1. The Diet Myth by Tim Spector
About the Book: The efficacy of food is derived from all the components in natural food and the thousands of metabolic by-products that occur during the interaction between food and food and microbes in the body. (So most of the health products on the market are useless)
The more varied the diet and the richer the gut flora, the better the health. This applies to anyone of any age.
Key Points:
- Increase the diversity of food, which is conducive to the growth of intestinal flora. Learn the Mediterranean diet, adding whole grains, olive oil, all kinds of fresh fruits and vegetables, nuts, red wine, fish, and dairy products;
- Eat more organic food and reduce the indirect intake of antibiotics and hormones. Antibiotics will greatly reduce intestinal microorganisms;
- Be wary of sugar in processed foods; sweeteners are just as bad, disrupting the function of gut flora, negatively impacting metabolism, and thus endangering health.
- Dark chocolate containing 70% cocoa is good for health. People who eat chocolate often have healthier metabolism and intestinal flora.
- Drinking a cup of coffee in the morning can wake up the microorganisms in the body. Coffee contains polyphenols and cellulose, while tea has no cellulose.
- Regularly drinking a small amount of alcohol can greatly increase the types of gut microbes.
- As long as no salt is added, eating 30 grams of mixed nuts a day has a significant reduction in the risk of heart disease compared with the low-fat diet group, which is almost equivalent to the additional consumption of olive oil.
- Proper fasting and learning to starve can reduce body fat and stress-related cortisol levels.
PS: I have always been proud of myself, thinking that I have strengthened my heart. The resting heart rate has dropped from more than 70 to 55 now, and the function has become stronger, but I did not realize that this also means that consumption is slowed down. So, everything is too much, and self-examination.
2. Spoon-Fed by Professor Tim Spector
About the Book: Is salt really bad for you? Is fish good for you? What about coffee, red meat, or saturated fats? Can pregnant women rely on their doctor's advice about what to eat? Does gluten-free food carry any health benefits at all? Do doctors know anything about nutrition?
In the course of the research, Tim Spector has been shocked to discover how little scientific evidence there is for many of our most deeply rooted ideas about food.
In twenty-two short, myth-busting chapters, he reveals why almost everything we've been told about food is wrong. He reveals the scandalous lack of good science behind many medical and government food recommendations, and how the food industry holds sway over these policies and our choices.
These are urgent issues that matter not just for our health as individuals but for the future of the planet. Spoon-Fed forces us to question every diet plan, official recommendation, miracle cure, or food label we encounter and encourages us to rethink our whole relationship with food.
If you don't know anything about nutrition, this book can still be read. Since I have covered a lot of lessons in this area in recent years, I found that there is nothing new in this book.
I am skeptical about the author's argumentation method: for example, to demonstrate the benefits of coffee, it is repeatedly emphasized that a cup of coffee contains 1g of dietary fiber, which is a strong sense of reasoning. There are many similar places. All in all, a very basic science book.
3. Gut by Giulia Enders
About the Book: After reading it during the Spring Festival, it subverted my imagination of the stomach a bit.
It turned out that my miscarriage and lack of breastfeeding would have an impact on my stomach and even my temperament.
Pay more attention to hygiene, separate raw and cooked food, supplement dietary fiber and probiotics, keep a happy and relaxed mood while eating, focus, and chew slowly, milk is not necessary for nutrition for adults, and saliva can relieve pain.
High-grade olive oil is extremely good to eat raw. Great advantage, high-temperature frying is very bad, leave 5 hours between meals, but drink water.
Soy products and cereals can help vegetarians. Yogurt that is rich in d-lactic acid is better. Antibiotics will kill all bacteria, including the good ones, so you need to supplement with probiotics in time.
You may not be able to go to the toilet for two days after diarrhea, the toilet is not a good way, and the eggs must be cooked. Don’t try raw food easily; there will be Toxoplasma gondii.
Don’t touch the cat easily. Dogs and their habitats: not too clean or dirty, do not bathe and wash hands too often, refrigerator temperature must be below 5 degrees.
pay attention to unsanitary food when traveling; dilution, drying, temperature, and cleaning. It's a great way to prevent harmful bacteria from multiplying.
