Hi there! It's great you're curious about blue foods. As a food scientist, I spend a lot of time thinking about the colors of food, their natural origins, and how they influence what we choose to eat. You might be surprised to know that truly blue food is pretty rare in nature! Let's dive into the world of blue hues found in our food.
**Blueberries and Beyond: Anthocyanins at Play**
When you think of blue food, blueberries are likely the first thing to pop into your head. And yes, they get their beautiful blue hue from anthocyanins. These pigments are responsible for a wide range of colors in fruits and vegetables, from red and purple to blue. The exact shade expressed depends on factors like pH and the presence of other pigments within the plant.
But here’s the thing: blueberries aren't really blue, at least not in the way we perceive color. They have a high concentration of anthocyanins, which absorb most wavelengths of light except blue, which gets reflected back to our eyes.
**Other naturally blue-hued foods colored by anthocyanins include:**
* Blue corn: A staple in some cultures, blue corn gets its color from the same pigments found in blueberries.
* Concord grapes: These grapes are practically bursting with anthocyanins, giving them a deep blue-purple hue.
**The Case of Spirulina: A Blue-Green Algae**
Spirulina, a type of blue-green algae, deserves special mention. It's become increasingly popular as a dietary supplement due to its nutrient profile. Spirulina contains phycocyanin, a blue pigment that acts as a powerful antioxidant.
While spirulina itself has a blue-green color, it's important to note that it's often dried and sold as a powder or incorporated into food products. This means the intensity of the blue color can vary.
**The Illusion of Blue: Food Coloring's Role**
Now, let's talk about those vibrant blue candies, frostings, and sports drinks. It’s highly likely that these treats get their electric blue color from artificial food coloring, such as Brilliant Blue FCF (FD&C Blue 1) or Indigo Carmine (FD&C Blue 2). These synthetic dyes are created in labs and are very effective at producing a wide range of shades of blue.
A Note About Safety
While most blue foods are perfectly safe to consume, it's important to be mindful of artificial food coloring. Some individuals may experience adverse reactions to certain dyes. Always check ingredient lists carefully and choose natural options whenever possible.

Most people will start with blueberries, because the fruit looks blue and the word blue is in its name. ... There are potatoes called --blue potatoes,-- and we all know about blue corn chips. Yet we discovered in the video that there truly are no blue foods.
