Goji berries are a very good source of two key nutrients for eye health: zeaxanthin and lutein. Both of these carotenoid nutrients protect and repair the eye from damage, be it age-related or otherwise. Zeaxanthin and lutein help prevent macular degeneration, cataracts, and diabetic retinopathy. 
Research shows that a unique combination of polysaccharides found in goji berries may have protective effects against cardiovascular disease . Goji berries are also likely to exert their protective effects through the prevention of free radical damage and the oxidation of cholesterol because of their high levels of antioxidant carotenoids 
Again the unique polysaccharides found in goji berries come up in relation to immune health. Specific polysaccharides appear to both enhance white blood cell and spleen activity and reduce tumour formation through the activation of the immune system [4,5]. These polysaccharides have also been shown to induce cell death in prostate cancer cells .
The polysaccharides in goji berries may also help to normalize blood sugar levels. Studies show that these polysaccharides help to decrease elevated blood glucose and may reduce insulin resistance [7,8].
Brain & Memory
Goji berries may also help to protect the brain against damage and stimulate the growth of nerve cells, thus enhancing memory and cognition. Evidence supports these protective effects in drug-induced , stress-induced , or oxygen-deficit-induced (such as in sleep apnea)  brain damage. All these benefits will surely make you want to plow into this nutritious super fruit, and lucky you, I’ve got five recipes where goji berries shine. In addition to the following recipes, gojis can be easily thrown into smoothies, sprinkled onto salads, or even made into a tea (and make sure to eat the steeped berries after!). And for all the ribbing earlier, I do like goji berries just on their own, piled into the palm of my hand, and thrown into my mouth. I guess I like a sweetish horse-y taste after all. Here are the recipes:
