Goji berries may cost about twenty dollars per pound in natural foods stores, but they’re even cheaper than raisins in Asian supermarkets, where you can buy them as “Lycium” berries. I encourage you to swap out raisins for goji berries—in your breakfast oatmeal, as a snack, in muffins, and anywhere else. As one review concluded, goji berries offer a “‘whole food’ dietary supplement for the maintenance of retinal health as well as for prevention and/or delay in progression of retinal diseases commonly seen in clinical practice.
