Totally agree with Julia here. Food data is a nightmare to parse because people misremember what they ate or buy things for others. Imagine dedicating a whole team to track down whether someone actually bought those artisan cheeses when their phone GPS puts them miles away. That time could be spent pulling metadata from their social media or following money trails. Plus, food trends change so fast that what seems suspicious now might just be a diet fad. In the end, hard evidence like timestamps and transaction records don't lie, but grocery receipts often do.
