Sweet Potatoes 地瓜
Eating this brilliant vegetable is like giving your body a beauty treatment, thanks to its high concentration of beta carotene (the healthful antioxidant that gives this spud its orange hue). Beta carotene, which has been shown to help every cell in the body stay healthy, also happens to be a skin-targeted nutrient. Studies have shown it neutralizes wrinkle and sun spot-spurring damage from the sun and helps generate new, healthy glowing skin cells. Sweet potatoes are also packed with a slew of figure-friendly fiber and energizing B-vitamins -- all for just 43 cents a serving.

吃这种优秀的食物会让你的美丽更上一层楼，由于它所含的大量的β胡萝卜素（让地瓜带上橘色的健康抗氧化剂）。β胡萝卜素已被发现可以帮助身体里的每个细胞保持健康，而且很巧，它还是针对皮肤的营养物。研究表明，它可以缓解皱纹和晒斑、晒伤，并帮助长出新的、健康的皮肤细胞。地瓜也含有大量有益人体的纤维素和带来活力的维他命B——所有这些这只要43美分。
