Fish Oil, Plant Omega 3s, and Cardiovascular Health
The is some evidence that fish "omega 3"oils are beneficial to cardiovascular health. Less evidence that plant source "omega 3" has the same value. (Note: there are three types of "omega 3" or "n-3 fatty acids": two from fish - eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) - and one from plant sources - a-linolenic acid (ALA) found in walnuts, flax seeds and chia seeds.
Is there more (though controversial) evidence for fish (EPA and DHA) than for plant ALA because there's been more research? Probably. Wikipedia says, "The 18 carbon [ALA] has not been shown to have the same cardiovascular benefits as DHA or EPA." Note, they say "has not been shown to," and not "has been shown not to."
One of the studies I've found (on-line) found that an experimental walnut diet lowered total cholesterol and LDL cholesterol concentrations, while a fish diet resulted in decreased serum triglyceride and increased HDL-cholesterol concentrations. So both are valuable and may complement each other. (Though another author says that there is no data on the potential therapeutic benefit of EPA, DHA, or ALA supplementation on those individuals who already consume a vegetarian diet.)
So, there just hasn't been that much research and so many authors are hedging there bets: "Observational data suggest that diets rich in EPA, DHA, or ALA do reduce cardiovascular events, including myocardial infarction and sudden cardiac death; however, randomized controlled trial data are somewhat less clear;" and " The evidence [for plant sources, alpha-linolenic acid] is not as compelling as for fish oil."
I'm a cardiac patient,
and I'm a vegetarian, and for now I'm just eating a lot of flax (freshly ground),
chia, and walnuts.
I heard on the radio (and then googled) that St. Johnswort stimulates the liver to deal with toxins (see immediately below), which is why it can be tricky with many pharmaceutical drugs, because it helps the body get rid of them... so, St. Johnswort for detox! (take the tincture or tea).
St. Johnswort cause the production of an enzyme, PXR, which causes the production of a cytochrome P450 (which is a major detox vehicle) that gets rid of "xenobiotics"(i.e. unnatural chemicals): it increases the metabolism of the detox system.

From vol 3 no 1: An interesting clipping that
I've stumbled on since the last letter concerns vibration:(Globe and Mail, 13
June 2006) "SCIENTIST GETS VIBES TO BUILD BONES. Device to help space travelers
approved to treat sufferers of osteoporosis." The device is a machine that
generates vibrations - vibration implies acceleration/deceleration, and is therefore
somewhat like gravity - therefore in theory, and it seems in practice, good for
maintenance of bone mass in zero gravity (it was designed for use in space). On
earth, the article says, "a person who stands on [the platform of the vibration
device] for 20 minutes a day can build bone density an average of 2 percent a
year. ... By sending small vibrations through the body - moving about 50 micrometers
(or the thickness of a few human hairs) up and down and repeating at a rate of
34 cycles per second - the platform triggers musculoskeletal stimulations that
naturally occur... the vibrations from the platform are set to a frequency that
[generates acceleration that] is one-third that of gravity... and is therefore
safe. Other devices (exercise machines) which generate 4 to 15 gravities are dangerous,
we are told. |
The thing that I find interesting here is that a relatively subtle vibration is having an appreciable (positive) effect on body metabolism and function. I am therefore wondering what the vibrational effects of chanting, OM, for instance, are? We'd need an engineer to tell us about the difference in order of magnitude between that devise and the vibrations that are set up in your body by, a) a rock band in a bar, b) by chanting, OM for instance. However, orders of magnitude might or might not be of relevance here. Subtle vibrations may be having physiological effects. One would have to look and see.
Meanwhile, the safe course would be to do the chanting. It's bound to have salubrious effects at many levels (if not bone mass and muscle mass - muscles, that too was in the article). ("Salubrious" = health promoting - forgive the use of a relatively obscure word.) "Over all the bone density of the controlled group (the reporter has got this wrong - he means "experimental group" as compared to the control group) increased by 3 percent during a year, and muscle mass improved by 4 percent."
get chanting, OM (or what you fancy).
