 Blueberry (Cyanococcus)

Blueberries are widespread group of perennial flowering plants, produces green berries that turn into bluish or purple hue when ripe. They are classified in the section Cyanococcus within the genus Vaccinium. Blueberry species of commercial importance include highbush blueberry (Vaccinium corymbosum) and lowbush blueberry (Vaccinium angustifolium). Blueberries are present in many parts of world, including North America, Europe and Asia with cooler climate.

Blueberries are an excellent source of dietary fibre, vitamin C, vitamin K, manganese, iron, and a number of antioxidants.

The major phytochemicals in blueberries are polyphenols, including anthocyanins, proanthocyanidins, other flavonoids, phenolic acids and stilbene derivatives.

1. Anti-diabetic Potential

Daily dietary supplementation with bioactive compound from blueberries improved insulin sensitivity over 6 weeks in obese, nondiabetic, and insulin-resistant participants. The bioactive compounds in blueberries enhanced insulin sensitivity independent of any changes in inflammatory biomarkers or adiposity.

Figure 1: Mean change in insulin sensitivity in the obese, insulin-resistant men and women who consumed either the blueberry or placebo smoothies for 6 wk. ∆ = postintervention − preintervention.

Values are means ± SEM, n = 15 (blueberry) or 17 (placebo).

2. Support Endothelial Function

Study showed that the mean change in resting endothelial function, expressed as reactive hyperemia index (RHI), was improved significantly more in the group consuming the blueberries versus the placebo group. Daily dietary consumption of blueberries improve endothelial function over six weeks in subjects with metabolic syndrome.

Figure 1: (A) Change in RHI (Δ; post- minus pre-intervention) in individual humans with metabolic syndrome who consumed the blueberry or placebo smoothie for six weeks; (B) mean change in RHI after adjusting for percentage of body fat and gender.

* p = 0.0023 between groups (blueberry versus placebo). RHI, reactive hyperemia index (i.e., endothelial function). Values are the means ± SEM, n = 22 (blueberry) or n = 18 (placebo).

Reduce Cholesterol

The antioxidants in blueberries have been shown to reduce a predominant risk factor for heart disease by preventing oxidative damage to “bad” LDL cholesterol.

Protect against Aging and Cancer

Blueberries are high in antioxidants, they can neutralize free radicals that cause damage to DNA, which is a leading driver of aging and cancer.

Maintain brain function and improve memory

The antioxidants in blueberries benefit brain by aiding brain function and delaying mental decline.
