Rice (Oryza sativa) is one food grain which has been around for thousands of years. It is believed to have been cultivated about 5000-7000 years ago in Yangtze River Valley region of China and then believed to have been taken to Southeast Asia and Indian Subcontinent about 5000 years back. From the northern plains region, it was brought down to southern India about 3400 years ago.
In fact, India is one of the top producers of rice in the world in present times. The States of West Bengal, Andhra Pradesh, Uttar Pradesh are three highest producers of rice in the country. It is also the staple food item of eastern and southern parts of India.
Rice grows well in the hot and humid climatic regions of tropical latitudes which receive heavy rainfall (more than 100cm) or are well irrigated.
Archeologically, the earliest remains of rice grain in Indian subcontinent have been found in Indo-Gangetic plains region about 5000 years back.
A few varieties of Rice
1/7. The Brown Rice
Rice is brown due to the presence of husk. The husk comes with additional nutrient package as it contains fiber, vitamin, calcium and zinc. Therefore, nutrition-wise, brown rice is better that the white one.
2/7. The White Rice
White rice is a milled rice when husk, bran and germ is removed from the rice grain. It changes the flavour, texture and appearance of rice. This is less nutritious as compared to brown rice. However, it is good for storage and takes less time to cook.
3/7. The Black Rice
Black rice belongs to Oryza sativa L. variety of rice. It requires special soil conditions to grow black rice organically. The colour is due to the presence of a compound called anthocyanin.
It was known in China as a ‘Forbidden Rice’ since only the rich could afford it. In India, it is primarily grown and consumed in North-eastern parts (notably, Assam and Manipur) of the country. It is stickier than other varieties of rice due to presence of more amylose content.

Red rice is also a variety of rice, which is primarily grown in North-eastern parts of the country. Assamese red rice is quite popular. The germplasm of rice in Assam is quite rich and the soil and climatic conditions are suited to grow wide range of varieties, including the Red and the Black rice.
5/7. The Basmati Rice
Basmati Rice is a long, slender and aromatic rice which comes from the Indian subcontinent, with India accounting for a major share. Certain areas of India like Indo-Gangetic region of north-western region have Geographical Indicator tag for basmati rice.

4/7. Helps in Digestive System and Excretory System
Digestive and excretory system of human body is critical to good health. Since rice flour is rich in fiber, this helps in normal functioning in both these systems. The insoluble fibre content of the brown rice flour helps in regulating bowel movement, preventing cramps and treating diarrhoea. This fibre is not dissolved and provides the much needed lubrication to intestines digestion and for easing movement of excreta. This helps in improving colon health, preventing diverticulitis and reduces chances of suffering from haemorrhoids.

Its use as a thickening agent is also quite popular. It is used as a thickening agent in gravies, soups and sauces because of its ability to prevent liquid separation.

Drawbacks of Rice Flour
When compared with its main competitor, the whole wheat flour, rice flour has three drawbacks…
1/2. Contains less folate
Folate is important because it removes homocysteine from the blood. This reduces the risk of cardiovascular diseases. Women are advised to have more folate during pregnancy because it helps in development of new cells.

Another point of difference between whole wheat flour and rice flour is that the latter has fewer phytonutrients called lignans than the former. Lignans helps in fighting cancer, balance oestrogen levels, reduce chances of cardiovascular diseases and reduce the cholesterol levels.
3/3. Presence of Arsenic in Rice
Arsenic is present naturally in soils, rocks and water. Organic arsenic is present in plant and animal tissues. However, it is the inorganic arsenic which is more toxic and it is taken up by rice from polluted soil and water. Rice is known to accumulate more arsenic from soil and water than other food crops. Due to the fact that rice is grown in flooded or highly irrigated paddy fields which could have been polluted with arsenic.
Long term intake of arsenic causes a number of health issues, such as cancer, narrowing of blood vessels, hypertension, heart problems, neurological disorders and Type 2 diabetes.
This is particularly a big problem for those who intake rice because of its gluten-free content and for the kids who are given infant formulas, pudding or rice milk. Therefore, it is generally recommended not to give too much rice products to kids.
How to deal with the Arsenic problem?
If there is a fool proof way to determine that the lands from where the rice is coming is not contaminated with arsenic or is not polluted, nothing can be better than this. For this reason, many brands of rice have begun showing the area of their growth and some have even begun to label their rice packets with certification stamps.
However, in general, people can take following precautions while cooking to reduce the arsenic content in rice…
1. Brown rice generally has more arsenic than white rice. Therefore, if the intake has to be frequent, then white rice should be preferable to brown one.
2. Use the rice cultivated in the Himalayan region. Your local shopkeepers can tell the source of their procurement.
3. Always wash the rice before cooking. This remove about one-fourth of arsenic content. Make sure that the water used for cooking is not polluted with arsenic.
4. Even while cooking, it is suggested to use plenty of water.
5. Basmati and Jasmine rice varieties are better choices for cooking of rice.
6. If possible, you shall avoid rice which is grown in dry areas because these areas are irrigated and the water used for irrigation might itself be contaminated.
Can Rice Flour be made at Home?
Rice flour can be made at a flour mill close to your place or even at home (in case quantity is not large). You need to have the mill grinder at home to grind it. You will have to do it twice or three times.
