Final answer:
Delivery of cold food can reduce the efficiency of digestion because our body has to work harder to warm it up before it can be digested.
Step-by-step explanation:
Delivery of cold food can reduce the efficiency of digestion.
When we consume cold food, our body has to work harder to warm it up to body temperature before it can be properly digested.
This can result in slower digestion and decreased absorption of nutrients.
