Topic: oral-sensory food properties

Nutrients and oral-sensory food qualities influence the subjective valuation of food. We recently showed that monkeys prefer sugar- and fat-rich foods, consistent with the integration of nutrient and oral-sensory properties into economic values to guide choice (Huang et al., 2021) and reinforcement learning (Huang & Grabenhorst, 2023).
