Cite one that explicitly says it's okay to eat
grapefruit during chemotherapy. Post a link and
I'll read it.

You interpret good advice as "paranoia" because
you are ignorant. You are not familiar with drug
clearance mechanisms or the interactions of food
with those mechanisms. You are not competent
to give advice on what foods to avoid.

I suppose you think these people are paranoid, too:

Grapefruit can block the activity of an enzyme
in the intestine that is involved in the metabolism
of certain medications. Because the medications can't
be broken down, blood levels may rise and become toxic.
Drugs that are affected include cholesterol lowering
medications, beta-blockers for high blood pressure,
some psychiatric medicines, immuno-suppressants, and
protease inhibitors. The only chemotherapy drug that
grapefruit is definitely known to interact with is
Vincristine. However, there are concerns about the
interaction of grapefruit with other chemotherapy
drugs based on our knowledge of the way they function.
If you regularly eat grapefruit or drink grapefruit
juice, ask your doctor or pharmacist about possible
medication and chemotherapy drug interactions. Other
citrus foods and juices, such as orange juice, do not
appear to interfere with medication metabolism.

St. John's Wort may decrease TORISEL plasma concentrations,
and grapefruit juice may increase plasma concentrations
of the major metabolite of TORISEL, and therefore both
should be avoided.

[Note that TORISEL brand temsirolimus is a cancer
chemotherapy drug.]

No concurrent dairy products or grapefruit juice
with temozolomide administration

[Note that temozolomide is a cancer chemotherapy drug.]

Grapefruits and grapefruit juice may increase
the effects of imatinib by increasing the amount
of this medicine in your body. You should not eat
grapefruit or drink grapefruit juice while you are
taking this medicine.

[Note that imatinib is a cancer chemotherapy drug.]


Here we have examples of a university medical school,
large pharmaceutical manufacturer, the U.S. government,
and the Mayo clinic all recommending not to drink
grapefruit juice during cancer chemotherapy.

There are only two possibilities: all of these
institutions share my paranoia, or you don't have
a clue what you are talking about. You hand out
very bad advice, and when confronted with the facts,
you persist in your bad advice without regard to
the harm you may do. People could actually die
because of your incompetent advice.
