10 Foods You and Your Grandkids Should Eat

You love your grandkids. They’re the cutest and smartest on the block. Chances are you take every opportunity to spend time with them. That probably means choosing meals and snacks together.

What’s the smartest choice?

“Growing kids typically have voracious appetites. They need lots of calories for fuel to grow and play,” says Kathleen Zelman, RD, director of nutrition for WebMD. “Grandparents don’t need as much as they get older. But beyond those differences, the guidelines for healthy food choices are the same.”

If you're the son or daughter of an aging parent, your kids' visits to grandma or grandpa can be a good opportunity for boosting the nutrition of both. Preparing many small portions of finger foods to have out and available can be helpful, especially if your parent has lost interest in cooking or eating, says Joanne Koenig Coste, a former caregiver and expert in family caregiving. She suggests dividing soybeans, baked vegetable chips, pine nuts, or pumpkin seeds into snack-size baggies to leave for healthy snacks. "Cut granola bars into four or six pieces for snacks," Coste says. "Make smoothies in advance that they can defrost and eat."

Grandparents who make smart food choices for their grandkids do more than keep them healthy, says Ruth Ann Carpenter, RD, author of Healthy Eating Every Day. “You’ll also serve as a role model, shaping their choices for the rest of their lives.”

For inspiration, turn to these top 10 foods that are perfect for people at almost any age.

1. Eggs

That’s right, eggs. Once vilified because they contain dietary cholesterol, eggs are back on the healthy menu. The cholesterol they contain is likely to have only a very minor effect on blood cholesterol, if any. “As long as you limit yourself to about one egg a day, you don’t need to worry,” says Zelman, who calls herself a “huge egg fan.” Eggs are packed with nutrients, protein, and unsaturated fats (as well as some saturated fat). They fill you up on relatively few calories. And they’re versatile. Zelman’s suggestions: egg and vegetable scrambles for

breakfast, hard-boiled eggs for a snack, and egg-salad sandwiches on whole-grain bread.

2. Milk and Other Dairy Products

The official federal dietary guidelines recommend three cups of low-fat dairy products a day for adults. Children 2 to 8 years should have 2 cups a day if they don't have a dairy allergy or lactose intolerance. The calcium in dairy products helps build strong bones in children and preserves bone strength in older people. Milk is an easy choice. For snacks, low-fat string cheese is nutritious and fun for younger kids. But when the grandkids are clamoring for a sweet treat, whip up a low-sugar-yogurt smoothie with fresh fruit.

2. Milk and Other Dairy Products continued...

Coste says that both younger and older people tend to have a sweet tooth, and family members can take advantage of this by making healthy, tasty desserts for them. She suggests making a pudding by substituting low-sugar yogurt for part of the water in strawberry Jell-O. Bring it over to Mom or Dad's with some ice cream cones. "Then the grandparent and grandchildren can eat the pudding out of ice cream cones," she says. "It's great fun and isn't that 'icy cold' if you have dental or denture issues."

Another healthy twist: Make a sandwich cookie by spreading cream cheese between two gingersnap cookies. "Nothing is going to make an older person lose the desire to eat like not getting to eat a treat once in a while," Coste says.

3. Whole-Grain Breakfast Cereal

Skip the sugary flakes and choose a breakfast cereal made with whole grains -- and only small amounts of added sugar. The first ingredient should be a whole grain. On a cold winter day, steel-cut hot oatmeal is a great choice. By adding a few raisins or fresh fruit, you can make cereal sweeter without piling on sugar. “Pour low-fat milk on top and you’ve got a well-balanced meal,” says Zelman.

4. Nuts

Nuts, like eggs, have been welcomed back into a healthy kitchen. Sure they are high in fat. “But the oil in nuts is mostly unsaturated, so it won’t raise heart disease risk,” says Penny Kris-Etherton, PhD, professor of nutrition at Pennsylvania State University. Studies show that people who snack on nuts have healthier hearts and are less likely to be overweight. If your grandkids aren’t keen on nuts, make up your own trail mix by adding raisins, dark chocolate chips, or pieces of dried coconut to a package of mixed nuts. Another great choice: peanut butter. “Kids love it, and you can smear it on toast for breakfast or a sandwich at lunch. Peanut butter on celery sticks also makes a great snack,” says Zelman.

5. Beans

Beans and lentils are nutritional powerhouses. They’re rich sources of fiber, protein, and many essential nutrients. Beans are also very satisfying, so you’ll feel full before you pile on too many calories. And they’re versatile. Baked beans are a great way to whet kids’ appetites for beans. Lots of kids also love chili and classic summer salads made with a mix of beans.

