When I was in grad school, I made my way over to the environmental studies building a couple of times so that I could recruit potential participants. Each time I was there, I noticed something strange. Everyone there was in the “normal” category for body mass index. Moreover, all the participants I screened from that program were ineligible because they were already physically active. It made me wonder, is there something about being an environmentalist, or an environmentally friendly person, that makes one healthier?
As far as I can tell, the answer is YES. I should mention that this article is completely opinion based (and somewhat observational). I’m sure there are overweight enviro-friendly people; I’ve just never met one! So what is it about being green that makes one healthy? My guess is two things; active transportation and local fresh food.
Active transportation means that instead of sitting in a pollution spewing car, enviro-friendly people opt to walk or cycle to work or school. If the distance is too great, they are more likely to take public transit, which also requires a bit of walking (to and from the bus-stop). There are several studies to indicate that those who engage in active transportation are more likely to be in the normal body mass index category. There is also emerging evidence that these individuals are overall healthier.
Eating locally grown food is known to reduce one’s carbon footprint, but it may also mean committing to eating fewer processed foods. Eating produce, breads and meat from local farms means more home cooking and consumption of fewer foods with added sugar and preservatives. Thus by eating local foods, one might be committing to a healthier diet as well as a greener planet.
Surely there are other behaviours that contribute to this “phenomenon”. But as a health and exercise scientist, these two are the most obvious ones to me. What is also obvious from writing this article is that a commitment to a green lifestyle might also be an important step in committing to a HALF!
