Ray Peat on antioxidants
"Altitude and a milk based diet are obviously two important thermogenic factors that slow the accumulation of harmful adaptations, but there are many other controllable factors that could extend longevity even more. Reducing inflammatory factors is important, and personal choices can make a big difference, for example choosing easily digestible foods to reduce endotoxin, avoiding the polyunsaturated fatty acids that interfere with cell respiration and form inflammatory prostaglandins, avoiding antioxidant supplements that create a reductive excess, and choosing foods that contain antiinflammatory-thermogenic compounds, such as citrus fruits with their high content of flavonoids that support cell respiratory functions."

The lower concentration of oxygen in tissues at high elevation would increase the antioxidant reserves of the organism, making it more resistant to stress. Decreasing the use of dietary unsaturated fats similarly protects against oxidative stress."

That view is being increasingly questioned, with the recognition of a reductive cellular state as a common factor in shock, stress, and degeneration."

When something interferes with the normal, productive use of oxygen, there is a great increase in the destructive forms of oxidation, such as lipid peroxidation, and the antioxidative reserves become crucial. That is, decreased respiration of the productive sort tends to increase the destructive use of oxygen."

0 upvotes"Vitamin A regulates Iysosomes, and so a deficiency might promote the accumulation of intracellular debris. It is an antioxidant, and so a deficiency might tend to induce the stress-hypoxia proteins, and it is used massively in the synthesis of steroids (for example, progesterone supplementation spares vitamin A). But possibly most important is the de-differentiation that occurs in many cells in a vitamin A deficiency. In the skin and mucous membranes, a vitamin A deficiency acts like an excess of estrogen, to promote the formation of keratin."

Copper is a component of the cytoplasmic SOD enzyme, which decreases with age. Ceruloplasmin, a major copper-containing protein, helps to keep iron in its safe oxidized form. Copper is involvedin the production of melanin (itself an antioxidant) and elastin. The loss of melanin, elastin, andrespiratory capacity, which s so characteristic of senescence, is also produced by excessive exposure to cortisol."

While it stimulates normal respiration it has an anti-inflammatory action, which probably involves both prostaglandin regulation and an antioxidant action. It is chemically very similar to our natural antioxidant, uric acid, and it raises the level of uric acid in both the blood"
