As we mentioned in part I, strokes are caused by uncontrolled diet that is high in saturated and trans fats as a result of bad cholesterol building up in the blood vessels that block the circulation of blood to the body including the brain. If oxygen is not delivered to the brain cells, some cells die off and can not reproduce, then you may get a stroke. Other happen when a blood vessel in the brain ruptures causing the cells in your brain deprived of oxygen.
There are 2 types of strokes:
1. Ischemic stroke caused by a clot or other blockage within an artery leading to the brain.
2. Hemorrhagic stroke caused by the vessel in the brain rupturing in result of blood leaking into the brain.
1. Ischemic stroke This is the most common type of stroke accounting for almost 80 of all strokes. The most common problem is narrowing off the arteries in the neck or head.
b) If blood clotted in other parts of the body's arteries subsequently entering the brain, we have embolic stroke. In this case the clot was formed somewhere other than in the brain itself. The clot then travels the bloodstream until they become lodged and can not travel any further. This naturally restricts the flow of blood to the brain and results in embolic stoke.
2. Hemorrhagic stroke Hemorrhagic stroke occurs when a blood vessel bursts inside the brain, causing an increase of the fluid pressure on the brain and harms the brain by pressing it against the skull. Hemorrhagic stroke is associated with high blood pressure, which stresses the arterial walls until they break.

As we mentioned in previous articles, stroke is caused by uncontrolled diet that is high in saturated and trans fats resulting in cholesterol building up in the blood vessel in the brain that block the circulation of blood to the body, including cells in the brain. If not enough oxygen is delivered to the brain cells, some cells die off and can not reproduce, the you may have a stroke. Other strokes happen when a blood vessel in the brain ruptures causing the cells in your brain to be deprived of oxygen, thus they die and can never come back. Nutritional supplements have played an important role for nutritionally deficient patients in preventing stroke and here are are some of them:
1. B-complex Three B-vitamins: folate, B-6, and B-12 can lower homocysteine, an amino acid that is found naturally in the body and study shows that the higher the level of homocysteine in the blood, the higher the risk of stroke.
2. Beta-carotene Beta-carotene is an antioxidant that may reduce oxidative stress to brain cells. Such stress occurs when highly volatile forms of oxygen damage cell structure. Study shows that beta- carotene helps to reduce the risk against cerebral infraction and stroke.
3. Vitamin E Vitamin E is an antioxidant that helps to reduce arterial clotting.
4. Selenium Selenium is a powerful agent that helps to keep tissues and arteries elastic. It also helps to reduce the stickiness of the blood and decreases the risk of clotting, in turn lowering the risk of heart attack and stroke. Selenium increases the ratio of HDL (good) cholesterol to LDL (bad) cholesterol.
5. Pycnogenol Pycnogenol helps to keep collagen elastic and soften the blood platelets, making blood flow more efficiently.
6. Co enzyme Q-10 Co enzyme is a strong antioxidant that not only protects low density lipoprotein LDL against oxidants, but also helps for getting oxygen to the cells.
7. Lecithin Lecithin is a fat-like substance called a phospholipid that helps to remove bad cholesterol and other lipids from the body. It also protects the arteries and organs from the build up of fatty tissue that can lead to stroke or heart attack.
8. Melatonin Melatonin is a neurohormone produced in our body by the pineal gland. It is a powerful antioxidant that easily penetrates the blood-brain barrier and is used to treat thrombotic stroke.
9. Vitamin C Vitamin C helps to strengthen the arterial wall, lowering the risk of heart diseases and stroke.
