Between bird flu, Rhode Island school closures, conjoined children, the new WHO director, an ethical debate about a disabled daughter, and the ruckus over human-animal DNA splicing, it’s been quite a controversial and bizarre week in the world of science and health.
Frankly, I’ll leave these stories to Google and all the pundits chomping at the 5 o’clock Friday bit. If you’re looking for a little bit of a breather from all this, the Bees have gone hunting for the latest study findings in the field of health, and here’s the best of the catch:
1 – My favorite kind of study: one that’s randomized, placebo-controlled, and long-term (in this case, nearly 7 years!). The findings reveal that supplementing with zinc helps fight aging and age-related diseases, macular degeneration, and oxidation. It’s one of the better-designed studies I’ve seen on zinc. Although, quick note – long-term supplementation with zinc needs to be kept at a fairly low dosage and quality source such as found here . Here is the American Journal of Ophthalmology Clickativity  for those who want the nitty-gritty.
2 – A researcher named Bruce. Now here’s a guy I like. He writes a terrific essay on the need for particular nutrients to mitigate certain effects of aging, cancer risk, and cellular function, and is upfront about his conflict of interest (he’s part of a scientific advisory board involved in the licensing of a supplement that supports mitochondria). Nevertheless, he doesn’t profit, his findings are spot-on, and I appreciate the academic honesty. That’s more than can be said for a lot of conflicts of interest in the medical industry that get hushed.
We’ll be getting into ATP, stress, oxidation and mitochondria in the future to help you understand why our bodies age and weaken the way they do, and what can be done about it (first tip: take a potent multivitamin with antioxidants, and lay off the sugar). But Bruce’s summary  is worth perusing for a quick minute. The more you can do to stop oxidation at the cellular level, the better your health will be in myriad ways: wrinkling and aging, energy, immunity, cognition, disease prevention, liver function, nervous system function, cardiovascular health, and so on. There is a common component to many diseases, illnesses and dysfunctions of the body – it’s cell damage.
3 – Exercise improves life in your golden years. A study from the Journal of Gerontology highlights the critical need for folks over 60 to continue building their strength through exercise. Aging is essentially a process of tissue wasting away – hair, organs, vital fats, muscle and bone tissue, and even brain tissue. Exercise, particularly strength training, offsets this process to the extent that is possible. Living long is great – but I’m interested in living well, too. I’m sure you are as well. Exercise later in life is also critical for maintaining confidence, emotional happiness, and a sense of security – all important things for everybody but especially seniors. Medline Plus, a public service resource, summarizes the study  nicely and offers some fitness tips. It also stresses the importance of a structured workout regimen: we humans do thrive on just a little bit of routine.
