哪位大大能帮我翻译一下这段英文 语句要通顺的 不要网上的翻译 那都是骗人的！！！！！

so what is a trans fat really? 那么到底什么是反式脂肪呢?
a trans fat is a liquid fat that is turned into a solid. although there is a very small amount of natural trans fats in meat and dairy products,most of them are created by adding hydrogen to liquid fat其实反式脂肪是由液态脂肪凝固成固体的脂肪。然而天然存在于肉类和乳制品中的反式脂肪的数量是极少的，其中大部分都是在液体脂肪中加入氢而人工制成的。
food-makers do this because it makes the product last longer on the shelf.食品加工企业这么做,是因为这使产品在货架上的保鲜时间更长。
have you ever wonderd why cookies can still be crispy and "tasty" after six months to a year on a store shelf? it is because of trans of trans fats.你知不知道曲奇饼摆在货架上六个月到一年，仍旧保持又脆又好吃的原因？其实这就是反式脂肪的功劳了。
trans fats are typically found in things like donuts, french fries, cookies, microwave popcorn, and potato chips.反式脂肪广泛存在于甜甜圈、薯条、饼干、微波爆米花和薯片这类食品中。

希望对你有所帮助！！！！
