The association between high density lipoprotein (HDL) cholesterol, triglyceride levels and breast cancer risk was investigated in 5,207 Danish women, aged 30 - 80 over a 26 year period.
The study found:
(a) Higher triglyceride levels were associated with higher breast cancer incidence.
(b) Women who had the highest HDL cholesterol had a 70% reduction in breast cancer risk.
High Triglyceride levels are caused by low fat, high carbohydrate diets. See here.
The best way to increase your HDL cholesterol levels is to consume a diet rich in saturated fat. See here, here , here, here, and here.
