Research on Nature and Health

/in /by

I’m back on the deck to write today’s message about the benefits of spending time with nature (1). Researchers tested over 1,500 subjects who live in urban settings; they wanted to quantify visits to parks in cities with physical measures such as depression, blood pressure, social interactions, and physical activity (2). If you’re a long-time reader, you know I prefer studies with solid measurements such as body weight or cholesterol levels. Surveys and questionnaires are subject to how a person feels at any given moment, but these researchers used the best instruments available.

They found . . .

Blood Pressure: Lifestyle First

/in /by

Today I’m going to share a caution from one of the lead authors in the Mayo Clinic arm of the study and tell you what I think is the biggest mistake the researchers made in announcing the preliminary results of the SPRINT Study.

The Mayo Clinic posted a video from Dr. William Haley, a lead researcher in the SPRINT Study; remember there were 102 different clinical sites that provided data for this study. What he said was significant. Here’s my interpretation: The results of a large study such . . .

Blood Pressure: More Drugs

/in /by

Continuing our look at the SPRINT Study from Tuesday, the study showed a significant reduction in mortality from cardiovascular events such as heart attacks and strokes in subjects older than 50. I can’t argue that those are important results. The question is how did they do it? Here’s how: The group of subjects whose target systolic blood pressure (SBP) was less than 140 were treated with an average of two antihypertensive medications. What did they do with the group whose target SPB was less than . . .

Blood Pressure: A Moving Target

/in /by

In a press release this past weekend, the National Institute of Health released preliminary results of the SPRINT Study (Systolic Blood Pressure Intervention Trial) sponsored by the National Heart, Lung, and Blood Institute. It reported that lowering the target systolic blood pressure (SBP) from 140 mm Hg to 120 mm Hg in people over 50 years old significantly reduced the death rate and cardiovascular events such as heart attacks and strokes.

The subjects were recruited from 102 clinical centers throughout the U.S. (1). The conditions for inclusion in the trial were that men and women must be 50 or . . .

Drinking Your Phytonutrients: The Bottom Line

To finish this series, I’ll briefly cover two recent research studies on coffee and tea, and then give you the bottom line and a recipe.
 
Research
Green Tea and Neuronal Mitochondria
The mitochondria are the powerhouses of the cells, and that includes brain cells. When they operate at peak activity, they provide our brains with the energy for learning and memory. The downside is that they produce many free radicals in the process, and if we don’t have antioxidants to quench those free radicals, it can cause a decline in mental function. Researchers have recently . . .

Keeping Track of Life’s Simple 7

/in /by

To complete American Heart Month, here’s an easy way to track your heart health called Life’s Simple 7 (LS7), developed by the American Heart Association. LS7 has been around since 2010 but it escaped my attention until recently. For those of you who like to track your progress to see how you’re doing, this is a great tool; you may remember I mentioned it last month, but I think you need the details to really understand how LS7 can work for you.

There are seven different categories of variables to track, hence the name Life’s Simple . . .
