Processed foods, calories and nutrients: Americans’ alarming diet

By Posted on Leave a comment on Processed foods, calories and nutrients: Americans’ alarming diet

If you’re like the average American, more than half of your diet is filled with processed foods. Many of these foods are full of added sugar and fat and contribute to overweight and obesity. This matters for cancer prevention, because obesity is linked to higher risk, and a healthy diet links to lower risk for many common cancers, as well as other chronic diseases like type 2 diabetes and heart disease.

A study published recently reports alarming results on how much of the super processed foods Americans are eating, and how that affects nutrition, calories and the overall healthfulness of our nation’s diet. Read more… “Processed foods, calories and nutrients: Americans’ alarming diet”

    Tea links to epigenetic changes among women, study finds

    Aging, your environment, and certain lifestyle choices, such as what you eat or drink, can modify your DNA, without changing its overall structure. This type of modification is called an epigenetic change, and can turn your genes on or off.

    A new study suggests that drinking tea may lead to epigenetic changes among women. Those changes could play a role in altering risk of certain diseases, including cancer. The study was published in the journal Human Molecular Genetics. Read more… “Tea links to epigenetic changes among women, study finds”

      HealthTalk: Flaxseed and Breast Cancer

      By Posted on 2 Comments on HealthTalk: Flaxseed and Breast Cancer

      Q: Does flaxseed protect against breast cancer or increase the risk?

      A: Flaxseed most often raises questions regarding breast cancer because of its compounds called lignans. These compounds, sometimes called phytoestrogens, have a chemical structure similar to estrogen. At first glance, it might seem that would increase risk of estrogen-sensitive (ER-positive) breast cancer, which is spurred by excess estrogen.

      However, research suggests these tiny brown seeds do not increase cancer risk and could even be protective.

      In animal studies of human breast cancer, flaxseed and lignans isolated from it reduce breast cancer development, slow growth of existing breast tumors and lower levels of several growth factors that promote breast cancer. Human studies are limited but suggest that if anything, including one to four tablespoons of flaxseed per day might reduce breast cancer risk, especially in post-menopausal women.
