“They also showed upregulated expression of cellular antioxidant defense system components that protect against oxidative stress. These findings suggest that sulforaphane from broccoli sprouts prevents age-related cognitive decline by maintaining mitochondrial function, thereby reducing oxidative stress in mice.”

“More evidence that sulforaphane (high in broccoli sprouts) may have positive effects on the brain. A pilot trial finds sulforaphane treatment increased glutathione levels (the body and brain's most abundant antioxidant) in the blood and hippocampus region of the brain in healthy people.”

“One enzyme, copper-zinc superoxide dismutase, neutralizes hydrogen peroxide radicals by accepting an electron at its copper site. By absorbing reactive oxygen species, antioxidant compounds prevent damage to structures such as lipid membranes, enzymes, and DNA.”

“One potential compound in mushrooms that may have brain benefits is ergothioneine. It is a unique antioxidant and anti-inflammatory compound that also accumulates in mitochondria. Humans are unable to synthesize ergothioneine on their own but it is present in a variety of mushrooms.”

“The one group of people that did not benefit from coffee consumption were pregnant women because it increased the risk of miscarriage. Many of the polyphenols found in coffee have been found to have anti-inflammatory and antioxidant activities.”

“Telomeres and how they relate to aging. How antioxidants prevent damage to DNA, lipid membranes, and proteins in the body. Supplemental vitamin E and the interaction between alpha and gamma tocopherols.”

“Olive oil contains monounsaturated fatty acids as well as a number of phenolic compounds that act as antioxidants, protecting the body from oxidative stress and inflammation. A growing number of studies demonstrate that olive oil may provide protection against cognitive decline.”

“The mechanism for the cognitive benefit is unclear and may include catechins, theaflavins, thearubigins and L-theanine which are all anti-inflammatory and have antioxidant activity. However, caffeine itself cannot be ruled out as a contributing factor as well.”

“01:32:25 - Debunking the claims that vitamins and antioxidants cause cancer. 01:36:05 - Randomized double-blind placebo-controlled trials are less effective for nutrition research due to differences in vitamin and drug status between study participants.”

“Sulforaphane exerts its therapeutic effects through a variety of mechanisms, the most notable of which is the activation of Nrf2, a cellular protein that regulates the expression of antioxidant and stress response proteins that provide protection against oxidative stress due to injury and inflammation.”
