Dietitians Recommend Simple Dressing Trick for Better Gut Health

Replacing your usual salad dressing base with plain yogurt could make your greens and legumes even more gut-friendly. Yogurt with live cultures can add probiotics, beneficial microorganisms that can support digestive health, without changing the contents of your salad. While this simple tip can provide benefits, your gut health depends on several dishes.

Use natural yogurt to prepare your vinaigrette

The next time you make a homemade salad dressing, you may not need mayonnaise or another creamy base. Instead, Carlyne Remedios, RD, a registered dietitian at JM Nutrition, recommended using plain yogurt.

“The live cultures in yogurt may help maintain a healthy gut microbiome by increasing beneficial gut bacteria, improving the variety of microbes in the gut, and reducing some potentially harmful bacteria,” she tells Verywell. A healthy balance of gut microbes can, in turn, support digestion, immune function, and a healthy intestinal lining.

Ramona Ramdath, RD, PhD, a registered dietitian at Meniere’s Dietitian, said you can add other ingredients to your gut dressing, including onion, garlic, or leeks. These three vegetables provide prebiotic fiber that your body cannot digest on its own. Instead, these fibers travel to your large intestine, where they feed beneficial bacteria and help them grow.

When these bacteria break down fiber, compounds called short-chain fatty acids are produced. These fatty acids nourish the cells that line your colon, support the intestine’s protective barrier, and help control inflammation, Ramdath explained.

To create a gut-healthy salad dressing, mix plain yogurt with live, active cultures, minced garlic, lemon juice and your favorite herbs. Then pour a little water or olive oil to dilute it. You can also opt for extra virgin olive oil, which can help your body absorb fat-soluble nutrients from your salad.

This Dressing Trick Won’t Dramatically Change Gut Health

Adding yogurt and prebiotic-rich ingredients to your salad dressing is a smart way to support your gut. But don’t expect dramatic changes with just one dish.

The benefits depend on the ingredients you use and how often you eat the salad. Not all yogurts contain the same live cultures, and the amount of garlic or onion in a typical serving of salad dressing may not provide enough prebiotic fiber to make a noticeable difference on its own.

Meanwhile, garlic and onions contain fermentable carbohydrates that can trigger gas, bloating, and other digestive symptoms in some people, especially those with irritable bowel syndrome (IBS). So it’s perfectly okay to avoid these vegetables if they tend to upset your stomach.

Overall, your gut microbiome responds to your overall eating habits, not just a single ingredient. Eating a variety of fiber-rich foods, including fruits, vegetables, legumes, and whole grains, helps feed different types of beneficial bacteria. Fermented foods like yogurt can add live microorganisms to the mix.
