Tag: Lactase production

Globally, approximately 65% of the human population has a reduced ability to digest lactose after infancy, a trait known as lactase non-persistence. This counters the common misconception that our bodies are designed to produce the digestive enzyme lactase continuously throughout our lives.

Worldwide, over 60% of adults are naturally lactase non-persistent, meaning their ability to digest lactose declines after childhood. For those who go vegan, this genetic trait is the primary factor, not the diet itself; vegans do not stop producing lactase due to their lifestyle.
