Self-study
Although high cholesterol levels have been associated with the development of heart disease, many people with high cholesterol never develop heart disease, while many without high cholesterol do. █████████ █████ ███████ ██████████████ ██ ███ █████ ████████ ██████████████ ████ █████ ██ ███ █████ ██ ████ ██████ █████ █████ ███████ ███ ███ ████████████ ██ █████ ███████ ███████ ███████ ████ ██████ ███████████ ██████ ████ ██ ██████ ██ ██████████████ ███████ ██████ █████ ██ ██ ██████ ███ ██████ ██ ████ ███████ ███████ ███ ███ ████ ██ ██████████ █████ ████████
Summarize Argument
The author concludes that there is no reason for anyone to make dietary changes in order to prevent heart disease. Why? Because one potential cause of heart disease, lipoprotein(a), isn’t affected by dietary changes that do lower cholesterol. And high cholesterol is correlated with heart disease.
Identify and Describe Flaw
The author concludes that dietary changes won’t impact heart disease risk for anyone, but his only support is that they don’t lower lipoprotein(a) levels. What if there was another causal pathway whereby dietary changes could mitigate heart disease risk?
In fact, the author already gave us a good candidate for this: cholesterol, which has been associated with heart disease and which is affected by dietary changes.
