Final answer:
For vitamin A during Thanksgiving, orange vegetables such as sweet potatoes, pumpkins, and carrots are the best choice due to their high carotene content. Dark green vegetables are also a good source.
Step-by-step explanation:
The best choice for providing vitamin A during Thanksgiving would be orange vegetables such as sweet potatoes, pumpkins, and carrots. These foods are rich in carotene, the pigment required by the body to synthesize vitamin A, which is crucial for healthy skin, bones, teeth, and vision. Although many Thanksgiving foods contain varying amounts of nutrients, orange vegetables are particularly high in vitamin A.
Other sources of vitamin A to consider for a Thanksgiving meal might include dark green vegetables like kale or spinach. While meats and dairy products such as liver and milk also provide vitamin A, the carotene from plant sources like orange and dark green vegetables is significant for a balanced diet.
