A May 2017 study by Queensland University suggests that,

“There is good evidence that three grams or more of oats beta glucan consumption a day can help reduce cholesterol levels.”

The study follows and earlier Queensland University study that demonstrated that the beta glucan fibre in oats “can slow absorption of fats to reduce blood cholesterol.”

The University perfected, “a low-fat blueberry muffin recipe” which contain “three grams of beta glucans - a healthy soluble fibre that occurs naturally in the cell walls of oats and cereals, and meets the food standard guidelines for cholesterol-lowering properties.?”

Researchers said, “The trick was to avoid making the muffin gluggy from all the extra oat bran and beta glucan fibre." And concluded, “Eating a muffin a day is a convenient way for people to improve their heart health."
