you didn't say what your cholesterol nor your LDL is. Why would you just focus on one number. Its a ratio that is important. Also, the cholesterol numbers are becoming less important in light of other newer and better tests as markers for heart and vascular disease. LPa and APOE and many other lipid panels are being used to complement old cholesterol tests.
To answer your question. I couldn't get my numbers to move for 10 years. Then I had a Ukranian refugee come live with me and I dropped my cholesterol in 2 months from 240 to 195. When she left it went back to 240. So I repeated my diet of salmon, sardines, cod, tilapia, and more fish! It went down again! So I eat more fish! I do all the other good stuff. But it was the fish.