Do not often pick your nose or touch your mouth or eyes with your hands, as it is easy for bacteria to invade. Healthy living depends on self-discipline.
4. Fiber Fueled by Dr. Will Bulsiewicz
About the Book: When it comes to fiber, it must be associated with the gut. Because the human body cannot digest fiber, it can only be broken down by intestinal bacteria.
The core of this is:
- Short-chain fatty acids - SCFAs (short-chain fatty acids) are the products of the decomposition of fibers by the beneficial intestinal flora, which have many benefits to the human body.
- prebiotics, probiotics, and postbiotics - that is, prebiotics, probiotics, and postbiotics.
- Rainbow Food Theory
- How to tell if the homemade sauerkraut is spoiled - just look at it with your eyes, if it is moldy, hairy, or smelly, it is broken.
5. Gut Garden by Katie Brosnan
About the Book: Within our bodies hides an entire world of organisms called microbes. They boost our immune systems, digest our food, regulate our metabolism, and even impact our mental health.
Through Katie Brosnan’s personable illustrations, we follow the digestive process from the moment the food enters our mouths to the moment waste leaves our bodies.
Along the way, we learn about this fascinating scientific frontier and gain an insight into the vast ecosystem that exists inside us.
6. 10% Human by Alanna Collen
About the Book: Understanding the 90% of Microbes That Govern Your Health and Happiness." The book points out that in addition to muscles and bones, bacteria and fungi make up our bodies.
These microbes are, to be precise, the main constituents of the human body, because 9 out of 10 cells that make up the body are free-living microbes.
There are as many as 100 trillion microbes that live in the gut, and they not only affect our health and weight but also control our brains and influence our choice of partners.
At the same time, studying them also provides new possibilities for overcoming the disease of modern civilization.
The author, Alanna Colman, is a master of biology from Imperial College London and a Ph.D. in evolutionary biology from University College London. She is a frequent contributor to The Sunday Times, The Guardian, and The Huffington Post.
At the age of 22, she was investigating bats in the Krau Wildlife Sanctuary in Peninsular Malaysia, and later became seriously ill with a tropical infection and received high-intensity antibiotic treatment.
After the infection recovered, her body developed some new symptoms. This sparked her research interest in the relationship between humans and microbes.
The whole book can be divided into three parts.
- The first part (Prelude - Chapter 3) details how microorganisms affect our physical health and control our brains.
- The second part (Chapter 4 - Chapter 5) details Understanding allergies because the immune system is too dutiful, and how people overuse antibiotics and destroy their own immune systems;
- Part 3 (Chapter 6 - Finale) We can be in harmony with the microbiome through conscious choices of food, medicine, birth, and feeding. Symbiosis, at the same time, can also reshape the microflora in the body and treat special diseases through "fecal transplantation" technology.
The process of reading this book is like rediscovering myself through a microscope. Analyze life's problems from a microbial perspective, and you'll see a whole new world.
7. The Good Gut by Justin and Erica Sonnenburg
About the Book: Sonnenburgs are at Stanford, and their talks are very informative, which prompted me to read this book.
Everything I read recently on a healthy plant-based diet comes together: symbiosis with a healthy microbiota fosters the metabolic elements, especially anti-inflammatory & endotoxin-reducing ones, necessary for a healthy life. Slightly repetitive.
There are three main problems. Before modernization, the human gut contained more than 1,700 kinds of bacteria, but now there are only more than 1,000 kinds of bacteria. These seeds can be used in wartime. The other is the culture medium in the intestinal tract.
These media can be summed up as eating coarse grains, which are conducive to rejuvenating energy and regulating the flora to produce substances that reduce weight, improve mood, and strengthen anti-inflammatory effects.
8. The Psychobiotic Revolution by Scott C. Anderson
About the Book: Written by the leading researchers in the field, this information-rich guide to improving your mood explains how gut health drives psychological well-being, and how depression and anxiety can be relieved by adjusting your intestinal bacteria.
