Walking for Exercise Again

How did you do with the Summer Kickoff Challenge? Let’s start with exercise. Did you get at least a 15-minute walk or some other activity done—especially if you’ve been sedentary? As I said last week, this was my first attempt at walking with a purpose since my knee replacement surgery. Of course I’ve been walking […]

Summer Kickoff Challenge

This weekend kicks off the summer holiday season: cook-outs, concerts, backyard cornhole tournaments, the beach. And of course, the food: barbeque, hot dogs and hamburgers, potato salad, ice cream sundaes and pies—more foods than I can name. Here’s my challenge to you: how about making a couple of small changes? First, get a little exercise […]

Distress Is Normal!

We’ve experienced ever-present stress over the past three years, from pandemics to politics to prices of just about everything. It hasn’t slowed down, and that can take its toll—if you let it. Am I saying that stress is normal? I already said that in the last Memo. The objective is to train the body to […]

Living in Anxious Times

A psychologist I’ve interviewed on my local radio show on WGVU-FM, the Grand Rapids NPR affiliate, called me recently to talk about a wave of anxiety that seems to be impacting people: increased visits to doctors and ERs for chest pain, headaches, high blood pressure, and many more symptoms that don’t have a physiological explanation. […]

My Nutrition Questions for This Next Year

Is 100 years a long time? How about 10,000 years or a million? The answer: it depends on the reference point. In human terms, 100 years is a long time, but in terms of changes within a specific type of food or in terms of the microbiome, maybe not. In the next year, there are […]

I’m Alive: V2.53

When I opened my eyes this morning, I knew I had another year to do what I was created to do: teach people how to be healthy and fit. For those of you who are new readers, here’s the story: when I wake on May 10th every year, my superstitious belief is that I have […]

Knowing Your Health Patterns

The reason it’s important to track health variables is to find any patterns in the results. Remember the study on hs-CRP and cancer? Paula immediately looked up her CRP levels and found two things. First, it had gone down consistently over several years. Second, she hadn’t had it tested every year, but she will from […]

Track Your Health Issue

Over the past few months, I’ve written about my blood pressure increasing from being sedentary for five weeks after my knee replacement. I’ve also written about hs-CRP in the study on inflammation and cancer. In addition, I’ve gotten questions about the impact of foods on the digestive system and the variation in blood sugar readings […]

Causes and Risk Factors

Rather than making this a statistics Memo, I’m going to use a couple of examples that illustrate the problems with establishing what prevents or causes disease. Back in the late 1940s to early 1950s, there was a significant increase in cardiovascular disease. Trying to establish a single cause was complicated because there were so many […]

What Is Science?

Along with all the disagreements and conflicting info about covid-19, there has been some confusion about science. Many people seemed to think anything science discovered about covid was complete and final, but that’s not how science works. Science is a constantly changing body of knowledge, or as the Science Council puts it: Science is the […]
