I know the suspense has been killing you! In part one we discussed the background on soy foods and breast cancer and the fact that there is no conclusive evidence either way for soy.
We discussed the facts regarding lifestyle and breast cancer risk and with no further ado, here is the rest of the information on soy foods and breast cancer:
2. Understand the Current Theories.
Although numerous studies claim positive effects of soy foods on cancer risk, other studies have found no effects, or unwanted effects. The key to this topic is that processed soy supplements may show activity that is not present in natural foods made from soybeans or soy flour (such as those consumed in Asian diets).
For hormone positive (ER or PR) breast cancer survivors, experts are not sure if soy fights with estrogen in the body to lower the chance of the cancer returning, or increases that chance by working with the estrogen. Some say one to two servings per day, the average amount eaten safely in Asian culture, is probably safe for survivors. Others are more cautious, and recommend three to four servings per week.
For those looking for cancer prevention, timing of soy intake also may be of importance to cancer risk. The association between consuming soy in childhood and reduced breast cancer risk has been observed in Asian-American and Chinese women. However, animal studies suggest that adult exposures to soy may not provide the same protection.
3. Decide What is Best for YOU!
Now that you know the facts, the choice is up to you! There is no one answer for everyone, it is your job to evaluate your situation, the facts and theories and decide. Of course, you always have the right to change your mind later with more research!
For me, I enjoy soy foods like soymilk, tofu and soybeans on a regular basis for 2 reasons.
- I like how they taste!
- It is a great source of plant protein that provides my body with many cancer fighting phytochemicals.
What’s your choice?
