This is the first study to show that the vital brain rejuvenation compound, BDNF1, can be elevated by a 1 year walking program of 40 minutes three times per week. The elevation of BDNF reversed the typical age-associated brain shrinkage and actually added 2% in size to the key memory center in the brain called the hippocampus.

This study is very good news since many older individuals are not physically able to do more intense aerobics that has previously been proven to elevate BDNF and brain rejuvenation. Elevating BDNF with exercise and BDNF-boosting nutrients like pantethine, DHA, blueberries, curcumin, zinc offer an excellent strategy to keep your brain healthy. In addition, optimizing thyroid function is key. Boosting BDNF levels will also help you lose weight, as BDNF is typically depressed in overweight people. Overweight people are known to have more cognitive decline than normal-weight people.
