Consumers are digesting the fact that gut health is inextricably linked to well-being. While the notion of “You are what you eat” is hardly new, the collectively deeper dive into the importance of the gastrointestinal tract and how to properly maintain it is evident in the spate of products on the marketplace that tout better digestive health. For some people, it’s about weight loss. For others, maintaining or improving their gut bacteria is a step in preventing disease and building up immunity. Whatever is driving their interest in products that keep the gut healthy and happy, you can deliver on it with offerings that fit their lifestyle and their taste. Read on to learn about the ways in which the human body’s littlest organisms are a big deal.

It’s All Linked

Consumers today are becoming even more aware of the direct connection between the digestive system and human health.

A Few Facts About Our Gut Health:

  • The gut is where you digest and absorb nutrients from food.
  • A healthy gut with healthy bacteria can protect against infections, pathogens and potentially some types of cancers.
  • This area of the body is connected to the immune system and therefore can help enhance or reduce immunity.
  • Nerves and hormones link the gut to the brain, suggesting relationships with mental health and conditions like Alzheimer’s disease.

Home Sweet Biome

The term “microbiome” has been cropping up more in recent years, and it refers to the ecosystems within the human body where bacteria, virus and fungi live. In the digestive system, many of these microorganisms cluster inside the large intestine.

Gut Feelings

  • Searches on Google for “gut health” are up by 83%, researchers from the BUPA health insurance company noted.
  • Meanwhile, Tastewise reported that searches for postbiotics rose more than 2,000% over the past two years.
  • 57% of consumers worldwide plan to improve their digestive health, according to a survey by FMCG Gurus.

Breaking It Down

  • Probiotics are microorganisms that boost good bacteria in the gut and can be consumed via certain foods, beverages and supplements.
  • Prebiotics found in food are considered “fuel” for healthy bacteria grow and thrive in the gut. Ingredients and foods rich in fiber can fall into this category.
  • Postbiotics are the waste left behind once probiotics and prebiotics are absorbed. Vitamins B and K, amino acids and short-chain fatty acids are types of postbiotics. In addition to functional purposes for the digestive tract, many of these ingredients impart other characteristics in product development – including flavor.

Consumer Interest & Common Ingredients

Keeping Tract

Today, items purporting to help with gut health are appealing to a cross-section of the food and beverage marketplace.

  • 57% of U.S. adults try to eat foods that encourage a healthy gut, Mintel reports.

Fermenting Change

As demand has come from many sides in the marketplace, some foods and ingredients have emerged as early winners in the gut health space. For instance, 10 or 15 years ago, the word “kombucha” wouldn’t necessarily roll off the tongue or be as familiar as it is today with a wide swath of consumers. Other ingredients that have become associated with digestive health claims in recent years include fermented products like kimchi, kefir, miso, sauerkraut and other substances found in nature, such as inulin-rich chicory root.
