Optimizing Gut Health Through Diet and Lifestyle

Cathy Kading

Welcome to part 2 of the Wellspiration series on gut health. In the quest for optimal health, the gut stands out as a first chair in the orchestra of wellness. Hopefully by now you have a solid grasp of how important the gut microbiome is for overall health. Our goal remains to share actionable and meaningful ways to improve your health. In this case, it’s gut health and caring for the gut microbiome. This week, I’m focusing on how diet and lifestyle choices lay the groundwork for a balanced and thriving gut ecosystem. Let “Optimizing Gut Health through diet and lifestyle” be your compass in the complex journey of dietary and lifestyle modifications aimed at nurturing your gut health.

The diet as a way to optimize gut health

Like so many things, a well-balanced diet is the cornerstone of a healthy gut microbiome. The symbiosis between what we eat and the trillions of microbes residing in our gut is intricate, with each choice at the dining table influencing this delicate balance. Our diet and lifestyle have the potential to optimize our gut health, so it’s imperative we are thoughtful of how we live. What you eat is literally the life and death difference for your good and bad gut bugs. Let’s explore the different ways foods helps, or hurts, the gut microbiome.

Probiotics

We first learned about probiotics from Wener Kollath in 1953, but this century, they have gained such huge popularity in the form of supplements and live foods. According to the Cleveland Clinic, probiotics are:

Probiotics are live bacteria and yeasts that have beneficial effects on your body. These species already live in your body, along with many others. Probiotic supplements add to your existing supply of friendly microbes. They help fight off the less friendly types and boost your immunity against infections.

We still don’t know exactly how this works, but we do know that they are effective in a multitude of areas. According to a study in Frontiers in Microbiology, probiotics have helped improve the gut barrier, improve the immune system and help support reduction of high blood pressure and cancer risk. I like to think of Probiotics as the maintenance staff for the Palace of Versailles. They take care of things before they break and help repair things that go sideways. As you might expect, the palace is complex and needs adequate staff to support all the work required to maintain the buildings and gardens. Not having enough staff would result in the place falling into disrepair at best, and ruin at worst.

Prebiotics

Nodding to the “Pre” in prebiotics, it tells us it comes before probiotics. In case you forget, putting them in alphabetical order will help you remember. According to the National Institute of Health, prebiotics are “a group of nutrients that are degraded by gut microbiota. [They] feed the intestinal microbiota.” Research on prebiotics is much more nascent than probiotics, as we only became familiar with them in the 1990s. As a result, we don’t have as much data about them. However, the simple explanation is that they feed the good bacteria in the gut. If the probiotics are the maintenance staff of the gastrointestinal Palace of Versailles, then prebiotics are all the food & water needed to keep the maintenance staff happy and working.

More than fiber

Fiber typically takes center stage in gut health, but other nutrients play crucial roles, too. Summarized from a Duke University School of Medicine finding, “[Fiber] is crucial to gut health because it feeds the beneficial microbes in our gut. This leads to the production of short-chain fatty acids like butyrate, which protect against diseases, lower inflammation, and improve the health of the intestinal lining.” However, fiber is just one component. According to a 2017 meta study, Omega-3 fatty acids, found in wild-caught fatty fish, flaxseeds, and walnuts, have been shown to “exert significant effects on the intestinal environment.” Zinc, another critical element, present in meat, shellfish, and legumes, has been shown to maintain the integrity of the gut lining.

Dietary diversity as a way to optimize gut health

Embracing a wide array of fruits, vegetables, whole grains, and lean proteins ensures a diversity of nutrients and prebiotics, fostering a robust microbiome. While “eat the rainbow” may be the tag for Skittles, there is no better way to naturally improve gut health. Not only do you increase trace minerals, you increase antioxidant and vitamin intake, all contributing to optimal gut health. A healthy gut also guards against chronic diseases by promoting a rich and resilient microbial community, so eat up.

The lifestyle path to optimal gut health

I would be remiss if I didn’t address the impact of our lifestyle on gut health. Things like stress management, sleep quality, physical activity, and exposure to environmental toxins all impact gut health. It may seem counterintuitive but when we aren’t happy, neither are our beneficial gut bugs. Part of the reason is because when we are stressed, we make fewer decisions in honor of our gut health, but it’s so much more.

Stress and the Gut: An Unseen Connection

Chronic stress can wreak havoc on the gut, disrupting microbial balance and increasing vulnerability to digestive disorders. Incorporating stress-reduction techniques such as meditation, yoga, or regular exercise can mitigate these effects, promoting a healthier gut environment. According to research by Dr. Howard Mertz of Vanderbilt University, “[stress] negatively impacts the gut microbiota by altering gastrointestinal function, leading to symptoms like heartburn, indigestion, and changes in bowel habits. It triggers the release of stress hormones [cortisol] that modify gut motility and sensitivity, potentially worsening conditions like irritable bowel syndrome (IBS) by increasing gut contractions and sensitivity.” If you want more on stress management, check out the Wellspiration stress management series ([1], [2], [3], [4], [5]).

Hacking your sleep for optimal gut health

Quality sleep is as nourishing to the gut as it is to the mind and body. Disrupted sleep patterns have been linked to unfavorable shifts in gut bacteria. We aren’t exactly sure how yet, but there is growing research about how poor sleep reduces microbiota flora. According to studies, microbiome diversity is positively correlated with better sleep efficiency and longer total sleep time. This implies sleep disruptions may affect the gut microbiome’s diversity indirectly, by altering sleep patterns. As a result, this impacts the microbiome’s health and diversity. Prioritizing 7-9 hours of restful sleep nightly can significantly benefit your beneficial microbes.

Practical diet and lifestyle tips for optimal gut health

Implementing changes to enhance gut health doesn’t require a complete lifestyle overhaul. Even small changes can yield significant benefits, which is where health coaching can really support you. Below are a few things to consider.

Simple Dietary Changes

There are so many ways to start incorporating more whole foods into your meals. Think of it as an experiment and challenge yourself to get really creative. Here is a quick list of ways you can incorporate small dietary changes:

Try adding one new vegetable to your rotation every week.
Swap out one processed snack at a time with for seeds, nuts, or berries.
Experiment with fermenting vegetables at home or adding a serving of probiotic-rich food to one meal a day.
Try a fermented beverage like kefir or kombucha
Incorporate new types of foods like Indian, Korean or Moroccan. These cuisines are loaded with anti-inflammatory spices, fermented foods, and prebiotics that aren’t normally found in a Standard American Diet (SAD).
Incorporate the rainbow, and I’m not talking about Skittles here. Eat fruits and veggies of all different colors. How many colors have you tried?

Lifestyle Adjustments

Like our diet, there are small and incremental changes you can incorporate to improve gut health. Here are a few ways you can start loving your gut with little effort:

Dedicate time for physical activity daily, even if it’s a quick 30-minute walk.
Create a bedtime routine to improve sleep hygiene.
Find stress-reduction practices that fit into your schedule and preferences ([1], [2], [3], [4], [5]).
Start incorporating mindfulness practices into your daily routine. Play with a minute at a time and see how how you feel.
