Many people use goji berries to treat eye, liver, and kidney ailments. Also known as wolfberries, these festive red berries have a sweet, slightly-sour taste and often come in dried form, like raisins.

Goji berries are a good source of vitamins and minerals, including:

• Vitamin C
• Fiber
• Iron
• Vitamin A
• Zinc
• Antioxidants

These berries contain all 8 essential amino acids. A single 4 ounce serving provides nearly 10 percent of your daily value for protein. For fruit, this is a surprising amount of protein.

The carbohydrates in goji berries are also complex carbs. This means your blood sugar will raise slowly, reducing your risk of a sugar crash afterwards.
