On the Road Again

To say that I’ve had a little agony over not running would be an understatement. I certainly don’t want to do anything that’s going to impact the new joint in my knee; on the other hand, my frustration continued to grow over the inability to exercise as hard as I want to exercise. I did […]

Knee Replacement Update

It’s great to be back! I hope your 4th of July holiday was great. Spending some time in Nashville with a few thousand of my closest friends just before the 4th, one of the questions that I was often asked was “How about an update on your knee?” I’ll tell you how I’m doing, but […]

Yes, Intensity Matters

Can you get away with less time exercising and still protect your cardiovascular system? We know from Tuesday’s Memo that more time spent on physical activity will provide more protection. Can we save some time? Or perhaps better stated, can we do something in short bursts of time that can increase the moderate to intense […]

How Hard Should You Exercise?

Exercise is my most favorite thing to talk about—not surprising for an exercise physiologist. There’s no question that diet is important to our health, but if I had to focus on just one habit that people should adopt, it would definitely be exercise first before anything else. I believe we should all eat more vegetables […]

More Taurine, Longer Life

The researchers next step was to supplement the diet of several species with taurine to see if the lifespan of various species would be increased. While they didn’t include humans in the study (we live too long), they did note in other studies that some factors related to aging declined with taurine supplementation. Taurine supplementation […]

Taurine’s Effects on Aging

A recent research paper examined the amino acid taurine and its connection to aging; in fact, the title of the research paper is “Taurine as a Driver of Aging.” It was published in the journal Science in June 2023; it’s open access if you’re interested in reading the article itself. Taurine is a sulfur-containing amino […]

The New Research Isn’t Really About Sucralose

Those of you who actually read the research paper mentioned in the last Memo didn’t have to go past the title to find out that it was not about sucralose—it was about a contaminant called sucralose-6-acetate that may be found in commercially available sucralose used in drinks and baking products. I said the tests were […]

New Research on Sucralose

Everybody seems to be talking about sucralose. In the past week, I’ve gotten more emails about the artificial sweetener sucralose than I ever have before; I’ve also seen more commentaries on sucralose in health news feeds. The problem is that the issue really isn’t the sweetener itself—it’s a contaminant that may be found in the […]

Flavanols: The Real Brain Food

As I suggested in the last memo, the researchers did not prove their hypothesis that there would be an increase in measures of memory in all participants of the clinical trial. While disappointing, the secondary hypothesis might have been even more important because it was statistically significant. They found that those with the lowest intake […]

What’s Brain Food?

If I ask what you think a good brain food would be, what would you answer? I think for most people, it would probably be fish, especially cold-water fish such as tuna and salmon. I don’t think we can discount how important omega-3 fatty acids are to the function of our bodies, especially our nervous […]
