今天咱来聊聊无谷狗粮是什么,无谷狗粮好不好,一篇文章将无谷粮介绍得明明白白!

01 无谷狗粮诞生记

2007年2月,美国各地的动物医院,在短短几周内陆续接收了多只奄奄一息的狗狗,它们的主人表示狗狗不吃不喝、浑身乏力,但是无法回忆起自己做过任何不对的行为导致狗狗病危。

经过检查,医生得出了惊人一致的结论——这些小狗的肾脏都出了问题,有些得了肾衰竭,会导致死亡。

让人难过的是,这样的意外死亡竟然迅速增多。随即,宠物家长们都意识到了问题的严重性,这件事也获得了全国的关注。大家也开始把怀疑的焦点,放在狗狗的日常饮食上——狗粮

2007年3月,出现第一家公开提出召回的狗粮厂商——加拿大Menu。

随后的几周之内,又有几十家狗粮品牌召回了自己的产品。最后这个数字去到了109,让这一系列事件成为了美国有史以来最大的狗粮召回事件。

所有相关狗粮厂商都开始追根溯源,到底是什么问题导致了大大小小的狗粮商同时陷入巨大的食品安全危机?甚至差点颠覆美国整个狗粮行业?最后的结果让人咋舌:

来自徐州和滨州的两家生物科技公司,为了提高出口小麦中可检测的蛋白质含量(氮检测法的原理有兴趣的朋友可以百度),添加了一种叫「Melamine」的物质。而「Melamine」这种物质,引起了狗狗的肾衰竭及死亡。

那么,「Melamine」是什么呢?相信我们中国的任何一个消费者都绝对不会陌生,它就是:三聚氰胺

当时如果中国食品行业能够重视这起事件,积极自查的话,可能一年后,也就是2008年,在国内引起轩然大波的三鹿奶粉导致大量婴儿肾结石的事件就不会发生。

回到美国的狗粮市场,自2007年的毒狗粮事件起,美国的消费者完全被吓到了——他们患上了谷物恐惧症,谈谷色变。而美国厂商利用这个商机,将高端狗粮与无谷粮画上等号。每一款高端狗粮包装上都赫然写着GRAIN FREE(无谷)。

02 矫枉过正的开始

2007至2017的十年内,中国宠物市场迎来了每年超30%的高速增长。越来越多的狗狗走进了我们的家庭。养狗也从一件粗糙随意的事,慢慢变成了可以和养育孩子媲美的头等大事。

铲屎官们每天辛苦挣钱的同时,也在搜寻着最合适自己主子的口粮。然而,在众多选择中,国产的狗粮厂商迟迟无法交出一份满意的答卷,甚至曝出各种斑斑劣迹的丑闻。

无奈的消费者不得不在进口狗粮中寻求更好的选择。找来找去,找到所有的高端狗粮都叫无谷粮。于是,一个深刻又错误的概念烙印在心——好的狗粮应该是无谷的。

我们既然从文章开头了解了始末,就不能直接对谷物一棒子打死,毕竟,错的是三聚氰胺,谷物是无辜的。那么,我们到底应该怎么看待无谷粮?它们好不好呢?

03 无谷 = 优质?

其实如果仅仅从字面意思来看,我们中国人所称的广义的谷类包括禾谷类、豆类和薯类。而英语中GRAIN一词指的就是禾谷类,也就是通常说的大米、小麦之类的谷物。

因此,无谷并不代表没有任何豆类或者薯类,而是

「无谷」= 不含「禾谷类」作物

包括小麦、大米、玉米、高粱等等。

Diss谷物的根源前文已经解释过了,就是2007年的美国毒狗粮事件。于是,有许多厂家都开始借机宣传无谷粮的好处,以此谋利。

我们针对几点常见的说辞,一一进行反驳:

狗狗不能消化谷物?

答:完全错误,狗狗完全可以消化谷物。

尽管仍然存在争论,但是狗目前在科学界仍然被界定为杂食性动物。并且与人类长时间的共同生活中,狗已经部分适应了人类提供的饮食。

再者,谷物的消化即多糖的消化是各个营养元素中最容易的环节了。即便是完全肉食性动物,猫,也能轻易消化谷物,不然你是如何看到那些吃高含量谷物粮的猫越长越胖的?因为吸收了呀!

