Final answer:
The statement is false as fast-food advertisements usually emphasize taste and convenience rather than the high levels of salt and fat. This strategy is used to increase sales.
Step-by-step explanation:
The statement 'Most fast-food advertisements focus on the high levels of salt and fat contained in the food' is false. In fact, fast-food companies tend to highlight the pleasurable qualities of their products, such as taste, convenience, and enjoyable experiences, rather than the potentially harmful nutritional components. These typical marketing strategies aim to drive sales, not health consciousness, which could deter consumption if consumers were regularly reminded of the high amounts of salt and fat in fast food.
