吃用自家煤火烤得玉米對身體有壞ma？

其實(shí)燒烤最大的問(wèn)題不在于食物，而是加在食物上的油汁、醬料，這些油滴落在炭火上，加熱后會(huì )產(chǎn)生致癌物質(zhì)，附在烤肉、烤豆干、烤玉米、烤魚(yú)等烤物上被吃入人體內，長(cháng)期食用下來(lái)，致癌機率就會(huì )比較高一些。

此外，火焰還會(huì )使蛋白質(zhì)產(chǎn)生化學(xué)變化，轉變成劇毒的致癌物質(zhì)叫做異環(huán)胺（Heterocyclic amine），常常吃進(jìn)這些物質(zhì)，自然容易導致癌癥的發(fā)生。

為什么說(shuō)烤肉會(huì )致癌？為什么那么多人還會(huì )去吃？

大家好，很高興能為大家解答?？救鈺?huì )致癌是因為:1、在高溫狀態(tài)下，蛋白質(zhì)已經(jīng)變形.2、高溫燒烤過(guò)程會(huì )產(chǎn)生大量焦油，而它有強烈的致癌作用.3、燒烤是的肉類(lèi)細胞內水分蒸發(fā)，剩下食入后在人體內大量吸收水分，破壞了人體正常的酸堿平衡、正常的水分代謝及血液循環(huán).因此總體而言致癌風(fēng)險大！

大多數人之所以選擇繼續吃，多是由于滿(mǎn)足于動(dòng)物的本能，就好像小時(shí)候大家喜歡吃辣條一樣的！