6. Tuna and Other Fish

Fish is a leading source of omega-3 fats, which are important at all ages. Research shows that omega-3 fats lower the risk of abnormal heart rhythms and levels of blood fats (triglycerides). Some research suggests a link to reduced risk of dementia, as well as help for joint problems and symptoms of ADHD.

7. Whole-Grain Bread

Who doesn’t love bread? Bread features in everything from French toast in the morning to sandwiches at lunch and bread pudding for dessert at night. The smartest choice, of course, is whole-grain bread, which packs more fiber and nutrients than refined-flour breads. Breads made with seeds or nuts pack even more nutrition. Studies show that people who eat more whole grains lower their risk of diabetes, heart disease, and other conditions, Zelman adds.

For people with blurred vision, Coste says, "White bread is eaten much less than wheat or pumpernickel. It's a visual thing, not a taste thing." So if you're an adult child who occasionally grocery shops for your parents, pick up a loaf of whole-grain bread and see if they prefer it.

For people with obesity, diabetes or prediabetes, keep bread portion sizes small. And there are lots of gluten-free choices for people who cannot tolerate gluten.

8. Pasta

Young kids love the variety of shapes and the taste of pasta. Choose whole-wheat pasta for more fiber and nutrition. Many very good basic tomato sauces are available on grocery store shelves these days, making it easy to put together a simple and delicious dish. Tomatoes are rich in antioxidants. For variety and added nutritional value, add chicken, beans, or vegetables such as chopped peppers or peas.

9. Colorful Vegetables

Health experts say kids and grandparents alike should try to eat vegetables every day.

?Children ages 2 to 3 need 1 cup of vegetables a day.

?Kids 4 to 8 need 1.5 cups.

?Older youth and adults 2 to 3 cups of vegetables a day, depending on gender and activity levels.

Very few Americans hit the mark. Vegetables can be a tough sell for young kids. To make them more palatable, choose brightly colored and

sweet-flavored vegetables, such as carrots, bell peppers, peas, and corn. Find fun ways to serve them: Decorate the top of a home-made pizza, for instance, or serve them with a cheese or hummus dip.

10. Fruit

Most Americans, young and old, also fall short of the recommended 1 to 2 cups of fruit a day. That’s too bad. Fruit is a great snack and a healthy alternative to sugary and fatty desserts. Fresh fruit is the top choice for nutrition. But frozen or canned fruit is a good alternative. Avoid products with added sugar or syrup.

不能吃的18种食物(怀孕期间)

1、螃蟹 它味道鲜美，但其性寒凉，有活血祛瘀之功，故对孕妇不利，尤其是蟹爪，有明显的堕胎作用。 2、甲鱼 虽然它具有滋阴益肾的功效，但是甲鱼性味咸寒，有着较强的通血络、散瘀块作用，因而有一定堕胎之弊，尤其是鳖甲的堕胎之力比鳖肉更强。 3、薏米 是一种药食同源之物，中医认为其质滑利。药理实验证明，薏仁对子宫平滑肌有兴奋作用，可促使子宫收缩，因而有诱发流产的可能。 4、马齿苋 它既是草药又可作菜食用，其药性寒凉而滑利。实验证明，马齿苋汁对于子宫有明显的兴奋作用，能使子宫收缩次数增多、强度增大，易造成流产。 对胎儿有害的食物 5、罐头食品 罐头食品在制作过程中都加入一定量的添加剂，如人工合成色素、香精、防腐剂等。尽管这些添加剂对健康成人影响不大，但孕妇食入过多则对健康不利。另外，罐头食品营养价值并不高，经高温处理后，食物中的维生素和其他营养成分都已受到一定程度的破坏。 6、菠菜 人们一直认为菠菜含丰富的铁质，具有补血功能，所以被当做孕期预防贫血的佳蔬。其实，菠菜中含铁不多，而是含有大量草酸。草酸可影响锌、钙的吸收。孕妇体内钙、锌的含量减少，影响胎儿的生长发育。 7、巧克力和山楂 过多食用巧克力会使孕妇产生饱腹感，因而影响食欲，其结果是身体发胖，而必需的营养却缺乏。孕妇较喜欢吃酸东西，山楂便成了首选果品。山楂对子宫有兴奋作用，孕妇过

