Are frozen, canned, and jarred vegetables good choices?
Fresh is generally best for maximum nutrition. However, vegetables are usually frozen soon after they’ve been picked, so their nutrients are well preserved. Canned vegetables lose some of their water-soluble nutrients, may be high in added sodium (unless no- or low-sodium options are chosen), and are often packed in cans with liners containing bisphenol A (BPA), a chemical found in hard plastic that’s been linked to a variety of health problems. Choose BPA-free cans or glass jars.
