It is said that 100 trillion gut bacteria inhabit the human intestines. Recent surveys and research have elucidated the diverse types and functions of gut bacteria, revealing their close involvement in our health, such as 'bacteria abundant in long-lived people' and 'bacteria involved in mental condition.'
■ Gut Bacteria Deeply Involved in Physical and Mental Health
This book focuses on the functions of various gut bacteria, supervised by Dr. Jun Kunisawa, a leading authority in gut bacteria research.
Of particular note are the 'Five Major Gut Bacteria Common in Japanese People.'
It introduces five types of beneficial bacteria that are abundant in the intestines of Japanese people and are deeply related to health, explaining the characteristics of each bacterium and what kind of diet tends to increase which bacteria, based on extensive research findings.
It also unravels the fascinating relationship between gut bacteria and health, such as 'bacteria that make Japanese bodies less prone to gaining weight,' 'bacteria that break down excess cholesterol,' and and 'bacteria that improve endurance.'
＼You'll learn about this!／
◎ The relationship between the gut and mental health revealed by the latest research
◎ The mechanism of leaky gut and its impact on health and beauty
◎ How imbalances in the gut environment contribute to poor health and aging
◎ Japanese 'lean bacteria' and 'longevity bacteria'
■ New Common Sense for 'Gut Activity' You Can Start Today
To cultivate these beneficial bacteria and foster bacterial diversity, daily diet is crucial. It's important not only to consume fermented foods containing beneficial bacteria like lactic acid bacteria and bifidobacteria in yogurt and beverages, natto, and kimchi, but also to ingest dietary fiber, which serves as 'food for gut bacteria.'
This book introduces a comprehensive guide to gut health based on the latest science, from fiber-rich ingredients to notable yogurts and beverages containing lactic acid bacteria and bifidobacteria, and dietary methods that increase beneficial bacteria.
＼You'll learn about this!／
◎ Meat-eating, plant-eating, omnivorous - gut bacteria balance changes with eating habits
◎ What are 'short-chain fatty acids,' important substances for increasing good bacteria?
◎ Types and effects of bacteria contained in yogurt
◎ Dietary techniques and gut health recipes to foster gut bacteria diversity
