Blue fruits are rare in nature and finding one that is truly blue is really hard. Although there are several fruits that seem to be blue, they are actually shades of purple thanks to the combination of anthocyanins (which are blue) and carotins (which are red).
Not only that, according to experts, the type of color and pigment anthocyanins create depends on their quantity and the pH inside the plant tissue. Luckily, I have discovered quite a list of fruits that are various shades of blue and purple.

BENEFITS OF BLUE & PURPLE FRUITS FOR YOUR BODY
Blue foods, including fruits, are rich in blue and purple pigments. These pigments are invaluable for your health as these are very potent antioxidant and anti-inflammatory substances.
In fact, main substances that I am talking about include phytochemicals such as anthocyanins and resveratrol. According to website Ahealthiermichigan.org, blue foods provide many health benefits to your body:
- Help fight inflammation
- Improve the bodies ability to absorb calcium and other nutrients
- Help to lower LDL cholesterol (which is the “bad” cholesterol)
- Support eye health, specifically health of the retina
- Help to boost the immune system
- Support healthy digestion for the GI tract
- Act as anticarcinogens (battles cancer-causing cells) especially throughout the digestive tract
- Reduce tumor growth
- Limit the activity of cancer cells throughout the body
Because these are claims made by the third party website, I have decided to have a look at what the scientific community states about these active compounds in blue foods.
To my surprise, there have been conducted many research studies that have been dealing with either anthocyanins or resveratrol. Except for those studies I have linked in the list above, I have discovered that anthocyanins also help to reduce effects of Alzheimer´s disease, and help protect your liver.
Did you know that there are certain fruits (such as wild blueberries) that when cooked, experience a significant breakdown of carotin (red color) leading to bluer looks?
Also, I have one surprise for you at the end of this article. According to spectrophotometer measurements conducted in this video, there are no truly blue foods out there. Those on this list are more on a purple scale.
