Death By Peanut

Peanuts are one of the world’s most nutritious foods.

Peanuts contain pound for pound more protein, vitamins, and minerals than beef liver and more fat than heavy cream. For approximately .5% of Americans, however, peanuts are not so beneficial; in fact, they’re potentially deadly.

Yummy But Deadly

Between 1 and 2% of American adults suffer from food allergies. A food allergy occurs when particular proteins in certain foods trigger an immune system response, resulting in various symptoms. Many foods can cause allergic reactions ranging from mild to severe, but peanuts trigger notoriously fierce allergic responses.

People allergic to peanuts can experience hives, dizziness, a rapid heartbeat, and in the worst cases, death. Although only a small percentage of people have peanut allergies, they account for 50% of all food related deaths.

Usefulness

It may seem implausible that so much harm can result from such a seemingly innocent, useful food. However, it’s the peanut’s usefulness that makes it so dangerous. Peanuts and peanut products are used in a wide variety of packaged foods, but are not always listed as an ingredient.

Since it’s possible for even the slightest trace of peanut protein to trigger an allergic reaction, these hidden ingredients can cause considerable harm. In some cases, even kissing a person who’s just eaten a “peanuty” food can be dangerous.

If you have a peanut allergy never assume that foods are made without peanuts. Call the manufacturer and find out. Also, before you move in for a kiss, make sure that he or she is peanut free.

花生致死

花生是世界上最有營養(yǎng)的食品之一。

等重量的花生中蛋白質(zhì)、維他命和礦物質(zhì)的平均含量高于牛肝,而其脂肪含量高于多脂奶油。但是,大約有百分之五的美國人,對他們來說,花生不僅沒有好處,而且可能會致命。

美味但致命

大約百分之一到百分之二的美國成年人受到食物過敏癥的困擾。當一種特定食物中的特定蛋白質(zhì)刺激免疫系統(tǒng)作出反應并產(chǎn)生許多癥狀時,食物過敏就出現(xiàn)了。許多食物會導致過敏反應,輕重程度不等。但是花生能誘發(fā)非常嚴重的過敏反應。

人們對花生過敏時會產(chǎn)生蕁麻疹,頭暈,心跳加快等癥狀,嚴重時可能死亡。盡管對花生過敏的人群比例很小,但他們因過敏而死亡的人數(shù)卻占所有因食物而死亡人數(shù)的一半。

功效

讓人難以置信的是,如此多的危害會來自這樣一種看起來很無害、有益健康的食物。不過,正是花生的這種好處讓它變得很危險?;ㄉ盎ㄉ庸な称繁粡V泛制成袋裝食品,但不總是被列入成分表。

因為有可能很少量的花生蛋白就可以誘發(fā)過敏反應,這些成分如果不寫明,可能帶來嚴重危害。有時,甚至親吻一名剛吃了花生食品的人也會帶來危險。

如果您對花生過敏,千萬不要想當然認為您吃的食物中不含花生的成分。最好打電話給廠家確定一下。同時,在您同愛人親吻的時候,記得先確定他/她當時沒吃過花生。
