Prebiotics, not to be confused with probiotics, are specific types of fiber found in various plant-based foods. They stimulate the growth of beneficial gut bacteria, which is essential for overall health. A diet rich in prebiotics can help maintain a balanced gut microbiome, contributing to improved digestive function, better absorption of minerals like calcium, enhanced blood glucose regulation, and a robust immune system.

What’s more, prebiotic-rich foods are high in fiber, a nutrient many of us are not getting enough of in our diets. According to Cassandra Boyd, a master’s student at San José State University, “Eating prebiotic-dense foods has been shown by previous research to benefit health. Eating in a way to promote microbiome wellness while consuming more fiber may be more attainable and accessible than you think.”

Boyd and Assistant Professor John Gieng, Ph.D., used existing scientific data to analyze the prebiotic content of 8,690 foods contained in the Food and Nutrient Database for Dietary Studies. The results, presented at NUTRITION 2023 in Boston, found that around 37% of the foods in the database contained prebiotics. Among them, dandelion greens, Jerusalem artichoke, garlic, leeks, and onions had the highest amounts, ranging from 100-240 milligrams of prebiotics per gram of food. Other notable mentions were onion rings, creamed onions, cowpeas, asparagus, and Kellogg’s All-Bran cereal.

“Onions and related foods contain multiple forms of prebiotics, leading to a larger total prebiotic content,” said Boyd. The fact that these foods are commonly consumed means they’re an easy way for us to ramp up our prebiotic intake.

So, if you’re seeking to promote your gut health, adding these prebiotic-rich foods to your diet could be a simple and effective way to do so. Your gut will thank you!
