A revolutionary method for reducing arsenic in rice: parboiling with recording (PBA)

A revolutionary method for reducing arsenic in rice: parboiling with recording (PBA)

arsenic in rice: a silent concern

rice, a staple that can be found in countless kitchens worldwide, has an unmentioned secret: arsenic. This naturally occurring element is available in the soil and in water, and rice plants have the remarkable ability to absorb and enrich arsenic, more than many other plants.

The long -term absorption of high arsenic can be serious health risks for humans:

carcinogenic effect

The International Agency for Cancer Research (IARC) classifies Arsen as carcinogenic in group 1, which means that there is sufficient evidence of a connection with the development of cancer. Cell damage caused by arsenic can cause mutations and lead to cancer in organs such as skin, lungs, bladder, kidney and liver. His genotoxic potential was demonstrated in various in-vivo and in-vitro studies.

skin problems

The skin, as a primary barrier and detoxification organ, shows signs of arsenic poisoning early. In chronic exposure, hyperkeratosis can occur, thickening of the skin, especially on the palms and soles of the feet. In addition, melanosis or the occurrence of dark spots can occur due to changed melanine formation or deposit.

cardiovascular diseases

arsenic can damage the function of endothelial cells in blood vessels and lead to functional disorders and lead to diseases such as hypertension and arteriosclerosis. Its potential for oxidative stress formation damages the blood vessels and increases the risk of different heart diseases.

diabetes

Studies have shown that arsenic can disturb the insulin signal path. This disorder of glucose absorption increases the risk of insulin resistance, a preliminary stage of type 2 diabetes.

neurological effects

arsenic has neurotoxic properties. It can affect the function of nerve cells and lead to peripheral neuropathy, which manifests itself in symptoms such as deafness in hands and feet. Cognitive impairments, including memory gaps and difficulties of concentration, were also associated with its neurotoxic effect.

respiratory diseases

Inhalative arsenic, especially from contaminated air or water vapor, can ignite the airways. Long -term exposure can lead to bronchitis, lung fibrosis and an increased risk of infections such as tuberculosis due to impaired lung function.

Immuntoxicity

arsenic can affect the immune system at cellular and humoral level. Its immunosuppressive effects lead to reduced production of important immune cells and antibodies, which makes the body more susceptible to a variety of infections.

The hidden compromise when removing arsenic

The culprit for the arsenic concentration is the outer spelze that surrounds the rice biscuits. Therefore, whole grain rice, which keeps this spel, contains higher arsenic values ​​than its sanded counterpart, white rice. Now one may think that the grinding process, through which brown rice becomes white rice, is the solution because it removes the spel and thus a significant proportion of the arsenic.

However, there is a catch: this process also removes 75-90% of the nutrients of the rice, which makes the polished grains less nutritious. Although earlier research has highlighted techniques such as cooking rice in excess water to reduce the arsenic content, this method has a disadvantage. The process that pulls out the arsenic also removes valuable nutrients and thus represents a nutritional dilemma.

A revolutionary cooking method for reducing the arsenic content

researchers from the Institute for Sustainable Nutrition have developed a user -friendly cooking method that significantly reduces the arsenic content in the rice, as a study published in the magazine Science of the Total Environment shows.

The newly developed cooking method, known as Parboiling with absorption (PBA) Method, offers a practical and user -friendly approach to reducing the arsenic content in rice. The PBA method includes the following steps:

1. rice to cook for five minutes
Drain
2. water and wash again with water
3. Cook the rice over low heat to absorb the whole water

This simple technology removes over 50% of the naturally occurring arsenic in brown rice and 74% in white rice and thus significantly reduces the risk of arsenic intake. It is important that the PBA method receives the essential micronutrients of the rice and thus ensures a nutritious meal.

The effectiveness of the PBA method when reducing the arsenic content in the rice without compromising the nutritional value was demonstrated by the researchers. The study showed no loss of micronutrients in both brown and white rice during the recommended, user -friendly cooking process.

The PBA method offers excellent news for rice consumers who are worried about arsenic recording. With this optimized cooking method, it is possible to significantly reduce the arsenic load, while at the same time the loss of important nutrients is minimized. You make the convenience and simplicity of the PBA method accessible to everyone.

Advantages of the parboiling with absorption (PBA) method

The PBA method not only significantly reduces the arsenic content in rice, but also offers other advantages:

preservation of essential nutrients

In contrast to traditional cooking methods that lead to a loss of nutrients, the PBA method receives the essential micronutrients of the travel, which makes them a healthier choice.

simple and practical

The PBA method is easy to use and does not require any special equipment. Everyone can use them in their own kitchen, which makes it accessible to everyone.

reduces the risk of arsenic recording

The use of the PBA method can minimize rice consumers, especially infants and children who are more susceptible to arsenic.

optimize your rice-dinner habits

Here are some practical tips to ensure that your rice dishes are not only delicious, but also health -promoting:

1. diversify your grain selection: While rice is a popular staple food, an occasional exchange for other grain such as quinoa, barley or bulgur can reduce your arsenic consumption overall and introduce a variety of nutrients.

2. Select the right rice: Geographical origin can affect the arsenic content. Basmati rice from India and Pakistan as well as Jasmin rice from Thailand generally have lower arsenic content compared to some types of rice from other parts of the world.

3. Adjust your cooking method: As the new research suggests, cooking of rice can be a groundbreaking change in a way that arsenic but receives nutrients. While the PBA method becomes more popular, the traditional approach in which excess water is used and then cast off can still reduce the arsenic content, albeit with a certain loss of nutrients.

4. moderate consumption: As with all foods, moderation is crucial here. Instead of eating rice every day, you can alternate with other side dishes to ensure a balanced diet and a lower arsenic load.

5. white rice instead of brown rice: While brown rice offers more fiber, it also has higher arsenic values ​​due to the spelage it contains. If arsenic is a problem in your region, you should eat brown rice with white rice
