A cardiologist with 40 years of experience, Dr. Alok Chopra, shared insights on building immunity, emphasizing that it's a gradual daily process, not an instant fix. He highlighted the role of seasonal nutrition, particularly during winter, for maintaining warmth and digestion. Dr. Chopra recommended five immunity-boosting superfoods, including mustard greens (sarson) for its vitamins and fiber, and fresh turmeric for its antioxidant and anti-inflammatory properties. He also suggested incorporating cinnamon into daily routines.
