Reader Question: Can Asparagus Fight Cancer?
A couple of days ago we received a question from a reader about green asparagus: Does this vegetable have cancer fighting principles? Let’s find out…
I have a fantastic book by Dr. David Servan-Schreiber, MD, PhD called The Anti-Cancer Way of Life. I frequently refer to it when I’m curious about certain foods. Asparagus is cousin to garlic and onions and presumably has the same cancer fighting sulfur compounds. The alliaceous family helps to “reduce the carcinogenic effects of nitrosamies and N-nitroso compounds.” These compounds arise with the overgrilling of meat and tobacco smoke.
Dr. Servan-Schreiber’s book contains charts that break down the effectiveness of certain foods to inhibiting certain cancers. Asparagus ranks quite high on most lists.
- Colon Cancer: 100 x inhibition in cell growth, #10 on list of foods
- Brain Cancer: 80 x inhibition in cell growth, #15 on list of foods
- Lung Cancer: 70 x inhibition in cell growth, #10 on list of foods
- Prostate Cancer: 70 x inhibition in cell growth, #21 on list of foods
- Breast Cancer: 70 x inhibition in cell growth, #15 on list of foods
These numbers are compared to cells that were not exposed to any vegetable at all. Asparagus seems to be ranked high on all of the above lists and has pretty super cancer inhibiting properties. The foods that ranked above it always included garlic, leeks, Brussels sprouts and the cabbage family vegetables. I think it’s safe to say that yes, asparagus has cancer fighting principles.
