As a result, oxidative stress affects membrane properties such as fluidity, enzymes’ activities, ion transport, and cross-linking of proteins. The brain is particularly vulnerable to oxidative stress because it consumes 20% of the total body intake of oxygen , and it has limited antioxidant capacity and higher amounts of unsaturated lipids. MCI is considered an intermediate state between healthy aging and early dementia .
In humans, acute consumption of walnuts was reported to increase total antioxidant capacity and to reduce plasma lipid peroxidation . The components of walnuts, such as flavonoids, ellagic acid, gamma tocopherol, and melatonin, are known to have antioxidant and free-radical scavenging properties. Because components of walnuts have strong antioxidant properties, it is possible that the inhibition of Aβ-induced free radical levels by walnuts may be attributed to its effects on the neutralization of ROS. Recent animal and human studies from our and other groups have suggested that long-term dietary supplementation with walnuts may reduce the risk or delay the onset/progression of MCI and AD.
