How a Study Can Show Something to Be True When It’s Completely False — Regression to the Mean

In a previous post, “The Great Unknown: Using the Statistics to Explore the Secret Depths of Unpublished Research,” I discussed one way a study can show something to be true when it’s false, or vice versa. If some nutrient or drug has a “true” biological effect, and we repeat many studies of the phenomenon, we …

Getting Better Sleep — Cool, Dark, And Lots of B6, Carbs, Calories, and Fat

Muscle meats and eggs are very rich in methionine, which increases our need for homocysteine-neutralizing nutrients (vitamins B6, B12, folate, betaine, and …

Genes, LDL-Cholesterol Levels, and the Central Role of LDL Receptor Activity In Heart Disease

Are high concentrations of LDL-cholesterol a major cause of heart disease?  If we are a proponent of the “lipid hypothesis,” we say yes.  If we are a “cholesterol skeptic,” we say no — total cholesterol, LDL-cholesterol, LDL particles, triglycerides, and other blood lipids have little or nothing to do with heart disease. I believe both of these positions …

What Can Familial Hypercholesterolemia Mortality In the 19th Century Teach Us About Genetics?

by Chris Masterjohn Not much, simply because the data are so poor.  However, let’s take a look at some data for the very weakly supported hypothesis that people in the 19th century with familial hypercholesterolemia lived longer than other people and perform a little “thought experiment” to see what it could teach us about genetics if …
