Nourishing Your Gut: Global Prebiotics Week 2023

In this blog we explore the importance of prebiotics, their various types, and the numerous food sources that contain them. Let’s take a closer look at the world of prebiotics, their role in feeding good bacteria, and the profound impact they have on our health.

Understanding Prebiotics

Prebiotics are a class of dietary fibers that our bodies cannot digest. Instead, they serve as nourishment for the beneficial bacteria inhabiting our gut, AKA probiotics. By providing this vital sustenance, prebiotics promote the growth and activity of these good bacteria, creating a harmonious environment within our digestive system.

How Prebiotics Work

Prebiotics play a crucial role in promoting gut health through a variety of mechanisms:

  • Selective Feeding: Prebiotics are selectively fermented by beneficial bacteria such as Bifidobacteria and Lactobacilli, which are known for their health-promoting properties. This selective feeding encourages the growth and activity of these good bacteria, helping to crowd out harmful pathogens.
  • Acid Production: As beneficial bacteria break down prebiotics, they produce short-chain fatty acids (SCFAs) such as acetate, butyrate, and propionate. These SCFAs have numerous health benefits, including reducing inflammation, improving gut barrier function, and regulating appetite.
  • Enhanced Nutrient Absorption: A healthy gut microbiome, nourished by prebiotics, can improve the absorption of essential nutrients, including certain vitamins and minerals.
  • Immune Support: A well-balanced gut microbiome, maintained by prebiotics, contributes to a stronger immune system by influencing the development and function of immune cells.

Different Types of Prebiotics

There are several types of prebiotics, each with its unique qualities. Some of the most well-known ones include:

  • Inulin: Found in chicory root, Jerusalem artichoke, and onions, inulin is a widely recognised prebiotic. It helps support the growth of Bifidobacteria in the gut.
  • Fructooligosaccharides (FOS): Present in foods like bananas, garlic, and leeks, FOS serves as a valuable prebiotic that encourages the proliferation of beneficial bacteria.
  • Galactooligosaccharides (GOS): Sources like legumes and human breast milk contain GOS, promoting the growth of Bifidobacteria, which are known for their positive impact on gut health.
  • Resistant Starch: This type of prebiotic is found in foods like green bananas, legumes, and whole grains. It resists digestion in the small intestine and reaches the colon, where it feeds beneficial bacteria.

Food Sources Rich in Prebiotics

Global Prebiotics Week is the perfect time to discover and celebrate the diverse array of foods that provide prebiotics. Here are some excellent dietary sources:

  • Chicory Root: Often used as a coffee substitute, chicory root contains a substantial amount of inulin.
  • Garlic and Onions: These aromatic ingredients are not only flavorful but also excellent sources of prebiotics.
  • Bananas: Unripe bananas are high in resistant starch, making them an ideal choice for boosting gut health.
  • Legumes: Lentils, chickpeas, and beans are rich in prebiotics, particularly resistant starch and GOS.
  • Whole Grains: Oats, barley, and whole wheat contain resistant starch and contribute to a diverse gut microbiome.

Benefits of Prebiotics for Gut Health and Overall Well-being

  • Improved Gut Microbiome: Prebiotics stimulate the growth of beneficial bacteria like Bifidobacteria and Lactobacilli, resulting in a balanced gut microbiome.
  • Enhanced Digestion: A healthier gut can lead to improved digestion and absorption of nutrients from food.
  • Boosted Immune Function: A well-nourished gut can bolster the immune system, helping the body fend off infections and illnesses.
  • Reduced Inflammation: Prebiotics may help reduce inflammation in the gut, potentially lowering the risk of chronic diseases.

Prebiotic-Rich Chickpea and Garlic Hummus


  • 1 can (15 oz) of chickpeas, drained and rinsed
  • 3 cloves of garlic, minced
  • 2 tablespoons tahini (a sesame seed paste)
  • 2 tablespoons extra virgin olive oil
  • 1 lemon, juiced
  • 2 tablespoons water
  • 1 teaspoon ground cumin
  • Salt and pepper to taste
  • Optional toppings: a drizzle of olive oil, paprika, and fresh parsley


  • In a food processor, combine the chickpeas, minced garlic, tahini, extra virgin olive oil, lemon juice, water, ground cumin, salt, and pepper.
  • Blend the ingredients until the mixture becomes smooth and creamy. You may need to scrape down the sides of the food processor with a spatula and blend again to ensure a consistent texture.
  • Taste the hummus and adjust the seasonings as needed. You can add more lemon juice, salt, or cumin to suit your taste.
  • Once you’ve achieved your desired flavor and consistency, transfer the hummus to a serving dish.
  • If desired, drizzle a bit of extra virgin olive oil on top, sprinkle with paprika for color, and garnish with fresh parsley.
  • Serve your prebiotic-rich hummus with whole-grain crackers, raw vegetable sticks, or whole wheat pita bread for a tasty and gut-friendly snack.
