Firstly, since your post is entitled "attack - goji berries", let me first mention that goji berries are no longer ok on atack, as they're considered a "tolerated item" (therefore on Cruise only if you're happy with your weight loss and not stalling etc, as they are carby).
Ref their health benefits, google tells us:
Over time, people have used goji berries to treat many common health problems like diabetes, high blood pressure, fever, and age-related eye problems. Goji berries are eaten raw, cooked, or dried (like raisins) and are used in herbal teas, juices, wines, and medicines. What Are the Benefits of Goji Berries?
Research shows that eating berries -- like blueberries, acai berries, cranberries, strawberries, and cherries -- offers some definite health benefits. Berries like the goji berry are filled with powerful antioxidants and other compounds that may help prevent cancer and other illnesses, including heart disease. Antioxidants may also boost the immune system and lower cholesterol. Eating foods high in antioxidants may slow the aging process as well. It does this by minimizing damage from free radicals that injure cells and damage DNA. When a cell's DNA changes, the cell grows abnormally. Antioxidants can take away the destructive power of free radicals. By doing so, antioxidants help reduce the risk of some serious diseases. Goji berries also have compounds rich in vitamin A that may have anti-aging benefits. These special compounds help boost immune function, protect vision, and may help prevent heart disease. Some research suggests that goji berry extracts may boost brain health and may protect against age-related diseases such as Alzheimer's. Other studies using goji berry juice founds benefits in mental well-being, and calmness, athletic performance, happiness, quality of sleep, and feelings of good health. These are preliminary studies that need to be repeated before definitive conclusions can be drawn. While goji berries are a rich source of antioxidants -- and early research shows a potentially powerful health benefit -- it's still unclear how they stack up against other berries. Researchers also don't know whether goji berry supplements have the same health benefits as the actual berries. Do Goji Berries Have Side Effects?
