Abstract:
In the Rotterdam Study, the authors investigated whether high intake of antioxidants from food is associated with the risk of stroke. Among 5,197 participants who were followed on average for 6.4 years, 227 ischemic strokes occurred. Higher intake of antioxidants was associated with a lower risk of stroke. The relationship was dose-dependent, significant for vitamin C, and most pronounced in smokers. These results agree with the view that high dietary intake of antioxidants, in particular vitamin C and--in smokers--vitamin E, reduces the risk of stroke.

02:59Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
