Excessive focus on sanitization and sedentary lifestyles have reduced our exposure to beneficial bacteria. Antibiotic misuse and Caesarean sections are the main culprits behind this decline. Antibiotics, effective against harmful bacteria, also eliminate beneficial ones. Consumption of these medications without a prescription disrupts the balance and diversity of the gut flora. During birth, infants acquire beneficial bacteria through the ingestion of fluids in the birth canal, initiating colonisation of their sterile gut. Cesarean sections hinder this, leading to a deficiency of vital gut flora. Fortunately, supplements and exposure to beneficial bacteria can address this imbalance.
