Quote:

Circulating lipoproteins influence cardiovascular disease risk, and LDL is a particularly important one. Things that increase the number of LDL particles, and/or their total cholesterol cargo (called LDL cholesterol) tend to increase cardiovascular disease risk. The evidence supporting this is now extremely strong (1, 2).

As it turns out, butter increases LDL cholesterol and particle number more than most other fats (3, 4, 5, 6). While butter also increases “good” HDL cholesterol, recent drug trials have questioned the causal relevance of increasing HDL cholesterol, meaning that it may not actually protect you from an increase in LDL cholesterol (7).
