Anticancer Spears

.

Kevin Bell asked: "Any info on the email going around that Asparagus is good for curing cancer? This also seems incredulous, the pharma industry are not stupid and would be onto it quickly enough if there was any credibility in it."

Well, yes, I think you nailed it yourself, Kevin.

If there was any truth in it, it wouldn't be being sold at $4 a bunch at Woolworths.

As I understand it, cancers are initiated when your body loses the plot with regard to cell regeneration and starts an uncontrolled multiplication. 

I can see no reason why a food, any food, would stop this.  I would be more inclined to believe that eating excessive amounts of asparagus would cause problems rather than the reverse.

Too much of anything is bad.

But moderate amounts of asparagus with a good home-made hollandaise sauce is not bad for you and, indeed, can improve your emotional well-being no end.

By the way, I haven't seen the email that you mention, but I am sure that the miracle chemical in asparagus will be Rutin.  Love the name.  It is a naturally occurring flavonoid found in a number of foods.  As well as in asparagus, it is also in buckwheat, citrus peel, mulberries and cranberries.  In canned asparagus it appears as white or grey flecks in the spears.  Something about the canning process triggers crystallisation.  Quite beautiful crystals under the microscope.

Cancer and spices.

Anonymous asked: "Do ginger, curry powder and cumin powder help reduce risk of any cancers? "

Will anything prevent cancer?

No, probably not.  Cancer is not one disease but a diverse group of illnesses, all characterised by uncontrolled cell growth.  Cancerous cells are being produced all the time and the body deals with them.  The problems arise when the body can no longer deal with them.  This will be partly why cancers are more prevalent in the elderly; the body’s defences get weak, lazy or ineffective.

I believe that pretty much anything will cause cancer – if the body gets swamped with any chemical, systems can go awry.

But will anything prevent cancer?   I don’t believe so.  At least not any one thing.

Good diet and good health seem to be part of the cancer preventative thing :  be healthy, give your body a chance.  Let your body function as it should, defences work properly, cell reproduction work reliably.

I have little doubt that the individual components of ginger, cumin and curry powder will trigger cancers if taken in excess.  Anything taken at a level that distresses the body increases the likelihood of the body malfunctioning and cancers being the result.

But I really have no knowledge on compounds, natural or synthetic, that may directly work to prevent cancers.  And I think it unwise to pin your hopes on a 'silver bullet'.

I'll drink to that!

You are not going to want to read this: chocolate cannot be relied upon as a source of antioxidants to boost cardiovascular health. But it gets worse: drinking coffee and red wine in the hope it will prevent heart disease doesn't work either.

Why am I not surprised?

Have I not said from day one (of this blog) that there are no silver bullets?

Note: I do have to be careful - the reports in the media are exactly what I expected to be the case so the temptation to be uncritical is high.

But really why should anything be a silver bullet? We, as animals, have evolved along with the plants. Some we have leant to eat safely. Some we have learnt will kill us and should be avoided. True, there may be some plants which have beneficial properties but it is pure fluke and certainly there is no reason to think that, if a little is beneficial, a lot will be more so.

Even red wine.

Hot and cold on Cayenne

medavinci asks "Is it true cayenne pepper can lower blood pressure and open arteries? Can you just sprinkle it on your food or should it be cooked like curry to avoid salmonella? "

OK, a two part question:

Part 1. Is it true cayenne pepper can lower blood pressure and open arteries?

Maybe. Certainly many foods have physiological effects. A peek on the internet finds a squillion and one sites selling the benefits of cayenne pepper (as well as selling the cayenne pepper) but I couldn't find any mainstream sites, just the herbal fringe. This always makes me suspicious. But I have no reason to doubt that it MAY affect blood pressure. In either direction.

Opening arteries is a little more serious. Certainly people can get flushed in the face after eating peppers, chillies and such like. Is the the same as 'opening arteries'? Maybe. Is it desirable to look flushed? Possibly not. Is it the same as unclogging arteries from too many fries over a lifetime? No.

Maybe it works, maybe it doesn't. By the time you find out, the purveyors of fine herbal remedies will be telling you to eat, drink, roll in something else. But, if you feel that it is good for you, then it is. Isn't it?

Do be aware of the possible risks associated with cancers, especially mouth cancers, from excessive and prolonged consumption of irritants like chilli and pepper.

A rule of thumb that I always have with herbal remedies (like the one in this morning's paper that said magnolia flower tea cures hayfever) is a very simple question: if this cure, cayenne pepper, is so good and so effective, why are the major pharmaceutical companies not growing broad-acres of the stuff? These guys are pretty keen to corner the consumer dollar and never slow to see an opportunity.

Could it be that the efficacy of cayenne hasn't been proved to the level of certainty required by good science and the auditors of the Therapeutic Goods Act?

Remember: Alternative medicine that works is called... medicine.

Part 2: Can you just sprinkle it on your food or should it be cooked like curry to avoid salmonella?

If you are consuming it immediately it will be safe to take 'raw' as it were. If you are putting it into something warm, moist and nutritious and not planning to eat it for a few hours, cook it first.

The Silver Bullet School of Nutrition.

.

This is a previous post from "A Curate's Egg" but one which rightly belongs here and, in part, answers Kris loves Chocolate's question about which food are the healthiest for us.


I am not a fan of the ‘silver bullet’ school of nutrition.

By silver bullet, I mean the belief that some foods that are super foods.

Granted, some plants will kill you. That does not automatically mean that, in an effort to maintain even-handedness in the universe, there are some plants out there that are designed to save you.

But people seem to like wonder foods. Every year we hear about some berry, root or leaf from some exotic location that the native people know about and it keeps them happy, healthy and fucking like a hamsters, until they die of sexually induced exhaustion well into old age.

Oddly, these wonder foods seem to be most often sold by some multi-level marketing crowd.

Always, my first question is always the same: If this product is so good, why aren’t the pharmaceutical firms growing it, refining it, and mass producing it? Quinine was an example of where that did happen.

The problem with some of these wonder foods is that they are not supposed to cure a specific (and hence measurable) illness, such as malaria, but are generalists. They will stop cancer, aging, heart disease or some other intangible thing. Yes, death rates are measurable but you must keep an eye on causality. What’s that? The Hellarwi tribe never got heart disease AND the ate the wacko berry every day. Great! Perhaps the fact that they spent the day running around on foot and didn’t have an ounce of fat on them played a part too.

And the small matter of crocodile induced mortality.

Mind you, the crocodiles who eat the Hellarwi live to a ripe old age.

If you drink $40 worth of exotic berry juice a day and never get cancer, how do you prove it was the berry’s doing?

Perhaps you just weren’t going to get cancer anyway.
