Prebiotic Foods List with PDF

Probiotics! Prebiotics! The internet is buzzing with these words. Wondering what the hype is all about? Let us first understand the basic difference between probiotic and prebiotic foods and how they can be beneficial for our health. Prebiotics are a “type of dietary fibre” that supports your body’s friendly bacteria while probiotics are the “live bacteria” found in various food sources. For general health and well-being, maintaining a healthy gut is crucial. Prebiotics are a type of fibre that feed the good bacteria in the gut, supporting immune and digestive health.

Prebiotics promote the production of nutrients like short-chain fatty acids or inulin in your colon cells by your gut bacteria, leading to a healthier gastrointestinal tract. [1]. Your bloodstream can absorb these fatty acids, which in turn enhance your metabolic health [2].

How does prebiotic food help probiotic bacteria

How does prebiotic food help probiotic bacteria?

Prebiotics give probiotics the environment and food they need to develop and flourish. Prebiotics are consumed and pass through the upper digestive tract undigested before entering the large intestine where they are fermented by Lactobacillus and Bifidobacterium, two types of good bacteria. Short-chain fatty acids, such as butyrate, propionate, and acetate, are created during this fermentation process. These fatty acids provide probiotics with energy and support the maintenance of a healthy gut environment.

What is the best way to increase prebiotic intake?

Prebiotic supplements, prebiotic-rich foods, and functional foods that have been fortified with prebiotics are some of the ways to increase prebiotic intake. Here are some pointers for raising prebiotic consumption, along with a reference to a review article that details these strategies:

  • Eat foods naturally high in prebiotics, such as oats, garlic, onions, asparagus, bananas, and bananas, to help increase your intake of prebiotics.
  • Prebiotic supplements can be found in pill, powder, and liquid form; examples include inulin and fructooligosaccharides (FOS). You can take these supplements by themselves or in conjunction with probiotics.
  • Prebiotics are increasingly being added to functional foods like yogurt, cereal, and snack bars to help support digestive health.

 7 Best Prebiotic Foods for a Healthy Gut 

  • Garlic 


 Garlic has been linked to potential health advantages like lowering the risk of cardiovascular disease and particular types of cancer because it also contains antioxidants. It is also an excellent source of inulin, a prebiotic fibre that has been shown to encourage the growth of beneficial bacteria in the gut. A 1-ounce (28-gram) serving of garlic contains 4 grams of carbohydrates, including 0.2 grams of fibre and 0.5 grams of sugar.


  • Onion 


Onions are a good source of prebiotic fiber in the form of fructooligosaccharides (FOS)Onions are also rich in vitamin C and other antioxidants, which may help prevent chronic diseases like cancer and heart disease. Inulin, which promotes the growth of good bacteria in the gut, is found in abundance in raw onions. A 3.5-ounce (100-gram) serving of onions contains 9 grams of carbohydrates, including 1.7 grams of fiber and 4.2 grams of sugar.


  • Chicory Root

Chicory Root

Chicory root is a great prebiotic food because it is one of the richest sources of inulin. Since ancient times, it has been used as a home remedy for a number of illnesses, including liver and digestive issues. Studies suggest that chicory root may have health advantages like lowering inflammation and enhancing blood sugar regulation. A 1-ounce (28-gram) serving of dried chicory root contains 24 grams of carbohydrates, including 14 grams of fibre and 0.4 grams of sugar.


  • Asparagus


Inulin, which encourages the growth of good bacteria in the gut, is present in raw asparagus in significant amounts. Additionally, asparagus contains significant amounts of antioxidants, vitamins, and minerals that may help prevent chronic illnesses like cancer and heart disease. According to certain studies, asparagus may be anti-inflammatory and antimicrobial, and it may also help with better digestive health and blood sugar control.


  • Dandelion Greens 

Dandelion Greens 

Dandelion greens when eaten raw are a good source of inulin, which promotes the development of good bacteria in the gut. Raw dandelion greens are also rich in antioxidants and have been used for centuries as a natural treatment for a variety of illnesses, such as liver and digestive issues. Scientific data shows that greens could potentially improve blood sugar regulation and reduce inflammation.


  • Jerusalem Artichoke

Jerusalem Artichoke

Inulin, which is abundant in raw Jerusalem artichokes, helps the growth of good bacteria in the digestive tract. In addition, it is a good source of vitamins and minerals like thiamine, potassium, and iron. Scientific evidence suggests that  Jerusalem artichokes may have health advantages like lowering inflammation and enhancing blood sugar regulation. A 3.5-ounce (100-gram) serving of Jerusalem artichoke contains 17 grams of carbohydrates, including 1.6 grams of fibre and 9 grams of sugar.


  • Leek 


Raw leeks are a good source of inulin. Leeks are also rich in vitamin K, which is crucial for bone health, and other antioxidants that may help prevent chronic illnesses like cancer and heart disease, leeks are a good source of these nutrients. Leeks may have anti-inflammatory and antimicrobial properties, as well as the potential to lower cholesterol and blood pressure, according to some studies. Leeks are a good source of prebiotic fibre in the form of fructooligosaccharides (FOS). A half-cup (52 grams) serving of chopped raw leeks contains 0.9 grams of fibre, including 0.4 grams of FOS, and 2.1 grams of sugar.


Fruits are rich in natural sugars and fibre making them a good source of prebiotics. You can easily incorporate prebiotic-rich fruits into your diet for better health. Read on to find out more fruits that are good prebiotics.
