Final answer:
The main food sources for vegetable and safflower oil are the oils themselves, not other food categories. These oils are used in a variety of dishes and are rich in unsaturated fats, which are healthier options in a balanced diet.
Step-by-step explanation:
The main food sources that include vegetable and safflower oil are not fruits and nuts, meat and dairy products, nor grains and legumes. Instead, these oils are part of the category that includes various oils such as canola oil, olive oil, and soybean oil, and are sourced from vegetables and safflower plants themselves. Foods commonly prepared with these oils include salad dressings, pastas, rice dishes, and cooked vegetables. Vegetable and safflower oils are rich in unsaturated fats, particularly polyunsaturated and monounsaturated fatty acids, which are beneficial in a balanced diet. It's important to choose oils wisely as part of a healthy diet, preferring those that are liquid at room temperature over solid animal fats like butter and lard.
