Studies have shown that eating 30 different plants a week is associated with a more diverse gut microbiome, which is better for overall health. Your gut microbiome is a group of microorganisms that live in your G.I. tract and that aid with digestion. Having a healthy microbiome reduces the risk of chronic disease and cancer. It also allows you to strengthen your gut lining so that your gut can repair itself. Over time the microbiome has an effect on your metabolic health, reducing your risk for type 2 diabetes, high blood pressure, high cholesterol, and improving immune function. There is also strong evidence that your gut microbiome has a direct correlation with your mental health. Aiming for a variety of different plant sources provides different types of fibers and phytochemicals that act as prebiotics, feeding the various good microbes. By avoiding highly processed foods and feeding the good bacteria in your gut with fiber from plants, more are generated to keep you healthy.
What types of foods count toward 30 plants a week?
-Fruit
-Vegetables
-Legumes (lentils, beans, chickpeas)
-Whole grains like steel cut oats, quinoa, farro, barley
-Nuts and Seeds
-Plain popcorn (without butter or sugar)
-Dark Chocolate
If you’re already consuming an abundance of plants in your diet, keep it up! If you could use some help getting to 30 different plant sources each week, start gradually by adding 1-2 fruits or vegetables in your diet and slowly increase every few days. If you’re too ambitious and add too much fiber at once, you may experience gas, bloating, or constipation.
