What counts towards 30 plants per week? A guide to boosting your gut health

4 min read

According to the American Gut Project, individuals who consume 30 or more different plant-based foods per week have a significantly more diverse gut microbiome than those who eat 10 or fewer. This is why knowing exactly what counts towards 30 plants per week is essential for optimal digestive and overall wellness.

Quick Summary

This article details the categories of food that contribute to your weekly 30-plant goal, including fruits, vegetables, whole grains, nuts, seeds, herbs, and spices. It explains how to track your progress and provides practical strategies for diversifying your diet.

Key Points

  • Diverse food categories: The 30 plants per week goal includes fruits, vegetables, whole grains, legumes, nuts, seeds, herbs, spices, and more.

  • Variety over volume: The focus is on eating a wide variety of different plants, not consuming large portions of a few specific ones.

  • Different colors count: Different colors of the same fruit or vegetable, like red and yellow bell peppers, count as separate items.

  • All forms count: Fresh, frozen, canned, and dried versions of plants are all eligible for your weekly count.

  • Unexpected additions: Items like coffee, dark chocolate (70%+), and tea also contribute to your total because they come from plants.

  • Track weekly, not daily: Count each unique plant item only once per week, even if you eat it multiple times.

  • Power of herbs and spices: Adding different herbs and spices is an easy way to increase your plant diversity with minimal effort.

  • Small amounts are fine: You don't need a large serving of a plant for it to count, so a sprinkle of seeds or a dash of spice is perfectly valid.

  • Refined foods don't count: Highly processed items like white flour products and fruit juices are excluded from the count.

Understanding the 30 plants per week concept

The goal of eating 30 different types of plant-based foods per week is rooted in the science of the gut microbiome. The gut is home to trillions of microorganisms that play a crucial role in everything from digestion and immunity to mood regulation. These microbes thrive on a diverse array of plant fibers and compounds. The more variety you consume, the more diverse your gut bacteria become, leading to a healthier gut and better overall health outcomes. The good news is that reaching this target is more manageable than it sounds, as it includes a wide range of food categories, not just fresh fruits and vegetables.

Breaking down the plant categories

To understand what counts towards 30 plants per week, it's helpful to break down the eligible food groups. Each unique plant item within these categories counts towards your total for the week.

  • Fruits: All fruits, whether fresh, frozen, dried, or canned, count. Different colors of the same fruit, such as a red and a green apple, can be counted as two separate items. This is because the varying colors often signal different types of beneficial plant compounds called polyphenols.
  • Vegetables: This includes everything from leafy greens and root vegetables to alliums and salad leaves. Like fruits, different colors of the same vegetable, such as a red and a yellow bell pepper, can be counted separately. This category also includes unexpected items like potatoes, mushrooms, and seaweed.
  • Whole Grains: Refined grains like white bread and white rice do not count, but whole grains retain their fiber-rich bran and germ. Examples that contribute include oats, brown rice, barley, quinoa, and whole wheat.
  • Legumes: This category includes all beans, lentils, and peas, both dried and canned. Variety is key here, so a mixed-bean salad with chickpeas, black beans, and kidney beans would count as three items.
  • Nuts and Seeds: A wide variety of nuts and seeds, as well as their butters, are included. Think almonds, walnuts, chia seeds, flaxseeds, and even peanut butter.
  • Herbs and Spices: This is a powerful and often overlooked category for adding diversity. Both fresh and dried herbs and spices count, and a good rule of thumb is to count a quarter point for smaller amounts, but every different type counts.
  • Other Plant-Based Items: Several plant-derived products also contribute to your count. These include high-quality dark chocolate (70% cocoa or higher), coffee, and tea. Some fermented foods, like kimchi and sauerkraut, made from plants, also provide both diversity and probiotics.

Practical strategies for hitting your 30-plant goal

Achieving 30 plants per week doesn't require overhauling your entire kitchen at once. Incremental changes and smart meal planning can help you build your diversity count naturally over the week.

Comparison table: Boosting your plant count

Meal Component Traditional Choice Plant-Boosting Swap Plant Count Increase
Breakfast A bowl of plain oatmeal Oatmeal topped with blueberries, walnuts, and chia seeds +3 (blueberries, walnuts, chia seeds)
Lunch Chicken and white rice Black bean and corn salad with bell peppers, onion, and cilantro +4 (black beans, corn, bell peppers, cilantro)
Dinner Plain spaghetti with jarred tomato sauce Lentil and vegetable marinara sauce with onion, garlic, carrot, celery, and basil +5 (lentils, onion, garlic, carrot, celery)
Snack A single type of fruit A handful of mixed nuts, seeds, and dried fruit +3 (mixed nuts, pumpkin seeds, raisins)

Making it a simple and sustainable habit

  • Shop Smarter: When grocery shopping, prioritize variety. Choose mixed bags of frozen vegetables or stir-fry mixes, which often contain several different plants. Similarly, select a mixed bag of nuts and seeds rather than just one type.
  • Embrace the Store Cupboard: Canned items like chickpeas and three-bean mixes are an affordable way to add instant plant diversity. Stock up on various spices and herbs to sprinkle into meals throughout the week.
  • Batch Cook: Prepare a large pot of vegetable and legume-rich soup or a mixed vegetable curry at the beginning of the week. You can add different herbs and spices each day to boost the count.
  • Liven Up Your Meals: Turn a simple meal into a plant-powered one by adding simple toppings. Sprinkle mixed seeds on your salad or yogurt, add fresh herbs to your eggs, or toss a handful of different colored peppers into a stir-fry.
  • Try Meatless Mondays: Dedicating one day a week to plant-based meals can introduce you to new legumes, vegetables, and tofu, significantly boosting your weekly count.
  • Utilize Smoothies: Smoothies are an excellent vehicle for variety. Blend in mixed frozen berries, a handful of spinach, a spoonful of nut butter, and some ground flaxseed for an easy four or more points.

A conclusion on dietary diversity

The pursuit of 30 plants per week is not about strict dietary rules but about embracing culinary creativity and diversity for better health. Research has shown that prioritizing a wide array of plant-based foods, rather than focusing on a single, restrictive plan, provides the most significant benefits for your gut microbiome. By making small, intentional changes to incorporate different fruits, vegetables, whole grains, nuts, seeds, herbs, and spices into your weekly meals, you can nourish your body and promote a more resilient, thriving inner ecosystem. This approach shifts the focus from limitation to abundance, proving that a healthy diet can be both delicious and incredibly diverse.

Frequently Asked Questions

The recommendation is based on findings from the American Gut Project, which showed that people who ate 30 or more different types of plants a week had a more diverse gut microbiome compared to those eating 10 or fewer. A diverse microbiome is linked to improved digestive health, stronger immunity, and other positive health outcomes.

Yes, different colors of the same fruit or vegetable typically count as separate items. For example, a red bell pepper and a yellow bell pepper would be counted as two unique plants because they contain different phytonutrients.
