Mushrooms and Green Tea May Lower Breast-Cancer Risk

By Margaret Furtado

A recent study reported in the International Journal of Cancer suggests that women who eat large amounts of mushrooms and drink a lot of green tea may be at lower risk for developing breast cancer.

The research trial included more than 2,000 Chinese women, with 1,009 breast-cancer patients (aged 20-87) and an equal number of healthy women matched for age. Each woman completed a detailed dietary questionnaire citing specific foods consumed.

Do mushrooms and green tea affect breast-cancer rates?

The researchers found that the greater the mushroom consumption (both fresh and dried), the lower the breast-cancer risk. Those who ate the greatest amounts of fresh mushrooms (10 grams or more per day) were about 2/3 less likely than those who ate none at all to develop breast cancer. Subjects who ate 4 grams per day saw their breast-cancer risk fall by half.

Interestingly, the women decreased their risk even more if they also drank green tea daily. The breast-cancer risk of women who consumed both mushrooms and green tea was 11 percent, compared to 18 percent for women who didn't consume either food. The study used green tea, which is a "younger" tea but which still has caffeine.

No proof yet

While the researchers eliminated possible confounding factors, this study does not prove that mushrooms and green tea actually reduce a woman's chances of getting breast cancer.

Epidemiological studies, however, do show that in places where the Chinese people are still eating the traditional diet, breast-cancer rates are 4-to-5 times lower than those of most developed countries. (All bets are off if a Chinese woman has switched to eating a westernized diet.)

While this study has not nailed down a cause-and-effect relationship, it is the first to link high dietary consumption of mushrooms and green tea to reduced breast-cancer risk. In addition, those participants who ate at least 10 grams of mushrooms per day saw the greatest reductions in their risk.

So eat some!

Half a cup of raw mushrooms weighs roughly 35 grams, so a little more than 1/8 cup of raw mushrooms a day (about 8 or 9 grams' worth) might just help reduce your breast-cancer risk. Even an 8-ounce cup of raw mushrooms would add up to only 10 calories; therefore, a big helping of these tasty fungi might also help you feel fuller and lose weight. Adding green tea may be a good idea, too.

If you're a mushroom-lover or willing to try them, here are some tips:

• Look for mushrooms that are firm, unblemished, and free of mold or surface moisture (but not dry).
• Store pre-packed containers of mushrooms in airtight plastic bags in the fridge, so they'll hold on to their moisture and won't spoil so rapidly.
• Place loose mushrooms in a paper bag and then in your fridge.
• Squeeze some lemon or lime juice onto raw mushrooms to help them retain their color.
