近来，网上有消息称，美国科学家经过长期研究，发现人们常用蔬菜中，比如西红柿等蔬菜都含有数量不等的尼古丁。这些蔬菜如果未加烹饪而生吃，则进入人体的尼古丁数量会更多，由此而受到的伤害，会接近于烟雾弥漫中的被动吸烟。此消息一出，网友非常关注：生吃西红柿等蔬菜真的等于吸烟吗？那这些蔬菜都只能熟着吃了？日前，国家高级公共营养师程洋洋接受新华网记者的专访时表示，生吃西红柿不会对人体的健康产生危害。

recent，Online sources said，Scientists in the United States after long-term research，Find people in vegetables commonly used，Such as vegetables, such as tomatoes contain any number of nicotine。These vegetables if not add cooking and raw，Into the human body and the number of nicotine more，From this and hurting，Will close in smoky of passive smoking。The news a，Net friend is very concerned about the：Raw vegetables, such as tomatoes really equal to smoke？That these vegetables are only to eat well？a，The national senior public nutritionists ChengYangYang accept xinhua net reporter interview said，Raw tomatoes won't cause harm to human body health。

　　程洋洋介绍说，目前，我国的食品科学专家及教授在研究中还没有在西红柿里发现尼古丁这种物质，或者说尼古丁这种物质在西红柿里的含量非常少，很难被发现。所以说西红柿里面即使有这种物质，那也是含量极其微小，可以忽略不计，不会对我们的健康构成威胁。

ChengYangYang introduced said，At present，China's food science experts and professors in the study is not found in tomatoes nicotine the material，Or nicotine this substance in the content of the tomato is very little，Have been hard to find。So even if there is this kind of material in tomatoes，That is an extremely small content，negligible，Not poses a threat to our health。

　　那么，比起生吃，西红柿熟吃有哪些优缺点？哪些蔬菜不能生吃，或者说熟吃更营养？程洋洋说，相比于生吃西红柿，熟食的营养价值会略胜一筹。“因为在西红柿熟食时，具有抗氧化功能及具有抗癌作用的的番茄红素和对我们眼睛有益的胡萝卜素大量释放，提高了这些营养素在我们身体的吸收率。另外，由于维生素‘怕碱不怕酸’的特点，所以在熟食的过程中，维生素C的破坏程度不是很大，钾和膳食纤维也不会大量破坏了。”

so，Compared with the raw，What are the advantages and disadvantages eat cooked tomatoes？Which vegetables can't eaten raw，Eat more nutrition or cooked？ChengYangYang said，When compared to the raw tomatoes，Cooked food nutrition value will be slightly better。“Because in the tomato cooked food，With antioxidant function and has cancer-fighting of lycopene and to our eyes beneficial carotenoids a large release，Improve the nutrients in the absorptivity of our body。In addition，Because vitamin‘Afraid of alkali not afraid acid’Characteristics of，So in the process of cooked food，Vitamin C is not a very big damage，Potassium and dietary fiber also won't have destroyed a large number of......。”

　　程洋洋介绍，西红柿里面含有大量的维生素C，番茄红素，钾元素和大量的膳食纤维，口味酸甜，许多人都非常喜欢生吃，但是，我们在生吃的时候一定要根据自己身体的状况，看食用之后肚子会不会发凉，出现腹泻等这些不适的症状，如果没有这些问题，那么我们就可以把西红柿作为夏季减肥解渴的一种时令水果来生吃了。

ChengYangYang introduced，The tomato contains a lot of vitamin C，lycopene，Potassium element and amount of dietary fiber，Taste sweet and sour，Many people are very like raw，but，We must be eaten raw according to their own physical status，Look after eating stomach will not hair is cool，Occurrence diarrhoea, the symptoms of discomfort，Without these problems，Then we can put the tomatoes as summer reduces weight a thirst to raw fruit in season。

　　“我们经常听到学校学生因为吃了食堂没有做熟的蔬菜而发生恶心，呕吐，腹泻等症状。究其原因，是该校学生吃的是没有烹调熟透的豆角，因其含有皂甙和凝集素，这两种物质可致凝血和对胃肠产生一定的刺激，因此，在食用这类含有凝集素的蔬菜时一定要将其熟透。这类食物烧熟后，凝集素蛋白就会失去毒性，便可放心食用。除此之外，还有一些不宜生吃的蔬菜，如：土豆、山药、等富含淀粉的食物，还有叶菜在食用的时候也一定要用开水焯一下。”程洋洋对记者说。

“We often hear school students because ate dining room not cooked vegetables and nausea，vomiting，diarrhea。Investigate its reason，Is this school students to eat is no cooking squashy beans，Because of its contain saponins and lectin，These two kinds of material can cause blood coagulation and produce certain stimulation of gastrointestinal，so，In the edible such contains lectin vegetables will be sure to its is done。This kind of food and cooked，Lectin protein will lose toxicity，He can be safe to eat。In addition，And some unfavorable raw vegetables，if：potatoes、yam、Rich in starch food，And leafy vegetables in edible when also must use boiled water Chao once。”ChengYangYang told reporters。

　　此外，从营养学的角度，程洋洋也给了一些大家吃西红柿的建议，总的来说，西红柿在熟食的时候营养素的释放量更大，也利于人体的吸收，且在加热的过程中不会破坏各自营养素。如果你外出或者只希望摄取其中的维生素C，那么就可以选择几个洗干净的西红柿，食用安全方便又营养健康，既是水果又是蔬菜。“但是，如果是在家里面做饭，那么您最好将西红柿做熟来食用，这样就不仅可以摄取维生素C，还会摄取更多对我们身体有益的营养素。”(新华网记者 陶叶 姜春媛)

In addition，From the point of view of nutrition，ChengYangYang also gives some people eat tomatoes Suggestions，In general，Tomatoes in cooked food nutrients is released when more big，Also of the human body to absorb，And in the process of heating won't destroy their nutrients。If you go out or only hope of getting the vitamin C，So can choose a few clean tomatoes，Food safety for the convenience and nutrition and health，Fruits and vegetables is。“but，If is at home cooking，So you had better will be cooked tomatoes to eat，This not only can absorb vitamin C，Will absorb more of our body good of nutrients。”(Xinhua net reporter ceramic JiangChunYuan leaves)
