Human diet has changed throughout history. How has it changed?  In your opinion, has the change been good or bad?

Over centuries, people have shifted to quick-serve

food

because it can be served immediately and deliciously

instead

of waiting.

However

,

this

really changed their lifestyles and did more harm than good. Let us examine

this

in the following essay.

First

of all, for those who work, contemporary conveniences like the refrigerator, which keeps

food

fresh, or ready-made meals, which can be purchased frozen or canned from stores, are a wonderful lifesaver as all

that is

required is to open the can and eat.

Moreover

, short waves, which may readily penetrate

food

and cook or reheat

food

rapidly, are a feature of

this

technology.

However

, the more convenient, the more harmful they will get.  In spite of being a colossal advancement and being time and energy efficient, long-term studies and scientific evidence are not supporting

such

devices, and they are being blamed for at least minor risks if used on a long-term daily basis.

Additionally

, most processed foods are high in saturated fats and eventually lead to obesity. They cannot become substitutes for their diet, which is still not so easy to prepare due to the nature of its cooking methods.

For example

, some Vietnamese traditional foods are pretty hard to process.

However

, if they eat canned foods, they cannot have the original taste which may lead to excess nutrients. In conclusion, with the advancement of technology and lifestyle,

food

preparation has become much easier nowadays, and

this

has had both positive and negative effects on our lives. Every individual should consider wisely how to prepare their

food

to ensure good health.
