A pure blueberry or other food products which contain blueberries has numerous health beneficial effects. Many researches were done on blueberries and proved that it is a powerful highest antioxidant fruit, which helps to get rid of many diseases. Antioxidants work by prevention of damage to the DNA of the cell and other structures by free radicals. Blueberries grew in North America, South America, Australia and New Zealand. Its size is approx 0.20 to 0.63 inches in diameter. Its one end contains crown shapes flare. When this fruit become mature, it will become sweet in taste. It is available in the market as fresh fruit, juices, puree, and as dried powder. In one popularity research, blueberry is the second most berries that widely used in all over the world.
It contains nutrients like anthocyanins, hydroxycinnamic acid, hydroxybenzoic acid, flavonols, and other phenol related micronutrients which are useful to boost immunity. These nutrients are worked as antioxidants and anti-inflammatory agents in our body. It also gives nutrients like vitamin K, manganese, vitamin C, fiber and copper.
Beneficial effects of blueberries
Consumption of blueberries provides many healthy effects to cardiovascular symptoms through many ways. One research has already proved that blueberries decrease the risk of heart attack in both male and female as it contains anthocyanins. Anthocyanins reduces the chance of plaque formation into smaller arteries and a vein through decreases the oxidative damage and inflammation of the heart tissue. It decreases the platelet function which is responsible for coagulation. It also improves the strength of vascular muscles which is situated in the wall of great vessels. It protects the vein, such as umbilical vein from oxidative damage through inhibition of peroxynitrite. It increases the good fat such as HDL and decreases the bad fat, such as triglyceride and LDL that responsible for atherosclerosis and heart attack in our body. Moreover, nitric oxide is formed due to oxidative stress and it increases the permeability of the vessels leads to more amount of cytokines enters into the vessels which serves as pre inflammatory agents. Anthocyanins induce inhibition of these agents by increases activation of monocyte macrophage system which destroys this agent and reduces damage and inflammation.
Effect on mental health
One research shows that consumption two cups of blueberry daily for four weeks improves cognitive function associated with the aging process as well as memory and dementia. Neuro degeneration occurs as age advances lead to loss of memory. Blueberries provide protection to the nerve cell body. Nerve cell body is very sensitive to oxidative stress and it needs full protection during the whole life span. Antioxidants reduce the damage from free radicals and provide protection to ner
ve cells. Anthocyanins enter into brain parts such as cerebral cortex part hippocampus, which is responsible for cognitive function. Anthocyanins also enhance the accessibility of neural signals to brain.
Reduces the glycemic index
A person with insulin resistance and type 2 diabetes mellitus finds difficulties to balance the blood sugar level in blood. It enhances the sensitivity of the insulin to digest the blood sugar. It enhances the uptake of blood sugars by skeletal muscle. It also improves the protein synthesis in the pathway of production of insulin. So, this way blue berry is responsible for low glycemic index between 40 and 50.
