Final answer:
Scientists can assess the health risks of trans fats through experiments on animals, analyzing historical data, performing clinical trials on humans, and developing mathematical models.
Step-by-step explanation:
Scientists can assess the health risks of trans fats through a combination of different methods. One approach is to conduct experiments on animals, such as mice and rats, to observe the effects of trans fats on their health. This can provide valuable insights into potential risks for humans. Another method is to analyze historical data, such as epidemiological studies, to identify correlations between trans fat intake and health outcomes in human populations. Additionally, scientists may perform clinical trials on humans to directly study the effects of trans fats on their health. Finally, scientists can also develop mathematical models to simulate and predict the health risks of trans fats.
