Goji berries
Goji berries, also known as wolfberries, are native to China and used in traditional medicine. They have recently become very popular in the Western world. One ounce (28 grams) of dried goji berries provides:
- Calories: 98
- Fiber: 3.6 grams
- Vitamin C: 15% of the DV
- Vitamin A: 42% of the DV
- Iron: 11% of the DV
Zeaxanthin and vitamin A, both of which are crucial for eye health, are also abundant in goji berries. Eating 14 grams of a proprietary milk-based goji berry formulation every day prevented age-related loss in eye health, according to a study of 150 older persons. Both this study and another comparable one suggested that consuming goji berries might increase blood zeaxanthin levels.
Goji berries contain antioxidant polyphenols, much like many other berries do. According to one study, healthy older Chinese people's blood antioxidant levels rose after consuming goji berry juice for 30 days. In another study, participants who drank goji berry juice for two weeks saw an improvement in metabolism and a reduction in waist size. These studies are encouraging, however, they are somewhat tiny. Therefore, more study is required.
