Sour oranges, also known as Seville oranges or bitter oranges, might not be the first citrus fruit you reach for a quick snack, but don’t let their tartness fool you. These intriguing fruits pack a surprising punch of health benefits, distinct from their sweeter cousins like navel or Valencia oranges. Let’s delve into the world of sour oranges and uncover their nutritional value and potential impact on your well-being.
Nutritional Profile of Sour Oranges
Sour oranges are a treasure trove of essential vitamins, minerals, and antioxidants. They boast a substantial amount of Vitamin C, a well-known immune booster and a vital component for collagen synthesis, which is essential for skin health and wound healing.
Beyond Vitamin C, sour oranges contain Vitamin A, crucial for maintaining healthy vision, immune function, and cell growth. They also provide folate (Vitamin B9), important for cell division and DNA synthesis, making them especially beneficial for pregnant women.
