Chao says that different creatures make different modifications (such as glycation) to proteins after their production. Insects, which emerged about 300 million years ago, are more highly evolved than bacteria, which emerged several billion years ago, and are therefore closer to humans. They produce proteins that are higher quality, more active, and better suited to the needs of animals and people.
趙裕展指出，不同的生物在蛋白質產生後會做不同的修飾（即醣化），昆蟲在演化上屬於高等生物（約在 3 億年前），較數十億年前即已出現的細菌更接近人類，生產的蛋白質品質活性較高，也較符合動物及人類所需。
