Bird’s nest is a valuable nutritious health product, rich in protein, vitamins and minerals such as iron, zinc and phosphorus. Taking bird’s nest can improve human immunity and prolong life. Tumor patients are not unable to consume bird’s nest, because bird’s nest contains proteins that are not conducive to human absorption, and the nutritional value of bird’s nest is inferior to that of the high-quality protein foods consumed in daily life, such as eggs, milk and other proteins contained in bird’s nest that are utilized by the human body in a better way. The price of bird’s nest is much higher than normal food, so patients are advised to consume protein from daily food without the need to choose bird’s nest at a high price.
