I drink it every day, have for years, for the lycopene (antioxidant!) and
Vit C, and now comes this study saying it can "cause" BC and that if you've
already had BC (E+) and are taking AI, you shouldn't go near a grapefruit.
so ironic, here I thought I was saving myself. same with soy, which I ate
every day for years. and now this. it's really too funny. my brother the
scientist says pish tosh, it's not conclusive evidence, have the juice and
live it up. I'll ask my oncologist next month. but who the hell knows any
more...now they're saying drink pomegranate juice and eat blueberries and
take resveratrol (which I do) and Vitamin C; before that it was grapefruit
juice and....oh heck, I can't remember.

I always feel suspicious of any new fad that tells us that concentrating
any one particular foodstuff in our diet will improve our health.
History says they don't last.  It's relatively easy to show that
particular foods are harmful in some way, a lot harder to show that
something is beneficial in excess, especially where the claimed benefits
are specific such as reducing cancer risk.

It's easier to show that say, whether people who eat a lot of grapefruit
live longer, but even that proves remarkably difficult to make stick - a
diet of olive oil and red wine won't make a couch potato into a
Mediterranean peasant, there are so many confounding lifestyle factors.

Indeed.

My tenet is that I shouldn't eat or drink anything because it DOES me good
but because I enjoy it and it makes me FEEL good.

I avoid grapefruit juice entirely because so many medications I have
been given state one cannot drink it while on the medication.  It
interferes with the ability of the drug to work, it seems.  I have never
read or heard about it causing bc though.  Could just be one of those
food myths that tend to go around at times.

that's interesting; so food is not a nutrient and for life sustenance, food
is...er...entertainment? recreation? Potato chips, I do enjoy; but man, I
wouldn't live on an exclusive diet of potato chips. For the flavor, I'd eat
cheap store-bought birthday cakes with those ghastly sugar roses and thick
butter frosting. but....well, I guess the "feel" good part is the clincher
there, because I don't "feel" good eating things I know are really bad for
me. so maybe it's a matter of semantics.

I definitely eat things because they supposedly do me good. Things I
wouldn't otherwise imbibe. I take vitamins now too, and I don't enjoy them
at all.

Both. It's to satisfy hunger (which makes one feel good) and provide
nutrient but that doesn't mean that one can't enjoy it too. I don't eschew
foods which aren't good for me (very good chocolates, dairy foods, wines)
but nor would I eat anything just because it was promoted as being good for
me. If I don't enjoy it I don't have it.

Mind you, there's not much I don't enjoy, provided it's well made with the
best ingredients.

I don't think I could eat a whole bag of those but I understand your point.
I couldn't eat a whole box of the best chocolates at one go, much less live
on it.

LOL! I feel sick :-)

Yes.

The only vitamins I take are part of the foods we eat, they abound in them!
And there are so many wonderful foods which ARE good for us, even though
they taste wonderful too :-)

There are also blanket health instructions about foods which simply can't
apply to everyone. For instance, I've been told by medics that I shouldn't
drink the amount of tea I do. What they don't consider is that I don't drink
traditional tea which looks like tar, our tea is so pale that it looks like
water when it's poured. I reckon that our intake of whatever in tea is
considered bad for us is almost nil. Perhaps we have one daily 'allowance'
in a week but try explaining that to an enthusiastic adviser :-(

By the way, we have a half grapefruit every Sunday morning, it's part of our
ritual of special 'cooked breakfast' - which in our case is toast. The very
best bread, marmalade, lemon curd, rose petal preserve all made by me with
excellent ingredients (eggs and roses grown here) and various honeys made by
my bees. We enjoy it, and the coffee which is a morning ritual every day,
just once a day, the finest tasting coffee and unpasteurised cream. Bliss!
the better the day, the better the deed.

Good for us? No idea, we're still alive and kicking and have survived some
big health issues. I doubt that they were caused solely by our diets but
some things aren't worth giving up just to survive longer.

The government keeps telling us to eat more fruit and veg.  Well I do
eat more, but I keep on seeing adverts telling us to eat more. They
don't tell me when I should stop eating more, when I've got enough. Or
whether that should be as well as chocolate or instead of chocolate.

They also keep telling us to turn the central heating down by one degree
to save fuel.  How many times am I expected to turn it down one degree,
and how many times can I before we freeze.

We love vegetables and fruit so much that we couldn't eat more - we get
full!

Eat vegetables with your meals. Eat chocolate at all other times as and when
you feel like it :-)

I've been to fuel saving sites and have been infuriated by this attitude.
Our thermostat is turned down as far as it will go, well below the lowest
marked temperature - 10C. The ch rarely comes on, this is a very well
insulated and draught-proofed house but we don't feel cold. Or if we do we
put on another layer - and no, we've never got to wearing overcoats and
gloves :-) We're not daft and like to be comfortable. The worst aspect of
these sites is that there's no opportunity to report this lack, it seems
that the lowest temperature they'll allow is 19C which, to us, would be too
warm.

I know that your house is different, everyone's is, that's really my point
about blanket information/advice.

I just returned from a week in London, England where instead of my
usual lo-carb diet I ate nothing but lovely English breakfasts, museum
sandwiches, Tesco sandwiches, Winchester Cathedral sandwiches, honey
yogart made with cream , pasta,  sticky puddings, and ginger chocolate
cookies, scones with cream.  I lost two pounds.  

I don't understand why people are always bedmouthing British food, it
is delightful and secretly burns calories.

grapefruit juice increases the chance of BC, or increases estrogen, or, god
knows.....
the studies are interesting but epidemiology is so soft it takes MANY
studies to do anything conclusive. Even the nicotine/tobacco indicting ones
were questioned for years.
some STILL question them.

Why do you stipulate the "United States" in your post, Pumpkin?  You
certainly can't believe that other nations do not have their own beliefs
in some sort of an omnipotent being and trying to get on that "onramp"
at death.

because the original poster referred to her location of residence, so I
referred to mine. I live in the U.S.

"Trice" is a cool name.

I meant to say, I also really LIKE it ;-) Pomegranate juice tastes really
really awful! ;-)

Has anyone heard  anything bad about eating dark chocolate?  Since I
practically live on the stuff.

I just know that "any" chocolate is great if one is depressed in my
opinion.  Better than Valiums any day!<g   Recently they were talking on
a particular news show about how good "dark" chocolate is for us but I
don't remember the show or "good in what way".  It was just a good
excuse for me to eat more chocolate so I didn't care about the rest of
the info.  But I do know it said something about "dark" chocolate being
better than the other kind.     I bet you are one happy gal, Marilyn if
you live on dark chocolate!<g
