Recently I went to Trader Joe's and found some products that I thought were a great way to fight cancer by eating healthy and avoiding toxins and chemicals, or "free radicals" which promote the growth and development of cancer. Here are some of my favorites:
Finally, Bacon without Nitrates. Also free of preservatives and MSG.

Heart Healthy, Organic Cereal with Blueberries (anti-oxidants) and fiber, which helps prevent colon cancer.

Nitrate and Nitrite free, MSG free all natural hot dogs. Avoid unnecessary toxins and free radicals.

These tasty whole-wheat crackers make a nice addition to soups, or just an easy, healthy snack, with fiber to help prevent colon cancer.

These all-natural whole-grain corn chips have a nice nutty flavor and are very addictive.

Dried Blueberries, with no preservatives or artificial chemicals, are one of the highest sources of anti-oxidants that help to fight against cancer.

This herbal tea gives a double punch of anti-oxidants, with both green tea and blueberries.

Here is a laundry soap we have tried which is free of phosphates and better for the environment, free of caustic chemicals.
For years I have been concerned about the overuse of artificial sweeteners. In nursing school over 22 years ago I remember learning about the dangers of sorbitol causing the clogging of small blood vessels and damaging nerves, particularly dangerous in diabetics, possibly leading to the loss of toes, vision loss and kidney damage. Since then I have avoided them. Recent studies have confirmed that there is link between several artificial sweeteners and cancer. Here is an article from the National Cancer Institute regarding the research on this topic:

Because fiber is useful in helping to prevent colon cancer (not to mention useful in preventing and
treating constipation), I began trying out different fiber cereals and fiber products to see what was the most helpful. In doing so, I was quite alarmed to find that many fiber cereals contain artificial sweeteners. I also found that most fiber laxatives did as well. Buyer beware! Please read the labels! Look for saccharin, aspartame, and sorbitol in particular. So far Splenda, Acesulfame potassium, Sucralose, and Neotame have not been linked to cancer, but I am still avoiding them.
Of all the fiber laxative powders that are out there, I have found Benefiber, made entirely of gluten-free wheat dextrin, to be the most gentle on my body, without using artificial sweeteners. The only disadvantage to it is that it seems that I have to use more of it to get the benefit, but that is a small price to pay for the good results and the reduced risk.
