What weather we’ve had this month! The wettest drought since records began all the way to the glorious week of summer. The important question, of course, is will it be a washout during the Queen’s Diamond Jubilee bank holiday next week?
1. It’s typical that the weather is a bit rubbish around bank holidays, but a lack of vitamin D means much more than rickets. A Danish study adds to a growing body of evidence that the paucity of sunlight in the UK for most of the year not only makes us miserable, but could actually be doing us harm.
2. Another preliminary study from Denmark showed that joggers live longer, with an average of 6 more years of life. The interesting thing about this research is that it appears, the “optimum benefit was realized for those who jogged at a slow-to-average pace between an hour and two and half hours done in two to three sessions over the course of a week.”
3. And now from jogging to just plain moving. Last week I blogged about research showing that sitting is really bad for you. So in the scheme of things: sitting is really bad, standing is good and moving is even better. You would think then that running marathons is much better than sprinting – after all you’re putting in so much more effort for a much longer period of time. As it turns out, that’s another myth, so hurray for us time-strapped people. Time Healthland had an interesting interview this month with New York Times columnist and author Gretchen Reynolds about her new book on how a little exercise brings big benefits.
4. What do you think is the cause of the obesity epidemic: our more sedentary lifestyles, the lack of exercise, genetics, poor diets or overeating? Carson C. Chow is an investigator at the National Institute of Diabetes and Digestive and Kidney Diseases trying to figure out why 1 in 3 Americans are obese. The surprising thing about Dr Chow is that he’s an M.I.T.-trained mathematician and physicist using mathematics to solve the problem. His work has brought up some interesting information such as “the fatter you get, the easier it is to gain weight. An extra 10 calories a day puts more weight onto an obese person than on a thinner one”. Read the complete interview here.
5. As news of a “fat tax” on unhealthy food was being discussed, UK sales of processed breakfast cereals are dwindling with more and more people favouring healthier, more natural alternatives to the sugary brands. Nick Barnard of natural foods company Rude Health says, “I do think, in 20 years’ time, we might look back at the past 100-odd years and say: ‘We took good, natural, healthy, original grains, and turned them into sweet, scientific, industrial concoctions. Why?'” Put that way, it does seem all a bit silly, doesn’t it?
