Tofu, Spirulina Seaweed & Fish-Head Soup

Why people make this soup

When you are pregnant, getting enough iodine matters — research has linked low iodine intake to impaired fetal brain development. Traditional Chinese food therapy has long turned to seaweed as a natural source of iodine, and spirulina seaweed in particular also brings calcium and folate into the pot. Paired with tofu for gentle, plant-based protein and a pan-seared fish head for sweetness and richness, this soup has been recommended in Cantonese households for generations to help nourish both mother and growing baby.
