At the beginning of the 20th century, Paris, you would have fasted from midnight before receiving communion, and by mid century the fast requirements were lowered to a THREE hour fast (which my older sister can remember) and then to the ONE hour fast. Which, when you consider that communion in most Masses comes at about 35 to 45 minutes into the Mass itself, means that one refrains from food/drink for all of 15 to 25 minutes before Mass starts. Factor in the time it takes to actually GET to Mass (assuming one arrives on time); the requirement is really so little! I am glad that there is still some requirement, be it ever so small, that indicates both that we approach the Eucharist as a sacrifice (by making a small sacrifice ourselves) and also that the reception of Eucharist is that of Body and Blood, Soul and Divinity of our Lord Jesus Christ, real food and drink, that is hopefully seen as the special gift it is to us BECAUSE we choose to deny ourselves food and drink for a time before we receive.
And, of course, for those for whom even the one hour fast is a recognized health burden (such as a diabetic who cannot control when s/he might have a hypoglycemic attack), the requirement is abrogated. Likewise, a person who requires medication (esp. those who must take the medication with food, and at certain hours) may also take the medication and food, and still receive the Eucharist lawfully.
