Nobody ever heeds my cancer fighting diet information, but here it is again.
"What are the benefits of the sulfur compounds found in cruciferous vegetables?
Broccoli, and the other members of the cruciferous family of vegetables, pack a powerful punch when it comes to cancer prevention. The cancer protective properties of crucifers such as broccoli, Brussels sprouts, cauliflower, cabbage, and kale are attributed to the fact that these foods contain substantial quantities of the phytonutrients called isothiocyanates, specifically two isothiocyanates called sulforaphane and indole-3-carbinol. Research indicates that sulforaphane has the ability to increase the capacity of the liver to detoxify harmful, cancer-causing compounds. Specifically, sulforaphane increases the activity of the liver's Phase 2 detoxification enzymes. These enzymes (which include glutathione transferases, NAD(P)H: quinone reductase, and glucuronosyltransferases) are well known for their ability to clear a wide variety of toxic compounds from the body including not only many carcinogens, but also many reactive oxygen species, a particularly nasty type of free radical. By jump starting these important detoxification enzymes, compounds in crucifers provide protection against cell mutations, cancer and numerous other harmful effects that would otherwise be caused by these toxins. Research on indole-3-carbinol shows this compound helps deactivate a potent estrogen metabolite (2-hydroxyestrone)that promotes tumor growth, especially in estrogen-sensitive breast cells. Indole-3-carbinol has been shown to suppress not only breast tumor cell growth, but also cancer cell metastasis (the movement of cancerous cells to other parts of the body). ..."
Broccoli and Cancer Prevention
The unique combination of antioxidant, anti-inflammatory, and pro-detoxification components in broccoli make it a unique food in terms of cancer prevention. Connections between cancer development and oxidative stress, chronic inflammation, and inadequate detoxification are so well-documented in the research that any food improving all three of these metabolic problems would be highly likely to lower our risk of cancer. In the case of broccoli, the research is strongest in showing decreased risk of prostate cancer, colon cancer, breast cancer, bladder cancer, and ovarian cancer. We expect that risk of other cancer types will also eventually be shown to undergo reduction from regular consumption of broccoli.http://www.whfoods.org/genpage.php?tname=george&dbid=45
"How Much Broccoli Is Needed for Cancer
Recent studies have also provided us with a much better idea about the amount of broccoli that we need to lower our cancer risk. At the lower end of the spectrum, it looks like an average of 1/2 cup of broccoli per day-only 22 calories' worth of broccoli! -is enough to provide some measurable benefits. Few people have broccoli on a daily basis. But a 2-cup serving twice a week would still meet this minimum average amount. It's important to remember how little this amount actually in within the context of one week's food. A person eating 2,000 calories per day would be consuming 14,000 calories per week. A 2-cup serving of broccoli twice a week would provide about 178 calories-only 1% of the total weekly calories! At the higher end of the spectrum, studies show that more broccoli might be needed to accomplish other cancer-preventing tasks. For example, one study showed significantly higher urinary excretion of potential carcinogens from well-done, grilled meats given daily consumption of broccoli in the range of 9 ounces (250 grams) per day. That gram amount corresponds to approximately 1.6 cups of broccoli on a daily basis. We've also seen a study showing that "generous" amounts of broccoli can help optimize levels of antioxidants in the blood, especially beta-carotene and
lutein. (Optimal antioxidant levels can help lower the risk of oxidative stress in healthy cells, which also helps lower their risk of becoming cancerous.) In this study, the term "generous" was used to describe consumption of broccoli in the amount of 3 cups daily. Once again, that amount would not be ridiculously high in terms of calories-3 cups would provide about 132 calories, or 6-7% of a 2,000-calorie diet. But it might be a greater amount that many people would want to consume on a regular basis.
For us, the bottom line here is not to treat broccoli like garnish. In recipes like our Asian-Flavored Broccoli with Tofu or 5-Minute Broccoli with Feta Cheese and Kalamata Olives recipes, we use 1 pound of broccoli to provide two servings. That's approximately 1.5 cups of broccoli per serving. There is no reason to shy away from 2-3 cup servings of broccoli when enjoying this cruciferous vegetable, especially if you want to optimize its cancer-preventing benefits. But make sure you're not simply "decorating" your plate with single broccoli stalk and floret.http://www.whfoods.org/genpage.php?tname=foodspice&dbid=9
