The Latest Superfood: Eating Nuts May Save Your Life

In a study released yesterday in the prestigious New England Journal of Medicine, researchers from the Harvard School of Medicine concluded that eating as few as one ounce of nuts each day can reduce the likelihood of dying from heart disease by as much as 25%, cancer by 10% and 20% from diabetes and lung disease.

The study showed that all types of nuts were able to bring about these effects: walnuts, almonds, cashews and even peanuts. The researchers also concluded that the desired effects could be achieved regardless of whether the study participants exercised or were overweight.

The Harvard study actually confirmed a 10 year old study by the US Food and Drug Administration.

According to the researchers, the beneficial effects of eating nuts is derived from the substantial amounts of folate, potassium, fiber, good monounsaturated fats and antioxidants.

Given these results, it would seem that nuts are the latest superfood.

Weight Watchers Endorses High Intensity Interval Training for Weight Loss

As those who read this blog know, I am a strong advocate for Hight Intensity Interval Training or HIIT. Weight Watchers, of course, is the largest and arguably most successful weight loss plan. I am pleased to report that Weight Watchers has acknowledged the benefits of HIIT as an important part of a weight loss plan.

In its September/October 2013 issue of its Weight Watchers Magazine,  Weight Watchers discusses a plan for HIIT, referring to it as the "hottest" approach to walking.  Referring to a study published in the Journal of Physiology, it says that three thirty minute sessions of HIIT are as effective as 5 sixty minute sessions of moderate activity.  The article states that not only can HIIT  supercharge your weight loss program, it can reduce the risk of diabetes and heart problems, at the same time increasing stamina.  

The article suggests three plans, one for the rookie walker, another for the regular walker and a third for the pro.  For the rookie, it suggests 12 repetitions of alternating 30 second push activity followed by 2 minutes of a recovery walk. For the regular, it involves 15 periods of 1 minute of push followed by 1 minute of recovery. and the pro, 20 periods of 1 minute of push followed by only 30 seconds of recovery.

Finally, the article points out three considerations while walking during the push period: 1. take small steps; 2 focus on stepping first on your heel; and 3. pump your arms as though you were running.

Coffree: A Life Saver

Several weeks ago, I wrote about the beneficial effects of coffee "Coffee: Just What the Doctor Ordered", April 28, 2012.. Recently, The New England Journal of Medicine, May 17, 2012,  published an article about a study that showed that coffee drinkers (particularly those who consumed three or more cups a day) had a 10% less chance of dying from heart problems, stroke, diabetes and other causes The study was  conducted by researchers from the National Cancer Institute and the AARP. The researchers followed some 400,000 men and women over a 12 year period. .The study involved those who drank coffee with and without caffeine, so it does not appear that caffeine is the operative ingredient that may be beneficial.

So, have another cup of java and drink up!
