營養師黃凱詩的生活點滴

黃詩詩解籤(二)之『如果我是生產商』

有時候無咩胃口,諗住用茄汁豆塗飯,可以剌激食慾啦!於是去超市掃貨,拿起個罐頭,反轉個背脊睇,嘩! 唔係啩! 營養師說這家牌子是健康選擇,幹嗎標籤寫上100克(整罐是230克的)已有熱量349『kcal』呢?一個菠蘿包也是360kcal,那麼吃一罐豈不是攝取803『kcal』。

有時都唔係好明白,營養標籤本來已是頗複雜的東西,幹嗎香港政府在立法時,又將簡單事情複雜化呢?何出此言? 將推行的營養標籤法,能量的單位是可以以千卡(kcal)或千焦耳(kj)表示,他們是兩個完全不同的單位,即是體重可以磅及公斤表示類同,但問題係,全香港,我相信有99.99999%的市民,都已慣常用卡路里去表示熱量單位的時候,又為何又容許多一個千焦耳呢?難道又想大家動動腦筋,做下心算麼?

唉...所以大家唯有記住1kcal = 4.2 kj,即是你下次見倒kj的時候,就要計一計,如上圖349/4.2是什麼了,所以以上圖的茄汁豆為例,100克應有83kcal,明白啦!

但係老老實實喇!就算政府俾生產商用兩種唔同的方法表示能量,『如果我是生產商!』,我都唔會咁傻用個大D嘅數字嚇D消費者架,你睇下下面兩個吞拿魚嘅標籤就會明。

上面那個,100克有100kcal,下面的,100克有466kj,消費者瞬間望過去,就會買上面個牌子囉! 見倒466喎,仲唔掉頭走咩!


下個星期再講!
