The Dark Side of Brown Rice: Cautionary Notes on its Usage

Brown rice, also known as whole grain rice, has gained popularity in recent years due to its perceived health benefits. However, the potential drawbacks of brown rice should not be overlooked or underestimated. Let's explore the downsides of brown rice with Mytour Blog right here.

What is Brown Rice?

Brown rice is a type of organic rice where the outer hull has been removed, leaving the nutritious bran layer surrounding the grain. This bran layer contains essential nutrients such as fiber, protein, and various vitamins and minerals.

• White Brown Rice: This type of brown rice has had the outer bran layer removed, leaving the inner white layer intact. White brown rice retains most of the nutrients compared to white rice, but has less fiber than other types of brown rice.
• Red Brown Rice: Red brown rice is a type of brown rice that is minimally processed, retaining the red bran layer. This type of rice has higher fiber content and often has a nutty flavor.
• Black Brown Rice: This rice has a dark black or purple outer layer. Black brown rice typically has higher antioxidant content compared to other rice varieties, has a distinct flavor, and is often used in desserts.
• Germinated Brown Rice or Sprouted Brown Rice: This is brown rice that has been germinated to stimulate sprouting. This process enhances nutrient levels, softens the rice grains, and makes them easier to digest.

Each type of brown rice has its own advantages and limitations, and the most suitable type for you may depend on your nutritional goals and personal taste preferences.

Benefits of Brown Rice – a Grain Dubbed as a “Superfood”

Brown rice is hailed as a superfood primarily because it is packed with nutrients and offers numerous health benefits.

• Richer in Nutrients:  Compared to white rice, brown rice retains the outer bran layer, containing more vitamins, minerals, fiber, and antioxidants.
• Efficient Weight Loss Support: Brown rice is particularly rich in fiber, which enhances satiety, slows down digestion, and reduces calorie absorption, aiding weight management.
• Enhanced Health Benefits: Brown rice also boasts high levels of Manganese and Selenium, playing crucial roles in antioxidant defense, immune support, improved bone health, and energy production.
• Promotes Brain Function: Additionally, brown rice is rich in B vitamins, essential for converting food into energy and supporting brain function.

Despite being considered a superfood, improper consumption of brown rice can lead to negative health impacts.

The Risks of Improper Brown Rice Usage

1. Arsenic in Brown Rice and the Risk of Cancer

Brown rice, like many other rice varieties, may contain Arsenic – a chemical element known for its toxicity. Arsenic exists in two forms: organic and inorganic, with inorganic Arsenic being the more toxic type. Arsenic can come into contact with rice through irrigation water and soil, so the level of Arsenic in rice can vary depending on the water source and farming practices.

According to the World Health Organization (WHO), long-term exposure to Arsenic can lead to serious health issues, including cancer. Inorganic Arsenic is classified as a carcinogen by the World Health Organization. Inorganic Arsenic can cause lung, skin, and kidney cancer.

Therefore, consumers need to be cautious when consuming brown rice and should limit the intake of large amounts of brown rice over an extended period to reduce exposure to Arsenic. Additionally, measures such as thorough rice washing and cooking rice with plenty of water should be implemented to reduce Arsenic levels.

2. Brown Rice and the Risk of Cross-Reactivity from Other Products

During the production process of brown rice, many rice manufacturers may use the same equipment for various products. This can lead to cross-reactivity, where allergens from one product may contaminate another product.

Brown rice is no exception to this. Products made from brown rice, such as rice cakes, rice flour, or snacks, may contain allergens from other products manufactured on the same production line. This is particularly important for individuals with allergies to certain types of foods.

To avoid this risk, consumers need to carefully read the information on product labels. If the product label indicates shared equipment with products you know you're allergic to, you should avoid that product. If you're unsure, consult with your doctor or nutritionist.

3. Brown Rice and Phytic Acid: Impact on Nutrient Absorption

Brown rice, like many other grains and seeds, contains phytic acid, an insoluble compound. Phytic acid can bind to certain essential nutrients in food such as iron, zinc, and calcium, inhibiting their absorption in the small intestine.

