Cut Protein, Lower Cancer Risk?

Researchers from Washington University (St. Louis) found people with low protein intake had lower levels of hormones linked to cancer risk. The study included three groups: distance runners, vegetarians and "sedentary adults who ate a typical American diet," reported Scientific American. Surprise, surprise, the vegetarians came out ahead in this study.

While the runners also had low levels of hormones lined to cancer, the vegetarians had a lower level of a particularly risky hormone, IGF-1, which encourages cell growth and division. According to the SciAm report, "high IGF-1 levels in the blood have been linked to breast, prostate and colon cancers."

Before you put down the pork chops and pick up some kale, understand the Washington University study was a very, very small. It only included 63 people. One researcher told SciAm that the results are just a "first step" towards a better understanding of the relationship between protein and cancer.

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
