Score another one for physical activity

            Most people are aware that regular physical activity – a euphemism for the E-word – goes a long way to prevent heart disease, obesity and type 2 diabetes as well as a host of other bodily ills but fewer are aware that the mind can benefit, and to a very significant degree.

          A report from the University of South Australia has revealed some surprising facts, including: “Physical activity was found to be 1.5 times more effective than counseling or the leading medications in managing depression and is being recommended as a mainstay of treatment.” And to think that it  doesn’t cost anything!

          The timing is important in view of the fact that depression, especially among teenagers, has increased dramatically since the onset of the COVID-19 pandemic.

          The benefits accrue to other populations: pregnant and postpartum women, persons with HIV and those with kidney disease.

          A particularly interesting finding is that it needn’t take lots of time. The researchers found that bursts of short and mid-duration proved more beneficial than exercise of longer duration.

          Nor does it matter how you exercise. Anything that gets your body moving and your heart rate up will be of benefit, including yoga, walking, swimming, resistance training (weights and  machines) and Pilates. Biking is also a great exercise but PLEASE – not an electric bike!

Don’t like fish? How about walnuts?

            Most persons who get the omega-3 fats that they need obtain them from fish or fish oil supplements. Fish is the better choice because it tastes better and doesn’t give you “fish burps” and because it is an excellent source of protein.

          If you’re not a fan of fish and don’t like taking those rather large fish oil capsules, walnuts might be a good substitute. They are rich in omega-3 fats, protein, magnesium, vitamins B1 and B6, zinc, and antioxidants.

          And according to a recent study from Spain, they are a great addition to the adolescent diet. Teenagers who ate about one ounce of walnuts at least three times a week showed a reduction in ADHD and a boost in their attention span and cognitive function. The research team also measured their risky-decision-making score using the Roulettes Task (!) but walnuts didn’t seem to help. Darn!
