2. Not all preservatives are chemically made; there are also natural preservatives that are non-harmful such as sugar and salt. Such natural preservatives avoid the decomposition of food items.

3. Preservatives are heavily used in mass production like wheat, paddy, or other crops that are grown and stored in bulk. To avoid their decomposition, preservatives are added to serve billions of people.

4. Artificial preservatives act as antioxidants and make food acidic, reducing the moisture level in food items, and thereby slowing down the ripening process.

6. As the process of ripening is slowed down using preservatives, that means your trips to grocery stores would also be limited.

7. Preservatives are added to meats to remove all their toxins and make them safer for consumption.

Food preservatives are often linked with digestive disorders, nervous disorders, respiratory problems, and skin problems.

One should never ignore the harmful effects of artificial preservatives that they impose on human health. These are not related to adding up any nutritional value to the food, these are only meant to make food good in terms of shelf-life, appearance, and boost sales.
