The text claims that breast milk is the only product that contains all substances necessary for life.

The evidence indicates that breast milk contains numerous essential nutrients, including carbohydrates, proteins, fats, vitamins, minerals, and immune factors, necessary for infant development and early survival. However, the claim that it is the only product with all substances necessary for life is misleading. Infant formulas can mimic many components of breast milk, although they are not identical. Breast milk is uniquely beneficial but not the sole life-sustaining nutritional source. No fact-check directly refutes or corroborates the claim outright, making it critical to rely on the available data from scientific sources.
