Red onions are big prebiotics and are particularly rich in the prebiotic inulin and fructooligosaccharides. Raw onions contain 8.6% prebiotic content, which is a lot for vegetables. They have tons of health benefits such as better blood sugar control, lower cholesterol, and lowering blood pressure. These onions are so easy to make and loaded with probiotics too!
