Natural Fiber vs. Added Fiber
In a recent paper, researchers reviewed the literature to see whether there are benefits to eating more plant foods or whether adding insoluble fiber to processed foods would be an adequate substitute. But first, a review. The Recommended Dietary Intake of fiber is 25–35 grams per day; American adults eat only 10–15 grams per day. […]
How Can Vaccinations Reduce Alzheimer’s Disease?
In reading possible explanations for the potential benefits of flu vaccinations for reducing the risk of Alzheimer’s disease (AD), it always comes back to reducing inflammation. Further, it isn’t just the flu vaccine that seems to have that effect. Pneumonia, DTAP booster, shingles, and others have also been studied with similar results: vaccinations seem to […]
Flu Shots and Alzheimer’s Disease
One of the benefits of large cross-sectional studies, especially in the age of electronic medical records, is that medical tests and treatments can be examined while examining diagnoses at the same time. The Veterans Health Administration is one of many medical databases that can identify relationships between health factors and the onset of disease. In […]
Timing for Enzymes, Prebiotics, and Probiotics
My digestive system has undergone changes—it doesn’t work like it used to work. Hence, I’ve been paying closer attention to digestive supplements. My voice had been getting raspy, and I had occasional reflux; I was concerned the two were related. I had an endoscopy and found I was correct. They also found a hiatal hernia. […]
Timing May Be Everything
I’ve recently gotten a few questions on the timing of dietary supplements. That means it’s time for a review. The first category would be multivitamins-multiminerals (MVMM) and other single- or multi-nutrient vitamin-mineral combinations such as calcium plus magnesium and vitamin D. The best time to take them is during or after a meal. The reason […]
Another Theory of Obesity
It’s been a while since someone has proposed a new theory of obesity. I’m still a believer in “a calorie is a calorie” but it’s always good to find out what may be driving us to overeat. The latest addition is the Fructose Survival Hypothesis for Obesity. The diagram above was taken from an article […]
Your BMI and Shrinkage
I received several interesting questions regarding the loss of height and its impact on BMI: should you use your current height or your tallest height? I checked the research and found some interesting ideas, but there’s no direct answer. While it may change slightly over time, your current height should be used to estimate BMI. […]
The Bottom Line on the Blue Zones
The docuseries on Blue Zones demonstrated that it really isn’t complicated to live to 100: find a purpose, a reason to get up every morning, remain physically active, eat reasonably with a focus on plant-based sources for food, and develop a social group that can provide support through the various stages of life. The docuseries […]
Blue Zones: Social Groups
As I said on Saturday, when I began watching the Blue Zones docuseries, I would have wagered that either nutrition or exercise would be the most important factor in living longer. What we eat and how much we move are important, but the key to living well to 100 are the interactions we have with […]
Blue Zones: Eat Reasonably
As I continued to consider the four areas that make up the health habits related to living to 100, I would have thought that nutrition was going to be the key. After much reflection, it’s not. However, it doesn’t mean you should live on a diet of sweets, deep-fried foods, and a lot of ultra-processed […]
