Detox Diets: Cleansing the Body.
Juice Up Your Health
But Does Detox Really Remove Toxins?
In evaluating Page's detox
diet, Dillard says, "Certainly, the human body carries huge loads of
petrochemicals. We know people usually die with the full burden of PCBs they've
ever been exposed to -- from fish, animals -- stuck in their liver. DDT sticks
But can fasting remove these? "Theoretically, yes," he
says. "When fat is mobilized, anything that is fat-soluble should be
mobilized, too -- should, that is," Dillard tells WebMD.
Although there are no studies of juice fasts/diets, water
fasting does have some scientific evidence behind it -- "but very
scant," admits Strychacz.
In the book Triumph Over Disease, Jack Goldstein, DPM,
outlines his true story in overcoming ulcerative
colitis by sticking to strict water fasting and a vegetarian diet. Goldstein is one of very few people
who has tested his own tongue scrapings, urine, feces, even perspiration during
a water fast, Strychacz says. "He found that the contents [during a fast]
are different than normal -- that toxins like DDT do get removed."
Strychacz would like to conduct a study of fasting's effects on
atherosclerosis. "Look at Dean Ornish's low-fat diet. He claims not only to
arrest but actually reverse atherosclerosis. That's huge. I would argue that if
a low-fat diet will reverse it, then what about a no-fat diet?"
Some still consider fasting -- in any form -- to be "out
there." "When I review diets that are not based on science, the
question I ask myself is: Would I feed them to my family? In this case, the
answer is a clear no," says Susan Roberts, PhD, chief of the Energy Metabolism Laboratory at the Jean Mayer USDA Human
Research Center on Aging and a professor of nutrition at Tufts University in
But the psychological or spiritual effect can't be discounted,
says Dillard. "People love the idea of cleansing, of purification rituals,
going to the Ganges, to the spa. It has powerful psychological, religious,
spiritual meaning. That has its own positive effect on health. But we need to
separate that from saying this is science or good medicine."
