Optimize Your Cells' Detoxification / Cleansing Ability

From the World's Healthiest Foods website

For about 20 years, we've known that many phytonutrients work as antioxidants to disarm free radicals before they can damage DNA, cell membranes and fat-containing molecules such as cholesterol. Now, new research is revealing that phytonutrients in cruciferous vegetables, such as Brussels sprouts, work at a much deeper level. These compounds actually signal our genes to increase production of enzymes involved in detoxification, the cleansing process through which our bodies eliminate harmful compounds.

The phytonutrients in cruciferous vegetables initiate an intricate dance inside our cells in which gene response elements direct and balance the steps among dozens of detoxification enzyme partners, each performing its own protective role in perfect balance with the other dancers. The natural synergy that results optimizes our cells' ability to disarm and clear free radicals and toxins, including potential carcinogens, which may be why cruciferous vegetables appear to lower our risk of cancer more effectively than any other vegetables or fruits.

Recent studies show that those eating the most cruciferous vegetables have a much lower risk of prostate, colorectal and lung cancer - even when compared to those who regularly eat other vegetables:

In a study of over 1,000 men conducted at the Fred Hutchinson Cancer Research Center in Seattle, WA, those eating 28 servings of vegetables a week had a 35% lower risk of prostate cancer, but those consuming just 3 or more servings of cruciferous vegetables each week had a 44% lower prostate cancer risk.

In the Netherlands Cohort Study on Diet and Cancer, in which data was collected on over 100,000 people for more than 6 years, those eating the most vegetables benefited with a 25% lower risk of colorectal cancers, but those eating the most cruciferous vegetables did almost twice as well with a 49% drop in their colorectal cancer risk.

A study of Chinese women in Singapore, a city in which air pollution levels are often high putting stress on the detoxification capacity of residents' lungs, found that in non-smokers, eating cruciferous vegetables lowered risk of lung cancer by 30%. In smokers, regular cruciferous vegetable consumption reduced lung cancer risk an amazing 69%!

How many weekly servings of cruciferous vegetables do you need to lower your risk of cancer? Just 3 to 5 servings - less than one serving a day! (1 serving = 1 cup)

To get the most benefit from your cruciferous vegetables like Brussels sprouts, be sure to choose organically grown varieties (their phytonutrient levels are higher than conventionally grown), and steam lightly (this method of cooking has been shown to not only retain the most phytonutrients but to maximize their availability).
