The use of e-cigarettes, also known as vaping, is gaining in popularity, especially among young adults. I wouldn’t recommend it because the research is incomplete; here’s the latest study. Researchers recruited subjects for three groups: 15 non-smokers, 14 e-cigarette users, and 15 cigarette smokers. The researchers had the subjects spit into sterile containers. Then they […]
Today is the day adults and children will be walking around in a sugar haze: candy at work, candy at parties, trick or treating and eating the haul. Paula and I have the candy-corn-and-peanuts mix out for Halloween season. I happened to see the comic Family Circus on Sunday; it was one of those where […]
Let’s take a look at both types of herd immunity with the goal of deciding which is better in 2017 when it comes to the flu vaccination. Natural Herd Immunity The benefit of natural herd immunity is the innate ability of the immune system to protect against other forms of the same virus. No question […]
Herd immunity is a way to protect a population against the transmission of an infectious disease from one person to another by increasing the number of people who are immune to the disease. This results in lower transmission of the disease and thus protects more people or “the herd”; herd immunity is the only way […]
Based on the response to my email about the flu vaccination, people raised a few questions and I had one of my own. The first question is about viral shedding. Your first thought is probably “What’s that?” Viral shedding is the period of time when you’re infected and can transmit the flu virus to someone […]
The numbers are in and the U.S. is fatter than ever: 39.6% of all adults over 20 years old are obese based on the Body Mass Index. That’s a rise of close to 2% since 2015, the last time the statistics were released. This isn’t affecting only adults; children 2–19 are also fatter than ever […]
Every year I get asked the same question: Should I get a flu shot? Most of the time, I tell people that it’s really up to their health. Do they have a compromised immune system? Are they older? Are they pregnant? Do they have small children? Most people decide that they probably won’t. I would […]
This week it’s time to update prior memos given. The first is a case study on tattoos. It seems people, especially young people, are wearing a lot more ink then they used to. I’ve written about the relationship between tattoos and cancer, but didn’t find enough data to make a recommendation. This memo is about […]
The Memos this week have examined a potential problem with the nutrient content of the plants we eat due to increasing CO2 levels. What does the research show? Part of the problem that Dr. Loladze had was that no one was doing much research on the issue of CO2 and nutrient content. That’s going to […]
Why do you eat broccoli? Why do you eat blueberries? How about sweet potatoes? While you might simply like them, an important reason we eat them in modern countries is for the nutrients they have, such as vitamin C, beta-carotene, and of course those phytonutrients. They’re a source of calories, for sure, but also minerals. […]
