An article entitled "Changes to the Creole Menu" written by Carla Mndez Mart was recently published. It summarizes the new dietary guidelines issued by the United States Department of Agriculture and the Department of Health. These guidelines prohibit excess sugar and salt, suggest limiting fat intake, and increasing consumption of fruits and vegetables, fiber, and low-fat dairy products. It is also recommended to eat whole wheat and not white bread, and exercise regularly. The new guidelines attempt to tackle the increase in obesity in our population, including young adults and the elderly. Some researchers have associated a healthy diet with fewer health problems and greater longevity. Suppose that Puerto Ricans change our lifestyle and diet to follow the recommendations of the United States Department of Agriculture and the Department of Health. Under current accounting standards, how could the new lifestyle of Puerto Rican society affect the accounting of a defined benefit pension plan of a local company? Specifically, which components of pension expense could be affected?
