Shelf Life of Common Foods: Toss or Keep?
Are you sure of the grocery that you bought today will stay fresh and tasty for a week or so? Most foods bought at a grocery store do not come with expiration date and need to be checked for their freshness from time to time. It is a common misconception that if we store foods in the refrigerator, they might stay fresh and edible. It is imperative to keep a track of the time a food can be kept before it begins to deteriorate, or in some cases, become unsafe and less nutritious. Sure, all foods have a certain shelf life and cannot be kept beyond a certain period.

Our expert nutritionist, Dr. Shilpa Arora says, "every food has a shelf life and should not be consumed after the specified period. Considering the sources most foods come from nowadays, we must try to keep it simple and maintain a healthy and balanced life."



Here is a handy list of common foods and their shelf lives that will help you know how long foods remain fresh and nutritious and just how much you should stock them up:



1. Canned Foods



"When we talk about canned foods, you would know their shelf life generally extends to one or two years, which is only possible due to the preservatives added to them. They are high on sodium and sugar that keep them fresh for a long time, causing various health issues. Nowadays, we lead an unhealthy lifestyle and choose canned food over fresh, leading to high blood pressure, diabetes, depression and other health hazards. These foods are extremely dangerous in the long run and may have a negative impact on your life. Try and avoid canned foods as much as you can," insists Dr. Shilpa Arora. Once opened, you must remove the food from the can and place it in a sealed container in the refrigerator.
