BENEFITS OF BLACK RICE:

ANTIOXIDANTS: 

Black rice is rich in anti-oxidants. Importantly, it appears deep in colour. Antioxidants inhibit free radicals produced in the body. The free radicals are produced as a result of molecular metabolism. In addition, they also prevent cell damage. The compounds present in black rice such as amino acids, flavonoids inhibit free radicals reaction. 

The outer layer of rice made up of two layers bran and hull. The component called anthocyanin is present in abundance in black rice, brown rice, etc. This component acts as an antioxidant to prevent diseases like diabetes, cardiovascular disease, and even cancer. This component improves brain function as well. There is abundant vitamin E present in this rice which is very essential for our skin. Usually, all types of rice undergo a refining process where the outer layer gets milled off to produce rice. This rice doesn’t undergo any refining process and rich in nutrients.

RICH SOURCE OF FIBRE:

Firstly, roughage are nothing but dietry fibres. These substances break down carbohydrates, proteins, fats into simpler substances and improve our bowel movements. Improves digestion makes it an easier way.

Black rice is rich in 3 grams of fibre, this improves our bowel movements, breaks down the carbohydrates, proteins, and fats into simpler substances. This prevents constipation and aids in weight loss. Above all, this is a very good diet for weight loss.

DIABETES:

Diabetes is a metabolic disorder. To clarify, the blood glucose level is increased. There are two types of diabetes, diabetes mellitus type 1 and type 2.

It is higher in antioxidants than other types of rice. It has a low glycemic index (GI of 42.3) compared to white rice (GI of 55) and brown rice (GI of 50). This can reduce the blood glucose level. The fibre present in this rice absorbs glucose. This whole grain rice is a storehouse of fibre. This fibre takes a longer time to digest, the sugar present in this rice will maintain normal blood glucose levels. Studies have proven that it has shown very good results in type 2 diabetes patients. Adding black rice to diabetic patients’ diet consequently reduces diabetes.

WEIGHT LOSS:

More than two-thirds of the population is overweight. Staying fit is very important for us to maintain good health. Weight loss helps us to boosts our confidence level, improves our energy level.

Black rice is an excellent source of protein and fibre which aids in weight loss. Moreover, it reduces the appetite and has the feeling of fullness after consumption thus prevents overeating. In a recent study, they have found that in a group of people it showed excellent results for weight loss.

IMPROVES EYE HEALTH:

The components such as lutein and zeaxanthin present in black rice are rich in carotenoids. These carotenoids prevent macular damage that is eye damage. these are rich in vitamin A which supplies nutrients to the eye

GLUTEN-FREE RICE:

A gluten-free diet prevents vitamin deficiencies like vitamin B12, calcium, iron, zinc, vitamins like A, D, E, K. This type of diet also prevents celiac disease.

Celiac disease an autoimmune disorder, also called celiac sprue, non-tropical sprue, gluten sensitivity disease, it is characterized by diarrhoea, nausea, vomiting, fatigue, constipation, etc. Consumption of a gluten-free diet prevents celiac disease. Above all, black rice is naturally gluten-free rice, so people who are sensitive to gluten, suffering from celiac disease can add black rice to their daily diet.

FATTY LIVER :

Fatty liver also called hepatic steatosis, occurs due to the deposition of fat in the liver. On the other hand, occurs due to the consumption of a high-fat diet. Importantly, this black rice is an excellent liver detoxifier due to the presence of pigmented component anthocyanin in it. It has shown beneficial results in recent studies.

CARDIAC DISEASE:

Firstly, the risk of cardiac diseases increases when the arteries start building up lipids which lead to plaque accumulation. Moreover, the consumption of black rice prevents the deposition of lipids in the arteries and also prevents the risk of stroke, atherosclerosis, peripheral arterial disease, etc. Interestingly they have found that it prevents atherosclerosis in cardiac patients. Moreover, not only diabetic patients, but cardiac patients can also add black rice to their diet.

REDUCES BLOOD PRESSURE:

The fibre that we get from black rice, prevents heart disease, reduces blood pressure, prevents the accumulation of lipids, thus helps to manage hypertension. Besides, it regulates weight loss, maintains lipid level in the body.

REDUCES INFLAMMATION:

Inflammation is a sign of infection. To put in simple words, referred to as swelling or oedema. Most commonly oedema is a sign of kidney disease. In a recent study, they have found that black rice reduces inflammation. Moreover, they have found that its extract prevents chronic inflammation, cures various kinds of disease.

ANTI CANCER PROPERTY:

Similarly, it is rich in pigmented component anthocyanin, and in addition to its anti-inflammatory property, suppresses the undifferentiated tumour cell growth in cancer. Further, In recent research, they have found that black rice extract prevents cancer. However, this concept is under study.

IMPROVES BRAIN FUNCTION:

Firstly, oxidative stress occurs as a result of an imbalance between production and accumulation of oxygen reactive cells. Further, they have found that black rice reduces oxidative stress and improves our brain function. However, it also maintains oxygen levels in the brain.

ASTHMA:

Asthma also known as bronchitis is a respiratory condition that narrows the airway and causes inflammation. Importantly, the component anthocyanin is known to prevent asthma.

CONCLUSION:

To sum up, the pigmented component anthocyanin is deep black in colour, so it gives a purple hue. When soaked in water the colour of the rice changes to purple (hence the name purple rice). Further, various studies are being done about its beneficial effect in preventing various diseases. Currently, there are researches going on to study its benefits in treating Alzheimer’s disease. In addition, this forbidden rice can give us lead to a healthy lifestyle.
