Grapefruit - wonder fruit!

I think that grapefruits helped my mother live a good, healthy life till her death from loneliness and heartbreak at 83.....(ever since her husband died she just did not want to go on without him).
On reading an article from FOOD.GATHER.COM , I`m even more convinced about its health benefits as my mother had half a grapefruit every day for as long as I can remember! Here is the article entitled "Grapefruit Enhances The Liver's Ability To Remove Cancer-Causing Toxins".

I was interested to find out that grapefruit is not only a excellent source of vitamin C, but this fruit also helps eliminate toxins including carcinogens. Below is an explanation from The World's Healthiest Foods of how grapefruit helps our liver do this important work.
"Grapefruit juice significantly increases the production and activity of liver detoxification enzymes responsible for preparing toxic compounds for elimination from the body.
The liver clears out toxins, including carcinogens, using a two step process called Phase I and Phase II detoxification. In the first part of this process, Phase I, enzymes belonging to the cytochrome P450 family, work on the toxin to make it more attractive to enzymes involved in the second part of the process, Phase II. Unfortunately, the action of Phase I enzymes often renders the toxin not only more attractive to Phase II enzymes, but even more dangerous, and some foods contain compounds that only increase the activity of Phase I without also turning up Phase II.
Grapefruit increases the activity not only of the Phase I enzyme CYP1A1, but also that of NAD(P)H:quinone reductase 1, a Phase II detoxification enzyme that protects cells against oxidative stress and toxic quinones.
The end result: grapefruit works in both Phase I and Phase II to enhance the liver's ability to remove cancer-causing toxins."
*Check with your healthcare practitioner about consuming grapefruit juice if you're taking pharmaceutical drugs.

So although it's sour or tart or whatever you want to think... have it ..It's good for you !
