If a product has been irradiated, do I still need to wash it?
Yes, the FDA recommends washing bagged produce, unless the product has been pre-washed.
Does it taste any different?
Critics of irradiation argue the process takes a toll on the taste of fresh produce. Some blinded studies, however, have found that people can't tell the difference between the two, according to Bruhn.
Does the irradiation process result in a loss of vitamins and nutrients?
Yes, to a small extent. Studies have shown, for example, that vitamins A, C, and E are sensitive to radiation levels. However, the FDA says that the amount of vitamin loss from irradiation is insignificant in the context of a person's overall intake of vitamins. Other food preparation techniques, such as the boiling certain types of produce, can also reduce the number of vitamins available.
Does irradiated food cost more?
Yes, experts estimate that irradiated food will cost consumers a few extra cents at the supermarket.
