Nowadays, more and more health-conscious people are choosing brown rice instead of white rice, thinking it is more natural and nutritious. From a nutritional perspective, brown rice wins in terms of vitamins, minerals and dietary fiber. But what you may not know is that this “healthy staple” isn’t for everyone. Especially for children and the elderly with weak digestive functions, eating too much will hurt their stomach and intestines. So, what is the difference between brown rice and white rice? Who is more suitable to eat which rice?
What are the nutritional differences between brown rice and white rice?
Simply put, brown rice is "semi-processed" rice that only removes the outer shell, retaining the nutrient-rich germ, aleurone layer and seed coat.; The white rice (polished rice) we often eat has been milled many times to remove these parts, leaving only the endosperm, which is mainly starch.
Because of this, brown rice contains a lot more B vitamins, vitamin E, calcium, iron, potassium and dietary fiber than white rice. For example, under the same weight, the dietary fiber content of brown rice is more than three times that of white rice, and the B vitamins are several times higher. Eating only white rice for a long time can easily lead to vitamin B1 deficiency, causing fatigue, beriberi and other problems.
In addition, the dietary fiber in brown rice can delay the rise of blood sugar, help control weight and prevent diabetes, and is especially beneficial to people with high blood pressure.
What are the benefits of eating brown rice?
1. Promote digestion
Brown rice is rich in dietary fiber, including soluble and insoluble fiber, which can stimulate intestinal peristalsis, increase stool volume, and promote the balance of intestinal flora. It can effectively relieve constipation and reduce the accumulation of intestinal toxins. Long-term consumption can improve intestinal digestive function and reduce the risk of intestinal diseases. It is suitable for people with daily constipation.
2. Stable sugar control
The glycemic index (GI value) of brown rice is lower than that of white rice, and carbohydrates release energy slowly, which can avoid rapid fluctuations in blood sugar. Its dietary fiber can also delay glucose absorption and help stabilize blood sugar levels after meals. It is a high-quality staple food choice for diabetic patients. It is recommended to replace refined white rice in appropriate amounts.
3. Lower cholesterol
The bran of brown rice is rich in phytosterols, which can compete with cholesterol for absorption sites in the intestine and reduce the body's absorption of dietary cholesterol. At the same time, dietary fiber can promote cholesterol excretion, help reduce low-density lipoprotein cholesterol in the blood, and play a protective role in cardiovascular health.
4. Enhance satiety
Brown rice has lower calories than white rice and is high in dietary fiber. After eating, it can bring a stronger feeling of fullness and reduce the intake of other high-calorie foods. Its digestion and absorption rate is slow, which can extend the duration of satiety and avoid frequent hunger. It is an ideal staple food substitute for people losing fat and helps control total caloric intake.
Who is suitable to eat white rice?
1. People with weak digestive function
White rice has been carefully processed to remove the indigestible rice bran and germ, making the starch structure more easily decomposed and absorbed. It is suitable for the elderly, children, patients with gastrointestinal diseases or people recovering from surgery. It can quickly replenish energy, avoid the burden on the gastrointestinal tract caused by the dietary fiber of brown rice, and reduce the risk of bloating and diarrhea.
2. People who need quick energy replenishment
White rice has a high glycemic index and carbohydrates can be quickly converted into energy, making it suitable for manual workers, athletes or long-term high-intensity workers. It can quickly relieve fatigue, restore physical strength, and meet the body's demand for immediate energy. Eating it with protein and vegetables can improve nutritional balance.
3. People with low blood sugar or special health conditions
People with low blood sugar often experience symptoms such as dizziness and fatigue. White rice can quickly raise blood sugar and relieve discomfort.; Some people with intestinal malabsorption cannot effectively digest the dietary fiber of brown rice. Eating white rice can ensure their caloric and nutrient intake and avoid malnutrition caused by poor digestion and absorption.
Brown rice is more nutritious than white rice, but "healthy" doesn't mean "suitable for everyone." Reasonable matching and adapting measures to individual conditions are the real way to maintain health. Ordinary people can eat brown rice 2 to 3 times a week, which not only supplements nutrition but does not increase gastrointestinal burden.
