Is White Rice Healthy? What Does Research Say About It?

Is white rice healthy? Are you concerned about the purported negative effects of white rice? Well, what if we told that white rice benefits you in multiple ways? Yes, you read it right. Over two thirds of people globally are estimated to consume white rice regularly (1). Japanese, the longest living people in the world, consume white rice as a major part of their diet (2). While white rice has received some flak, it also may benefit your health. Continue reading to know more about the benefits of white rice.

What Is White Rice?

White rice is nothing but milled rice with its husk, bran, and germ removed. This process alters the flavor and appearance of the rice, thereby extending its shelf life. After milling, the rice is usually polished, giving you the shiny and bright white rice that you see in the market.

The milling process cleans the rice and removes the husks off the grains, giving us brown rice. All the incredible brown rice health benefits that you hear about, comes from retaining the bran and germ, making it a rich source of fiber and essential nutrients (3). However, further polishing of brown rice removes these nutrients, resulting in white rice.

Without the bran and the germ, the grain loses 25% of its protein and 17 other key nutrients (4). The processors sure add the lost nutrients back to the refined grains. But, you will be consuming processed and refined rice.

Studies show that individuals who consume white rice at least five times a week are 20% more likely to develop type 2 diabetes (5). One major reason people prefer white rice is that it tastes good. White rice is also quicker to cook compared to other rice varieties (including brown rice).

Did You Know?

In Japan, white rice is not just a food item but also considered a symbol of purity and simplicity. It holds so much cultural significance that Japanese chefs take pride in the precision and artistry involved in cooking rice.

But, are these reasons justified? How bad is white rice really?

Why White Rice Is Possibly Bad

1. May Elevate Diabetes Risk

The biggest drawback of white rice could be the steep increase in the postprandial¹ blood glucose levels it causes (6). White rice also has a higher glycemic index (over 65), which can further increase diabetes risk.

Studies also show a 23% increased risk of diabetes with an additional serving of white rice every day. This is because the processing of white rice removes most of the fibers and nutrients from the grain that possess anti-diabetic properties (7).

The studies conclude that replacing white rice with whole grain carbohydrates (including brown rice) can be one of the strategies to cut diabetes risk.

This is the case not just with white rice. Consuming more of refined foods, including white bread and other sugary foods, can increase diabetes risk (8).

A prospective study was conducted with 132,373 individuals aged 35-70 years to study the association of white rice intake with incident diabetes. During the follow-up period, 6,129 individuals were diagnosed with incident diabetes. The study concluded that the intake of more than 450g/day of white rice led to incident diabetes.

2. May Cause Metabolic Syndrome2

A Korean study shows that individuals consuming white rice for longer periods could be at a higher risk of metabolic syndrome (9). This was particularly true in the case of post-menopausal women, where women who ate white rice were at a higher risk of metabolic syndrome than women consuming rice with multi-grains. Women who consumed white rice also showed signs of central obesity and dyslipidemia³.

In another Korean study, high consumption of white rice put adolescent girls at an increased risk of metabolic syndrome (10).

3. May Cause Weight Gain

Dietary patterns predominantly including white rice were shown to increase obesity rates (11). But, some studies could establish no significant link between white rice intake and obesity – and warranted further research (12).

However, white rice is a refined grain. Studies state that substituting refined grains with whole grains can promote healthy weight maintenance (13).

So, also consider white rice substitutes that provide more nutritional value and promote long-term health while making healthier food choices. Scroll down to know more. 

Alternatives To White Rice

If you want a healthy alternative to white rice, consider using brown rice, barley, or quinoa. Quinoa is high in fiber and antioxidants and provides all nine necessary amino acids, making it a complete protein. Soluble fiber, which is abundant in barley, promotes heart health and helps control blood sugar levels. When compared to white rice, brown rice has more vitamins and minerals, a greater fiber content, and is digested more slowly, which helps you feel fuller for longer. These whole-grain substitutes are great alternatives to white rice since they are lower in glycemic index, higher in nutrients, and offer longer-lasting energy.

These are the reasons you need to reduce your intake of white rice – if you are consuming too much of it already. But then, could white rice be good too? If yes, how?

How Can White Rice Be Good For You?

White rice can be easy on your stomach. This is probably the only way it can be good for anyone, especially in certain cases. Many cuisines around the world, especially those in Asia, the Middle East, and Latin America, place a high cultural significance on rice. Rice is often a staple item that serves as the basis for traditional meals in many areas. Rice can supply essential vitamins and minerals when consciously eaten as part of a balanced diet. By combining rice with veggies, lean meats, and healthy fats, you can make a complete meal that will benefit your general health without raising your blood sugar levels too much.

White rice is an important component of the BRAT diet, which consists of bananas, rice, applesauce, and toast. This diet is recommended following a stomach illness or diarrhea (14).

White rice plays an important role in treating diarrhea symptoms. It is low in fiber and helps in making the stool firmer (15). The low fiber content in white rice also means your stomach doesn’t have to do a lot of work to digest it if one has an upset stomach.

White rice is easier to digest. It can ease the uncomfortable symptoms of digestive issues like Crohn’s disease, inflammatory bowel disease, and ulcerative colitis. Being low in fiber, it reduces the load on the digestive tract and allows it to rest and recover.

Quick Tip

White rice mostly contains carbohydrates. Pairing it with protein-rich foods such as chicken, beans, or tofu, along with a mix of vegetables, not only enhances its taste but also adds a nutritional boost to your meal.

But, otherwise, brown rice is a great substitute for white rice. It is richer in fiber and other essential nutrients. The following table contains the average amount of nutrients each rice type offers for every 100 grams (3.5 ounces).

Brown rice has been found to fight inflammation as well. It was also found to lower blood pressure levels, as opposed to excess intake of white rice (16).

Long-term intake of brown rice was also associated with improved metabolic parameters and endothelial4 function (17).

An important point to be noted about brown rice is its arsenic content. Arsenic is a heavy metal naturally present in the environment, but it has been increasing due to rising pollution levels. Arsenic accumulates in the bran of the rice grain, which is what brown rice has (and white rice doesn’t). Excess intake of arsenic may cause cancer.

By excess, we mean several servings of brown rice every single day. If you make brown rice a moderate part of a varied diet, there is nothing to worry about! Remember – balance is key.

The simplest way to absorb all the goodness of white rice is to add them to your diet. Scroll down to find out how.

Now that you have a rice recipe to try, here are some practical tips to enhance your cooking technique and retain more nutrients while preparing white rice.

Practical Tips For Cooking White Rice

The following tips may help you enhance the texture and nutritional content of white rice:

• Rinsing the rice before cooking helps remove excess starch, preventing it from becoming too sticky and improving its texture.
• When cooking white rice, a typical ratio is one part rice to two parts water. Depending on the type of rice and the desired texture, slightly alter the proportion.
• When cooked, a pinch of salt improves the rice’s flavor without requiring additional fats or seasonings.
• Once you have the water boiling, lower the heat and cook the rice. This keeps more nutrients in the rice and helps it cook more evenly.
• Once the rice is cooked, remove it from the heat and let it rest, covered, for about 5 to10 minutes. This allows the rice to firm up and absorb any remaining moisture.
