The supermarket can paralyze your mind. Too many decisions come into play inside the corridors. Paper or plastic? Self checkout or ATM? Generic or no-frills brand name? Fresh or frozen? In this latest dilemma, fresh produce is apparently the safest bet, but don't thaw frozen fruits and vegetables just yet.

Studies conducted by IFR Extra have shown that produce can lose up to 45% of its essential nutrients during the journey from farm to fork, a period that can last up to 16 days. These berries, melons, tomatoes and vegetables can be exposed to pesticides, extreme heat and light during transport, further compromising their freshness and nutritional value.

By contrast, most frozen fruits and vegetables are quickly blanched, boiled, or steamed, then frozen within hours of being picked, a process that helps preserve both fresh flavor and nutritional value. Frozen products are also available throughout the year and, in most cases, are cheaper than fresh. It's about time, then, to stock your freezer with these underappreciated nutritional powerhouses.
