Anwser this..?
You could start of with a general introduction and talk briefly about how what we eat and how it is produced has become a huge concern in recent years with the problems of obesity etc. Then say your essay is going to focus on one particular concern, which is chemicals in food. Then you could talk about when, what and why chemicals have started to be added to our food such as food colouring and various e numbers. These were considered safe, but things like Tartrazine have been found to cause hyper-activity. Many food additives have now ben banned or modified (colouring in Smarties)
The problem is the long term effects, and how they can affect us right down to genetic level. Chemicals have been tested and declared safe, but not in trials that last decades.
The long term future effects could be drastic, but we just don’t know. It’s a ticking bomb kind of thing.People have got used to cheaper food because of chemicals in the food business aid production - would people be prepared to pay more for cleaner food?
I hope that is in someway helpful.
