High density lipoprotein (HDL) cholesterol levels were measured in 20 patients with gastric cancer and in 20 age-and gender-matched healthy controls.
The study found that HDL cholesterol levels were 43% higher in healthy people compared to patients with gastric cancer.
Consuming a diet rich in saturated fat is the best way to raise HDL cholesterol levels. See here, here and here.