狗不需要碳水,只需要肉?

答:完全错误,碳水化合物对狗狗而言是很重要的能量来源。

碳水化合物的吸收和释放的速度远远快于蛋白质和脂肪。作为能量来说,负担轻,消化成本低,绝对是必不可少的。所以宣称狗不需要碳水化合物的观点都是耍流氓。

狗容易对谷物过敏?

答:存在偏见

引起过敏的数据,谷物中只有小麦的排名靠前,并且,其实牛肉才是排名第一的。

以下是美国犬业联盟AKC给出的排名前五过敏食物源: beef 牛肉、dairy 牛奶、 wheat 小麦、 chicken 鸡肉、 egg 鸡蛋。

所以如果你的狗对什么食物过敏就请避开对应过敏源,完全不必把这桶脏水泼向所有谷物。

吃谷物会得糖尿病?

答:存在偏见

虽然多吃谷物的确会得糖尿病,我也强烈diss那些以谷物代替肉类作为主要材料的狗粮,但是市面上绝大多数的狗粮都是以肉类为主的,没有必要在这个角度走极端路线,一点谷物都不吃。

另外,请带你们加狗狗多出去运动运动,糖尿病的根本原因就是长期吃了超出身体消耗所需的碳水化合物。这是一个减法,减号的前面是摄入,减号的后面是消耗,双管齐下才健康。充分运动的狗狗患糖尿病的风险是极低的。

综上所述,「无谷」并没有其所说的各项优点,其中很多不单单是偏见,更是毫无根据的误导。

因此:无谷 ≠ 优质

04 无谷粮的缺点

其实,无谷粮不仅没什么优势,从有些角度看,甚至还有缺点:缺点就是又贵又浪费

首先,大部分无谷粮的主要蛋白质来源为肉类,因此,它们的价格普遍偏贵。贵没有错,但是毫无必要的贵就没有意义了!

petMD建议普通狗狗每天蛋白质的摄入应当为18% – 25%。然而,大量无谷粮的蛋白质高达40%。

如果你家的狗是狗狗中的孙杨,每天要进行大量的训练或者比赛,那毫无疑问,他需要摄入的蛋白质远远超过普通狗狗。

但是如果你家的狗只是狗狗中的葛优,每天只需要躺在沙发上看看电视就好了,那高蛋白的饮食毫无疑问是浪费的,甚至加重了身体的负担。

最后,即使是那么高的蛋白质比例中,有些也是根本无用的。无谷粮可以不添加谷物,但是不能不添加碳水化合物,因为那是狗狗必须的。于是,他们的解决办法就是增加豆类。

豆类中同时含有大量的蛋白质。然而蛋白质是由氨基酸组成的。每一次消化,就是把各种蛋白质分解成各种氨基酸,然后身体再根据需求把氨基酸来合成新的蛋白质。

但合成的过程就像搓麻将,必须有一定的氨基酸组合才能最终胡牌(合成一个需要的蛋白质)。比如谷物类植物缺少赖氨酸,而豆类植物缺少蛋氨酸。不过如果谷物和豆类组合在一起,配比就很合理,也依然可以合成所需要的蛋白质。

这就是为什么印度人的素食主义者比较多,因为他们的主要饮食是以扁豆加米饭为主,这个合理的氨基酸配比正好可以弥补原本在肉类里才可以获得的。

因此,如果无谷粮里只有豆类,而缺了谷物类,那其中的植物蛋白的吸收率就一定大打折扣了。所以我建议,即使吃无谷粮,也人为地添加一些谷物喂养。

但是,问题来了:如果要添加谷物,我们为什么还要吃无谷粮呢?

最后为大家奉献上AKC关于「狗狗能不能吃谷物小麦」的文章。标题还特地单独提了「小麦」,可见美国家长们看到小麦是有多么地恐慌了。结尾关于买无谷粮是不是浪费钱的措辞极为有趣:

如果你家狗狗吃谷物并不过敏,那也许买无谷粮是浪费钱的。但是如果你能负担得起无谷粮并且你家狗狗吃了身体也没什么问题,那就吃吧。

总之,无谷粮对谷物过敏的狗狗是有好处的,如果不,也许买无谷粮是浪费钱的!
