Vitamin D vs. Long COVID

Returning to the vitamin D study, the rest of the headline suggested that taking vitamin D upon getting COVID may reduce symptoms of long-term COVID (LTCOVID), a serious aftereffect of a COVID infection that can impact the nervous and muscular system. Brain fog, chronic fatigue, and pain are some of the common symptoms. The reason […]

Does Vitamin D Beat COVID?

My Monday morning news feed contained at least three referrals to a recent article published in the Journal of Nutrition. The headlines were all about the same: vitamin D supplementation is ineffective in the short term as a treatment for COVID but provides insight into how to reduce the risk of long-term COVID symptoms. I […]

What Changed? 2015 vs. 2025 Dietary Guidelines

If you read any of the commentary about the latest dietary guidelines, you would have thought there were radical changes. “Eat or drink full-fat dairy! Use beef tallow! Ultra-processed food should be eliminated!” If you took the time to read the synopses, there are very few differences between the recommendations. They still use the same […]

The 2015 and 2025 Dietary Guidelines

What were the Dietary Guidelines that were published for 2015? Can you remember any of them? What are the Dietary Guidelines for 2025? Did you read them? Here’s your chance. The 2015 Dietary Guidelines were released 10 years ago; the 2025 version about a month ago. Research was reviewed. Meetings were held. Comments were given. […]

Clock-Changing Solutions

We’ve become so obsessed with sleep, even our watches can track the amount of quality sleep we get, so we can expect something unusual tonight. We go to bed at our usual time and for most of us in the U.S., we wake up one hour earlier than planned because the clocks have changed. As […]

Warning: Spring Ahead

This coming weekend, the clocks are moved ahead one hour in most states here in the U.S. This seems to impact some people more than others; our bodies are more sensitive to the effects of changing sleep patterns than we think. I first wrote about this 10 years ago, and I wanted to check to […]

Immune Booster 2 and 3

Continuing with our look at how to approach the first tickle of a cold or seasonal allergies, we’ll finish up with the final two parts of our immune boosting supplements. Garlic The second part of our immune boost supplements is garlic; it’s been noted to have beneficial properties for over 5,000 years. Garlic thins the […]

Immune Booster 1: Echinacea

Just like nine years ago when I first wrote this, the cold and flu season is still around. The seasonal allergy season is right around the corner and may have started, depending on where you live. When you feel that first tickle in the back of your throat, that first nasally sensation, that’s when you […]

The Bottom Line on Full-Fat Dairy

If you’re a long-time reader, you know that science by headlines really annoys me because they often distort the findings of the research papers to make them seem more important than they are—gotta get that next click! It doesn’t help that research institutions send out press releases that contribute to the hype of their research […]

Does Whole Milk Reduce Diabetes?

Full-fat foods are back in the headlines in light of the recent proclamations by the USDA. I don’t know about you, but it’s been decades since I drank whole milk or ate whole fat yogurt or cheese. It’s not just about the calories; it just doesn’t seem to taste as good. Have I been missing […]
