Every year, Vietnam has about 200,000 people with pathological cerebral vascular accident, nearly half of them died. Free radicals are believed to cause cerebrovascular pathology and neuronal degeneration. So what should we do to prevent cerebral vascular accident?
Free radicals and cerebral vascular accident
Since 1990, studies the Global Burden of Disease (GBD) by the World Health Organization (WHO) has classified the cerebrovascular disease in second place in the list of top killers, just after illness heart. In HCMC, the statistics show that about 19,000 strokes each year, of which about 1,000 deaths.
There are many causes of cerebral vascular disease, in which the role of free radicals are increasingly concerned. Associate Professor Dr. Tran Dang, former Director of Food Safety and Hygiene, said: "Free radicals are harmful elements generated from the metabolism of the body and from the influence of external factors . they are considered modern medicine origin of aging and many diseases. "
Free radicals (free radicals) are atomic or molecular damage, continuously generated from the metabolism in the body and from the impact of the external environment. Free radicals are considered to be the origin of aging and disease. It is like "army destroyed" by the very strong damaging to the human body, especially the brain hurt.
Extracts from Blueberry OTIV help fight free radicals, protect blood vessels and brain neurons
Free radicals are very unstable, constant electronic search of atoms - molecules, creating new free radicals. Free radicals attack all cell structures in the body, and especially their "preferred" the fat cells (lipids). Featuring more than 60% of the fatty acid composition, the human brain is the body free radicals are the most violent attacks.
Moreover, while the system against free radicals less than other organs, the brain consumes up to 20-25% of energy demand and oxygen throughout the body. Where there is a higher metabolism, free radicals generated as much.
So the brain is really rallying free radicals and the chain reaction, "Army destroy" does not stop production, causing the disease: transient cerebral ischemia, cerebral vascular accident , migraine, dementia, Parkinson's, Alzheimer's, dementia ...
"No one is allowed subjective, because over time, the damage to blood vessels caused by free radicals almost inevitable" - Dr. Tran Dang said.
What to do to prevent cerebral vascular accident?
According to doctors, the anti-free radicals in herbs, vegetables ... can help protect the brain blood vessels and brain neurons. However, they can only be effective if cross the blood brain barrier - a barrier to control all biological substances into the brain.
Prof. Tran Dang also asserted: "Additional anti-free radical by nature is a good weapon to health care for the brain. Should however know that free radicals generated more if malnutrition , prolonged stress or living in polluted environments. "
So, according to him, maintain balanced diet, activity has rules, just strength athletes, keep the spirit of optimism, psychological balance and avoid harmful as tobacco, chemicals Herbicides - insect ... is absolutely necessary.
The scientists studied a North American berries are rich in anthocyanin Blueberry - anti-free radicals have been able to cross the blood brain barrier. These substances neutralize free radicals, inhibiting the oxidation of "bad" cholesterol, regulating inflammatory factors in order to reduce damage to blood vessels. We also affects nerve cells and synapses to help the brain against degeneration, injury recovery.
According to researchers at the University of Montreal (Canada), Blueberry trigger two protective enzymes catalase and superoxide dismutase brain. The function of this enzyme cleaning up free radicals produced during oxidation, reducing the risk of neurodegenerative and cerebrovascular disease.
