When they are produced, oxidative stress occurs through the mentioned targets.

Oxidative stress can overwhelm the mitochondria of all cells (including the liver), making it difficult for them to function — since the mitochondria produce energy for the cells.

if stearic acid in cacao is healthy why would stearic acid in lard harm us, plants and animals produce the most saturated fat that will melt at their body temperatures, to reduce oxidative stress.

The results showed that zinc and chromium can reduce oxidative stress to the same degree but the combination of both minerals produced better results.

Ketones produce far less oxidative stress when turned into energy when compared to glucose.

CoQ10 administration has been shown to reduce production of ROS by mitochondria exposed to Aβ in animal models of diabetes.18 With the AD brain struggling to produce energy and under great oxidative stress, CoQ10 could be a powerful adjunct.

Third, the brain could be redirecting its metabolic machinery toward utilization of fuels other than glucose, such as fatty acids and ketone bodies, which produce less oxidative stress and are, in fact, more efficient fuels.14, 46,47

They produce free - radicals which then go on to induce oxidative stress in cells and tissues throughout the body, and they strain and degrade the function of the liver, one of the body's most important detoxifying mechanisms.1

Lipoic acid protects the mitochondria, the energy producing factories of cells, from oxidative stress and toxicity like nothing else (9).

While our bodies are adept at producing antioxidants that balance the effects of oxidative stress, that ability lessens as we age and our skin — already compromised by the above assaults — produces less of the antioxidant - rich oils that protect it.

A free radical is a molecule produced in the body that lacks an electron which scavenges the body, taking electrons from structures which wouldn't otherwise give them away and causing oxidative stress.

It is well known that the mitochondria of cancer cells are damaged, producing massive amounts of waste products, oxidative stress, and contributing to inflammation.

Similar to the physical and cellular burn of exercise that creates some oxidizing free radicals, the «stress» from cruciferous vegetables stimulates our mitochondria to produce homemade antioxidants to counterbalance the oxidation and protect our vital DNA.28 Even cancer cells have caught on to this central role of our mitochondria — the bastards can amplify their levels of some of these same pathways — further stressing their importance for survival.25 However, our cells still seem to have the upper hand, as multiple studies show that the organosulfur chemicals in many of these anticancer vegetables can severely stress cancer cells, leading to oxidative damage, and ultimately, death.29
