What is the evidence used by archaeologists to reconstruct dietary practices?

Archaeologists use a variety of evidence to reconstruct ancient dietary practices, including analyzing food residues on artifacts, studying animal bones found at sites, examining dental remains for signs of wear and tear, and conducting stable isotope analysis on human remains to determine the types of foods consumed. These methods provide valuable insights into the types of foods consumed, food preparation techniques, and the importance of various food sources in past societies.
