Potent Antioxidants and Phytonutrients
Goji berries are renowned for their exceptional antioxidant content, which helps protect the body from damage caused by free radicals. These protective plant compounds, known as phytochemicals, are a primary reason for the berry's superfood status.
Zeaxanthin for Eye Health
One of the most notable antioxidants in goji berries is zeaxanthin, a carotenoid that gives the berries their bright red color. Goji berries are considered one of the richest dietary sources of this compound. Studies have shown that regular consumption can increase the density of macular pigment, which is crucial for protecting the eyes from age-related macular degeneration and blue light damage.
Goji Berry Polysaccharides (LBPs)
Lycium barbarum polysaccharides (LBPs) are complex carbohydrates unique to goji berries that make up a significant portion of their dry weight. These polysaccharides are linked to immune-modulating and anti-inflammatory effects. Animal studies and preliminary human research suggest they can enhance immune response and improve overall well-being.
Other Carotenoids and Flavonoids
Beyond zeaxanthin, goji berries contain other powerful antioxidants, including beta-carotene (a precursor to vitamin A) and various flavonoids. This broad spectrum of phytonutrients provides a comprehensive defense against oxidative stress throughout the body.
High Levels of Essential Vitamins
In addition to antioxidants, goji berries are loaded with several key vitamins vital for health.
Vitamin A
A small serving of dried goji berries provides a significant portion of the daily recommended intake of vitamin A, in the form of beta-carotene. Vitamin A is essential for vision, immune function, and skin health.
Vitamin C
Similar to other berries, goji berries are a good source of vitamin C. This vitamin is a powerful antioxidant that supports the immune system and plays a crucial role in collagen production, which benefits skin health.
B Vitamins
They also contain B vitamins like riboflavin (B2). B vitamins are important for energy production and cellular function, helping the body convert food into usable energy efficiently.
Abundant Minerals
Goji berries offer a profile of essential minerals that contribute to their health-boosting properties.
Iron
Often touted as a great vegetarian source of iron, a serving of goji berries can contribute significantly to your daily iron needs. Iron is a vital mineral needed for oxygen transport in the blood and red blood cell production.
Other Key Minerals
Other minerals found in these berries include potassium, which is important for fluid balance and blood pressure regulation, and smaller amounts of copper, selenium, and zinc, all of which play roles in immune health and other bodily functions.
Significant Protein and Dietary Fiber
Compared to most other fruits, goji berries stand out for their macronutrient profile, containing a notable amount of both protein and fiber.
Protein Content
For a fruit, goji berries are a surprisingly good source of protein, with a typical serving providing several grams. They also contain 18 different amino acids, including all essential ones. This makes them a more filling snack option compared to other dried fruits.
Dietary Fiber
The dietary fiber in goji berries aids digestion and promotes a feeling of fullness, which can be beneficial for weight management. Fiber is also important for maintaining a healthy gut microbiome.
How Goji Berries Compare to Other Fruits
To put their nutritional value into perspective, here is a comparison of 1 ounce (28g) of dried goji berries versus similar dried fruit options.
| Nutrient | Goji Berries (Dried) | Cranberries (Dried) | Raisins (Dried) |
|---|---|---|---|
| Antioxidants | Very High (Zeaxanthin) | High (Proanthocyanidins) | High (Phenolic compounds) |
| Protein | ~4 grams | ~0.1 grams | ~0.8 grams |
| Fiber | ~3.6 grams | ~2.5 grams | ~1.1 grams |
