The World Health Organization (WHO) adopted a dose-response function for PM2.5 that lumps outdoor ambient air quality, second-hand (passive) smoking, and indoor household air pollution. It has been used in 80 published studies of the “Global Burden of Health” (GBD). Here I take a closer look and incorporate some additional risk estimates.

The 2021 annual conference of U.S. Mayors adopted a resolution to create community “Blue Zones,” as part of the Well-Being Initiative to Combat Disease and Comorbidities. The Blue Zones program is derived from the work of Dan Buettner, a National Geographic Fellow, who identifies regions around the world where people purportedly live extraordinarily long and happy lives.

Perhaps. A new study in Science suggests a very high prevalence of the Epstein-Barr virus in patients with Multiple Sclerosis (MS). This strong evidence may aid those suffering from MS and give us all a better sense of how endemic infections may have long-term consequences that we are slow to recognize because of the long delay between infection and symptoms.

Ah, the influencer. It’s a new job category for someone who can move markets – at least for goods – by sharing their love of them. This used to be solely the domain of celebrities, but social media has significantly changed that. So when it comes to subjects related to nutrition, the question is: are they using their influence to help or hurt?

Way too many people have experienced the discomfort of food-borne illness: nausea, vomiting, diarrhea, abdominal cramps, and fever. These illnesses are usually mild, but occasionally they can lead to hospitalization, even death. It may surprise you to know that fresh fruits or vegetables can be the source of these illnesses.

Even as the Secretary of Labor (who oversees OSHA) had his wings clipped by the Supreme Court regarding mandatory employee vaccination, the Secretary of Health and Human Services (HHS) was given leave to fly, or rather to mandate vaccination of all staff of programs servicing Medicare and Medicaid enrollees. The number expected to be affected: some 10 million people.

The anti-biotech group GM Watch recently touted the results of a new study as evidence that the EPA has underestimated the risk posed by the weedkiller glyphosate. It's an illustration of what goes wrong when you force data to conform to a predetermined conclusion.

Could anything be more terrifying than your child being seriously ill? Children have been the last group to begin to receive vaccinations. We rightly suggest they congregate daily in schools. How at risk are they in the face of the rising cases of Omicron?

The New York Times recently published an excellent story illustrating what causes vaccine hesitancy and how to effectively combat it. Is the media finally learning that forcing shots on people doesn't work?

Reconsidering zoos, the most famous of monkeys, the symbolism of masks and a goldfish drives their aquarium.
