Summary of Research Findings

According to the consumer survey conducted in July 2018 regarding the materials of functional and health food directed at 1,000 men and women in their ages between 30s and 70s who consume health food in their daily lives (almost every day or whenever necessary), those that achieved 10% or more of the intake ratio among the entire 37 materials by the respondents were the following six materials: DHA/EPA, Green Juice (or Aojiru), Blueberry, Collagen, LAB (Lactic Acid Bacteria), and Glucosamine.

When asked about the effects and functions of these popular 6 materials that acquired high ratio of intake, the most well-known effects were “improvement and maintenance of memory” by DHA and EPA, followed by health maintenance and improvement by green juice (Aojiru). The third place was occupied by Blueberry (Bilberry) with its expected ability to relieve eyestrain, followed by Collagen’s prospective ability to promote glowing and vibrant skin, LAB’s power to facilitate gastrointestinal motility, and Glucosamine’s relieving of arthralgia.

Noteworthy Topics

As mentioned above, those that achieved more than 10% for intake ratio out of 37 materials by the respondents (total 1,000 respondents), according to our research, were DHA/EPA which attained 19.1%, Blueberry (Bilberry) 15.9%, Collagen 14.8%, LAB (lactic acid bacteria) 13.1%, and Glucosamine 10.7%. 

For women (500 respondents), the popular materials attaining high ratio of intake in the descending order were: Collagen 23.8% exceeding 20%, followed by DHA/EPA 19.0%, Green Juice (Aojiru) 18.8%, Blueberry (Bilberry) 16.4%, and LAB (lactic acid bacteria) 12.6%. The materials at the sixth position until 10 in the order of the largest intake ratio by women were Glucosamine, Lutein, Heme Iron, Soybean Isoflavone, and Hyaluronic Acid, all of which show the women’s interest in improving and maintaining beauty or in taking measures against aging.   

For men (500 respondents), the popular materials achieving high ratio of intake in the descending order were: Green Juice (Aojiru) and DHA/EPA both equally achieving 19.2%, followed by Blueberry (Bilberry) 15.4%, LAB (lactic acid bacteria) 13.6%, and Glucosamine 11.2%. 

The materials at the sixth position until 10 by the ratio of intake by men were Protein, Lutein, Curcuma (Ukon), Collagen, and Soybean Isoflavone, which show how men try to build healthy body, adjust focus of their eyes, and take measures when drinking alcohol. In addition, there were Collagen and Soybean Isoflavone the materials popular among women. This seems to indicate that some materials that attained high ratio of intake by men include those taken with their spouse.
