Increasing evidence from animal, epidemiological and clinical investigations suggest that dietary anthocyanins/phenolic acids have potential to prevent chronic diseases, including cancers.
Anti- Pigmented rice has proved to have effect in weight reduction as it contains higher fiber and less digestible starch content, which assists to stop signals of hunger and discourage excessive consumption. Oxidative stress induced inflammation being key signal during obese condition and antioxidant rich pigmented rice has possible role in its alleviation.
Other general health benefits:
Nutritional psychiatry is a growing discipline that focuses on the use of food and supplements to provide these essential nutrients as part of an integrated or alternative treatment for mental health disorders. Pigmented rice being rich source of antioxidant cocktail, could play role in this which will be beneficial for future generations.
Consumption of pigmented rice can detoxify the body and purify the liver with the use of elevated antioxidant levels in the rice. The anti-oxidative status of blood, liver, and the aorta assessed resulted with less oxidative stress.
The dietary fiber per serving is remarkable in pigmented rice. Among which insoluble fiber enables to protect against constipation, bloating and other undesirable digestive symptoms. While soluble fiber like resistant starch act as prebiotic for healthy gut microbiome.
Black rice is broadly known as enriched rice and has been used in traditional medicine. Being gluten free, it is suitable for celiac patients also.
Boosts immunity, quench stress induced free radicals; High Iron(Fe) & Manganese(Mn) content.
Asians are known to have a genetic predisposition to poor insulin secretion by pancreatic Beta(β)-cells and their insulin secretion is prone to decline with Beta(β)-cell exhaustion.
Pigmented rice rich in spectrum of antioxidants like anthocyanins have thus been studied for its anti-diabetic effect using in vitro & in vivo models.
A significant reduction in glycosylated hemoglobin, fasting glucose, and improvements in serum insulin level has been observed in mice models treated with pigmented rice extracts.
Anthocyanins have deciphered to play pivotal role in regulating glucose uptake in the intestine and muscle via regulating the secretion of insulin from the pancreas through modulating glucose transporter (GLUT) receptors, thus bestowing the anti-diabetic effect.
Role of pigmented rice in regulating blood glucose homeostasis through inter-organ communication. Pancreas regulates glucose using insulin and glucagon in response to food intake. Further Insulin also acts on peripheral tissues (liver, adipose tissue and skeletal muscles) to increase glucose uptake, resulting in decreased blood glucose levels.
Anti-aging & managing glucose homeostasis
Red rice was characterized by a high quantity of oligomeric procyanidins (0.2 mg/g) with more than 60% of total phytochemicals found in the rice seeds. Procyanidins are high molecular weight polymers or complex flavan-3-ol polymers that consist mainly of catechin, epicatechin, gallocatechin, and epigallocatechin units that can also be found in rice germ and bran.
