利记网上What, if anything, do we gain by clinging to our antioxidant supplements?
Very little, according to an accumulating body of research. We don’t need massive doses of antioxidants, we need stress to compel our own bodies to create antioxidants. “Everybody thinks oxidation is bad, and that antioxidants are good,” says Dr. Jones, “That’s bogus. A little bit of poison is good.”
That poison can actually come from plants, especially those that have survived harsh conditions. Foods that have survived harsh conditions make us stronger by stressing our bodies, not because they’re rich in antioxidants.
As the science quarterly Nautilus explains, plants have developed an arsenal of chemicals to help them ward off insects and grazers. These “antifeedants,” when ingested by humans, trigger the body to release proteins and activate genes that “produce antioxidants, enzymes to metabolize toxins, proteins to flush out heavy metals, and factors that enhance tumor suppression.”
Plants prepare your body to handle toxins much as exercise prepares you to race — by stressing your body. And supplements, says Dr. Hooper, interrupt this process.
利记网上“These antioxidant supplements are like a Trojan horse,” continues Dr. Hooper. “They say, I’m a good guy. You guys go to sleep and while the defense is asleep the antioxidants get rid of any oxidation. It puts the defense-system’s army to sleep.”
利记网上While Dr. Hooper acknowledges the benefits of vitamin E for muscle cramps and macular degeneration, he doesn’t approve the idea that it improves one’s physical performance. He suggests that athletes in intense contact sports such as soccer and football benefit from trauma. “Players have to be hit with pads on Tuesdays and Thursdays in order to compete on Sundays — they need that actual trauma,” he says.
“Everything in our society is geared toward, ‘How can we reduce stress?’” adds Dr. Hooper. “Then it should be just the opposite. We need stress. Stress is good.”
