Does rice flour affect blood sugar levels? Explaining GI and health benefits
The GI of rice flour and its effect on blood sugar levels
What is GI?
GI (glycemic index) is an index that shows the degree to which a food raises blood sugar levels. GI is expressed relative to the degree to which each food raises blood sugar levels, with glucose as the standard (GI value = 100). The lower the GI of a food, the more gradual the rise in blood sugar levels, while foods with a high GI tend to raise blood sugar levels more rapidly. Generally, foods with a GI of 55 or less are classified as low GI foods, those with a GI of 56-69 as medium GI foods, and those with a GI of 70 or more as high GI foods.
GI characteristics of rice flour
Rice flour is known to have a lower GI than wheat flour. The GI value of rice flour is estimated to be around 50-60, which puts it in the category of low to medium GI foods. This value is clearly lower than polished rice (GI value: around 73), and it is expected to have the effect of suppressing the rise in blood sugar levels. Starch, the main component of rice flour, is composed of amylose and amylopectin. The starch contained in rice flour has a relatively high amylose content, and it is thought that this amylose has the function of slowing down digestion and absorption.
Why rice flour slows down the rise in blood sugar levels
There are three main reasons why rice flour slows the rise in blood sugar levels:
- High amylose content
- Rich in dietary fiber
- Slow digestion and absorption
First, the high amylose content of the starch contained in rice flour is a major factor in suppressing the rise in blood sugar levels. Amylose has a linear structure and takes time to be broken down by digestive enzymes, which slows down the absorption of carbohydrates. Second, rice flour is rich in dietary fiber. Dietary fiber slows the absorption of carbohydrates in the small intestine, preventing a sudden rise in blood sugar levels.
The insoluble and soluble dietary fiber contained in rice flour helps to moderate the rise in blood sugar levels. Furthermore, rice flour is characterized by a slower rate of digestion and absorption than wheat flour. The starch granules in rice flour are larger than those in wheat flour, and take longer to be broken down by digestive enzymes. This difference in digestion and absorption rate contributes to the effect of suppressing a sudden rise in blood sugar levels.
Differences in GI depending on the type of rice flour
There are various types of rice flour, such as white rice flour made from polished rice, brown rice flour made from brown rice, and glutinous rice flour made from glutinous rice.The GI values of these rice flours vary depending on the type of rice used as the raw material and the manufacturing method.
[ Types of rice flour and GI values
| Symptom types | Specific symptoms |
|---|---|
| digestive system | Diarrhea, constipation, abdominal pain, abdominal distension, vomiting, etc. |
| skin | Eczema, rash, itching, etc. |
| Mental and nervous system | Headaches, depression, irritability, difficulty concentrating, etc. |
| whole body | Fatigue, weight loss, anemia, osteoporosis, etc. |
Brown rice flour tends to have a lower GI than white rice flour, which is made from polished rice. This is because brown rice flour contains the outer layer and germ of brown rice, making it rich in dietary fiber, vitamins, and minerals. On the other hand, glutinous rice flour has a slightly higher GI than white rice flour or brown rice flour. This is because glutinous rice starch has a very high amylopectin content and a low amylose content. Amylopectin has a branched structure and is easily broken down by digestive enzymes, so glutinous rice flour tends to raise blood sugar levels more easily than other rice flours.
Health benefits and precautions of rice flour
Health benefits of stable blood sugar levels
Rice flour has a lower glycemic index (GI) than wheat flour, which helps to moderate the rise in blood sugar levels. Stabilizing blood sugar levels provides a sustained supply of energy over a long period of time, helping to regulate the body.
Rapid fluctuations in blood sugar levels can also stimulate insulin secretion, leading to fat accumulation, but consuming rice flour can help alleviate this problem. Furthermore, stable blood sugar levels contribute to maintaining concentration and memory, as well as relaxing the mind and body. Therefore, incorporating rice flour into your daily diet can be said to have great benefits for living a healthy lifestyle.
Improves intestinal environment and reduces allergy risk
Rice flour is rich in dietary fiber, which helps regulate the intestinal environment and promotes the growth of beneficial bacteria. Increasing beneficial bacteria reduces harmful substances in the intestines, leading to improved immunity and healthy skin.
Additionally, rice flour does not contain gluten, so it can be safely consumed by people with wheat allergies or gluten intolerances. Dishes and sweets made with rice flour are an excellent option for enjoying a diverse diet while reducing the risk of allergies. However, some rice flour products may contain ingredients that are allergens, so it is important to carefully check the ingredient label when purchasing.
