Essay On Food Preservatives
Conclusion
Figure 3 showed some common foods that are bought and eaten on a daily basis and the preservatives that are contained in these foods. This gives a clear indication of what people are eating and how many different types of preservatives they are consuming. Some of these basic foods contain up to three different types of chemical food preservatives, not just one! This shows that by consuming one of these food items, people are consuming three times the amount of chemical food preservatives.

Summary Of The Jungle By Upton Sinclair
1165 Words | 5 PagesMillions of people each day go to the store and purchase meat, produce, and medicine, without worrying if it’s safe, or whether it may be contaminated with things like paint stripper or cocaine.

Argumentative Essay On Nutrition Labels
