Sprinkle Your Way to a Happier Gut: The Diversity Jar Hack

If the wellness world has a buzzword right now, it’s gut health. It’s the golden child of nutrition trends, right up there with protein-packed everything and “what’s in my smoothie” videos. But unlike some trends that fizzle out (remember charcoal lattes?), this one has some serious science backing it up. And the latest hack people are raving about? A humble little kitchen trick called the diversity jar.

Wait—what even is gut health?

“Gut health” might sound like one of those nebulous wellness catchphrases, but it’s got a very real foundation. As the American Medical Association explains, gut health “refers to the well-being of the digestive system, which is responsible for breaking down food, absorbing nutrients, and eliminating waste from the body.”

At the center of this whole operation is the gut microbiome—a bustling community of microorganisms that don’t just help with digestion, but also strengthen your immune system and even influence your nervous system via the gut-brain axis. Basically, your gut is like the command center of your body, and the microbes running it thrive on variety.

Enter: the diversity jar

So how do you keep those microbes happy and balanced? Some social media users (and a few very enthusiastic scientists) say the answer could be sitting in your pantry.

Tim Spector, MD — professor of epidemiology at King’s College London, scientific co-founder of personalized nutrition service ZOE, and the man credited with popularizing the idea — explains that a diversity jar “is essentially a homemade mix of plant ingredients — think nuts, seeds, spices, dried herbs, grains, and even pulses — that you can sprinkle onto meals to boost the diversity of plants in your diet.”

Think of it as a secret weapon jar filled with shelf-stable, plant-based goodies you can toss onto almost anything. Yogurt? Sprinkle. Salad? Sprinkle. Curry? Sprinkle. You get the picture.

The beauty is in its simplicity: you’re giving your gut a buffet of plants in one spoonful. And according to Spector, “starting with a spoonful a day” is all it takes to begin.

Why does it matter?

The “diversity” part of the jar isn’t just a cute name—it’s the whole point. Research shows that eating a wider variety of plants fosters a more diverse microbiome, which is linked to better digestion, stronger immunity, and improved overall health. Spector has even recommended aiming for at least 30 different plants each week.

Lisa Moskovitz, RD, founder of NY Nutrition Group and author of The Core 3 Healthy Eating Plan, says the biggest perk of a diversity jar is “introducing more gut-friendly fiber and antioxidants.” Plus, many of the nuts and seeds you’ll toss in “pack in plenty of other great nutrients like magnesium, iron, potassium, and omega-3 fatty acids.” In other words, it’s a small sprinkle with a big payoff.

How to make your own diversity jar

Here’s the fun part: building your jar is basically like creating your own edible trail mix for meals.

• Start with a base: Flax seeds, hemp hearts, black sesame, pumpkin seeds, rolled oats, or quinoa flakes.

• Add some crunch: Any nuts will do. (Pro tip: chop or pulse the bigger ones like cashews or pecans so they blend in easily.)

• Spice it up: Dried herbs, turmeric, cinnamon, or even a dash of chili flakes.

• Get fancy (if you want): Adaptogens like maca or ashwagandha for those who like to dabble in the trendy aisle.

Spector advises steering clear of “anything highly processed or sweetened… The key is to keep it plant-based and well-balanced, with textures and flavors that enhance your meals rather than overpower them.”

And remember, this isn’t about making one perfect jar for eternity—it’s supposed to be playful. Some combos will be knockout winners you’ll sprinkle on everything, others maybe not so much. The point is: your gut bugs love variety, and so should your jar.

The takeaway

Gut health isn’t just hype—it’s a foundation of how your body functions, from digestion to immunity to brain health. And the diversity jar is one of the easiest, most low-lift ways to give your gut the variety it craves. One spoonful, a sprinkle here and there, and suddenly your meals aren’t just tastier—they’re microbiome-friendly too.

So grab a jar, raid your pantry, and get mixing. Your gut (and probably your taste buds) will thank you.
