What’s that on your pizza? You can bet it’s not just the extra cheese and onions you ordered.As a matter of fact, you can count on at least a dozen other extra additives that you never asked for.
【R1】____________ However, additives are nothing new, and neither is the controversy surrounding them.London in the 18th century could have been called the "adulterated food capital of the world", though it’s likely that other cities in other countries were just as guilty of the practice of food adulteration.One might think that food in the "old days" was pure and simple, but in many cases, what people paid for was not what they were getting.When black Indian tea became popular, it was common for manufacturers to buy up used tea leaves, which they stiffened with a gum solution and then tinted with lead, another dangerous substance.Practices like that eventually came to the public’s attention, and in 1860 the first British Food and Drug Act was passed.
【R2】__________ Salt has been used as a preservative for thousands of years, and, thanks to some basic and other quite complicated substances, we have "fresh" vegetables in January, and meat that doesn’t turn green on the way home from the grocery store.But as they say, there’s a price to pay for everything.
The federal government recognizes about 35 different categories of additives, which are used for various purposes.Antioxidants are added to oil-containing foods to prevent the oil from spoiling.Chelating agents stop food from discoloring.Emulsifiers keep oil and water mixed together.Flavor enhancers improve the natural flavor of food.Thickening agents absorb some of the water present in food and make food thicker.About 800 million pounds of additives are added to our food every year.
【R3】__________ The average American ingests about five pounds of food additives per year.The good news is that the majority of the hundreds of chemicals that are added to food are safe.In some cases, they’re even good for us, such as when vitamins are added.The bad news is that some of them are not safe, and these are the ones with which we need to concern ourselves.
【R4】__________ The sugar substitute aspartame is used in many diet beverages.However, some scientists believe that aspartame can cause problems with brain function and behavior changes in people who consume it.Aspartame is still widely added, although many lawsuits have been filed to block its use.
The additives sodium nitrite and sodium nitrate are two closely related chemicals to preserve meat.These additives keep meat’s red colour, enhance its flavour, and stop the growth of dangerous bacteria.Nitrate by itself is harmless, but it is quickly changed into nitrite by a chemical reaction that occurs at high temperatures.During this chemical reaction, nitrite combines with other chemicals to form some very powerful cancer-causing agents.
【R5】__________ But several additives, such as those we have mentioned, do pose some risks to the general public and should be avoided as much as possible.There is intense pressure on the federal government to ban unsafe substances.But it is also our responsibility as consumers to read labels and be aware of what we’re putting into our bodies, and to learn how to eat safe and healthy food for long and healthy lives.
A. What happens when we consume this conglomeration of chemicals?
B. It’s good to know that no signal food additive poses a severe danger to the entire population.
C. Despite the regulations on food purity that currently exist in almost every country, there are still problems.
D. Believe it or not, food adulteration is not all bad.
E. Today’s additives read like a chemistry book, so many people believe they’re a modern invention.
F. The first of the unsafe additives is artificial sweeteners.
G. Food additives make food more flavorful and easier to prepare; they make it last longer, look more appetizing, and feel better in our mouths.
