What is the 30 plants a week checklist? Your Ultimate Guide to a Healthier Gut

4 min read

A 2018 study from the American Gut Project found that people eating 30 or more different types of plants a week had a significantly more diverse gut microbiome compared to those eating fewer than 10. This finding is the basis for the popular health goal known as the 30 plants a week checklist.

Quick Summary

The 30 plants a week challenge focuses on consuming a variety of plant foods, including grains, legumes, nuts, seeds, herbs, and spices, to promote a diverse gut microbiome and improve overall health.

Key Points

  • Origin: The concept of eating 30 plants a week stems from research by the American Gut Project, which found a strong link between dietary diversity and a more diverse, healthier gut microbiome.

  • Beyond Fruits & Veggies: Your plant count includes whole grains, legumes, nuts, seeds, herbs, and spices, making the goal more attainable than it sounds.

  • Variety over Volume: The focus is on the diversity of plants, not the quantity of each portion, allowing for flexibility and preventing monotony.

  • Gut Health Benefits: A diverse gut microbiome, supported by a varied diet, is associated with better digestion, stronger immunity, and reduced inflammation.

  • Easy Hacks: Simple strategies like adding seeds to yogurt, blending diverse smoothies, and using more herbs and spices in cooking can quickly boost your weekly plant count.

  • Track Your Progress: Keeping a simple checklist helps you stay mindful of your intake and makes achieving the 30-plant goal a fun and engaging habit.

What is the 30 Plants a Week Checklist?

The 30 plants a week checklist is a dietary goal rooted in research suggesting that consuming a wide variety of plant foods significantly enhances gut microbiome diversity. Popularized by experts like Professor Tim Spector of ZOE, this concept shifts the focus from simply eating more fruits and vegetables to emphasizing variety. The core idea is that different types of plants contain unique fibers and polyphenols that feed different beneficial bacteria in your gut. By diversifying your plant intake, you create a more robust and resilient microbial community, which is linked to better digestion, improved immune function, and reduced inflammation. This approach counts all plant-based foods, from everyday items to herbs, spices, and even coffee.

Why a Diverse Diet is Crucial for Gut Health

Your gut microbiome is a complex ecosystem of trillions of microorganisms. A diverse array of these microbes is a key indicator of good gut health. When you eat a limited range of plants, you only feed a small number of bacterial species, which can lead to an imbalanced or less resilient microbiome. Conversely, a varied diet provides a broader spectrum of nutrients, fueling a wider range of beneficial bacteria. These bacteria, in turn, produce beneficial compounds like short-chain fatty acids (SCFAs) that nourish the colon lining and reduce inflammation. Research has also shown links between a diverse gut microbiome and improved metabolic health, cognitive function, and protection against pathogens.

The Six Main Plant Groups

To make tracking your weekly plants easier, think in terms of the following six categories. Any whole or minimally processed plant counts, and different varieties or colors of the same plant (e.g., red and yellow peppers) can count as separate points.

  • Vegetables: Include leafy greens (spinach, kale), root vegetables (carrots, beets), alliums (onions, garlic), brassicas (broccoli, cabbage), and more. Don't forget preserved vegetables like pickles or olives.
  • Fruits: Explore berries, citrus fruits, apples, bananas, avocados, tomatoes, and dried fruits like raisins.
  • Whole Grains: Swap refined grains for whole varieties such as oats, brown rice, quinoa, barley, and farro.
  • Legumes: Incorporate beans (black, kidney, cannellini), lentils (red, green), chickpeas, and edamame. Tinned or dried legumes are perfect additions.
  • Nuts and Seeds: Snack on or add nuts (almonds, walnuts, pecans) and seeds (chia, flax, pumpkin) to meals.
  • Herbs and Spices: Fresh or dried herbs like parsley, basil, and cilantro, and spices like turmeric, cumin, and ginger, all add to your count. These offer potent plant compounds.

Comparison: 30 Plants vs. 5-a-Day

Feature 30 Plants Per Week 5-a-Day
Primary Goal Variety over quantity to boost gut microbiome diversity. Quantity of fruits and vegetables for general nutrition.
Counts as a 'Plant Point' All plant-based foods, including grains, legumes, herbs, and spices. Fruits and vegetables only. A small portion equals one of the five.
Source of Idea American Gut Project study demonstrating higher microbiome diversity with increased plant variety. World Health Organization recommendation based on overall health benefits of fruits and vegetables.
Flexibility Higher flexibility due to a broader range of foods counting towards the goal. More rigid focus on fruit and vegetable portions.

How to Easily Reach 30 Plants

Integrating 30 different plant foods into your weekly diet is simpler than it sounds. Start with a few small changes and build from there.

  1. "Supercharge" Your Breakfast: Add mixed berries, chia seeds, and walnuts to your oatmeal or yogurt.
  2. Make Sauces More Diverse: Include onions, garlic, and several spices like cumin and paprika into your pasta sauces or stews.
  3. Boost Your Salad: Combine multiple types of leafy greens (spinach, arugula), add chickpeas or lentils, and top with various seeds and fresh herbs.
  4. Snack Intelligently: Swap a standard snack for a handful of mixed nuts and seeds, or hummus with assorted veggie sticks.
  5. Utilize Your Freezer: Keep a stock of different frozen vegetables, which are just as nutritious and prevent food waste.
  6. Drink Smarter: Enjoy a cup of coffee or herbal tea, both of which contribute to your plant count.

How to Create Your Own 30 Plants a Week Checklist

The most effective way to track your intake is by creating your own simple list for the week. You can use a notepad, a note-taking app, or a printable chart. As you eat or use a new plant ingredient, simply write it down. This process keeps you mindful of your intake and encourages you to discover new, interesting ingredients. Remember that even a pinch of a spice or a few seeds in your salad counts. It's about a consistent and varied approach, not perfection.

Conclusion

Adopting the 30 plants a week challenge is a powerful and accessible strategy for improving your gut health and overall well-being. By focusing on dietary diversity across a wide range of plant categories, you nourish a more resilient and balanced gut microbiome. The concept is based on solid scientific research and provides a flexible framework that goes far beyond the traditional 5-a-day rule. With simple meal additions, smart snacking, and mindful tracking, reaching this goal can be an enjoyable and rewarding journey toward a healthier you.
