Understanding the '30 Plants a Week' Goal
Eating 30 or more different plants a week is a goal popularized by nutrition experts like Professor Tim Spector, based on findings from the American Gut Project. The principle is simple: greater plant diversity in your diet correlates with a more diverse and robust gut microbiome. This translates to better digestion, a stronger immune system, and improved metabolic and mental health. The 'plants' counting towards this goal are not limited to fruits and vegetables but also include a wide array of other plant-based foods.
What Counts as a 'Plant'?
To achieve the target, you must count different varieties from several food groups. A single food item of one type per week counts as one 'plant point,' regardless of how often you eat it. Different colored peppers count as separate plants, and so do mixed beans or nuts.
- Vegetables: Leafy greens (spinach, kale, arugula), root vegetables (carrots, beetroot, parsnips), brassicas (broccoli, cauliflower, cabbage), alliums (onions, garlic, leeks), and other veggies (bell peppers, mushrooms, avocados). Frozen, tinned, and fermented vegetables all count.
- Fruits: A wide variety, including berries, citrus, apples, bananas, and exotic fruits. Dried and frozen fruits are also included.
- Whole Grains: Whole wheat pasta, oats, brown rice, quinoa, barley, and millet.
- Legumes: Lentils (red, green, puy), beans (black, kidney, cannellini), chickpeas, and peas.
- Nuts and Seeds: Almonds, walnuts, cashews, pumpkin seeds, chia seeds, and flaxseed.
- Herbs and Spices: Fresh and dried varieties like basil, cilantro, parsley, thyme, cinnamon, cumin, and ginger. Due to smaller serving sizes, some tracking methods count four different herbs/spices as one 'plant point'.
- Others: Minimally processed dark chocolate (over 70% cocoa), coffee, and tea.
Simple Strategies to Boost Plant Diversity
Reaching 30 plants doesn't have to be overwhelming. Small, consistent changes can make a huge difference.
- Mix it up: Swap single ingredients for mixed varieties, such as a mix of salad leaves instead of just iceberg lettuce, or a mixed bean medley instead of a single bean type.
- Soup and Smoothie Boosters: Add a handful of greens, nuts, seeds, and spices to soups and smoothies to quickly increase your daily count.
- Batch Cook: Prepare large batches of hearty soups, stews, or chilis using numerous vegetables, lentils, and spices, which can be enjoyed throughout the week.
- Season Generously: Don't underestimate the power of herbs and spices. Add fresh or dried herbs to almost every dish for extra flavor and plant points.

Comparison Table: 30-Plant Meal Plan vs. Standard Diet
| Feature | 30-Plants a Week Meal Plan | Standard Western Diet |
|---|---|---|
| Focus | Maximizing diversity of plant foods. | Often limited to a few staple vegetables and grains. |
| Gut Health | High diversity of gut microbes linked to positive health outcomes. | Lower microbial diversity, potentially linked to health issues. |
| Fiber Intake | Naturally higher, with a wide range of fermentable fibers. | Often insufficient, relying on a few sources. |
| Nutrient Variety | Access to a broader spectrum of phytochemicals, vitamins, and minerals. | Limited variety of nutrients from a narrow range of plants. |
| Meal Complexity | Requires mindful planning but leads to more flavorful, nutrient-dense meals. | Can be repetitive and less nutrient-dense. |
Making the Shift: Tips and Tricks
Transitioning to a more diverse, plant-rich diet is a journey, not an overnight change.
- Track Your Progress: Create a simple chart or use a habit-tracking app to list the unique plants you consume each week. It's a satisfying way to visualize your progress.
- Embrace Frozen and Tinned: Don't feel you must only use fresh produce. Frozen mixed vegetables, berries, and tinned chickpeas or beans are affordable and convenient ways to add variety.
- Explore New Cuisines: Many global cuisines naturally feature a wide variety of plants. Experiment with recipes from Indian, Thai, or Mexican traditions to discover new spices and legumes.
- Don't Stress Over the Number: If you fall short of 30 one week, don't worry. Focus on improvement, not perfection. Every extra plant you add is a win for your gut.
