What specific plant compounds, indicated by the yellow flesh of the Yukon Gold, contribute to its overall antioxidant capacity?
Answer
Carotenoids (such as lutein and zeaxanthin)
The visual characteristic of the Yukon Gold—its rich, golden flesh—serves as an indicator of specific beneficial phytonutrients present within the tuber. These pigments are classified as carotenoids. While purple potatoes are distinguished by anthocyanins, the yellow hue signals the presence of carotenoids like lutein and zeaxanthin. These compounds function as antioxidants, meaning they help safeguard the body's cells against damage caused by unstable molecules, thereby adding to the potato's overall protective nutritional qualities, even if the concentration differs from deeply colored vegetables.
