Continuing the theme from my previous post on colon cancer, here's another study demonstrating that healthy food choices can make a difference for people with colon cancer. The American Society of Clinical Oncology (ASCO) reports that people with stage 3 colon cancer who ate at least 2 ounces of tree nuts per week, compared to those who did not eat tree nuts, reduced their risk of cancer returning by 46% and of death by 53%. This was an observational study, which means that researchers did not assign one group of people to do something and the other without the specific treatment, and participants also received chemotherapy. Ultimately, a study needs to be done where some people are assigned to eat nuts and others do not and compare those outcomes to understand exactly how much benefit is possible. Regardless, I think it is still worth it to eat nuts to help increase your health. For anyone, but especially during and after cancer treatment, it is important to choose foods that provide your body with the raw material it needs to function properly.
Be sure to read the packaging when you buy nuts and avoid inflammatory oils (canola, cottonseed, etc), added sugar or salt. Note that tree nuts do not include peanuts or peanut butter because they are a legume.
