For the first and second meal session, the meals will contain foods that are categorized into two food shapes (Regular and Irregular) and two food complexities (Single food and Mixed food). Each meal will contain four foods with the four foods representing the four potential food categories (regular-shaped single food, irregular-shaped single food, regular-shaped mixed food, irregular-shaped mixed food). Along with the four foods, participants will be given 20oz of water in each meal session. Foods will be weighed prior to being provided to participants and the amount provided to participants will be within +/- 3g of the amount calculated. Mixed foods will be broken down into their individual food components and measured. Each meal will provide approximately 50% of daily estimated energy need for each sex. The Estimated Calories Needed Per Day for males and females aged 19 to 35 years are 2450 kcal/day and 1900 kcal/day, respectively. Thus, each meal will provide approximately 1225 kcal for males and 950 kcal for females. Each food will provide approximately 25% of the energy for each meal.
