These foods I mentioned are part of the "Portfolio Diet". It is a plant-based diet designed to lower cholesterol by as much as 30%. It was developed by a number of researchers at St.Michael's hospital in Toronto. Google Dr. David Jenkins who is a Professor of Nutritional Sciences at the University of Toronto and head of a clinic at St. Michael's Hospital. He developed the concept of the glycemic index.
The diet works. I did follow it for about 2 years with the exclusion of barley and whole wheat grains as I am a celiac. Dr. Jenkins practices what he preaches: he is a vegan. I still make a delicious baked tofu dish on a regular basis.
