Blueberries Frozen

The whole, ripe, sound, frozen fruit has been cleaned, washed, stemmed, packed, blast frozen and maintained at freezer temperatures until required for use. The berries are USDA Grade A and are purple-blue, possessing a sweet/tart flavor balance

18 months minimum at zero degrees Fahrenheit

 

Research on the potential antidisease effects of blueberries

Researchers have shown blueberries contain pterostilbene, anthocyanins, proanthocyanidins, resveratrol, flavonols, and tannins, which inhibit mechanisms of cancer cell development and inflammation in vitro.^{[26][27][28][29]} Similar to red grape, some blueberry species contain in their skins significant levels ofpterostilbene,^[30] a phytochemical.

Although most studies below were conducted using the highbush cultivar of blueberries (V. corymbosum), content of polyphenol antioxidants and anthocyanins in lowbush (wild) blueberries (V. angustifolium) exceeds values found in highbush species.^[31]

At a 2007 symposium on berry health benefits, reports showed consumption of blueberries (and similar berry fruits including cranberries) may alleviate the cognitive decline occurring in Alzheimer's disease and other conditions of aging.^[22]

Proanthocyanidin, a chemical isolated from blueberry leaves, can block replication of the hepatitis C virus and might help to delay disease spread in infected individuals if ingested as a dietary supplement at a dosage 1/100th of the toxic threshold.^[32]

Feeding blueberries to animals lowers brain damage in experimental stroke.^[33][34] Research at Rutgers^[35] has also shown that blueberries may help prevent urinary tract infections.

Dr. Arpita Basu, an assistant professor of nutrition at Oklahoma State University, showed in several laboratory-based animal and cell studies that anthocyanins, found in blueberries, cause blood vessels to relax and increase production of nitric oxide that helps in maintaining normal blood pressure.^[36]

Other animal studies found blueberry consumption lowered cholesterol and total blood lipid levels, possibly affecting symptoms of heart disease.^[37]Additional research showed that blueberry consumption in rats altered glycosaminoglycans which are vascular cell components affecting control of blood pressure.^[38]

A study soon to be published in the Journal of Agricultural and Food Chemistry found supplementation of diets with wild blueberry juice enhanced memoryand learning in older adults, while reducing blood sugar and symptoms of depression.^[39]
