吃用自家煤火烤得玉米對身體有壞ma？

其實燒烤最大的問題不在于食物，而是加在食物上的油汁、醬料，這些油滴落在炭火上，加熱后會產生致癌物質，附在烤肉、烤豆干、烤玉米、烤魚等烤物上被吃入人體內，長期食用下來，致癌機率就會比較高一些。

此外，火焰還會使蛋白質產生化學變化，轉變成劇毒的致癌物質叫做異環(huán)胺（Heterocyclic amine），常常吃進這些物質，自然容易導致癌癥的發(fā)生。

為什么說烤肉會致癌？為什么那么多人還會去吃？

大家好，很高興能為大家解答?？救鈺掳┦且驗?1、在高溫狀態(tài)下，蛋白質已經變形.2、高溫燒烤過程會產生大量焦油，而它有強烈的致癌作用.3、燒烤是的肉類細胞內水分蒸發(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險大！

大多數(shù)人之所以選擇繼續(xù)吃，多是由于滿足于動物的本能，就好像小時候大家喜歡吃辣條一樣的！
