— Description —

Gut health is a topic we talk about a lot at ZOE. The gut doesn’t just fight disease, it boosts our mood, processes energy and so much more. Today’s bonus episode journeys through everything we’ve learnt about gut health so far. And what a myth-busting journey it is! In this episode, Jonathan delves into the microbiome, highlighting the most useful tips from conversations with ZOE’s U.S. Medical Director and resident gut health expert, Will Bulsiewicz, and Tim Spector, one of top 100 most cited scientists and author Food for Life.

Best of gut health - anniversary edition

Key Takeaways

  • Our guts play a crucial role in fighting disease, processing energy, and boosting our mood, largely due to the trillions of bacteria that make up the microbiome
  • The gut microbiome can be altered through diet, with an emphasis on increasing plant-based food consumption
  • Other factors such as sleep, exercise, emotional connection, and stress also affect the microbiome
  • Intermittent fasting has been shown to have positive effects on gut health, energy levels, mood, and weight loss
  • However, long-term use of proton pump inhibitors to treat heartburn can disrupt the balance of bacteria in the gut and increase the risk of infections
  • Gas, bloating, and constipation are common issues that can be managed through dietary and lifestyle changes, such as increasing fiber intake and reducing ultra-processed food consumption
  • Chronic digestive symptoms like gas, bloating, and constipation are cause for concern and should be addressed with a gastroenterologist
  • Regular and easy bowel movements are important for overall health, and improving gut health can lead to better bowel movements and overall health improvement
  • Ultimately, small changes in diet and lifestyle can have a significant impact on gut health and overall well-being

1. Exploring the Influence of Gut Microbiome on Mood, Weight, and Metabolism

  • Our guts help fight disease, process energy, and boost our mood
  • Trillions of bacteria live inside our guts and make up the microbiome
  • You could alter your microbiome through what you eat in just a few weeks
  • Gut microbiome affects health in an extremely powerful way
  • Studies indicate that gut bacteria are intertwined with our mood
  • Scientists started to observe and understand the gut microbiome in the last 20 years
  • One fascinating area of research is the interaction between gut microbiomes and our weight
  • Twin study demonstrated the difference in body habitus between identical twins, where one was obese and the other was skinny despite having the same genetic code
  • The gut microbiome is affected by what we eat
  • Increasing the consumption of plant food in our diet is important for gut health

2. Tips for Improving Gut Health through Diet, Fermented Foods, and Stress Management

  • Increasing the consumption of plant food in our diet is important for gut health
  • The average person in the US is only 10% plant-based, indicating room for improvement
  • Eat a wider variety of plants with every meal
  • Science is validating the benefits of fermented foods on gut health
  • Factors other than food affect the microbiome, such as sleep, exercise, time spent outdoors, and having pets at home
  • Partners who feel emotionally connected share more microbes together than those who feel distant and separated
  • During times of stress, the pituitary glands release a hormone called CRH, which can disturb the gut microbiome
  • Intermittent fasting, particularly time-restricted eating, extends the fasting time and limits eating to a set time window

3. Impact of Fasting and Microbes on Gut Health

  • Each time you eat, the brain sends signals to the gut, mobilizing an army of specialist microbes
  • Acomanthia comes out in force when the food-loving microbes disappear and feeds off the surface of the gut, which is free of food and other food-eating microbes
  • Intermittent fasting can lead to more energy, better mood, and weight loss for some people
  • Tim Spector, a leader in the field of gut health, has been studying the microbiome for 12 years
  • When fasting, a different set of bacteria appear in the gut as the bacteria replicate every hour or so

4. Understanding Heartburn, Acid Reflux, and Long-Term Medication Use

  • Positive changes to diet and lifestyle will help your microbiome thrive
  • Heartburn, also known as acid reflux, is a burning sensation in the chest caused by acid from the stomach
  • Heartburn occurs when acid from the stomach travels back up into the esophagus
  • Proton pump inhibitors like omeprazole, lansoprazole, or pantoprazole are commonly used to treat heartburn by blocking stomach acid secretion
  • Dependence on these medicines to suppress symptoms is concerning as we evolved to have stomach acid for a reason
  • Reduction of stomach acid can alter the balance of bacteria and increase the risk for infections
  • Long-term use of these medicines has been associated with infections such as Clostridioides difficile (C. diff)
  • Spicy or acidic foods like citrus and cooked tomatoes can irritate the esophagus and aggravate the symptoms
  • Fat intake from fried foods, meat, and full-fat dairy can slow down stomach emptying and worsen reflux
  • Sweet treats like chocolate or peppermint can relax the lower esophageal sphincter and potentially make symptoms worse
  • Ideally, it's recommended to go to sleep with an empty stomach, which means three or even four hours between dinner and bedtime
  • Gas and bloating are common issues, with studies estimating that one in six people experience these discomforts

5. Understanding and Managing Constipation, Gas, and Bloating

  • The first step is to prove that the person is actually retaining stool and backing up
  • There are many potential causes for constipation beyond just slow movement of the intestines
  • New testing has been developed that allows us to really get to the heart of understanding these problems
  • Studies estimate that one in six of us experience gas and bloating
  • Understanding the nuance is crucial for managing the bloating issue
  • There are four main causes of bloating: swallowed air, constipation, struggling gut microbiome, and food choices
  • Constipation is the number one cause of gas and bloating
  • Remedying constipation can offset some of the unpleasant side effects of bloating
  • The formal definition of constipation is having fewer than three bowel movements per week
  • A quarter of people worldwide have reported constipation symptoms
  • Gas and bloating is a telltale sign of constipation
  • Other symptoms include a distended belly, nausea, loss of appetite, and fullness after meals
  • Crampy abdominal pain and discomfort can come in waves and be extremely intense
  • Fatigue can be another common symptom of constipation

6. Natural Approaches to Treating Constipation and Improving Diet

  • Start with diet and lifestyle first when treating constipation
  • Increasing intake of whole plant foods can increase fiber intake
  • Reducing ultra-processed food intake leads to a more microbiome-friendly diet
  • It can improve the health of bowel movements and potentially resolve mild constipation
  • ZOE program members reported significant reduction in constipation after reducing ultra processed food intake
  • The Zoe program was developed using the microbiome and looking at things like blood sugar, blood fat, attempting to improve the health of the microbiome

7. Recognizing Signs of Unhealthy Gut and Digestive Symptoms

  • Improving gut health can lead to better bowel movements, improved digestive health, and reduced constipation
  • Gas, bloating, heartburn, and constipation are clear signs that something's wrong with gut health
  • Chronic symptoms occurring weekly or more frequently are a cause for concern
  • Classic digestive symptoms include gas, bloating, constipation
  • Asking about bowel movements is incredibly important for a gastroenterologist

8. Importance of Bowel Movements, Gut Transit Time, and Overall Health Empowerment

  • Bowel movements are considered a vital sign in gastroenterology
  • Regular and easy bowel movements are important for overall health and well-being
  • Gut transit time is a better measure of gut health than stool consistency or frequency
  • Eating a varied diet high in fiber can improve gut health
  • Improving gut health can lead to better bowel movements and overall health improvement
  • You have the power to make small changes that can yield massive results in your health
