    1. people’s desire for sweet and fatty tasting foods.
      • example
        • people’s desire for sweet and fatty tasting foods
        • In ancestral times,
          • sugar and fat typically signaled positive nutritional value (Ramirez, 1990).
          • Consequently, people’s sensory systems are designed
          • to detect the presence of sugar or fat in food,
          • and the brain’s gustatory centers produce desirable taste sensations
          • when those foods are consumed.
          • This would have served our ancestors well,
          • facilitating the choice of beneficial and nutritious foods.
        • in modern times
          • Many foods found in post-industrialized societies
          • contain processed sugars, hydrogenated oils, and other additives that enhance the taste of the food
          • without adding any nutritional benefits.
          • Foods laden with corn syrup, for example,
          • typically contain high numbers of calories
          • and their regular consumption can result in obesity, diabetes, and other problems.
        • Thus, the mismatch between
        • the features of ancestral versus modern foodstuffs
        • can lead adaptive sensory mechanisms
        • to produce maladaptive physiological consequences.
        • The desire for sweet and fat foods
        • promotes health problems,
        • even when this desire operates in a perfectly normal manner
        • and would produce health benefits
        • in the environment for which it was designed
