Introduction: Why Gut Health Matters
Your gut is the foundation of your health—affecting digestion, immunity, mood, and metabolism. Yet, many people suffer from bloating, IBS, food intolerances, and leaky gut without realizing that the right foods can restore balance.
📌 Did You Know?
✔ Over 70% of the immune system is located in the gut.
✔ The gut produces 90% of serotonin (the mood-boosting neurotransmitter).
✔ Poor gut health leads to inflammation, brain fog, and weight gain.
💡 The good news? Functional Medicine uses specific superfoods to heal and strengthen gut health naturally.
