1. Boost Gut Health
The hours after 9 pm are crucial for the body’s detoxification process. Consuming probiotics through the habit of eating yogurt at night can regulate the gut environment, maintain a healthy balance of gut bacteria, and enhance toxin elimination.
Dr. Ji Yang Gao Sui, a Japanese digestive and liver specialist, recommends eating yogurt after dinner to support intestinal peristalsis. You will wake up the next morning with improved intestinal peristalsis.
2. Yogurt Prevents Obesity and Boosts Metabolism
According to Japanese weight loss expert Takafumi Kudo’s research, the intestine is most active from 10 pm to 2 am the next day.

3. Yogurt Provides Calcium and Maintains Bone Health
Professor Shigenobu Shibata, a nutrition expert, points out that calcium is a nutrient with a relatively low absorption rate.
Studies show that calcium absorption is higher at night, so many calcium supplements are recommended for evening use.
Yogurt is not just an excellent source of calcium but also contains fermented components such as lactic acid and acetic acid. These short-chain fatty acids create an acidic gut environment, increasing calcium absorption and reducing the risk of bone loss.
4. Yogurt Helps Maintain Muscle Mass and Prevents Muscle Loss
The human body recycles cellular nutrients through autophagy, a fundamental process of cell breakdown and regeneration.
If the amino acid supply is insufficient, muscle protein can be broken down for use. Consuming protein-rich foods like yogurt in the evening can help maintain muscle mass and reduce muscle loss.
5. Yogurt Provides Essential Nutrients for Body Recovery
Sleep is a crucial phase for the body’s recovery and cellular regeneration. If there is insufficient calcium in the blood, the body will release calcium from the bones to compensate.
Evening yogurt consumption provides necessary calcium and protein, promoting bone recovery and cellular metabolism.
6. Yogurt Improves Sleep Quality
Quality sleep is essential for the body’s recovery, but overeating at dinner can disrupt sleep quality.
It is advisable to reduce fat and carbohydrate intake at dinner. Yogurt, on the other hand, is a suitable evening snack as it is gentle on the stomach and intestines and does not significantly affect digestion or disrupt the body’s biological clock.
Additionally, yogurt is rich in tryptophan, a milk protein that promotes serotonin synthesis, contributing to improved sleep quality.