This groundbreaking book explains the revolutionary new science of psychobiotics and the discovery that your brain health and state of mind are intimately connected to your microbiome, that four-pound population of microbes living inside your intestines.
Leading medical researchers John F. Cryan and Ted Dinan, working with veteran journalist Scott C. Anderson, explain how common mental health problems, particularly depression and anxiety, can be improved by caring for the intestinal microbiome.
Science is proving that a healthy gut means a healthy mind—and this book details the steps you can take to change your mood and improve your life by nurturing your microbiome.
9. The Gut Stuff by Lisa McFarlane
About the Book: Most people now know just how important the gut is to our health and well-being, including its impact on our digestive and immune systems and on diseases such as cancer, Alzheimer's, Parkinson's, and even mental health, but so much of the information out there is hard to understand or doesn't offer realistic solutions.
Alana and Lisa Macfarlane have spent the past few years interviewing top-notch gut pros: scientists, academics, chefs, and foodies to get the real scoop and science behind what we eat.
The book offers practical and achievable advice in a fun and accessible way and explains what gut health is and why it is so relevant today.
The science behind mind and body and how they are linked, including the gut's effect on sleep, anxiety, immunity, and skin, is covered, along with practical advice on what can be done to improve gut health.
10. The Doctor's Kitchen by Dr. Rupy Aujla
About the Book: Dr. Rupy Aujla’s first cookbook, The Doctor’s Kitchen, is the go-to book to help you kick unhealthy fad diets for good.
The book, Rupy, explains the principles of healthy living in a fun and relatable way with over 100 vibrant, tasty recipes steeped in medical science, which are easy and inexpensive to make.
The impact of lifestyle on illness has never been higher on the national agenda, and Rupy believes that what we choose to put on our plates is the most important health intervention we can make.
The Doctor’s Kitchen stands out from the crowd by using medical knowledge to create the recipes.
Rupy advocates Plates over Pills every time, and he is living proof that what you eat can shift medical outcomes, as he overhauled his own heart condition by addressing his diet and creating his own delicious food that he now shares in this book.
Infused with flavors from around the world, this tasty selection of everyday meals makes healthy eating an absolute pleasure.
11. The Microbiome Solution By Dr. Robynne Chutkan
About the Book: The microbiome—the collective name for the trillions of bacteria that live in our digestive tract—is today’s hottest medical news topic.
Dr. Robynne Chutkan explains how the standard Western diet and our super-sanitized lifestyle are starving our microbes, depleting the “good bugs” that are crucial for keeping us healthy, and encouraging the overgrowth of exactly the wrong types of bacteria.
But, as Dr. Chutkan explains, there are effective lifestyle and diet changes we can make to reverse this damage.
Dr. Chutkan has helped thousands of patients suffering from a disordered microbiome with her comprehensive Live Dirty Eat Clean Plan, designed to remove damaging medications and foods, replace important bacteria that have been lost, and restore health.
The MicrobiomeSolution offers:
A microbiome overview, nourishing recipes, questions for your doctor, preventative and recovery health tips, and the next frontier for a severely troubled microbiome—the stool transplant.
This is the first book to provide a practical, effective plan for replenishing and optimizing the vital ecosystem in our gut. Start living dirty and eating clean today to ward off disease and begin the path toward lifelong, vibrant health.
12. The Macrobiotic Path To Total Health By Michio Kushi And Alex Jack
About the Book: Even in medical schools, alternative medicine is blossoming. Two-thirds of them now offer courses in complementary healing practices, including nutrition.
At the heart of this revolution is macrobiotics, a simple, elegant, and delicious way of eating whose health benefits are being confirmed at an impressive rate by researchers around the world.
Macrobiotics is based on the laws of yin and yang—the complementary energies that flow throughout the universe and quicken every cell of our bodies and every morsel of the food we eat.
Michio Kushi and Alex Jack, distinguished educators of the macrobiotic way, believe that almost every human ailment, from the common cold to cancer,r can be helped, and often cured, by balancing the flow of energy (the ki) inside us.
