Blueberries’ color is caused by anthocyanin. The term anthocyanin is taken from the Greek words antho (flower) and kyanos (sky) (meaning blue). In terms of color, the anthocyanin family of natural pigments ranges from dark red to deep blue, indigo, and violet, depending on how acidic the pigment is. A range of pH values affects anthocyanins. At low pH, pigments turn redder. At high pH, pigments turn redder still before finally turning purple, blue, green, and yellow.
Other people say that it’s deep purple. Some say it’s deep blue or a combination of glorious deep blue-indigo hue. Whatever it is, now you know what causes its color.
Blueberries have a lot of anthocyanins, which are powerful antioxidants that help keep people healthy. Anthocyanins work by absorbing ultraviolet (UV) light and making this dark blue/purple color, which will attract bees for pollination and help the plant grow. If the berries stay out in the sun for a long time, they will have more anthocyanins in them, which will make them darker in color.
The interior of a blueberry varies in color from deep blue in wild varieties to pale green or white in cultivated varieties. The inside of most store-bought blueberries is a pale color, which is normal.

Keeping Strong Bones
It contains calcium, iron, phosphorus, magnesium, zinc, and Vitamin K. These vitamins and minerals help maintain and build bone strength and structure.
Zinc and iron are essential nutrients for maintaining bone and joint toughness and elasticity.

Mineral intake is thought to lower blood pressure.
Blood sugar, lipids, and insulin levels are higher in people with type 1 diabetes who eat high-fiber diets than those with type 2 diabetes who eat the same diet. 3.6 g fiber per cup of blueberries.
During the study, 6.5% of participants developed diabetes. The researchers found that blueberries, raisins, grapes, apples, and pears reduced the risk of developing type 2 diabetes by 7% when eaten thrice weekly. In Addition, blueberries and blackberries may benefit people with diabetes due to their low glycemic index and high fiber content. Both berries are also rich in antioxidants, which can help to reduce inflammation and oxidative stress in the body, which are common complications associated with diabetes.
Heart Disease Prevention
Blueberries are high in heart-healthy nutrients. Potassium, dietary fiber, vitamin C Blueberries’ vitamin B6, vitamin C, and phytonutrients may help heart health. The heart can benefit from blueberry cholesterol elimination. Lower cholesterol levels indicate a lower risk of heart disease.
A substance called homocysteine can be prevented by vitamin B6 and folate. Blood vessel damage from high levels of homocysteine may cause heart issues. Most of the study’s results came from those who ate three portions of strawberries or blueberries per week.
In addition to vitamin C and vitamin A, the many phytonutrients found in blueberries provide powerful antioxidant protection against free radical damage.
Enhanced Mental Health
Blueberry consumption has been linked to a slow decline in cognitive function in older women. It has been shown to improve short-term memory and reduce the risk of cognitive impairment.
Reducing Weight and Maintaining a Healthy Digestive System
