Preferences in food can greatly affect the increase or decrease in the consumption of a particular food. Let's take for example, watermelon which is consumed by some persons because of its healthy nutrient, may not be consumed by someone who likes sweet food and does not consider it sweet enough for his or her taste.
Forcing a person to eat a particular food because it contains healthy nutrients that the person really needs may not be a good idea.
The person may only eat it for one or two days and stop eating it because he or she does not like the taste and the person may end up vomiting in the process.
It is therefore important to give the person other food that the person likes which contains the nutrients that he or she really needs.
If the person is supposed to consume watermelon because it contains vitamin c which the person really needs to have a healthy growth and does not like it (watermelon) he or she can also be given other food that he or she likes which contains vitamin C.
Every one has different preferences when it comes to food. What are yours?
