More Than Just Digestion: How Your Gut Bacteria Controls Inflammation, Obesity, and Aging

When you think of probiotics, you might first think of digestion, yogurt, or treating stomach aches. But according to Professor Tsai Ying-chieh, one of Asia's leading experts in probiotics and gut health, we have long underestimated the powerful role of the gut microbiome.
In a recent in-depth interview, the professor revealed that the bacteria in our gut act like a "second brain," having a tremendous impact on our overall health, from obesity and metabolic syndrome to mental health and aging.

At Anven Health, we have always upheld a science-backed approach to health. Today, let's delve deeper and help you understand why regulating your gut microbiome might be the missing key piece in your health puzzle.

1. The Root Cause of Obesity: Inflammation is the Culprit
For years, we've been told that the key to weight loss is "calories in versus calories out." However, the professor's research shows that there are more complex driving factors behind obesity: chronic inflammation.
* "Fat-promoting" bacteria: Studies show that the gut microbiome of obese individuals differs significantly from that of lean individuals. Even with the same diet, transplanting gut bacteria from obese individuals into mice leads to weight gain in the mice.
* The inflammatory cycle: When "harmful" bacteria (often fueled by high-fat, high-meat diets) overpopulate, they release toxins (such as LPS), triggering systemic inflammation. This inflammation disrupts metabolism, reduces insulin sensitivity, and causes the body to store fat—especially visceral fat in the abdomen.

Key point: You're not just feeding yourself, you're also feeding the bacteria in your gut. To fight obesity, you must fight gut inflammation.

2. The Gut-Brain Axis: Depression and Autism
One of the most groundbreaking areas in modern medicine is the study of "psychobiotics"—probiotics that affect the brain. Professor Cai explains that many neurological disorders, including depression, autism, and even Parkinson's disease, are linked to neuroinflammation in the gut. By repairing the gut lining and reducing inflammation, specific probiotic strains have shown the potential to improve mental health and cognitive function.

3. A Surprising Discovery: Probiotics and Anti-Aging
Perhaps the most surprising discovery from this interview was the connection between gut bacteria and mitochondria (the energy factories of our cells). Professor Cai's team found that specific probiotic strains can increase the number and quality of mitochondria in muscles. This leads to the following benefits:
* Improved athletic performance: enhanced muscle endurance and recovery.
* Anti-aging (probiotics for the elderly): In studies targeting elderly participants, specific probiotics improved their walking speed and muscle strength in just two months.This suggests that maintaining a healthy gut is crucial for preventing muscle atrophy that occurs with aging.

4. Expert Advice: How to Choose and Take Probiotics
With thousands of products on the market, how do you choose the right one? Here are some tips from Professor Cai for consumers:

Are fermented foods effective?
Not necessarily. While fermented foods (such as kimchi or sauerkraut) are beneficial to health, they don't always contain probiotics with therapeutic effects. To achieve specific health goals (such as reducing inflammation or anxiety), you need to choose specific strains that have been clinically studied.

Storage is crucial
* High temperature is the enemy of probiotics: Probiotics are very fragile. If you leave them in a hot car for two hours, they will die.
* Refrigeration principle: Always store probiotics in the refrigerator. Never freeze them (freezing and thawing will kill the bacteria).

Timing and regularity of consumption
* Timing: It doesn't matter whether you take them before or after meals; what matters is taking them regularly.
* Golden rule: You must take them every day and continue taking them long-term. Gut bacteria need time to colonize and change the gut microbiome. Don't expect miraculous results in a week.

Who should not take probiotics?
While probiotics are generally safe, people with serious acute illnesses (such as those undergoing chemotherapy or with severely compromised immune systems) should consult a doctor before taking high doses of probiotics.

The gut is the control center for inflammation levels in the body. Whether you want to lose weight, improve your mood, or stay vibrant as you age, your health journey begins with your gut microbiome.
