We are more bacteria than we are human. The trillions of organisms living in your gut—your microbiome—dictate everything from how clear your skin is to how much serotonin (the happy hormone) you produce.

Feed the Good Guys You don't always need a pill to fix your gut. The grocery store is your pharmacy.

• Fermented Foods: These are natural probiotics. Incorporate sauerkraut, kimchi, kefir, or miso into your diet a few times a week.

• Prebiotic Fibers: These are the food for your bacteria. Garlic, onions, asparagus, bananas, and oats act as fertilizer for your microbiome.

Eat the Rainbow Diversity in your diet equals diversity in your gut. If you eat the same 5 vegetables every week, your microbiome becomes limited. Aim for 30 different plant-based foods per week (this includes herbs, spices, nuts, seeds, fruits, and veggies).

The Gut-Brain Connection Stress kills good bacteria. Taking care of your microbiome also means taking care of your mind. mindful eating, deep breathing, and adequate sleep are just as important as the food on your plate.
