Gut Health Basics - Why It Matters More Than You Think

Your gut plays a much bigger role than simple digestion. In fact, about 70% of the body’s immune system is housed in the gut, making gut health a key factor in how often you get sick and how well your body recovers. Despite this, fewer than 1 in 10 U.S. adults get enough fiber each day, one of the most important nutrients for a healthy gut microbiome. Supporting gut health doesn’t require a major diet overhaul—small, consistent choices can make all the difference.

Start with Fiber

• Aim for fiber at every meal by including fruits, vegetables, beans, oats, or whole grains.

• Include water when gradually increasing fiber as this helps prevent bloating or discomfort.

• Most Americans fall short of the recommended fiber intake, impacting not only digestion, but heart and immune health.

Support Gut Bacteria with Variety & Fermented Foods

• Include fermented foods like yogurt, kefir, sauerkraut, kimchi, or miso a few times per week; these foods naturally contain beneficial bacteria.

• Focus on variety, rotating different fiber-rich foods supports diverse gut bacteria.

• Make easy swaps, such as whole‑grain breads and pastas or adding beans to soups, tacos, or salads.

What About Supplements?

• Food comes first. Most experts agree that fiber‑rich foods should be the foundation of gut health, but sometimes supplements can help.

• Probiotic supplements can offer good benefits if you’re not getting enough in your diet.

• Talk with a healthcare provider whenever considering a regular supplement, especially if you have digestive conditions or a weakened immune system.
