. Think about it: the source of all energy in the solar system is our sun. Every plant, animal, microbe, fungus or algae needs energy either directly from the sun, or by consuming another energetic life form. Either way, the energetic chain begins with the sun. Nothing could survive without the life-giving force of our primary star. So why would anybody avoid it? Yes, I know: skin cancer propaganda is at its highest–dermatologist need to market too–but we all need sunlight, plain and simple.

Melatonin is a naturally produced hormone that helps regulate our circadian rhythms, or our sleep cycles (you’ve read about it in The Six Keys To Optimal Health, right?). It is also a great natural remedy for insomnia. Melatonin has many other non-sleep related benefits. For instance, it has antioxidant properties. It has also been studied as a therapy against certain cancers. And it has also shown promise as an agent to boost memory and learning ability. Throw this in with the current findings on dementia, and what you’ve got is a very useful little substance.

One does need to be careful with both sun exposure and melatonin, though. Obviously, too much sun-worship can cause serious health problems. And taking melatonin every day can cause dependence, nasty withdrawals, and sluggishness when taken in too large a concentration. So I recommend taking it a couple time a week only, and then laying off completely for longer stretches, like say a month or so. Other than that, both practices should be highly beneficial and therefore done by everyone.

Stinky, Yet Effective

There’s an old Yiddish saying, “A nickel will get you on the subway, but garlic will get you a seat.” How true that is. Garlic, that sweet, succulent spice–also known as Allium sativum–just melts in your mouth and makes every dish delicious. Yes, in some people it can cause malodor; but the benefits of eating garlic far outweigh its pungent effects.

This miracle herb has been the subject of folklore and legend, and it’s home remedy uses are very well known. But new research shows exactly why garlic is so beneficial–it boosts the body’s production of a compound that relaxes blood vessels, increases blood flow, and prevents blood clots and oxidative damage. The compound, hydrogen sulfide (H2S), is produced by blood vessels and red blood cells when they come into contact with the chemical constituents of garlic. The exact compound causing the release of H2S is as of yet unknown.

The fact that we do not yet know which chemical component causes this incredible health benefit illustrates a very important point–one which I very adamantly stress in my upcoming book, The Six Keys To Optimal Health–and that is: It’s always better to eat whole, natural foods than rely on man’s synthetic versions. And the reason I give is precisely because we don’t always know which constituents do what. Moreover, we don’t know if compounds must work in conjunction with one another or if several work within the same biochemical pathway. Therefore, you gotta eat the real deal.

Saying that, we do know the effects of some of garlic’s constituents. For example, Allicin, which gives garlic its hot, burning flavor, has powerful antibacterial and anti-fungal properties. It also helps fight arteriosclerosis, dissolves fat, and is a mild antioxidant. Another compound, Beta-sitosterol, lowers blood cholesterol and may be useful in fighting benign prostatic hypertrophy (BNP). Garlic also contains calcium, folic acid, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. And to top it off, garlic is rich in vitamins B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), and Vitamin C.

Wow! Now tha-sa powerful.

Don’t You Just Hate When Mom is Wrong?

Just another blow to conventional wisdom: A review of 30 published studies confirms it even further – vitamin C does nothing to fight the common cold. I know, I know, that’s not what Mom said. Take plenty of vitamin C along with chicken soup and you’ll beat that cold in no time. Also, don’t go out with your hair wet or without a jacket, you might catch cold. Didn’t mom tell you that one, too?

Well, I hate to be the one to discredit Mom, but researchers at the University of Helsinki, Finland looked at people who took high-doses of vitamin C and found it did very little to reduce their risk of catching a cold (so small as to be clinically useless). Furthermore, it did nothing to reduce the duration of a cold or its symptoms.

That doesn’t mean vitamin C is useless, though. As I point out in my upcoming book – The Six Keys To Optimal Health – this nutrient is absolutely essential to achieving and maintaining great health. Vitamin C is a natural antioxidant, so it fights oxidizing free radicals, which can lead to aging and the development of many degenerative diseases, like cancer. It’s also an important player in the formation of collagen, so…that means healthy skin and healthy blood vessels and healthy joints and healthy ligaments and on and on and on. I think that vitamin C is so important that I believe, to have truly optimal health, you need to supplement with 1,000 mg per day.
But don’t feel badly for mom. She’s right about the chicken soup thing. I guess one out of two ain’t bad, now, is it?
