Nuts are in fashion, nutritionally speaking, especially for heart health. Now, a new study finds that if you eat a handful of nuts several times a week that may help lower your risk of cancer.
Study results on nut consumption and cancer prevention have been inconsistent. In this systematic review and meta-analysis published in Nutrition Reviews, the researchers evaluated 36 studies – both large population studies and clinical trials – examining the relationship between eating nuts and risk of cancer or type 2 diabetes.
By comparing people who ate the most nuts (typically at least 4-5 times per week) to those who ate the least (typically 1 time per week or less), the researchers found that the high nut eaters had 15 percent lower risk of cancer overall. In specific cancers, they found lower risk for colorectal, endometrial and pancreatic cancer. They did not find any significant difference for risk of type 2 diabetes. Continue reading
You may know these healthy foods, but can you recognize them under a microscope? In honor of Cancer Research Month, we’re highlighting some of our Foods that Fight Cancer with the help of Caren Alpert’s electron microscope photography.
How soy plays a role in breast cancer risk and recurrence is one of the most common questions we get asked. A large body of human research suggests eating tofu, soy milk and other soy foods in moderation safe. Now an animal study that may help explain what is seen in human research, shows that eating soy foods when young boosts the immune response against tumors, reducing cancer recurrence.
The study is being presented at the American Association for Cancer Research (AACR) annual meeting, and is not yet published.
Soy contains compounds called isoflavones that mimic the effect of estrogen. This raised concerns that it would stimulate breast tumors fueled by estrogen and may interfere with anti-estrogen treatment, such as tamoxifen. Early animal studies did find a link between isoflavones increasing risk of breast cancer. According to the news release, one reason may be that this early animal research used animals that do not have certain immune cells called cytotoxic T cells. These are among the cells that act against breast tumors. Continue reading