This means that although brown rice contains many nutrients, some of them may not be absorbed by the body due to phytic acid. This is especially important for individuals following a predominantly plant-based diet, where the main source of nutrients comes from grains and seeds.

Ways to Reduce Harmful Phytic Acid in Brown Rice: 

However, there are several methods that can help reduce the amount of phytic acid in brown rice and enhance nutrient absorption. One of these methods is soaking the rice before cooking. This method activates the phytase enzyme, which has the ability to break down phytic acid. Cooking rice with plenty of water can also help remove some phytic acid.

Groups Who Should Limit Brown Rice Consumption

• Pregnant Women: Brown rice may contain Arsenic, a harmful substance that could pose risks to fetal development. Therefore, pregnant women should reduce consumption of brown rice or even avoid it altogether.
• Individuals with Heart Disease: Some studies have indicated that Arsenic may have negative effects on heart health. Therefore, those with heart issues should consider when consuming brown rice.
• Elderly Individuals: Brown rice contains a lot of fiber, which can cause difficulties in digestion, especially for the elderly with weaker digestive systems.
• Children: Children need plenty of nutrients for growth. As brown rice contains phytic acid that may hinder the absorption of essential nutrients, it may not be suitable for children.
• Underweight Individuals: These individuals often require a calorie and protein-rich diet to boost health and immunity. While brown rice has fiber and nutrients, it may not provide enough energy for these individuals.
• People Recovering from Illness, Postpartum Women: During this period, the body needs to absorb many nutrients for recovery. Brown rice, with its ability to inhibit nutrient absorption due to phytic acid, may not be the best choice.

Safe and Healthy Ways to Use and Cook Brown Rice

After learning about the drawbacks of brown rice, it's important to know how to use it properly. Brown rice indeed offers many superior advantages over white rice. Specifically, the fiber and vitamin B content in brown rice are much higher than in white rice. Therefore, to use it safely, minimize its harmful effects, and maximize the absorption of nutrients from brown rice, you should note:

• Limit Brown Rice Consumption: You should restrict excessive consumption of brown rice as it may contain Arsenic if not properly processed and may cause indigestion due to its high fiber content.
• Soak and Rinse Brown Rice Before Cooking: This is a method to help remove some Arsenic and other unwanted substances that may be present in rice.
• Cook Rice with Plenty of Water: Cooking rice with plenty of water can help remove some phytic acid and Arsenic, reducing the risk of diarrhea and indigestion.
• Do Not Use Brown Rice as Sole Nutritional Source: Although brown rice has many health benefits, it should not be used as the sole nutritional source. Diversify your diet with other foods to provide adequate nutrition for the body.

Safe and Healthy Ways to Eat Brown Rice

• Eating Method: When eating brown rice, chew it thoroughly until the rice is completely softened in your mouth. This will help the digestive system digest and absorb nutrients from rice easily.
• Quantity: Although brown rice has many health benefits, you should not eat too much. Eat a moderate amount to ensure adequate energy and nutrient supply for the body without causing health issues. Specifically, you can alternate days of consuming brown rice and diversify other nutrient-rich foods such as sweet potatoes, oats, etc., to balance nutrient groups.
• Timing: You should eat brown rice at main meals of the day, such as lunch or breakfast, to provide enough energy for the body. Avoid feeling overly full in the evening when eating brown rice.

How to Store Brown Rice to Preserve Vitamin B1 Content

• Store rice in a dry, cool place: This helps prevent rice from becoming moldy and preserves the amount of vitamin B1.
• Avoid soaking rice for too long: Vitamin B1 is soluble in water, so if rice is soaked for too long, the amount of vitamin B1 may be lost.
• Cover the pot tightly when cooking rice: During cooking, if the pot is left uncovered, vitamin B1 may evaporate. Therefore, to retain the amount of vitamin B1, you should cover the pot tightly when cooking rice.

Brown rice, although considered a 'superfood' with many health benefits such as high fiber, vitamin B, and micronutrients, also needs to be used with caution.

Here are some drawbacks of brown rice that Mytour shares for those who use brown rice to carefully consider when adding it to their daily diet. You should also consult with a doctor or nutritionist about adding brown rice to your diet, especially if you have any existing health conditions.
