From the AICR Research Conference
There’s a good chance that one of the vegetables on your Thanksgiving table is part of the Cruciferous family, a large group of vegetables packed with nutrients and other healthful compounds. Research has long linked cruciferous vegetables with overall good health, along with cancer prevention. Now, new evidence presented at AICR’s Research Conference last month helps explain why cruciferous vegetables may play a role in preventing cancer.
Cruciferous vegetables are all part of the Cruciferae or cabbage family, and it’s a large family. Vegetables categorized as cruciferous include: broccoli, Brussels sprouts, cabbage, cauliflower and kale, along with rutabaga, watercress, and bok choy. Although population studies are inconsistent, several studies have linked high cruciferous vegetable consumption to lower risk of several cancers, including lung, prostate and colorectal.
One major breakthrough in diet and cancer research occurred in 1992 when a Johns Hopkins University professor isolated sulforaphane from broccoli with funding from AICR. Sulforaphane belongs to a well-studied group of anti-cancer compounds called isothiocyanates (ITCs), and cruciferous vegetables are packed with ITCs. In laboratory research, sulforaphane, along with other ITCs and phytochemicals in cruciferous vegetables, leads to slower cancer cell growth and cell death in many types of cancer cells. And over the years, researchers have identified numerous substances in cruciferous vegetables that have shown anti-cancer potential (see chart).
Scientists at the Research Conference revealed several ways in which cruciferous vegetables may prevent cancer. Here are a few highlights:
As the research continues, stay tuned for more findings as to how cruciferous veggies affect our cells and health. But as scientists point out, there are multiple ways these vegetables, and their compounds working individually and together, play a role in preventing cancer.
That’s why, for cancer prevention, AICR recommends eating a variety of vegetables along with fruits, whole grains and legumes. Aside from their cancer-protective substances, cruciferous vegetables also may help fight cancer indirectly by helping with weight control. Like other vegetables, cruciferous veggies are relatively low calorie and can help fill you up. And with so many to choose from, there’s plenty you would probably enjoy.
