In addition, dog food can be made to include nutrients especially designed to promote healthy intestinal bacteria. Dog food should also include antioxidants such as vitamin E and beta-carotene in order to promote immune health. Thus, it is relatively easy to improve the health of dogs by simply improving the nutritional quality of dog food. It is ironic that pet food is engineered according to research findings, while millions of children are being raised on junk food, and the elderly tend to eat a notoriously poor diet. Ways to slow down brain aging Lipoic acid was also discussed as an important means to slow down brain aging.
Brain diseases are the eighth leading cause of death.
Part of the pathology that is seen in cerebral aging is an increase in the levels of iron, together with a parallel decrease in tissue ascorbate. This leads to increased levels of free radicals in the brain tissue, and neural dysfunction and death. Other brain regions did not appear responsive to lipoic acid . This suggests that the forebrain, a region involved in cognition, has a special facility for the uptake and metabolism of lipoic acid. Lipoic acid's neuroprotective properties most likely comprise its ability to chelate free iron, in addition to its antioxidant effects, and the ability to regenerate ascorbate.
