Kimchi, a Korean fermented side dish commonly made from cabbage, radish or cucumber, is quickly gaining a following for its many health benefits. Kimchi is high in fiber and—because it's fermented—is loaded with good bacteria that help keep your gut healthy. Kimchi contains bioactive compounds that lower cholesterol by blocking cholesterol from being absorbed into the bloodstream. The good bacteria produced during fermentation also help lower cholesterol. Kimchi and sauerkraut are usually pretty high in sodium, so watch your portions if you're watching your salt intake.
And according to some powerful experiments by software engineer-turned-biohacker Dave Feldman, you can actually increase and decrease your cholesterol at will. It all depends on how much fat you eat — and, directly against mainstream dietary knowledge, the correlation is inverted. In other words, eating more fat will actually lower your cholesterol.
