My mum brought home a bag of Goji Berries a few months ago, and I'd never heard of them. She explained she found them a the health food store, and had heard they were very good for health. They were around $12 for 113 g or 4 oz. On the package they claim to be "The Tibetan Superfood" and they are certified organic.
On the back it explains this:
"Of the many varieties of the botanical Lycium, Organic Goji berries considered to be the most health enhancing. It grows in profusion on vines that reach over & carotenoids, include beta-carotene. The berries are also rich in exces of 20 trace minerals such as zinc, iron, copper, phosphorus, as well as B complex vitams and vitamin E."
Per 28g, they have 90 calories, 0 g of fat, 4g of Fibre, 10mg of Sodium, and 12g of Sugars. They don't have any preservatives, the only ingredients are "organic Goji Berries"
so basically if I ate the whole bag, it would be under 400 calories. We still have the same bag my mum originally bought, so they are a little expensive, but last a long time. I eat a few berries a day, kind of like the amount of almonds they advise to eat a day. They don't have an expiration date, so they will last as long as you need.
I really enjoy the taste, it's like nothing I've ever had before. They start out crunchy like chips, and then get chewy. They are not overly sweet at all, but I can't relate the taste to anything.
I definitely say try them, I think they are great. I haven't noticed any health benefits, but they are getting a lot of hype.
hope that helps, sorry it's kind of long
