A jar of sauerkraut sits in warm sunlight, symbolising balance, patience, and natural wellness. Fermented foods have quietly returned from tradition to modern nutrition. They support digestion, boost immunity, and stabilise mood. For Pilates teachers and clients, they offer calm focus, sustained energy, and faster recovery. Fermentation happens when natural bacteria feed on the sugars in food. This process produces lactic acid, which preserves the food and creates probiotics.
