Just when you thought that the health benefits of blueberries couldn’t be any more plentiful, new research has found that freezing the superfood actually increases the berry’s nutritional content. Graduate student Marin Plumb, a food science major at South Dakota State University, found that frozen blueberries are equally nutritious as fresh blueberries, even after six months of freezing.
Plumb’s experiment involved observing antioxidant levels in blueberries frozen for one, three and five months. After comparing the antioxidant content of frozen berries to fresh berries, she found no decrease in the nutritional value of the frozen berries. In fact, Plumb noted that freezing actually increased the anthocyanin concentration.
“The ice crystals that form during freezing disrupt the structure of the plant tissue, making the anthocyanins more available,” Plumb explained. Anthocyanins are a group of antioxidant compounds that provide various systems in the human body with protection.
Blueberries May Be The World’s Healthiest Food…
“Blueberries go head-to-head with strawberries and pomegranates in antioxidant capacity,” said Plumb’s research adviser, professor Basil Dalaly, who teaches a course on phytochemicals, the naturally occurring chemical compounds in fruits and vegetables.
When it comes to eating healthy foods, “the greener or redder, the better,” added Dalaly.
It’s no coincidence that people associate bright color with nutrition. Anthocyanin, which works wonders in our bodies, is also the colorful pigment that gives many foods their color.
Organic Blueberries Have Higher Nutritional Content Than Conventional Berries…
Don’t believe industry studies that claim organic food is equal in nutrition to conventional; it’s simply not true.
A study directly compared the total antioxidant capacity of organically grown versus non-organically grown blueberries and found that the organic blueberries had significantly higher concentrations of phenol antioxidants and total anthocyanin antioxidants than conventional berries.
Below Are 8 Reasons To Consume Blueberries Daily
1. Improving Memory/Motor Function
One study found that older adults (average age 76) fed blueberries daily for 12 weeks (2-2.5 cups per day) performed better on two different cognitive function tests, which included memory, than those who hadn’t consumed the superfood.
2. Eye Protection
Blueberries have been proven to protect the retina from unwanted sunlight and oxygen damage.
Consuming blueberries significantly lowers your risk of developing heart disease by regulating and relaxing arterial elasticity in the vascular wall. They also improve blood flow.
