Liver cancer and protein: Why bother?

[Guest guest]

Why would you be willing to make major changes in your diet to possible reduce liver cancer risk, given that this is a rare cancer (incidence about 1 in 16,000) and that much of it appears to be associated with hepatitis? I don't think I'd be willing to do anything at all to change my risk of suffering something that rare. __________________________________________________

Hi :

I would be interested to know the source of your statistic that

*incidence* of liver cancer is 1 in 16,000. My understanding is that

in the US it accounts for 1.5% of all cancer *deaths*, which in turn

are about one quarter of all deaths.

Also, there do seem to be other good reasons to restrict protein

intake (methionine for example, as has been discussed here in some

detail). And if protein is so successful, apparently, at feeding

liver cancer I would be concerned that it *might* also be good at

feeding some other types of cancer. But it is possible that it is not

the protein itself that is the problem but some trace non-protein

substance accompanying the protein in the food.

Based on what we know now, I am not suggesting reducing the intake of

any amino acid, or total protein, below recommended

levels ........ but wondering if it might be wise to try to

restrict some of them to no more than the RDA, and avoid going hog-

wild on the high side.

In CR we have to restrict calories of some kind. So we have to try to

decide which it may be best to dispense with. Clearly we do not have

all the answers, so posting papers that have relevance to this issue

will be very helpful.

Research has so far only barely scratched the surface of this topic,

and we will know a lot more ten years from now. Hopefully.

Rodney.
