Study this: Cognition, chocolate milk, kids & caffeine

More reasons to stay active from the world of science.

Pump up … your brain. One of my favorite types of studies is the one that shows a link between an active lifestyle and an active brain. The latest comes from the Centre for Hip Health and Mobility at Vancouver Coastal Health and the University of British Columbia, where a follow-up of women 65-75 who participated in a once-a-week strength-training program showed the cognitive improvements registered during the program continued a year later. Specifically, the cognitive benefits in question are the kinds necessary for independent living. Also, the group wound up seeking health care services less often and fell less than the control group. read more

Aha! Proof that the BMI is flawed

It offers quick tips and suggestions for being more physically active and eating better. The site is divided into two components: read more

Assorted news from the research world to get your week kick started:

Green exercise? Really pressed for time? Is carving out 60 minutes a day to work out, as recommended by the National Institutes of Health,  beyond the pale of your schedule? Even 30 minutes broken into bite-size 10-minute segments isn’t doable? According to a study in the current issue of the American Chemical Society’s “Environmental Science & Technology” journal, just five minutes of “green” exercise a day can improve your health — your mental health, at least. Study authors Jules Pretty and Jo Barton say 10 studies involving 1,252 people in the United Kingdom found that just five minutes of gardening, hiking or other pursuits in a green setting decreases your risk of mental illness and improves your sense of well-being.
