The condition of your gut affects your overall health. To be more specific, your microbiome is what’s driving your gut health. But what does all of this mean?

Your “gut” refers to your gastrointestinal tract (or GI tract, for short). It includes all parts of the body that you use to digest, absorb and process food. It starts with your mouth, salivary glands, throat (pharynx) and esophagus. It progresses to your stomach, liver, pancreas, gallbladder, small intestine, large intestine and rectum and ends with your anus.1

Your microbiome consists of a variety of things best kept for science class. There are microorganisms, bacteria, viruses, protozoa, fungi and genetic material living in your gut.2 The balance is delicate and affected by many factors. An imbalance can change your metabolism and cause inflammation.3 While some bacteria may be harmful, nearly all of the bacteria in your gut is helpful and necessary.

As you age, your microbiome evolves. It’s affected by many things, from genetics to what you eat. There is a suggested correlation between diverse microbiomes and living longer, more active lives.2

Improve your gut health

Diversifying your diet is the first step to take. Commit to regular, healthy eating habits. Skip the salty, sugary, fatty and processed foods. Instead, enjoy fiber and nutrient-rich foods like:

  • A wide variety of fruits and veggies–the fresher the better
  • Fiber-rich nuts, seeds and legumes
  • Whole-grain foods like 100% whole-grain bread, brown rice, whole rolled oats, millet and quinoa

What are probiotics? Probiotic foods contain live microorganisms that boost the good bacteria in your gut.4 They are found in fermented foods like:

  • Yogurt
  • Kefir
  • Kimchi
  • Sauerkraut
  • Miso
  • Kombucha

How about prebiotics? These fiber-rich foods feed the helpful probiotic organisms in your gut:5

  • Asparagus
  • Citrus fruits
  • Berries
  • Bananas
  • Apples
  • Steel-cut oats
  • Onions
  • Garlic
  • Almonds

Combine your favorite prebiotic, probiotic and natural, unprocessed foods to shape up your microbiome. Your health could benefit from it. And try this delicious recipe full of natural goodness.
