Moreover, evidence suggests that these antioxidants may play a critical role in reducing the risk of age-related macular degeneration (AMD), a leading cause of vision loss globally. They may also lower the likelihood of developing cataracts and diabetic retinopathy, which are significant concerns for many.
Additionally, a one-week study involving mice revealed that the consumption of anthocyanin extract from black rice led to markedly reduced retinal damage when the subjects were exposed to fluorescent lighting. However, it is essential to note that similar studies in humans are still needed to confirm these findings.
In summary, black rice is a valuable source of antioxidants such as lutein and zeaxanthin, which are believed to safeguard your retina from potential damage caused by free radicals. While anthocyanins may also contribute to eye health, further research is required to better understand their effects in human subjects.
7. Naturally Gluten-Free
Gluten is a specific type of protein primarily found in cereal grains such as wheat, barley (??), and rye (???). For individuals diagnosed with celiac disease, it is essential to completely eliminate gluten from their diet, as its presence triggers an autoimmune response that can severely damage the small intestine. Beyond celiac disease, many people experience gastrointestinal distress, including symptoms like bloating and abdominal pain, when they consume gluten, a condition known as gluten sensitivity.
While a variety of whole grains typically contain gluten, black rice (???? ????) stands out as a nutritious and delicious option that is naturally gluten-free. This makes it an excellent alternative for those adhering to a gluten-free lifestyle, whether due to celiac disease or gluten sensitivity. Incorporating black rice into meals not only enhances flavor but also provides a wealth of nutrients.
