Viruses are at the heart of this century-old debate. Viruses<span> are parasites that infect plants, animals, fungi and bacteria. They consist of genetic material surrounded by a protein coat and are unable to grow or reproduce without a host. The classification of viruses has confused scientists for nearly 100 years. Originally they were viewed as poisons. In fact, the word ''virus'' is Latin for ''poison.'' They have since been viewed as living creatures, then mere bio-chemical compounds, and, most recently, somewhere in between chemical compounds and lifeforms.</span>Non-cellular life<span> refers to organisms, such as viruses, that exist without any cells, and it is a very controversial topic. The cell theory, which is one of the fundamental tenets of biology, states that all living things are composed of cells and that cells are the basic units of life. So the idea that something can be considered alive without having cells is an issue that is up for debate.

The body does not require any added sugar to stay healthy. Hunters/gatherers and our ancestors consumed fruits and milk that are natural sugar to obtain energy.
<h3>What is the difference between added sugar and natural sugar?</h3>
- Natural sugars are found in unprocessed food such as fruits and milk.
- Fruits contain fructose and milk contains lactose.
- On the other hand, added sugars are the artificial sweeteners that we often add to our daily diet in the form of white sugars and caloric sweeteners.
- From the perspective of health, it is always better to opt for natural sugar that keeps our body stable energy and stable metabolism.
- Added sugars are harmful when consumed in higher quantities.
Hence, added sugar is not necessary for our health when we have learned that aerobic cellular respiration uses glucose as a fuel source that can be obtained from natural sugar.
