It is clear from the passage that the production and sale of artificial sweeteners----.
Artificial sweeteners permit people to keep their
sugar and energy intakes down, yet still enjoy the
delicious sweet tastes of their favourite foods and
beverages. The Food and Drug Administration
(FDA) has approved the use of four artificial
sweeteners - saccharin, aspartame, acesulfame
potassium (acesulfame-K) and sucralose. Two
others have petitioned the FDA and are awaiting
approval -alitame and cyclamate. Saccharin,
acesulfame-K and sucralose are not metabolised in
the body; they pass through the kidneys
unchanged. In contrast, the body digests aspartame
as a protein. In fact, aspartame is technically
classified as a nutritive sweetener because it yields
energy, but for all practical purposes, that energy is
negligible. Some consumers have challenged the
safety of using artificial sweeteners. Considering
that all compounds are toxic at some dose, it is
hardly surprising that large doses of artificial
sweeteners (or their components or metabolic byproducts)
have toxic effects. The question to ask is
whether their ingestion is safe for human beings in
quantities people normally use (and potentially
abuse). The answer is yes, except in the case of
aspartame, which may present a problem for
certain people and so carries a warning on its label.
