  • Blue Corn has a blue hue, and is part of a variety of dishes, such as tortilla chips, tacos, or cornbread.
  • Blue Tomatoes have a sweeter and more complex flavor compared to red tomatoes. You can use them in salads, sandwiches, sauces, or as a garnish.

How do these Veggies get their Beautiful Blue Hue?

The blue is due to the presence of pigments called anthocyanins. These pigments give fruits, flowers, and vegetables their red, purple, and blue colors.

Anthocyanins can change color depending on the acidity of the surrounding environment.

Blue potatoes and blue cauliflower sometimes appear more purple or violet, depending on the acidity of the soil in which they are grown.

Skin health benefits :

  • Anti-inflammatory properties reduce redness, swelling, and irritation in the skin.
  • Antioxidants protect the skin from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to the aging process.
  • UV protection: Anthocyanins may help protect the skin from damage caused by UV radiation from the sun.
  • Collagen production: Anthocyanins stimulate collagen production in the skin, which can help improve skin elasticity and reduce the appearance of fine lines and wrinkles.
  • Moisturizing properties improve skin’s hydration and prevent dryness.
