饮食与健康英语 (Food and Health Vocabulary)
omega-3 fatty acids
英文解释： Omega-3 fatty acids (omega-3s) are polyunsaturated fats that perform important functions in your body. Your body can’t produce the amount of omega-3s you need to survive. So, omega-3 fatty acids are essential nutrients, meaning you need to get them from the foods you eat.
中文解释：指“Omega-3脂肪酸”。Omega-3脂肪酸是一种多不饱和脂肪，对你的身体有重要的作用。你的身体无法产生维持生存所需的omega-3脂肪酸。所以，omega-3脂肪酸是必需营养素，这意味着你需要从你吃的食物中获取它们。
举例: Omega-3 fatty acids are “healthy fats” that may support your heart health. One key benefit is helping to lower your triglycerides. Specific types of omega-3s include DHA and EPA (found in seafood) and ALA (found in plants). Some foods that can help you add omega-3s to your diet include fatty fish (like salmon and mackerel), flaxseed and chia seeds.
Omega-3脂肪酸是“健康脂肪”，可以促进心脏健康。一个关键的好处是帮助降低你的甘油三酯(triglycerides)。特定类型的omega-3包括DHA和EPA(在海鲜中发现)和ALA(在植物中发现)。一些食物可以帮助你在饮食中添加omega-3脂肪酸，包括富含脂肪的鱼(如三文鱼和鲭鱼)、亚麻籽和奇亚籽。
beta carotene
英文解释：Beta-carotene [ˌbiːtə ˈkærətiːn] is a type of substance called a carotenoid. Carotenoids give plants, such as carrots, sweet potatoes, and apricots, their reddish-violet colors. Beta-carotene is a provitamin. This means it’s used by your body to make vitamin A. Provitamin A is only found in plants.
中文解释：指“β–胡萝卜素”。胡萝卜素（Carotenoids）为主要的维生素A源物质，主要有α、β、γ三种形式，其中最为重要的为β-胡萝卜素。胡萝卜素在我们身体里用来制造维生素A。维生素A原只存在于植物中。
举例：Beta carotene is a nutrient found in plants. It functions as provitamin A, which means it can be converted into vitamin A in your body.
Beta carotene is found in oranges and vegetables such as carrots, spinach, and sweet potatoes. Sweet potatoes are an excellent source — one 1/2-cup (100-gram) serving of baked sweet potato contains enough beta carotene to provide more than six times the DV of vitamin A.
β–胡萝卜素是植物中的一种营养物质。它的功能是维生素A原，这意味着它可以在你的体内转化为维生素A。
β–-胡萝卜素存在于橙子和蔬菜中，如胡萝卜、菠菜和红薯。红薯是一个很好的来源——一份1/2杯(100克)的烤红薯含有足够的-胡萝卜素，可以提供每日所以的6倍多的维生素A 。
lutein
英文解释： Lutein /ˈluːtin/ is an antioxidant that occurs naturally. It protects and improves eye function. It is part of a group of substances called carotenoids. Lutein and other carotenoids, such as zeaxanthin, may help prevent or slow macular degeneration. This is an eye disease.
中文解释：指“叶黄素”。叶黄素是一种天然的抗氧化剂。它保护和改善眼睛功能。它是胡萝卜素物质的一部分。许多人认为叶黄素是“眼部维生素”。叶黄素是在人眼(黄斑和视网膜)中发现的两种主要类胡萝卜素之一。它被认为起到滤光器的作用，保护眼睛组织免受阳光的伤害。富含叶黄素的食物包括蛋黄、菠菜、羽衣甘蓝、玉米、橙椒、猕猴桃、葡萄、西葫芦和南瓜。
举例：Broccoli is full of many vitamins and minerals important for skin health, including zinc, vitamin A, and vitamin C. It also contains lutein, a carotenoid that works like beta carotene. Lutein helps protect your skin from oxidative damage, which can cause your skin to become dry and wrinkled.
西兰花富含多种维生素和矿物质，对皮肤健康很重要，包括锌、维生素A和维生素C。它还含有叶黄素，一种类似于β -胡萝卜素的类胡萝卜素。叶黄素有助于保护皮肤免受氧化损伤，氧化损伤会导致皮肤干燥和皱纹。
Sulforaphane
英文解释：Sulforaphane is a chemical that is made when chewing cruciferous vegetables such as broccoli, cauliflower, and broccoli sprouts. A chemical in these vegetables called glucoraphanin mixes with an enzyme in humans called myrosinase, which produces sulforaphane.
中文解释： 指“萝卜硫素”。”萝卜硫素又称“莱菔硫烷”，在西兰花、芥蓝、花菜等十字花科植物中含有大量萝卜硫素的前体物质——萝卜硫苷，它可经植物内黑芥子酶或人体肠道菌群水解迅速转变为活性成分萝卜硫素。萝卜硫素虽然名字中有“萝卜”二字，但实际上它在萝卜中的含量极低，萝卜中的主要活性物质为萝卜素。含萝卜硫素的植物萝卜硫素是一种多功能酶诱导物，起到抗癌作用。
举例： But broccoli florets also pack a special compound called sulforaphane, which boasts some impressive potential benefits. It may even have anti-cancer effects, including on some types of skin cancer. Sulforaphane is likewise a powerful protective agent against sun damage. It works in two ways: neutralizing harmful free radicals and switching on other protective systems in your body.
但是西兰花也含有一种叫做萝卜硫素的特殊化合物，它有一些令人印象深刻的潜在好处。它甚至可能具有抗癌作用，包括对某些类型的皮肤癌。萝卜硫素同样是一种强大的防晒剂。它以两种方式起作用:中和有害的自由基和启动你体内的其他保护系统。
lycopene
英文解释：Lycopene /ˈlaɪ.koʊ.piːn/ is a type of organic pigment called a carotenoid. It is related to beta-carotene and gives some vegetables and fruits (e.g., tomatoes) a red color. Lycopene is a powerful antioxidant that might help protect cells from damage.
中文解释：指“番茄红素”。番茄红素是一种被称为类胡萝卜素的有机色素。它与β -胡萝卜素有关，并使一些蔬菜和水果(如西红柿)呈红色。番茄红素是一种强大的抗氧化剂，可能有助于保护细胞免受损害。
举例：Tomatoes are a great source of vitamin C and contain all of the major carotenoids, including lycopene. Beta carotene, lutein, and lycopene have been shown to protect your skin against damage from the sun. They may also help prevent wrinkling.
西红柿是维生素C的重要来源，含有所有主要的类胡萝卜素，包括番茄红素。β–胡萝卜素、叶黄素和番茄红素已被证明可以保护你的皮肤免受阳光的伤害。它们还可能有助于防止皱纹。
