I’m a big fan of Dr. B (Will Bulsiewicz). He’s approachable, positive, knowledgeable, and compassionate, and I always look forward to his new books. In Plant Powered Plus, he expands on the gut microbiome and highlights the importance of also addressing and healing the gut barrier and immune system. Together, he calls these our “legendary triad of bodily defenders.”
The book is broken down into three parts:
Part 1: Foundations of Inflammation
Part 2: The Pillars of Gut-Immune Health
Part 3: From Knowledge to Action, and Inspiration to Transformation
In my opinion, the first part felt somewhat like a review of material covered in his earlier work, but I particularly appreciated the chapter on our toxic environment.
Part 2 offers plenty of practical tips. I especially enjoyed the chapter on “The Four Nutrition Workhorses,” with fibre and polyphenols taking the top two spots on the list. Healthy fats come in at number three. Viewed through the lens of a whole-food plant-based nutritionist, I wasn’t entirely convinced by the emphasis on olive oil. That said, I appreciate that Dr. B. aims to meet people where they are, and every step toward healthier eating is a win. There’s no question that extra virgin olive oil is preferable to many other oils, but there are also plenty of ways to cook and enjoy food without adding it. The fourth pillar is fermented foods, of which I’m also a big fan. Ideally, everyone would include one or two fermented foods in their daily diet.
Dr. B. also discusses supplements. While I agree with some of his suggestions, vitamin D, for example, it’s worth approaching these recommendations with a bit of caution. He does have a vested interest in supplements, as he serves as the U.S. Medical Director of Zoe, a health app and supplement company. He does disclose this relationship, but it’s something readers should keep in mind.
By far, the part of the book that will likely appeal most to readers is the final section: “The Plant-Powered Plus Protocol.” Here, Dr. B. outlines a three-phase plan: Baseline, Growth, and Mastery. Within each phase, he provides nutritional guidelines, weekly meal plans, and a daily checklist that includes practices such as getting sunlight and doing breathwork. The final 100 pages of the book are dedicated to recipes, 52 in total.
Overall, this was an enjoyable read and one I will recommend to my clients. The book strikes a nice balance between science and practical guidance, making complex concepts accessible to everyday readers. If you are struggling with inflammation or gut issues, there’s a good chance that Dr. B.’s protocol could help support your healing journey.
