“AMD affects your central field of vision and can affect your ability to read or recognise faces,” said Professor Glenn Yiu.
The researchers found that healthy participants aged 45 to 65 who consumed 28g of goji berries five times a week for 90 days increased the density of protective pigments in their eyes.
The pigments that increased in the group that ate goji berries, lutein and zeaxanthin, filtered out harmful blue light and provided antioxidant protection.
Both help to protect the eyes during ageing.
“Lutein and zeaxanthin are like sunscreen for your eyes,” said lead author Xiang Li. “The higher the lutein and zeaxanthin in your retina, the more protection you have.”
Known for their sweet, slightly sour flavour and vibrant red hue, goji berries have been used in traditional medicine for thousands of years to boost immunity.
Here are six health benefits of goji berries:
- Rich in nutrients: Goji berries are packed with essential nutrients, including vitamins A, C, and various B vitamins. They also contain minerals such as iron, zinc, and selenium, which are important for overall health and well-being.
- Antioxidant powerhouse: Goji berries are loaded with antioxidants, including zeaxanthin, lycopene, and beta-carotene. These compounds help protect the body against harmful free radicals, which can contribute to chronic diseases and aging.
- Supports immune function: The high vitamin C content in goji berries is known to support a healthy immune system. Adequate vitamin C intake may help reduce the severity and duration of common illnesses like the cold and flu.
- Eye health promotion: Goji berries contain high levels of antioxidants like zeaxanthin, which have been linked to promoting eye health. Zeaxanthin is known to accumulate in the retina and may help protect against age-related macular degeneration and other vision problems.
- Potential anti-aging effects: The powerful antioxidants present in goji berries may have anti-aging properties. They help neutralize free radicals, reduce oxidative stress, and promote healthy skin, potentially slowing down the aging process.
- Potential blood sugar regulation: Some studies suggest that goji berries may help regulate blood sugar levels. They may improve insulin sensitivity and glucose tolerance, making them a potentially beneficial food for individuals with diabetes or those at risk of developing the condition.
