How Fermented Foods Keep the Liver and Intestines Young
1. Liver Detoxification
The liver is responsible for filtering toxins from the blood. With age, its efficiency naturally declines. Fermented foods help stimulate liver enzymes, making detoxification more effective.
📊 Statistics: A study published in the Journal of Nutrition found that regular consumption of fermented soy products reduced markers of liver stress in older adults by 32%.
2. Improved Digestion and Gut Health
A balanced gut microbiome means fewer digestive problems, less bloating, and stronger immunity. Probiotics in fermented foods increase good bacteria, which fight off harmful pathogens.
3. Reduced Inflammation
Chronic inflammation is one of the leading causes of aging. Fermented foods contain bioactive peptides that reduce inflammation, particularly in the digestive tract and liver.
4. Stronger Immunity
Since 70% of the immune system is located in the gut, having a healthy intestine strengthens the body’s natural defenses against disease.
Other Longevity Habits of the 95-Year-Old Doctor
While fermented foods are his “secret weapon,” the doctor also follows other principles of traditional Chinese medicine and lifestyle practices:
- Balanced Diet: Lots of vegetables, whole grains, and minimal processed foods.
- Herbal Teas: Daily consumption of green tea and chrysanthemum tea for liver cleansing.
- Daily Movement: Tai chi and light walking to keep blood flowing.
- Early Sleep: Going to bed before 10 PM to allow the liver to regenerate during its peak detox hours (11 PM – 3 AM).
- Stress Management: Meditation and breathing exercises.
These combined habits contribute to his remarkable vitality and sharpness at 95 years old.
