Either way for a long time goji berries were a staple in my bulk bin purchases and I'd throw them on my oatmeal pretty much daily. The biggest problem was cost, at least where I live goji berries in the dried state are really expensive. Over time I strayed and I pretty much only bought them when I saw them on sale.
I've learned that there really is no such thing as a super food. Real food, meaning fruits, vegetables, whole grains, beans, nuts, seeds, legumes are really all "super." There is no need to spend your way into the poor house chasing after the next big fad, and there will be another new fad just wait for it. Not that I don't get tempted by them anyway, just see my tart cherry juice experiment.
Now this all isn't to say goji berries aren't awesome. The thing is I love how they taste and nutritionally they are really a sound choice. The first thing that stands out is that they contain quite a lot of protein (and iron) for a fruit. Being a complex carbohydrate they don't spike your blood sugar and they are super high in fibre. The real superpower with this particular food is the high amount of vitamin A (180% of your daily required amount in 1/4 cup) which is a natural antioxidant. When eating iron rich plant foods you often want to pair it with vitamin C to help absorption and goji berries are high in vitamin C. You're also getting riboflavin, potassium, zinc, copper and selenium in reasonable amounts. Really this is a pretty super fruit. Just don't expect it to turn you into a superhero overnight, that might be asking a little much.
The biggest win for our home with goji berries was actually purchasing a bush and planting it in our front yard. I'm not a gardener. I pretty much kill anything as I have a bad habit of ignoring plants, forgetting to water them and just hoping they can self sustain. The fellow at the farmers market I purchased the bush from assured me that goji berries love bad soil and can be ignored. It turns out he was right and it thrives just fine despite my lack of green thumb. When I want berries I just pop out to the front yard and pull as many as I need for my oatmeal. It produces a lot of berries. When the first fruit crop died off last year we noticed that we had a second batch of fruit come along on the same bush. So if you want goji berries and are afraid of the cost like I was just plant one! The fresh fruit tastes slightly more bitter than the dried version and of course isn't chewy but rather soft like a grape tomato.
