Nutrition is Circulation | Betaine lowers homocysteine
Ischemia (low blood flow) and Apoptosis
Circulation of the blood is obviously vital for good health. What is not so obvious is that low blood flow (ischemia) can cause peroxidative damage and provoke programmed cell death by a mechanism called apoptosis. Apoptosis is the most common agent of aging because other mechanisms, such as peroxidation, glycosylation, protein cross-linking, DNA damage and nutrient deficiency, are more likely to damage but not kill the cell. Ischemia is a silent cause of aging: it kills cells in relatively small numbers, reduces their number, and gradually weakens tissue function. This is a progressive process, one that accelerates as the damaged and weakened tissues become ever more vulnerable.
