5. Cultural Differences and Their Impact on β - Carotene Utilization

5.1 In China

Chinese cuisine has a long history and unique cooking methods. The way of preparing food often affects the utilization of β - carotene. For example, some traditional Chinese cooking methods such as stir - frying may cause some loss of β - carotene due to high - temperature treatment. However, at the same time, Chinese people also like to eat some raw vegetables in cold dishes, which helps to retain β - carotene.

Chinese cultural traditions also influence the choice of food sources of β - carotene. For example, during certain festivals, specific foods rich in β - carotene are often eaten. This not only meets the nutritional needs but also reflects cultural significance.

5.2 In the United States

American food culture is more diverse, with a combination of various ethnic cuisines. In American cuisine, the preference for raw or lightly cooked foods in some cases helps to better preserve β - carotene in fruits and vegetables. For example, salads are a very common part of the American diet, which allows for the direct consumption of β - carotene - rich ingredients.

The concept of convenience in American culture also affects the consumption of β - carotene - rich foods. For example, the popularity of ready - to - eat fruits and vegetables and processed foods means that consumers can easily obtain β - carotene - containing products, but at the same time, some processing methods may also cause a certain amount of nutrient loss.

6. Scientific Research Trends
