Final answer:
The assertion that Mexican Americans typically start consuming more low- or non-fat milk and aged cheeses after immigration is false. Dietary habits after immigration are influenced by a complex interplay of assimilation, cultural identity, and the host country's immigration history.
Step-by-step explanation:
The statement that after immigration it becomes more typical for Mexican Americans to drink low- or non-fat milk and eat aged cheeses is false. When immigrants move to a new country, their dietary habits are influenced by various factors, including economic conditions, cultural assimilation, and food availability. The migration-ethnicity dynamic shows that what Americans eat is greatly influenced by the country's immigration history, with earlier European immigrants establishing many American foodways. However, it isn't inherently true that Mexican Americans will adopt consumption of lower fat milks or aged cheeses. Factors such as levels of lactose tolerance within populations, prevalent in places like Wisconsin with significant European heritage, influence local demand for dairy products. The temperance movement, related to increasing urbanization and immigration, is a different socio-historical phenomenon that isn't directly associated with Mexican Americans' dairy consumption habits.
In contrast, Mexican cultural identity has been described as cohesive and 'monolithic' due to high rates of intermarriage and a melting pot dynamic, lessening the chances of aggressive discrimination against constituent elements of their culture. This can affect how Mexican immigrants maintain their food traditions or adopt new ones. Indeed, American food practices have been shaped by contributions from different immigrant groups, creating a complex tapestry rather than a uniform dietary transition after immigration, as the experience varies across ethnicities and immigrant communities.
