　　Thanks to the British love for coffee and tea, plant-based nut milks have experienced a huge increase in popularity.

　　感謝全球人民對於咖啡和茶的熱愛，代奶產品，如植物奶、堅果奶等在過去十幾年間的銷量實現了爆發式增長。

　　Milk consumption has dropped by 30 percent in the last 20 years, while one in five households has swapped cow's milk for an alternative.

　　與此同時，過去20年間，全球牛奶銷量下降了30%，將近1/5的消費者轉而選擇了代奶產品。

　　This is despite the fact that only five in every 100 people in the UK are estimated to have lactose intolerance.

　　僅在英國，就有超過5%的人被認爲患有乳糖不耐受症。

　　Growing numbers of cafes now offer the option of a nut milk with your latte, and, such is the demand, consumers can choose between almond, coconut, hemp, hazelnut, soy and cashew milks.

　　越來越多的咖啡廳開始提供堅果奶拿鐵，顧客則可以從杏仁奶、椰奶、大麻奶、榛子奶、豆奶、腰果奶中隨意挑選。

　　Despite warnings of early osteoporosis, the rise in dairy-free has been attributed to the belief that it improves digestion, reduces bloating, helps clear skin and lowers risk of cancer.

　　除可能導致早期骨質疏鬆症以外，人們普遍認爲代奶產品能夠促進消化，緩解腹脹，清理皮膚，還能預防癌症。

　　However, not all nut milks are created equal - and the ingredients in some could trigger health problems of their own.

　　但喜歡堅果奶的朋友們請注意了，並不是所有堅果奶都具有相同的健康功效，其中的有些種類還有可能給人體帶來健康隱患。

　　Indeed, a number contain sunflower oil as a hidden ingredient.

　　要知道，許多堅果奶都含有葵花籽油成分。

　　Kara Rosen, founder of PLENISH, said: "Sunflower oil has fallen out of favour with the medical and nutrition communities due to the level of omega-6, which has been linked to inflammation, heart disease and dementia.

　　PLENISH 創始人 Kara Rosen 表示：“葵花籽油的味道被其他成分所掩蓋，但其本身會導致發炎、心臟病和癡呆症等疾病。”

　　Indeed, research published last year in the British Medical Journal linked sunflower oil to higher rates of heart disease.

　　去年，《British Medical Journal》上刊登的一篇文章顯示，葵花籽油可能會增加人體患心臟病幾率。

　　Sunflower oil is used to bulk out the liquid, in order to reduce the number of nuts required.

　　在生產堅果奶時，人們經常會使用葵花籽油來擠出堅果中的多餘水分。

　　Rosen explained: "When I started to look at the category with the view of creating my own nut milk at PLENISH, all of the brands had a very low level of nuts - just one to two per cent - as well as a long list of additives like carrageenan, sunflower oil, guar and gellan gum, to name a few.

　　Rosen 解釋道：“經過調查我們發現，各大品牌的堅果奶中真正的堅果成分含量僅有不到1-2%，而其他成分，例如卡拉膠、葵花籽油、瓜爾膠、植物凝膠等的含量非常高。”

　　"Our research showed manufacturers did this to keep costs down - additives are much cheaper than nuts. But we made the decision to keep our levels of nuts high to boost nutrition."

　　“加入如此多的添加劑是爲了降低生產成本，這一做法無疑會大大降低堅果本身的健康功效。但在 PLENISH，我們始終堅持還原堅果最純最本的滋味。”

　　Alpro said the percentage of nuts used in their nut milks was based on customer taste. A spokesperson said: "One litre of our almond drink contains approximately 20 almonds, and a 200ml serving provides 30 per cent of a person's reccommended daily allownace of vitamin E."

　　PLENISH 公司產品中的堅果成分含量根據顧客口味偏好穩定。公司負責人曾表示：“1升PLENISH 杏仁奶中含有將近20顆杏仁，喝200毫升就能滿足成年人一天維他命E所需攝入量的30%。”

　　While omega-3 is key for great brain function - the omega-6 in sunflower oil is a little different.

　　和對大腦有益的 Omega-3 相比，葵花籽油中的 Omega-6 成分功效略有不同。

　　Rick Miller, registered clinical and sports dietitian and nutrition manager for a2 Milk, explained: "We cannot make omega-6 ourselves but derive it from plant sources in our diet such as sunflower oil, as well as bread, pasta, rice, potatoes, beans, peas and other vegetables.

　　註冊營養師 Rick Miller 表示：“我們自身無法產生 Omega-6，我們必須通過食物來攝取該成分，例如葵花籽油、麪包、麪條、米飯、土豆、豆類、蔬菜等。”

　　"We already tend to consume a lot of it in our normal diet, and research suggests too much may have a pro-inflammatory effect when we don't eat enough omega-3 - fatty acids that are anti-inflammatory - to balance it out."

　　“然而從正常飲食中，我們就已經能夠獲取足夠的 Omega-6了，研究顯示，如果該成分攝取過多，且沒有攝入足夠具有消炎功效的 Omega-3 脂肪酸來進行中和，就可能會導致炎症。”

　　If it's not even, we begin to impact on our health.

　　也就是說，這兩種成分如果攝入失衡，就可能會給人體帶來健康隱患。

　　Sandra Greenbank, a nutritionist, reccommended: "Consuming large amounts of foods containing sunflower oil or other omega-6 fats is unadvisable.

　　營養學家 Sandra Greenbank 表示：“不推薦過多攝入含有葵花籽油或 Omega-6 成分的食物。且普通堅果奶中的添加劑可能會給人體帶來額外損害，尤其是要額外注意糖分含量過高的堅果奶，建議選擇無糖堅果奶。”
