36 Naturally Blue Foods List (Delicious & Healthy)

There is no shortage of blue foods, regardless of whether you are looking for health benefits or want to add some color to your plate.

You likely think of traditional blue foods like blueberries or plums, but did you know there are edible blue flowers? In addition, you can find several seafood items in vibrant blue colors, along with starches like corn or sweet potatoes.

Adding naturally blue foods to your diet is a great way to get antioxidants and other nutrients. However, several popular artificial blue foods made the list.

Before we dive into our thorough list of blue foods, let’s look at what gives them their color and how naturally blue foods can benefit you.

What Makes Blue Foods Blue?

While we know a bit of blue food coloring can make anything change color, have you wondered what makes naturally blue foods blue? Blue foods contain a pigment called anthocyanins, which is responsible for their color. Anthocyanins are also why raspberries are red, eggplants are purple, etc.

Some skeptics argue that most blue foods are purple and few genuinely blue foods exist. For example, during a segment on the Food Network, hosts used a spectrophotometer to detect the color of popular foods we would assume are blue.

However, the story revealed that most foods we think of as blue are purple because blue light is one of the highest energy wavelengths in the visible light spectrum.

Finally, with the power of food coloring, you can make almost any food turn blue, making for a fun, festive look.

Are Blue Foods Healthy?

Naturally blue foods are full of antioxidants and chock full of vitamins, making them a sensible food to add to your diet.

Blue foods are also known to prevent many diseases and provide significant benefits, including:

  • Certain cancers
  • Heart disease
  • Alzheimer’s
  • Type 2 diabetes
  • Improve cognitive health
  • Boost your mood

However, you should be aware of artificial blue foods that offer no health benefits. While they make for a great treat once in a while, they shouldn’t be a part of your daily diet.
