Researchers reviewed 46 existing studies to understand how digital technologies are being used in food supply chains. They looked at tools like blockchain, Internet of Things sensors, and artificial intelligence. The goal was to see what impacts these technologies have on food safety, reducing food loss, and nutritional outcomes.
The review found that most studies focused on storage and transportation of food. Among studies that measured it, 89% reported positive impacts on food safety, and 83% reported positive impacts on reducing food loss. However, only 6.5% of the studies directly measured nutrition-related outcomes like whether people actually ate healthier food.
This creates an important gap in our knowledge. While digital tools seem helpful for keeping food safe and reducing waste between farms and stores, we don't have good evidence yet about whether they lead to better nutrition for people eating the food. The researchers note that the pathway from using technology in supply chains to actually improving people's nutrition remains largely unverified.
Readers should understand that this review shows promising early signs for food safety and waste reduction through technology, but we need more research specifically on nutritional outcomes. The findings don't prove that these technologies cause better nutrition, just that they're being studied for certain parts of the food system.