The health risks of high sugar
While rice flour has health benefits, it is important to note that it is high in carbohydrates. Excessive consumption of rice flour can lead to excess calories and increase the risk of obesity and metabolic syndrome. Additionally, sweets and bread made with rice flour, like wheat flour products, can contain a lot of sugar and fats. Therefore, care must be taken when selecting rice flour foods, and it is important to maintain a balanced diet.
Harmful effects of sudden fluctuations in blood sugar levels
Although rice flour is a low GI food, eating large amounts at once can cause a sudden rise in blood sugar levels. A sudden rise in blood sugar levels stimulates insulin secretion, making it easier for energy to be stored as fat. Rapid fluctuations in blood sugar levels also put a great deal of stress on the body, which can lead to symptoms such as fatigue, irritability, and decreased concentration. Therefore, when eating rice flour foods, it is important to eat them in moderation and combine them in balance with other foods.
Risk of fat accumulation due to excessive intake
Rice flour is not lower in calories than wheat flour. Consuming too many dishes and sweets made with rice flour can lead to excess calories and make it easier for fat to accumulate. In particular, sweets and bread made with rice flour can contain a lot of sugar and fats, making them high in energy density. Therefore, when eating rice flour foods, it is important to limit the amount consumed and snack less frequently. It is also important to incorporate regular exercise into your daily routine to maintain a healthy energy balance.
How to consume rice flour while considering nutritional balance
To incorporate rice flour into your diet in a healthy way, it's important to consider nutritional balance. Rather than relying solely on rice flour, it's important to properly combine it with other grains, vegetables, and protein sources. Also, when choosing dishes or sweets that use rice flour, be sure to pay attention to the amount of carbohydrates and fat, and choose ones made with as few ingredients as possible.
Furthermore, eating dishes made with rice flour together with fiber-rich vegetables, seaweed, mushrooms, etc. will improve the nutritional balance. When incorporating rice flour into your diet, it is important to take the appropriate amount based on your health condition and constitution. We also recommend incorporating rice flour into your diet within reasonable limits, consulting with a doctor or nutritionist.

Points to consider when choosing rice flour products
Check ingredients labeling
When choosing rice flour products, it is important to carefully check the ingredient label. Rice flour is primarily made from rice, but the taste and nutritional value of the product vary depending on the type and quality of the rice. By looking at the ingredient label, you can find out the type of rice used, its origin, and the manufacturing method. Rice flour products may also contain a variety of ingredients other than rice flour. For example, they may contain secondary ingredients such as baking powder, oils and fats, and sugar.
These ingredients affect the taste, texture, and expiration date of the product, so it is important to check the ingredient label. You can also check the ingredient label to see if it contains any allergens. Some rice flour products are safe for people with wheat allergies or gluten intolerances, but there is a possibility that allergens may have been mixed in due to shared production lines. Checking the ingredient label will help you choose the rice flour product that is right for you.
Restrictions on additives and processed foods
When choosing rice flour products, it is important to check the additives and processed ingredients used. Rice flour products may contain additives such as preservatives, coloring agents, and thickeners. These additives are sometimes used to improve the quality and safety of the product, but excessive consumption may have adverse effects on health. Rice flour products may also contain processed ingredients such as sugar and fats and oils.
These processed foods are used to improve the taste and texture of products, but excessive consumption can lead to excess calories and nutritional imbalances. You can check the use of additives and processed foods on the ingredient and nutritional information labels. Choosing products that use as few additives and processed foods as possible will allow you to consume healthier rice flour products. However, not all additives and processed foods are bad. Using them to a minimum can improve the quality and safety of the product. It is important to choose the right rice flour product based on your health condition and preferences.
Selecting a reliable manufacturer or retailer
When choosing rice flour products, it is important to choose a trustworthy manufacturer or retailer. Trustworthy manufacturers and retailers focus on quality control and hygiene management, and provide safe, high-quality products. They are also highly transparent about how they source ingredients and the manufacturing process, providing sufficient information to consumers. When choosing a trustworthy manufacturer or retailer, it is a good idea to pay attention to the following points.
- Is there clear information provided about the origin and quality of raw materials?
- Are the manufacturing process and quality control system explained in detail?
- Are you responding to consumer inquiries in a courteous manner?
- What are the reviews and ratings from other consumers?
