COVID-19 and Wildfires: PM2.5 Rears Its Ugly Head, Again

By Fred Lipfert, PhD — Aug 30, 2021
A recent analysis of COVID-19 and the 2020 wildfires in California, Oregon, and Washington estimated increases in COVID cases and mortality of about 20% associated with increased levels of fine particulate matter (PM2.5) based on satellite smoke observations. The study caught my eye for several reasons: PM2.5 is not “smoke,” the COVID-19 increases were not statistically significant, and a much simpler and transparent analysis of their data yielded different results. Here’s what I found.

Environmental Working Group Doesn't Want You to Rub a Peach on Your Face

By Josh Bloom — Aug 27, 2021
What could be more delightful than a summer peach? The taste and scent are unmatched in the world of fruit. But beware. Chemicals are responsible for both the taste and scent and the Environmental Working Group doesn't like some of them. The salaries of those at the EWG are just peachy, but the chemical acumen of the group is the pits.

A long-time critic of 2016 CDC guidelines for prescription of opioids calls for replacement of the CDC writers' team now revising the guidelines. Draft recommendations reviewed July 16th, 2021, double down on errors of science and misdirections which characterized the original. The present team has fundamental professional conflicts of interest and lacks first-hand expert knowledge of pain management practice.

New Lens to View a Nutritional Diet

By Chuck Dinerstein, MD, MBA — Aug 25, 2021
MyPlate, the USDA’s idea of a nutritional diet, is so yesterday. And it’s influenced by industrial forces. But is natural better – and what is "natural" anyway? A new study brings an entirely new viewpoint to what’s nutritional and sustainable. And it’s worth considering, even if it’s taken with a few grains of salt.
