Blueberries as Antioxidants
What are oxidants? Oxidants are free radicals which are found either in our environment like cigarette smoke, air pollution or naturally produced in our bodies after viral or bacterial infections. Aging, cancers and cardiovascular diseases are results of accumulation of these oxidative substance. So, antioxidants are highly important.
Then, what are antioxidants components found in blueberries? Blueberries are rich in phyto derivatives, such as flavonoids and phenolic acid, these compounds play a very big role as antioxidants and anti-inflammatory, and it is proved that antioxidants are present on wild blueberries, and their level in blueberries are higher than those present in strawberries, cranberries, plums or others.

(leptin is a hormone which is responsible for energy consumption and feel of satisfaction).
2-Diabetes Mellitus
Flavonoids are compounds found richly on blueberries.
A follow-up study published in 2012 was aiming at determining whether dietary flavonoid intakes contribute to lower the risk of type 2 Diabetes Mellitus or not.
Researchers followed 3,645,585 persons for years and results showed that there is a significant association between the intake of rich-in-flavonoid food -especially blueberries- and a lower risk of type 2 Diabetes.

In (Osman et al., 2008), researchers discovered that blueberries’ intake decreases the bacterial and inflammatory reactions in the colon, which means that it can decrease colitis.
Blueberries and Your Brain
One of the most important functions in the brain is processing sensory information or cognitive function.
Cognitive functions are mental processes that allow us to do any task. They allow the subject to have an active role in the processes of receiving, choosing, transforming, storing, processing and retrieval of information, allowing the subject to react to the world around him.
However, as we grow older our brains tend to become less receptive to learning new information. By the age of 40, genes that are associated with learning and neuroplasticity tend to shut down. And by the time we reach the age of 65 or older, the chemicals in our brain begin to make dramatic changes, such as decreases in serotonin, dopamine, and glutamate, all which are important for healthy brain functioning. The grey matter in our brains also begins to thin.
As a result of these physical changes in the brain, many people experience age-related declines in cognitive ability. In addition, individuals 65 and older have a one in 8 chance of developing age-related dementia, such as Alzheimer’s disease, which severely inhibits your ability to think rationally, solve problems, learn new things, and form memories.
Researchers proved that one of the ways to protect your brain against aging processes is to add phytochemicals antioxidant-rich foods to your diets.
