Paula gave me an article to read from The Atlantic written last summer, in which author David Merritt Johns tackled the issue of outlandish results in nutrition-science studies. In this case, the issue was research demonstrating that eating ice cream regularly reduced the risk of developing type 2 diabetes and cardiovascular disease. He interviewed the […]
While I’m spending the day making sure today’s primary election in Michigan goes smoothly in my precinct, here are some of my thoughts and questions about fish oil and omega-3 fatty acids. That’s the way I see it. It’s also why I think eating a good diet will prove to be beneficial when taking fish […]
Let’s put the fish oil study from Tuesday in perspective. The most important thing is that observational studies such as these cannot demonstrate cause and effect. That’s not just a way to weasel out of making definitive statements; it’s because while fish oil supplements are associated in some way with atrial fibrillation in people who […]
Researchers recently published an observational study on over 415,000 subjects in the UK Biobank database who took a fish oil supplement. During a follow-up period of almost 12 years, they statistically demonstrated a 13% increased hazard ratio (a measure over time of how often a particular event happens in one group compared to another group) […]
If you’re concerned about taking your multivitamin, I think you can lower the concern. Is it still possible that there may be individuals who may have a unique set of genes and covariates that may increase the risk? Sure, it’s possible, but this study brought us no closer to finding out if that’s true. Here’s […]
Close to a month ago, the health headlines were full of warnings about multivitamins. A long-time researcher even did a video to explain the study. This headline was based on a study that demonstrated an increase in Hazard Ratio if a person took a multivitamin every day, compared to occasionally or never. On the face […]
Remember where we began: frustrated with the conflicting studies on nutrition and their impact on our health. The researchers used specification curve analysis to illustrate several issues. The most important point is that there are many ways to analyze large datasets in nutritional epidemiology. Reviewing 15 studies in 24 papers, they found that the number […]
Did you look up quadrillion? It’s a 1 with a whole lot of 0s—15 to be exact. When I finished Saturday’s Memo, the researchers had chosen an area of nutritional epidemiology to focus on: the analytics used to analyze the data. They began with the premise that there are many ways to analyze any data […]
The health headline shouts: “Fish oil increases your risk of heart disease.” The next week, “Fish oil beneficial for reducing risk of Alzheimer’s disease.” It makes one wonder what is going on in research. I’ve felt that way for a long time, and I know you have as well. I think I’ve found part of […]
Did you keep track of the fruits and veggies you ate over the holiday weekend (or July 4–7 for those of you outside the U.S.)? Remember to email me your results. Some people didn’t need reminding—I have already gotten replies. I didn’t do as well as I would have liked. Here are my lists: I […]
