Ｃｏｌｏｒ Ｃｏｄｅ食物中的顏色密碼

人類的皮膚透露了年齡，食物的顏色則透露了其營(yíng)養(yǎng)價(jià)值。想要為身體補(bǔ)充恰當(dāng)?shù)臓I(yíng)養(yǎng)，不必費(fèi)心去分析和記憶種類繁多的營(yíng)養(yǎng)成分表，只需按顏色進(jìn)行挑選，便能輕松達(dá)成所愿。

Everyone knows it's important to maintain a balanced diet if you want to live a long， active life. But sometimes figuring out which foods give you what nutrients can be tough. However， there is a foolproof1) method that makes getting- and staying-healthy that much simpler: Eat by color!

The key to eating by color is to understand the notion2) that each fruit or vegetable， whether it's blue， red， or green， is made up of a different combination of phytochemicals3). Phytochemicals are non-nutritive plant substances that have disease-prevention properties and give each piece of produce its specific color. Each of the color groups of foods offers different health benefits to the body. Therefore， by consuming a variety of foods in various colors， you are digesting the full range of nutrients needed to keep your body healthy. Take a look at the following seven color groups.

按照顏色選擇食物的關(guān)鍵是要理解一個(gè)概念，即每種水果或蔬菜，無(wú)論是藍(lán)色、紅色或綠色，都是由植物化學(xué)成分通過不同的排列組合而成的。植物化學(xué)成分是具有預(yù)防疾病功能的非營(yíng)養(yǎng)植物物質(zhì)，它們決定了每種食物的特定顏色。每種顏色系列的食物對(duì)人體的健康提供了不同的益處。因此，通過食用不同顏色的各種食物，你可以全面獲得保持身體健康所需的營(yíng)養(yǎng)?？纯匆韵缕呓M顏色不同的食物。按照顏色選擇食物比你可能預(yù)想到的更容易、更營(yíng)養(yǎng)。

Red fruits and veggies4) are loaded with lycopene5)， a natural pigment6) that aids in ridding the body of harmful bacteria that cause gene damage. Studies have shown that people who have a high amount of lycopene in their diet are less susceptible7) to heart and lung disease， and many forms of cancer. (Tip: The chemical form of lycopene found in tomatoes is more easily absorbed by the body if the tomatoes are cooked.)

紅色的水果和蔬菜含有番茄紅素，這種天然色素能夠幫助人體去除可能導(dǎo)致基因損害的有害細(xì)菌。研究顯示，攝入大量番茄紅素的人患心肺疾病和多種癌癥的幾率更小。(小竅門:番茄經(jīng)過烹飪后，所含的番茄紅素化合物更容易被人體吸收。)紅色系列的食物包括番茄、西瓜、紅甜椒和粉紅葡萄柚。

你媽媽是否曾經(jīng)告訴過你吃胡蘿卜對(duì)眼睛有好處?她說得沒錯(cuò)!橙色食物中最有益的營(yíng)養(yǎng)成分之一是β胡蘿卜素，它會(huì)轉(zhuǎn)化為維生素A。比如，胡蘿卜就是含β胡蘿卜素最豐富的食物之一。除了預(yù)防各種眼疾(白內(nèi)障、視網(wǎng)膜黃斑病變)和改善夜里看清東西的能力外，β胡蘿卜素還能幫助預(yù)防心血管疾病和癌癥。橙色系列的食物包括甘薯、芒果和冬南瓜。

橙黃色的食物富含維生素C和錳元素。這些營(yíng)養(yǎng)成分含有抗氧化劑，能夠增強(qiáng)人體的免疫系統(tǒng)，加強(qiáng)血管功能，幫助保持皮膚和牙齦健康。人體內(nèi)含有的維生素C越多，身體抵抗感染的能力就越強(qiáng)。橙黃色系列的食物包括菠蘿、橙子、黃甜椒和橙汁。

Foods in the white category include onions， cauliflower， and potatoes.

Blueberries rank No.1 in antioxidant properties when compared with 40 other fruits and vegetables. Blueberries and other purple/blue food items contain anthocyanin30)， which helps in preventing blood clots31) and delaying the aging of cells in the body. In recent studies， these phytochemicais also have been linked with delaying the onset of Alzheimer's disease32) by preserving brain and memory function. Foods in the purple/blue category include eggplant， blackberries， and prunes.

It's important to eat high-protein foods like meat and chicken too.

鱷梨和其他黃綠色食物富含鉀元素和蛋白質(zhì)。比如，青豌豆是除了利馬豆之外蛋白質(zhì)含量最高的新鮮食物。食用此類食物有助于降低患骨質(zhì)疏松癥、腎結(jié)石和高血壓等疾病的風(fēng)險(xiǎn)。黃色/綠色系列的食物包括黃玉米、蜜瓜和青豌豆。

綠色水果和蔬菜中維生素A、鈣和一種叫葉酸的維生素B派生物含量很高，是能量和抗癌營(yíng)養(yǎng)成分的絕佳來(lái)源。它們還含有葉黃素和玉米黃質(zhì)，這兩種植物營(yíng)養(yǎng)素對(duì)眼睛的健康至關(guān)重要。(小竅門:和番茄一樣，烹飪后的菠菜在某些方面比生菠菜更有營(yíng)養(yǎng)。)綠色系列的食物包括羽衣甘藍(lán)、球花甘藍(lán)、長(zhǎng)葉萵苣和球芽甘藍(lán)。

大蒜和其他蔥科植物中的蒜素含量豐富，這種植物化學(xué)成分能降低膽固醇和血壓。作為主要的抗細(xì)菌食物，大蒜能對(duì)抗從普通感冒到惡性腫瘤等多種健康問題。盡管白馬鈴薯中淀粉和碳水化合物的含量高，它們也含有鉀、煙酸、纖維和維生素B6等營(yíng)養(yǎng)成分，能提升體力水平和維持肌肉耐力。白色系列的食物包括大蒜、花椰菜和土豆。

和其他40種水果和蔬菜相比，藍(lán)莓在抗氧化性能方面位居第一。藍(lán)莓和其他藍(lán)紫色的食物含有花青素甙，這種成分有助于預(yù)防血栓，延緩體內(nèi)細(xì)胞衰老。近期的研究發(fā)現(xiàn)，這些植物化學(xué)成分通過保護(hù)大腦和記憶機(jī)能來(lái)延緩老年癡呆癥的發(fā)作。藍(lán)紫色系列的食物包括茄子、藍(lán)莓和李子干。

食用豬肉和雞肉等高蛋白食物也很重要。專家建議堅(jiān)持食用脂肪含量低的食物，如瘦肉、魚肉、家禽、無(wú)脂或低脂乳制品，以及雞蛋或蛋白。另外，很多素食品也能為人體成長(zhǎng)提供蛋白質(zhì)，如大豆蛋白粉和肉類替代品、豆腐、枝豆(日本大豆)、蠶豆、裂莢豌豆和小扁豆等。

The bottom line33) is that sprucing up34) your fish， poultry， or meat-based meals with colorful vegetables and fruits makes it look enticing and taste great too. The more colorful foods you consume， the healthier you will be. Bon appétit35)!
