Food preservatives which are used for food storage can cause serious threat to your health. You can have these problems due to preservatives.
You must have noticed “No added preservatives” written on most of the beverages which are stored or packed for consumables. But most of the beverages which are stored for longer duration for example tetra packs of fruit juices, chips, fries, etc have preservatives inside them to prevent them from getting spoiled. However these preservatives may increase the shelf life of the food product but it surely decreases your life or can surely have some adverse affect on your health. Let us know what are food preservatives and how do they affect your health.
What are Food Preservatives?
According to Nutritionist Ms. Sneha Gupta from City Hospital, Indore, food preservatives are substances which are added to the food items to help the food remain safe from bacteria growth. Most of the preservatives which are found in the food products have added chemical preservatives which contain sodium nitrate, sodium benzoate and propionate which are basically synthetic chemicals. These chemicals are quite dangerous to your health and can create many problems. Most of the junk food which is available in the market has added preservatives in them which are responsible for health problems. Also to add not all natural preservatives are beneficial for the body.
When the natural compositions of chemicals are not altered for putting it in food product, then it is called natural preservatives. Natural preservatives have anti-oxidants properties which help in keeping the food for longer duration cutting down the process of oxidisation and ageing. The natural preservatives which are used are salt and oil. If you know the process of making pickle, then you must be aware how salt and oil is used for preserving it and making the pickle.
Artificial or Chemical Preservatives
Most of the food which is stored for long time in containers and available in stores has been made a long while ago. But some preservatives are added to the food product to delay the contamination process. For example a fresh juice cannot be kept for long but the juice tetra packs available in the market have an expiry of 3-6 months. This is only possible due to addition of chemicals in the beverage which delays the oxidisation process of the food item and helps in preserving it. These chemicals are called additives.

Sodium Benzoate- To prevent bacterial growth in food items sodium benzoate is used. This may not be a dangerous additive for food but those are allergic or sensitive to benzoic acid may have similar issues to that of sulphites. These can include small risk of cancer, asthma, allergic reactions and leukemia. According to WHO, sodium benzoate can cause damage to heart, spleen, liver, kidneys and even brain due to excessive consumption.