The most effective way to do this is to eat the right foods, according to our individual day-to-day needs.
Now in this marvelous guide, they give us the basics of macrobiotic eating and living and explain how to use this powerful source of healing to become healthier and happier, to prevent or relieve more than two hundred ailments, conditions, or disorders—both physical and psychological.
This encyclopedic compendium of macrobiotic fundamentals, remedies, menus, and recipes takes into account the newest thinking and evolving practices within the macrobiotic community.
The authors integrate all the information into a remarkable A to Z guide to macrobiotic healing—from AIDS, allergies, and arthritis, to cancer, diabetes, and heart disease.
They also clearly explain what we need to know to start eating a true macrobiotic diet that will provide us with a complete balance of energy and nutrients.
Living as we all do in environmental and climatic circumstances that are largely outside our personal control, we must follow a healthy lifestyle, including a flexible diet that we can adjust to meet our own individual needs.
The Macrobiotic Path to Total Health gives us precisely the tools and the understanding we need to achieve this goal. Use it to build a strong, active body and a cheerful, resourceful mind.

14. The Mind-Gut Connection By Emeran Mayer
About the Book: The Second Brain: How gut-brain interactions affect our mood, decision-making, and overall health. Very interesting proposition, the study of intestinal flora is a popular research topic at present.
During my postgraduate period, I also conducted research on the relationship between intestinal flora and medicine enema for chronic kidney disease.
Although I have some understanding of the change and stability of the flora structure, the shock and novelty this book brought me were beyond my imagination.
The author is a very professional scientific researcher and a great storyteller. He combines these boring studies with our lives and uses the language of storytelling to bring readers into the book with questions.
However, if you're trying to read this book like a novel, you'd be wrong; it's a serious science book after all.
This book explains what we know but don't know why in terms of microbiota structure.
We ingest high-fat and high-sugar foods into the gut, stimulate the release of information from microorganisms, and transmit it from nerves to the brain to produce inflammation. This inflammation may not manifest at the time, but what about later?
He will develop various diseases, such as irritable bowel syndrome, encephalopathy, coronary heart disease, high blood pressure, etc.
As age grows, intestinal microorganisms gradually decrease, and Parkinson's syndrome also occurs in the elderly after the age of 60. This may be a new perception.
This book explains many phenomena from the perspective of the huge gut microbes that we are not familiar with, and also reveals another level of "people are different", and reminds readers of the dangers of the high-fat and high-sugar diet in North America and the benefits of the Mediterranean diet. Use interesting questions, explain boring scientific research in popular language, and then connect with our lives to provide healthy life guidance; this is the charm of this book.
But the only thing that makes the reading experience less enjoyable is that this book is more inclined to the form of a review. Although the author's story is good, it is still a bit cold as a scientific review.

16. Eat Dirt by Dr. Josh Axe
About the Book: In the past, my stomach often felt uncomfortable, and I would have abdominal distension and pain inexplicably. It can be said that it has troubled me all year round.
I also went to the hospital to see it, but nothing came out. It wasn't until I read the book "Eating Dirt" that I suddenly realized that I might be suffering from leaky gut syndrome. I will tell you the details below! Hope it helps those who have the same troubles as I.
To sum up, this book is: because of an unhealthy diet, excessive cleaning, living too conveniently, too much stress, and excessive medication, the microbes in our guts are disappearing, and the absence of important gut bacteria will produce a Leaky gut.
A leaky gut can cause allergies, obesity, depression, eczema, acne, and other symptoms that make people feel uncomfortable. To improve these conditions, we need to eat soil. How to eat? Did you pick up the soil directly from the ground and eat it?
Of course not, Dr. Josh Akers suggests we can: eat probiotic-rich foods like yogurt; get a dog and wash its dirty paws; swim in the ocean; stay grounded and barefoot on Grass, muddy paths, or concrete sidewalks after rain, etc.
Some may ask, What exactly is a leaky gut? What has it got to do with me? The so-called leaky gut syndrome can probably be understood by looking at the picture below. As for whether you have a leaky gut, and if so, how to improve it, this book will give you the answer.
