资源简介：
The health and Food-purchasing survey. Exact date has been masked by a small variable to protect participant identity. The variables j1, j2, j3, etc. stand for the JAN code (Japan Article Number code) which is a barcode standard compatible with the EAN (European Article Number). The JAN code has been masked so as not to identify the individual food products.
