Practice Makes Perfect

Have you ever looked at new health habits as a series of tasks you need to perfect? There are many different habits that are part of a healthy lifestyle such as eating more vegetables, exercising five days a week, taking your supplements regularly, and dozens more. Losing weight is not just eating fewer calories; it’s […]

Eating the Elephant

I’m sure you’ve heard the question, “How do you eat an elephant?” The answer: “One bite at a time!” Paula and I took off last week to try to organize a couple areas of our house. I thought we could get two or three different tasks done. I was wrong; we’re still finishing the very […]

The Magic of Chicory

Because this is my birthday week, I thought I would indulge myself and talk about some personal research I recently did. Today it’s all about chicory—it’s everywhere. The little purple flowers can be found alongside just about every road in Michigan. I’m pretty sure it’s probably that way across the U.S. where the climate is […]

Research Update on Probiotics and Adult Allergies

Researchers recruited a total of 95 adults, ages 19 to 65, with allergic rhinitis for a double blind, randomized, placebo-controlled clinical trial; all the subjects were from two hospitals in South Korea. They were not allowed to take their usual medication to treat seasonal allergies. In the experimental group, 47 subjects received the probiotics, and […]

Research Update on Probiotics for Infants

Let’s begin this week’s research review with a study on the potential long-term benefits of probiotic use in infants. Researchers in Slovenia collected data on 316 healthy-weight newborns whose parents had test-confirmed allergies. The families were divided into two groups: 115 infants were placed into a probiotic group and received probiotics every day between the […]

COVID-19: What We Don’t Know

I’m sure you’ve heard the expression “What we don’t know could kill us” and that’s truer today than at any other time. While we may argue about masks and social distancing, there’s just still too much we don’t know about the novel coronavirus. The critical factor is that because of what we don’t know, we […]

COVID-19 and Obesity

Obesity may be a contributing factor to the severity of symptoms for those who get COVID-19. The best explanation I’ve found why that may be true is in a paper in Nature Reviews Endocrinology published in April. There are several reasons in addition to the cardiovascular and endocrinological co-morbidities associated with obesity. Just a reminder, […]

COVID-19 and Blood Type

This week we’ll examine reports about comorbidities and other factors associated with the severity of the COVID-19 virus. We’ll begin with a question from a long-time reader and family member who shares DNA with Paula: her brother, Steve. Both have blood type A, which has been in the news as a factor in the severity […]

The Bottom Line on Masks

To satisfy my own curiosity, I wanted to do a run/walk to see how wearing a mask might impact my performance. This is tricky for someone with a scientific background; trying to duplicate everything with the exception of the one variable, the mask, is difficult when you’re outdoors. But the weather has been pretty stable: […]

Facts About Masks: Which Material?

If one considers the elemental purpose of a mask, it’s to provide a barrier to reduce the spread of exhaled, potentially virus-containing, droplets. Many opinions on social media cover the size of the viruses, droplets, and the fabric density of masks. I’m not going to do that because it’s the wrong argument. Instead, I’m going […]
