Looking for that summer glow in the dead of winter? Look no further than this sweet potato, butternut squash, carrot and ginger soup! According to the USDA nutrient database, one cup of butternut squash has 457% of the recommended daily vitamin A, while one cup of sweet potato has 769%, and one cup carrot contains 428%! Vitamin A contains beta-carotene that, with the consumption of dietary fat, can accumulate in the skin, making the pigmentation brighter. Also, ginger and cayenne have been recently shown to alleviate joint pain in a double-blind, placebo-controlled study.
