Onions, rich in the antioxidant quercetin, and curcumin, the yellow spice found in turmeric and curry powders, have both proven to be powerful tools against the spread of osteoporosis and cancer.

The researchers in this study believed that curcumin was the more potent key, since the amount of quercetin they prescribed matched what patients typically eat every day, whereas the amount of curcumin consumed was many times what you would normally consume.

However, when you consume them in their natural state you also receive the benefits of the other nutrients in the plants that synergistically further improve the benefits they provide.

Although the researchers believe eating onions and curry alone may not help, it certainly can't hurt you. But also bear in mind that, if your body does not react well to consuming spices like curcumin, pay attention. Your body is a far better barometer of your health than anything you'll ever read.

So if you like curry, then by all means use it regularly in your diet. But if you don't like it, then don't worry, as there is no single "magic bullet" to defeat cancer. You can, however, fight and prevent colon cancer by following a number of safe, natural tips, none of which have anything to do with taking a drug:

1.  Avoid processed meats. The evidence seems fairly clear on this one. From my perspective, the less cooked the meat the better. I personally generally do not cook my meat as I believe that the cooking, not the actual meat, produces most of the health risks associated with it.

2.  Exercise.

3.  Eat vegetables.

4.  Get regular sunshine to raise your vitamin D levels.

5.  Eat enough omega-3 fats.

6.  Lose weight if necessary.

7.  Have your doctor check your C-reactive protein (CRP) levels and take steps to lower them if necessary.

8.  Maintain normal iron levels.
