eat their food. When exposed to another culture for an extended period of time, individuals tend to take aspects of the "host" culture's food customs and implement them with their own. In cases such as these, acculturation is heavily influenced by general food knowledge, or knowing the unique kinds of food different cultures traditionally have, the media, and social interaction. It allows for different cultures to be exposed to one another, causing some aspects to intertwine and also become more acceptable to the individuals of each of the respective cultures. Controversies and debate Definitions Anthropologists have made a semantic distinction between group and individual levels of acculturation. In such instances, the term transculturation is used to define individual foreign-origin acculturation, and occurs on a smaller scale with less visible impact. Scholars making this distinction use the term "acculturation" only to address large-scale cultural transactions. Acculturation, then, is the process by which migrants gain new information and insight about the norms and values of their culture and adapt their behaviors to the host culture. Recommended models Research has largely indicated that the integrationist model of acculturation leads to the most favorable psychological outcomes and marginalization to the least favorable. While an initial meta-analysis of the acculturation literature found these results to be unclear, a more thorough meta-analysis of 40 studies showed that integration was indeed found to have a "significant, weak, and positive relationship with psychological and sociocultural adjustment". A study was done by Berry (2006) that included 7,997 immigrant adolescents from 13 countries found that immigrant boys tend to have slightly better psychological adaptation than immigrant girls. Overall, immigrants in the integration profile were found to be more well-adapted than those in other profiles. Perceived discrimination was also negatively linked to both psychological and sociocultural adaptation. Various factors can explain the differences in these findings, including how different the two interacting cultures are, and degree of integration difficulty (bicultural identity integration). These types of factors partially explain why general statements about approaches to acculturation are not sufficient in predicting successful adaptation. As research in this area has expanded, one study has identified marginalization as being a maladaptive acculturation strategy. Typological approach Several theorists have stated that the fourfold models of acculturation are too simplistic to have predictive validity. Some common criticisms of such models include the fact that individuals don't often fall neatly into any of the four categories, and
