Numerous studies have demonstrated that our senses play a significant role in shaping food perception, eating experiences, and overall food consumption. As a result, multisensory stimuli are increasingly being used in food manufacture and product development. Building on this understanding, there is growing potential to explore a novel approach to healthy eating based on individual sensory responses. InstaFood is a speculative design project that envisions a future where dietary intake can be influenced through the manipulation of food-related visual cues. By combining insights from perceptual science, social media image analysis, and digital fabrication technologies, InstaFood proposes a new approach to personalized eating for well-being. This concept integrates digital technology, sensory perception, and healthy eating to offer an innovative framework for future dietary practices.
