ASIAN CASE STUDY - MIAO

MIAO, SICHUAN, CINA

Community Food System Datatables

Introduction

Location of Miao Health Study Sites

This field study was carried out in the town of Gongquan in Gong county within the Sichuan province of China. The Sichuan province is one of the seven provinces where 8 million Miao minority nationalists have now migrated to. Such wide-spread migrations have resulted in the many distinct yet similar languages, foods and clothes of the Miao today. The Miao are said to be one of the most ancient and largest nationalities of China.

Notes on food groups

The information on various foods consumed by Miao was gathered in the Sichuan province. Due to financial constraints, sampling and nutrient analysis of only 4 foods were possible (refer to pages 45 – 48 in ‘Vegetable Category’. These foods are not currently found in the national Chinese food composition database. Nutrient analysis was carried out by the Department of Food Chemistry at the National Institute of Nutrition and Food Hygiene (INFH) in Beijing. All other information was gathered by focus group discussion and individual interviews carried out within the community.

Users should be aware that the data presented here do not represent absolute values. The purpose of this publication is to present a true reflection of the usual composition of foods as available and/or consumed among Miao community members. This is a living document and nutrient information will be added and/or updated when available.

Data were collected for a total of 80 food items which were then divided into seven food groups:

  1. Maio Datatables: Cereals and Millet
  2. Miao Datatables: Vegetables
  3. Miao Datatables: Fruit
  4. Miao Datatables: Nuts
  5. Miao Datatables: Meat
  6. Miao Datatables: Fish
  7. Miao Datatables: Miscellaneous Foods

Apart from the four local foods, nutrient information for the remaining foods is mainly sourced from the China Food Composition Database, 2002 (electronic version) which is referenced in the tables.

Local food names are recorded by either their local names or by mandarin names along with Chinese descriptor. The Scientific identification and English names were also determined when possible.

Notes on food components

There are approximately 16 to 18 components in the main body of the tables, which are presented in a fixed format for each record. The order of presentation is based on major nutrients categories.

The information on the analytical details for majority of the components can be obtained from the referenced literature.

Energy

Energy is expressed in unit of kilocalories (kcal). All energy values are calculated from the energy producing food components using the following conversion factors:

  • Protein: 4 kcal/g
  • Carbohydrate: 4 kcal/g
  • Fat: 9 kcal/g
  • Alcohol: 7 kcal/g

The calculated energy value of some foods in the tables varies from the energy value reported in the China Food Composition Database, 2002.

Carbohydrate

The carbohydrate content of food in the tables is reported in g/100g of edible portion (EP) was estimated as:
Carbohydrate=100 – (Water + Protein + Fat + Ash)

Dietary fibre

The dietary fibre content shown in the tables refers to insoluble fibre, determined using the neutral detergent method. Insoluble fibre includes cellulose, insoluble hemicellulose, and lignin etc. The fibre content is shown as g/100g of EP for each food.

Vitamin A

Vitamin A values are reported in only Vitamin A retinol equivalents (RE-μg) and are sourced from China Food Composition Database 2002. Vitamin A RAE values are calculated and reported for compatibility with the DRI (Dietary Reference Intake) recommendations.
