8 Reasons For Eating Blueberries And Why You Have To Freeze Them


One new research has discovered that freezing the blueberries can increase the nutritional content of this fruit. Marin Plumb, who is a graduate student and a food science major at the South Dakota State University, discovered that frozen blueberries are the same nutritious like the fresh blueberries, even after 6 months of freezing.

Her experiment involved observing the antioxidant levels in blueberries frozen for 1, 3 and 5 months. After making a comparison between the antioxidant content of frozen berries to fresh berries, she discovered no increase in the nutritional value of the berries that were frozen. Plumb noted that the freezing process increases the anthocyanin concentration.

She explained that the ice crystals that are formed during the process of freezing disturb the structure of the plant tissue, and that makes the anthocyanins more available. Anthocyanins are a group of antioxidant compounds and they provide many systems in the body with protection.

Blueberries might be the healthiest food in the world

Professor Basil Dalaly, who is Plumb’s research adviser and teaches a course on phytochemicals – the naturally occurring chemical compounds in vegetables and fruits said that the blueberries go head to head with pomegranates and strawberries in antioxidant capacity.

Dalaly added that when it comes to eating healthy foods – the redder or greener, the better.

It is no coincidence that people connect the bright color with nutrition. Anthocyanin that works wonders in the bodies, also is the colorful pigment that is able to give many foods their color.

Organic blueberries contain higher nutritional content than the conventional berries

Don’t believe those industry studies that claim organic food is the same in nutrition to conventional, it is not true.

One study compared the total antioxidant capacity of the organic versus non-organic blueberries and discovered that the organic blueberries had importantly higher total anthocyaning antioxidants and higher concentrations of phenol antioxidants than the conventional berries.
