 If our enterocyte trash recovery bins are half filled with phytosterols, might vitamins get crowded out too? We didn't know until last year. But the answer is no, even with a whopping 9 gram dose. Vitamin absorption was unaffected. Plant standals dose-dependently decreased bad cholesterol concentrations, but not antioxidant concentrations in our blood. Now 9 grams is like 10 times what we would expect from even a healthy diet. There's a plateau effect at that 9 grams a day, you're way out here at the end. But as you can see, the cholesterol lowering curve starts to flatten out at about 2. So we can pretty much maximize cholesterol blocking at around 2 grams, or 2,000 milligrams. The standard American diet has been measured as low as 78 milligrams a day. Here's like a model American Heart Association diet, and this is how high folks get eating a plant-based diet. Higher than any other diet pattern reported, that could get you a good 5% cholesterol reduction. But there's definitely room to bump that up further, if necessary. Those who have improved their diets so much they're no longer eating any cholesterol, and should be acing their cholesterol tests. But in rare cases, your body might not be able to get rid of enough endogenous production, and so doubling phytosterol intake could easily double LDL reduction down to 10%, which could double heart disease risk reduction. In terms of whole food sources to maximize cholesterol reduction, seeds provide the most, especially sesame, and then nuts, especially pistachio, and then legumes like peanuts.
