英文文献摘要：
As immigrants settle and extend their stay in the U.S., they may be exposed to a food culture and lifestyle that impacts their food choice decisions and health outcomes. This paper focuses on the behavioral changes and acculturation level of different generations of Asian immigrants on food choice decisions employing the 2013 American Time Use Survey. Heckman two-step regression results indicate that the 1st generation immigrants participate or spend more time on eating and drinking, food preparation, and grocery shopping; and less in travel related eating and drinking compared with natives. The 1st generation is least likely to acculturate into American food culture. The 1.5 generation behaves more similarly to natives regarding the four food choice decisions, and appears to acculturate over time. The 2nd generation shows no significant difference to natives. Immigrants acculturate by food habit change from food at home to food away from home.
