Check out this list of 5 side effects of food preservatives.
Food preservatives are essential for many reasons. They are used to maintain the consistency and texture of foods, improve or retain nutritional properties of the products, delay spoilage and increase shelf life, and enhance the flavours, textures, and colours of the foods. But how much do you really know about the side effects of these preservatives? In this article, Dr Eileen Canday, HOD, Nutrition and Dietetics, Sir H N Reliance Foundation Hospital, Mumbai, has shared some important facts about food preservatives and explained the various side effects associated with them.
Types of Food Preservatives
Not all food preservatives are bad or harmful though. One needs to learn how to differentiate the good ones from the unhealthy ones. There are two different types of preservatives:
Natural or class I preservatives
This category of preservatives includes salt, sugar, alcohol, vinegar, spices, syrup, edible oil, and honey. For generations, people have been using natural preservatives for homemade preserved pickles, papads, jams, etc.
Chemical or Class II Preservatives
To stop microbial growth and physical changes in colour, texture, and flavour that leads to deterioration in commercial foods, artificial preservatives like sorbates, nitrites, benzoates, sulfites, sodium or potassium nitrates, glycerides, glutamates, and others are used widely for longer shelf life.
