Through this and other pathways, some genes are expressed which are supposed to increase survival, so overall there is a window of free raficals concentration. If you get below it (total blockade) you will prevent the hormesis (beneficial) effect, but if you get above it, you can get all the free radical related diseases e.g neurodegenerative diseases.&lt;p&gt;[0] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;doi.org&amp;#x2F;10.1038&amp;#x2F;nm.3624&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;doi.org&amp;#x2F;10.1038&amp;#x2F;nm.3624&lt;/a&gt;</text></comment>

despite their antioxidant content and possibly due to other bio-active compounds. However, it should be noted that the current study applied comparably high doses of oral antioxidants, which have been tested in healthy young men only.</text></comment>
