Now, oxygen-derived free radicals are considered respectable biochemi­ cal intermediates, given always the caveat that unwanted tissue damage may arise if these active species are produced in such abundance that they overwhelm the natural antioxidant and free­ radical defense mechanisms, or if these systems have become hypoeffective. Many factors, including several dietary manipula­ tions, can lead toelevatedproductionofsuperoxide and may result in free radical overload, whereas a deficiency of those micronutri­ ents associated with the antioxidant defense mec.hanisms may re­ sult in substantially diminished antioxidant capacity. By now, antioxidants have become a household word and al­ most everyone is aware of their imponance in protecting the body against attack by active oxygen species. Indeed, it is a paradox of nature that oxygen, which is so essential to sustain aerobic life, ul­ timately contributes to its destruction. Not surprisingly, recogni­ tion ofthis dilemma has generated a spate ofantioxidant strategies intended to reduce the risk of tissue damage by rampant oxygen radicals, some sadly based less on science than on speculation.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9781461267546\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9781461267546","offer_id":39415787618397,"sku":"9781461267546","price":160.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ed338ced-400a-4169-9ff5-85a401a9748c.jpg?v=1760587466","url":"https:\/\/shop.autorenwelt.de\/en\/products\/trace-elements-micronutrients-and-free-radicals-von-ivor-e-dreosti","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
