If you’re a woman and getting at least 30 minutes a day of activity, that means a lower risk of colorectal cancer. Now a study published today suggests that women who exercised as teens for even an hour a week have a lower risk of dying from cancer in middle age and older compared to teens who weren’t active at all.
These women are also more likely to live longer overall, the study suggests, whether they exercised as adults or not.
The study included almost 75,000 Chinese women who were part of the Shanghai Women’s Health Study. The women were 40 to 70 years old and they had answered questions about their lifestyle habits currently and decades earlier.
After an average of 13 years, the researchers looked how many of the women had died overall, and whether the cause of death was from cancer or cardiovascular disease.
In three years, you won’t be seeing foods with added trans-fat on your grocery shelves, thanks to action from the federal government announced today. The step was taken primarily for heart health but it’s a great opportunity to help you shift to a more cancer-protective diet.
Trans fats are liquid fats that are partially hydrogenated, which makes them last longer on the shelf. A few years ago, you could spot them as an ingredient in many snack and packaged foods, such as margarine, cookies, pizza and chips. (There are also natural trans fats in meats and dairy but only in small amounts and these are not linked to heart health risks.)
Back in 2002, a report found a direct link between trans fat increasing risk of clogged arteries. Manufacturers had already begun phasing out trans fats, mostly replacing them with palm oil. Now, the FDA is mandating all food manufacturers cut partially hydrogenated oils (PHOs), the primary dietary source of artificial trans fat over the next three years.
That’s good news for heart health.

Every time you eat chocolate covered berries or drink a cup of tea, you are getting a dose of flavonoids! Flavonoids are compounds found in plant foods that are well studied for their role in preventing cancers, as well as other chronic diseases.
A new study on flavonoids is highlighted in Cancer Research Update. This study of Australian women looked at the role of flavonoids in preventing death from all causes, including cancer and heart disease specifically. Researchers found that women with the highest intake of flavonoids experienced 62% fewer deaths during the course of the 5 year study compared to those who consumed the least, with similar lower risk from cancer and hear disease.
Flavonoids are generally divided into 6 groups. Foods provide different flavonoids and so may have different health benefits.

The women in this study consumed most (about 80%) of their flavonoids from black tea, which contains flavanols. The women were not, however, eating many foods like Continue reading
