Support a Healthier Gut: What a Week of Eating Like a Dietitian Actually Looks Like

By Lizzie Streit, MS, RDN, LD

With gut health as a hot nutrition topic for the past several years, you’ve probably heard about juice cleanses, detox teas, or restrictive meal plans that offer a gut “reset” in a short period of time. It’s easy to see why these offerings are intriguing, especially since a healthy and diverse gut microbiome can support weight loss and actually boost the efficacy of GLP-1 medications.

But in reality, the dietitian-endorsed method of supporting a healthy gut is a lot less dramatic. The gut microbiome thrives on consistent habits that nourish beneficial bacteria. It doesn’t need fancy supplements and, instead, can be fueled by everyday foods. If you’re curious about what to eat to support gut health, here are three essential habits to implement and a snapshot of a week of dietitian-approved meals.

1 – Eat plants at nearly every meal.

Current research suggests that eating 30 different plant foods each week is associated with a more diverse gut microbiome compared to eating fewer than 10 plants. This goal may sound overwhelming at first, but you can gradually work towards it by adding plants at almost every meal. Plus, “plant foods” include fruits and vegetables but also beans, nuts, seeds, herbs, and spices.

Add berries to breakfast, snack on fruit and nuts, eat a salad with leafy greens for lunch, and season your dinner with fresh herbs. If you need some help, consider a healthy meal delivery service like Healthy For Life Meals that does the work of choosing and prepping plant foods for you.

2 – Prioritize fiber.

Adding more plants to your diet will naturally increase your fiber intake, but it’s an important enough nutrient that it deserves its own mention too! Most Americans fall short on the recommended intakes for dietary fiber, which range from 25 to 38 grams per day depending on age and sex. Getting enough fiber helps feed beneficial bacteria in the gut and supports healthy digestion and bowel movements.

Having a target number in mind can help you make informed decisions about what to add to your diet. A few fiber-rich options to eat for better gut health include raspberries (1 cup=8 grams) and black beans (1 cup=16 grams).

3 – Include fermented foods.

Evidence suggests that regular consumption of fermented foods is linked to increased microbial diversity in the gut. These include yogurt, fermented cottage cheese, kefir, fermented vegetables (like kimchi and sauerkraut), miso, and kombucha. While you don’t need to eat these at every meal, consider adding them to your diet a few times a week for potential gut health benefits.
