How important is it to eat a variety of foods?


One of the healthiest lifestyle changes you could make is to include more plant foods in your weekly menu. But, it’s also crucial to make sure you aren’t eating the same foods every day. Here’s why it’s important to eat a variety of foods and some pointers for adding more plant variety to your weekly routine.


Variety is Key

Okay, so what’s the big deal about variety? Well, in one study, people who ate at least 30 forms of plant foods each week had a healthier gut environment compared to people who were eating ten or fewer types of plant foods. (Don’t freak out if that number--30!--sounds high. Lots of foods count, so keep reading!)


A healthy gut matters because it’s tied to:

  • Immune health

  • Mood regulation

  • Digestive health

  • Weight management

  • Healthy aging

Plant foods boost fiber intake

Here in the U.S., around 60% of our diet is made up of heavily processed foods, like pizza, white sandwich bread, and sugary cereal. This type of eating pattern negatively impacts the diversity of our gut microbiome and contributes to a number of diseases.


Meanwhile, the high amount of processed foods we eat also partially explains why just 5% of men and 9% of women meet their daily fiber requirements. A low fiber intake also contributes to a lack of diversity in your gut and poor gut health. When you eat a variety of plant foods, your fiber intake will go up, leading to a better gut environment.


How to eat a variety of foods

Instead of eating the same foods every day, choose numerous foods from the plant categories below.

Fruits

Don’t get into a rut eating the same fruits every day. If you only buy one or two fruits because you worry they’ll go bad, try frozen fruit. I like to keep berries, mango, and cherries in the freezer at all times! This helps me eat a variety of fruits every week.

Plant-based fats

Whenever possible, choose plant-based fats, which are healthier for your heart and gut.

  • Avocado

  • Almonds

Whole grains

Doughy white grains have been stripped of their fiber and healthy plant substances. Some vitamins and minerals are added back, but you won’t get the full benefit. That’s why these refined grains make my list of worst processed foods to eat. Obviously, you can eat these grains sometimes without worrying about it, but it’s better to eat more whole grains. (Check out my favorite whole grain cereals for more cereal diversity!)

  • Brown rice

  • Buckwheat

  • Farro

  • Millet

  • Oats

  • Quinoa

  • Sorghum

  • Whole wheat


Pulses & soy

These plant-based proteins do double duty--they also provide fiber! So add them to your weekly meal prep for more plant variety. (By the way, here are some ideas for high protein plant-based meals.)

  • Black beans

  • Cannellini beans

  • Chickpeas

  • Edamame

  • Kidney beans

  • Lentils

  • Peas

  • Pinto beans

  • Tofu


Flavor and plant boosters

Get a nutritious boost from these seasonings and beverages. They supply bioactive plant compounds that feed healthy bacteria in your gut.

  • Allspice

  • Basil

  • Cocoa

  • Cardamom

  • Chili powder

  • Cilantro

  • Cinnamon

  • Coffee

  • Cumin

  • Garlic

  • Ginger

How to eat more plant foods

Now that you see there’s a wide world of plant foods to explore, here are some tactics for adding them to your diet.

  1. Start with your favorites and try them in new ways. Already a fan of peanut butter? Use it to make a marinade for tofu or a dip for veggies. Do you like hummus? Try it as a replacement for salad dressing or instead of the cheese in a quesadilla.

  2. Try a protein swap. All you need to do is swap your typical protein source for a plant-based one. For example, instead of Greek yogurt, use silken tofu to make your next smoothie. Or try using black beans instead of taco meat sometimes. These are just a couple of the many possibilities!
