A healthy eating, nutrition and exercise plan is something that has to be worked at constantly throughout a person’s life. As people age, nutrition needs will change. For instance, a young child needs the fat from whole milk for brain development and calcium to prevent bone deformities, but an older person is better off with milk that is one or two percent fat as the fat is no longer needed for brain development. Furthermore, while the calcium is still essential, it is not needed to protect against bone deformities, but to prevent osteoporosis. For these reasons milk can be part of a good diet throughout life. Alternatively, in the case of someone who has difficulty digesting the lactose enzyme in milk, either due to a lifelong issue with lactose intolerance or as a result of aging, it may become necessary to add supplements such as calcium pills fortified with vitamin D to obtain the health benefits that could otherwise be provided through the consumption of milk (Chapter 9, “Calcium is the Most Abundant Mineral in the Body,” 2006). Additionally, to ensure that a variety of vitamins are consumed, it is necessary to periodically review the diet to be certain that all vitamins are represented in the adequate amounts by the foods consumed on a regular basis. This is where a tool such as the SuperTracker, found on the United States Department of Agriculture website, is extraordinarily beneficial (United States Department of Agriculture, n.d.). The program provides information on how many calories people should ingest daily based on their level of activity as well as sections to record foods consumed, exercise routines, and notes on how moods affected or were affected by the foods consumed and physical activities performed. To reap the most benefits from this site, there are reports that can be generated that specifically indicate the exact types of fruits,
