<span style=color:#0000FF>青番茄：</span> 因含有龙葵硷，对胃肠黏膜有较强的刺激作用，对中枢神经有麻痹作用，会引起呕吐、头晕、流涎等症状，生食危害更大。
<span style=color:#00FFFF>无根豆芽：</span> 目前市场上出售的无根豆芽多数是以激素和对化肥生发的，这类含氮化合物在肠道细菌的作用下，会转化为亚硝胺，长期食用可使人患胃癌、肝癌、食道癌、直肠癌等。
<span style=color:#00FFFF>没煮熟的四季豆</span> ：如食用没煮熟的四季豆，或外表是青色的菜豆，便会中毒，导致头昏、呕吐，严重者甚至致人死亡。
<span style=color:#F0FFFF>发芽和变青的土豆</span> ；这类土豆与青番茄一样，含有龙葵硷，因此不应食用。
<span style=color:#00CED1>新鲜黄花菜：</span> 集市上的鲜黄花菜虽然新鲜，但因含有水仙硷，进入人体后，经氧化作用使人出现腹痛、腹泻、呕吐等中毒症状。若将新鲜黄花菜在水中充分浸泡，使水仙硷最大限度地溶于水，便不会产生上述症状。
<span style=color:#6495ED>变色的紫菜；</span> 若凉水浸泡后的紫菜呈蓝紫色，说明该菜在干燥、包装前已被有毒物所污染，这种紫菜对人体有害，不能食用。 |
