1. Introduction


1.1 Definition of “health food” in Japan

Foods that are sold or used as items useful for maintenance and improvement of health are generally referred to as “health foods” in Japan. From the legal perspective, however, there is no explicit definition for the term, except from “foods with health claims” that is defined under Health Promotion Law.

1.2 Relevant laws and regulations

  • Food Sanitation Act

  • Food Safety Basic Law

  • Japanese Agricultural Standards Law

  • Health Promotion Law

  • Pharmaceutical Affairs Law

1.3 Classification of health foods in Japan

In Japan, health foods generally refer to “Foods with health claims (FHC)”, which are defined as foods that alter physiological functions and have characteristics between that of a drug and a conventional food. The definition includes so-called functional foods, and can be divided into two subcategories based on differences in purpose and function: “foods with nutrient function claims (FNFC)” and “foods for specified health uses (FOSHU)”. The former refers to the foods that are labeled with the functions of nutritional ingredients (vitamins and minerals), and the latter refers to the foods officially approved to claim a physiological effect on the human body. FNFC is the standard regulation system, consisting of 12 vitamins and 5 minerals, while FOSHU is an individual approval system, including four subcategories under it: ordinary FOSHU, standardized FOSHU, health claims for the reduction of disease risk, and qualified FOSHU.

1.3.2 Foods for Specified Health Uses (FOSHU)

Foods for specific health uses are foods that include functional health ingredients with physiological functions and biological activity on the body bearing claims relating to the expected changes in physiological functions that can be expected from intake of the food with the intention of achieving a specific health function.

When foods are sold as foods for specified health uses, a screening by the national government must be conducted concerning the efficacy of the individual physiological functions and specified health functions as well as safety, etc. and approval must be obtained.
 
Ordinary FOSHU: requires detailed review process with scientific evidence for each application

Standardized FOSHU:

  • No requirement of detailed review process for food products meeting the established standards and specifications

  • Must be accompanied by sufficient accumulation of scientific evidence

  • For efficiency: short cut process for products whose safety has already be assessed and approved

Reduction of disease risk FOSHU:

  • Requires detailed review process with scientific evidence for each application

  • Permitted for products whose ingredients clinically and nutritionally established to reduce a risk of certain disease (i.e., Calcium for Osteoporosis and Folic acid for neural tube defects)

Qualified FOSHU:

  • Requires detailed review process with scientific evidence for each application

  • Permitted for products with ingredients showing certain health effects but not reaching the established standards for FOSHU approval

  • Labeled as “Qualified Food for Specified Health Uses”

1.3.3 FOSHU health claims allowed

  • Gastrointestinal health

  • Cholesterol moderation

  • Hypertension moderation

  • Lipid metabolism moderation

  • Sugar absorption moderation

  • Mineral absorption

  • Bone health

  • Tooth health

  • Iron supplement

  • Maintain skin moisture

2. FOSHU approval


2.1 General procedure for approval of FOSHU

Those who wish to apply their products for FOSHU labeling are required to submit the following documentation:

Sample of the entire package with labels and health claims
Documentation that demonstrates clinical and nutritional proof for the product and/or its functional component for the maintenance of health
Documentation that demonstrates clinical and nutritional proof of the intake amount of the product and/or its functional component
Documentation concerning the safety of the product and its functional component, including additional human studies about the eating experience
Documentation concerning the stability of the product and its functional component
Documentation of the physical and biological characteristics of the product and the functional component
Methods of qualitative/quantitative analytical determination of its functional component, and analytical assay results of the component in the product
Report on the analysis of the designated nutrient constituents and energy content of the product
Statement of the production method, list of factory equipment, and an explanation of the quality control system

Mandated FOSHU documentation can be summarized into 3 essential requirements for FOSHU approval: 1) its effectiveness based on scientific evidence including clinical studies; 2) its safety as assessed from historical consumption pattern data and additional safety studies conducted in humans; and 3) analytical determination of the functional component responsible for the beneficial physiological action.

2.2 Flow chart of FOSHU approval

FOSHU was enacted under the Nutrition Improvement Law. This law lists five categories of “food for special dietary uses”: (1) milk powder for pregnant and lactating women; (2) formulated milk powder for infants; (3) foods for elderly individuals with difficulty in masticating or swallowing; (4) medical foods for the ill; (5) FOSHU
 
FOSHU applications are accepted every three months. The practical minimum period required for the approval process is approximately 1 year.
