The '30 Plants a Week' Challenge and Gut Health
Eating 30 different plant-based foods each week is a dietary goal promoted by nutritionists to boost gut health. The central idea behind this target is to increase the diversity of the gut microbiome, the complex ecosystem of bacteria in our digestive tract. A diverse microbiome is linked to numerous health benefits, including improved digestion, stronger immunity, and better mental health. However, many people wonder how to count different food items, especially common staples like rice, toward this goal.
Why White Rice Doesn't Count
The reason white rice does not count toward the '30 plants' goal is its processing. White rice is made by removing the outer husk, bran, and germ from the rice grain. This process strips the grain of most of its fiber, vitamins, and minerals. What remains is primarily the starchy endosperm. Since the goal is to increase dietary fiber and feed a diverse range of gut bacteria, a highly processed food like white rice offers very little benefit in this context. While it provides carbohydrates for energy, it lacks the complex fibrous structure that the gut microbiome thrives on.
Why Brown Rice Counts (But Only Once)
In contrast to its refined counterpart, brown rice is a whole grain. This means it retains its fibrous bran and nutrient-rich germ, making it a valuable addition to a gut-healthy diet. For the '30 plants a week' challenge, brown rice would count as one plant variety. The key rule is variety, not repetition. So, regardless of whether you eat brown rice once or seven times in a week, it still only contributes a single point to your weekly tally. This principle encourages you to seek out new and different plant sources rather than relying on the same few foods repeatedly.
The Importance of Variety and Whole Foods
Beyond just rice, understanding what counts is crucial for success. The '30 plants' guideline includes several categories, each contributing to the overall diversity of your diet. This goes far beyond just fruits and vegetables.
- Wholegrains: All wholegrains count as one point. This includes brown rice, oats, barley, quinoa, and whole-wheat products.
- Legumes: Different kinds of beans, lentils, and chickpeas each contribute one point.
- Nuts and Seeds: Each distinct type of nut or seed, such as almonds, chia seeds, and pumpkin seeds, adds another point.
- Herbs and Spices: Because they are consumed in smaller quantities, each different herb and spice counts as a quarter of a point.
- Fruits and Vegetables: Each different fruit and vegetable counts as a full point. Different varieties can also count separately, such as beef tomatoes versus cherry tomatoes.
This system ensures that the focus remains on introducing a wide spectrum of plant-based foods, each with its unique blend of fibers and phytochemicals, to nourish a thriving gut ecosystem.
Comparison of Rice Types for Gut Health
| Feature | White Rice | Brown Rice | Wild Rice |
|---|---|---|---|
| Processing | Highly processed; bran and germ removed | Minimally processed; bran and germ intact | Minimally processed; harvested from marsh grasses |
| Fiber Content | Low | High | High |
| Micronutrients | Low (some added fortification) | High (B vitamins, manganese, etc.) | High (minerals, protein) |
| '30 Plants' Count | Zero | One (per week) | One (per week) |
| Gut Health Impact | Minimal | High (Feeds gut bacteria) | High (Excellent source of fiber) |
| Culinary Use | Wide variety, soft texture | Chewier texture, nutty flavor | Nutty flavor, often used in salads |
Practical Strategies for Increasing Plant Diversity
Achieving the goal of 30 different plants a week requires some planning and creativity. Instead of relying on a single staple like rice, integrate a variety of plants into every meal. Start your day with a mix of seeds and berries in your oatmeal. For lunch, add a handful of mixed beans and nuts to a salad with different leafy greens. During dinner, swap white rice for a brown rice, quinoa, or wild rice blend and load up on colorful vegetables and herbs. Even beverages like tea and coffee contribute, albeit in smaller increments. The cumulative effect of these small changes is what drives the benefits for your gut microbiome.
Conclusion
In short, the answer to "Does rice count as 30 plants?" is a resounding no, but the distinction provides a valuable lesson in nutrition. While white rice is a processed grain that doesn't contribute, whole grains like brown rice do count—but only as a single plant variety per week towards the '30 plants' goal. The true value lies in seeking out diversity, focusing on whole, unprocessed foods like brown rice, and exploring the vast world of fruits, vegetables, nuts, seeds, and legumes. By doing so, you can effectively nourish your gut microbiome and reap the long-term benefits of a truly diverse diet.

Frequently Asked Questions
Q: Why do whole grains like brown rice only count as one plant point? A: They count as one point to encourage variety. The goal is not to eat a lot of one plant, but to consume a wide range of different plant species to feed a more diverse gut microbiome.
Q: Are all nuts considered one plant point, or does each type count separately? A: Each different type of nut counts as a separate plant point. For instance, almonds, walnuts, and cashews would each contribute one point.
Q: What about herbs and spices? Do they count? A: Yes, different herbs and spices do count, but due to their small serving size, each type is often counted as a quarter of a point towards the total.
Q: Does it matter if I cook the rice or have it in a different dish? A: No, the preparation method doesn't change the counting rule. The point is to consume the whole food in its least-processed form. Brown rice counts as one point, whether it's in a pilaf or a salad.
Q: Why don't processed foods made from plants, like white bread or pasta, count? A: The processing that creates white flour and white rice removes the most beneficial parts of the plant, including the fiber and many nutrients. These refined versions do not offer the same benefits to gut health as their whole-food counterparts.
Q: Can I still eat white rice if I am following the 30 plants a week guideline? A: Yes, you can still consume white rice as part of your diet, but it will not contribute to your weekly 'plant point' total. The emphasis is on adding variety, not on strictly eliminating processed foods.
Q: Are different varieties of the same plant counted separately? A: Yes, for fruits and vegetables, different varieties can count as separate points. For example, a red bell pepper and a yellow bell pepper would each count as one point.
