Final answer:
Kale and carrots exemplify the recommendation to "vary your veggies" as they offer different colors, textures, and a diverse range of nutrients essential for a balanced diet, including high nutrient densities of vitamin K and vitamin A respectively. Option a.
Step-by-step explanation:
Kale and carrots best illustrate the dietary recommendation to "vary your veggies" because they have different colors and textures. This variety is not only visually appealing but also indicates a range of nutrients that can contribute to a balanced diet. Kale is a dark green vegetable that is significantly high in vitamins, minerals, and fiber, and it is particularly dense in nutrients like vitamin K. Carrots on the other hand, while also rich in fiber and nutrients, are best known for their high vitamin A content, predominantly in the form of beta-carotene which gives them their orange color.
Moreover, eating a variety of vegetables is recommended because it helps to ensure that you consume a complete profile of the essential nutrients required for health. It also reduces the risk of having an excess of some nutrients while lacking others, which can occur with a monotonous diet. The principle of consuming a variety of vegetables aligns with the MyPlate dietary guidelines, which suggest filling half of your plate with fruits and vegetables to maintain a balanced diet and maximize nutrient intake.
