Your “Second Brain”: Your gut is lined with nerve cells that talk directly to your brain. This connection (the gut-brain axis) heavily influences your mood, stress levels, and mental health.
Immunity Headquarters: About 70% of your immune system lives in your gut. A healthy gut lining and balanced bacteria help your body fight off infections and stay well.
The Nutrient Factory: Your gut bacteria help break down food, making it possible for your body to absorb essential vitamins and minerals that would otherwise go unused.
Hormone & Weight Control: The microbes in your gut produce chemicals and influence hormones that can affect how hungry you feel and how your body stores fat, impacting your weight.
A Defense Barrier: Your gut lining acts as a powerful barrier. When it’s healthy, it keeps toxins and bad bacteria _inside_ your gut; when it’s damaged (“leaky”), these things can sneak out and cause widespread inflammation.
