How is Black Rice Different From White Rice?

Health Benefits of Black Rice

Black rice is rich in dietary fibre, which has been linked to lower risks of heart disease, high blood pressure, stroke, and high blood sugar levels. 
• Reduces the risk of cancer: The antioxidants called anthocyanins found in black rice help protect the body from cell damage that can lead to cancer. Studies have shown that extracts from black rice can even fight cancer by stopping tumours from growing and spreading. Recent research suggests that anthocyanins may prevent cancer by reducing oxidative stress and causing malignant cells to self-destruct, a process known as apoptosis.
• Lowers the risk of liver diseases: Adding black rice to your diet can lower the risk factors for fatty liver disease. Its antioxidant properties can detoxify the liver and enhance its performance. Black rice boosts fatty acid metabolism as well as lowers the risk of high blood sugar and cholesterol levels, further reducing the risk of liver disease.
• Preserving brain functions: The antioxidants in anthocyanins found in black rice can enhance brain function, improving memory and lowering the risk of diseases like Alzheimer’s and dementia. Clinical studies have demonstrated that anthocyanins can enhance learning abilities and reduce symptoms of depression. 
• Prevents inflammation: Black rice has anti-inflammatory properties. It decreases reactive oxygen species and increases anti-inflammatory mediators like superoxide dismutase. This can help prevent inflammatory conditions such as allergies, joint pains atherosclerosis and dermatitis.
• Supports eye health: In addition to anthocyanins, black rice is rich in lutein and zeaxanthin, two carotenoids crucial for maintaining eye health. These antioxidants play a vital role in shielding eye cells and mitigating the impact of ultraviolet (UV) radiation.

Are There Any Cons?

Black rice, similar to other rice varieties, may contain traces of arsenic absorbed from the soil. To minimize your exposure to arsenic, rinse the dry rice thoroughly before cooking.
