30 Jul 2018 --- The portfolio diet, a plant-based way of eating previously shown to lower cholesterol levels, also reduces other risk factors for cardiovascular disease including blood pressure, triglycerides and inflammation, University of Toronto researchers have found. In addition to reducing LDL (or “bad”) cholesterol by about 30 percent when combined with a low-saturated fat diet – a level comparable to medications – the researchers found the diet limited other factors for an estimated 13 percent reduction in the overall risk for coronary heart disease, which includes angina and heart attack.