It is also important to check the expiration date and storage method when actually purchasing a product. Reputable manufacturers and retailers recommend proper storage methods to maintain product quality and strictly manage expiration dates. By choosing a reliable manufacturer or retailer, you can purchase rice flour products with peace of mind and enjoy delicious, healthy eating.
The benefits of homemade rice flour and how to make it
In addition to purchasing rice flour products, we also recommend making your own rice flour. Homemade rice flour allows you to choose and mill your favorite rice, allowing you to control the taste and nutritional value. It can also be milled without additives or processed foods, allowing you to enjoy a more natural taste. To make your own rice flour, follow these steps:
1. Wash the rice and soak it in water for about half a day or overnight.
2. Drain the absorbed rice and dry it thoroughly.
3. Finely grind the dried rice using a blender or food processor.
4. Sift the ground rice flour to remove coarse particles.
5. Store in an airtight container in the refrigerator or freezer.
Homemade rice flour tastes even better when it's freshly ground. You can also control the texture of your dishes and sweets by adjusting the fineness. However, homemade rice flour has a short shelf life, so it's important to make only the amount you can use up. You also need to be careful about hygiene. When milling, use clean equipment and be careful not to let moisture or insects get in. Using homemade rice flour will allow you to enjoy rice flour products that are tailored to your tastes.
Tips for using rice flour effectively
How to choose the right rice flour for your needs
To use rice flour effectively, it is important to choose the appropriate rice flour for the purpose. There are various types of rice flour, such as those for confectionery, bread making, and cooking, and each has characteristics that are suited to its purpose. Rice flour for confectionery is characterized by its fine and smooth texture, making it suitable for making sweets such as cookies and cakes.
On the other hand, rice flour for bread making has a higher protein content to give bread rise and elasticity. Rice flour for cooking is an all-purpose rice flour that can be used for a wide range of dishes, including pasta, pizza, and fried chicken batter. When choosing rice flour, it is a good idea to refer to the intended use listed on the package. The taste and texture also vary depending on the ingredients and manufacturing method of the rice flour. It is important to choose the rice flour that suits you best by searching for the taste and texture you prefer.
Adjusting moisture content and preventing dryness
When cooking or making sweets using rice flour, adjusting the amount of water is key. Rice flour has the property of absorbing water more easily than wheat flour, so if you use the amount of water specified in the recipe, the dough may become too hard. Therefore, when making the dough, it is important to add water little by little and check the texture. As a guideline, it is best to use about 10-20% less water than when using wheat flour.
Additionally, dough made with rice flour tends to dry out easily. If the dough dries out, it will become dry and crack, so it is important to take measures such as frequently covering the surface of the dough with a wet cloth. It is especially important to take care to prevent the dough from drying out when making dishes that require fermentation, such as bread or pizza dough. Wrapping the dough in plastic wrap or letting it ferment in a humid place to prevent it from drying out will help ensure a delicious final product.
Use of connecting materials
When cooking or making sweets using rice flour, using a binding ingredient is also an important point. Rice flour has less gluten than wheat flour, so the dough tends to be difficult to hold together and tends to crumble. Therefore, adding a binding ingredient can improve the dough's hold and texture. Typical binding ingredients include eggs, mayonnaise, yogurt, and tofu.
These binding ingredients give the dough moisture and elasticity, improving its hold. Adding binding ingredients can also increase nutritional value and flavor. For example, adding tofu allows you to consume protein and soy isoflavones. Adding yogurt adds lactic acid bacteria and the flavor of dairy products. The type and amount of binding ingredients vary depending on the type of dish or sweet, so it's important to refer to the recipe and adjust to your preferred texture and flavor.
Storage methods and freshness control
Rice flour has a shorter shelf life than wheat flour, so care must be taken with storage and freshness management. Rice flour is susceptible to moisture and insects, so it is important to store it in an airtight container in a cool, dark place. Once opened, try to use it up as quickly as possible. For long-term storage, we recommend storing it in the refrigerator or freezer.
If storing in the refrigerator, it is best to store it in an airtight container and use it within about a month. If storing in the freezer, it is best to store it in an airtight container and use it within about three months. However, frozen rice flour tends to clump together after thawing, so it is important to mix it well before using. Also, try to eat dishes and sweets made with rice flour as soon as possible. In particular, since dough-like products tend to dry out and deteriorate quickly, it is best to eat them by the end of the day or the next day. By paying attention to how you store rice flour and how to maintain its freshness, you can use it safely and deliciously.
