Brown Rice Gains Popularity for Health Benefits; Online Searches Up 24% Over the Past Decade

The trend toward healthier eating is driving renewed interest in brown rice. According to Japan’s Brown Rice Food White Paper 2025, online searches for brown rice have increased by 24% over the past decade, while the market for health-focused grains continues to grow.

TOKYO, JAPAN (MERXWIRE) – As consumer health awareness rises, brown rice has attracted more attention. The Brown Rice Food White Paper 2025, released by the Multi-Function Brown Rice Association in Japan, highlights the significant growth of the brown rice market. Google Trends data also show that online search interest in “brown rice” has increased by approximately 24% over the past ten years, reflecting growing public interest in its nutritional value and ways to incorporate it into daily meals.

The main difference between brown rice and white rice lies in processing. White rice is milled to remove the bran and germ layers, while brown rice retains these layers, making it a whole grain. According to Japan’s Standard Tables of Food Composition, the calorie difference between the two is minimal, but brown rice contains significantly higher nutrients. For example, brown rice provides about 3 grams of dietary fiber per serving, compared to just 0.5 grams in white rice. It also contains 1.2 milligrams of vitamin E, compared with 0.1 milligrams in white rice, and 119 milligrams of magnesium versus 23 milligrams in white rice. Studies indicate that roughly 90% of rice nutrients are concentrated in the bran layer, making brown rice a rich source of vitamins and minerals.

Despite its nutritional benefits, brown rice has long been perceived as harder to cook and more fibrous in texture. The white paper notes that people who rarely eat brown rice cite “cooking difficulty,” “limited opportunities to eat it,” and “family preferences” as major reasons. To address this, the industry has developed “easy-to-cook brown rice” varieties. Through improvements in rice breeding and processing techniques, these products maintain brown rice’s nutritional value while offering a softer texture and easier preparation, more similar to white rice.

Restaurants and fast-food outlets have also started offering brown rice dishes, allowing consumers to try it conveniently outside the home. Online search trends reveal high interest in keywords such as “how to cook brown rice,” “brown rice enzymes,” and “brown rice diet,” indicating that consumers are concerned not only with nutrition but also with health effects and preparation methods.

The white paper reports that between April 2023 and March 2024, Japan’s household market for health grains reached 15.98 billion yen, a 6.2% increase from the previous year. Refined barley, the largest category by market share, grew 2.9%, rebounding after recent declines. Mixed grains continued steady growth, achieving double-digit growth of 11.2% last year, partly driven by young women viewing them as part of a beauty and health-conscious diet. Processed brown rice showed the most notable increase, rising 19.8% due to its combination of convenience and nutritional benefits, expanding its market share as brown rice gains popularity.

Analysts attribute the growth of the health grain market both to rising health awareness and to increasing rice prices, which have prompted households to mix in barley or other grains to extend rice portions and reduce food costs. By category, processed brown rice grew 25.6%, germinated brown rice 24.7%, barley 20.6%, and mixed grains 8.3%, demonstrating strong demand across all main product segments.

Kanto Smart Living Cooperative recommends that consumers looking to incorporate brown rice into their daily diet start by mixing it with white rice, allowing them to gradually adapt to its flavor and texture. They also suggest choosing germinated or processed brown rice products that are easier to cook, enabling people to enjoy the nutritional benefits of whole grains while maintaining convenience in everyday meals.