食可使子宫收缩，导致流产的可能，故要少吃。 8、猪肝 芬兰和美国已向孕妇提出了应少吃猪肝的忠告。 因为在给牲畜迅速催肥的现代饲料中，添加了过多的催肥剂，其中维生素A含量很高，致使它在动物肝脏中大量蓄积。孕妇过食猪肝，大量的维生素A便会很容易进入体内，对胎儿发育危害很大，甚至会致畸。 9、久存的土豆注解１ 土豆中含有生物碱，存的越久的土豆生物碱含量越高。过多食用这种土豆，可影响胎儿正常发育，导致胎儿畸形。当然，人的个体差异很大，并非每个人食用后都会出现异常，但孕妇还是不吃为好，特别是不要吃长期贮存的土豆。 10、热性作料 孕妇吃热性作料 小茴香、八角、花椒、胡椒、桂皮、五香粉等容易消耗肠道水分， 使胃肠分泌减少，造成肠道干燥、便秘。发生便秘后，孕妇必然用力屏气解便，使腹压增加，压迫子宫内的胎儿，易造成胎动不安、早产等不良后果。 11、味精 味精的主要成分是谷氨酸钠，血液中的锌与其结合后便从尿中排出，味精摄入过多会消耗大量的锌，导致孕妇体内缺锌。而锌是胎儿生长发育之必需品，故孕妇要少吃。 12、桂圆、荔枝 性温热易致胎热； 13、石榴 贫血者要少吃. 14、腌制酸菜 含有亚硝胺，可导致胎儿畸变。 15、西瓜 每天吃水果不宜超过250g，限量吃西瓜，因为西瓜是利尿剂，容易造成孕妇脱水。

孕妇绝不能吃这四类食物

这四类食物损害胎儿智商孕妇绝不能吃生个聪明宝宝孕妇不能吃什么？ 生一个聪明伶俐的宝宝，称得上是每个准妈妈的期望，除了在孕期注重胎教以外，在饮食上孕妈妈们也要格外注意，有些食物会损害胎儿大脑发育，堪称胎宝宝的聪明杀手，孕妈妈们要远离它。 孕妇不能吃的食物：味精 味精的主要成分是谷氨酸钠，血液中的锌与其结合后便从尿中排出，味精摄入过多会消耗大量的锌，医学研究表明，妊娠后期的孕妇多吃味精，会引起胎儿缺锌，而锌是胎儿生长发育之必需品，它影响孩子出生后的体格和精神发育，因此为了宝宝智力，孕妈妈们要少吃味精。 世界卫生组织曾提出：成人每天摄入味精量不得超过4克，孕妇和周岁以内的孩子禁食味精。动物试验佐证了，周岁以内的孩子食用味精过多有引起脑细胞坏死的可能，因此妈妈们也要注意了，即使孩子大了也尽量少给它吃含味精多的食物。 食物不够鲜美时，加点味精能提鲜，那么孕妈妈不宜吃的味精有什么可替代的呢?烧肉时放一点点糖，同样可以达到提鲜的效果。平时不妨自己熬点高汤用吧，效果其实比味精更好呢。下面就来自己动手做健康易储存的放心高汤吧。 宝宝的聪明杀手二：榨菜 榨菜属于过咸食物，其中含有较多的盐分，其实人体对食盐的生理需要极低，成人每天7克以下，儿童每天4克以下即可。习惯吃过咸食物的人，不仅会引起高血压、动脉硬化等疾病，还会损伤动脉血管，影响脑组织的血液供应，使脑细胞长期缺血缺氧，导致智力迟钝，记忆力下降，榨菜类的腌制酸菜中还含有亚硝胺，可能导致胎儿畸变，所以孕妈咪不宜多吃此类食物，甚至与榨菜相似的咸菜、咸肉、豆瓣酱等也应少吃。 像这类过咸的榨菜放置过久，并不是好的营养食物，孕妈妈多吃新鲜的应季蔬菜才是健康之道。胡萝卜含有大量以维生素A为主的多种维生素、无机盐和钙质等，营养丰富，有“小人参”的美誉，为健脑佳品，孕妈妈厌倦了胡萝卜入菜，不妨试着做一道胡萝卜苹果汁吧。

This is likely due largely to the physical changes of our nerves and neurons (神经元). New research suggests 'rapid fire' abilities of the young brain allow us to process more information during youth, causing the days to seem longer earlier in life. However, as we get old, researchers say the older brain takes more time to process information. The new finding put forward by a Duke University researcher was published in a paper in the journal European Review this week According to Adrian Bejan, the J. A Jones Professor of Mechanical Engineering at Duke, the physical changes of our nerves and neurons play, a major role in our perception (知觉) of time as we get old. Over the years these structures become more complex and eventually begin to degrade. "Little babies, for example, move their eyes much more often than adults because they're processing images at a faster rate," Beian says, For older people, this means fewer images are being processed in the same amount of time, causing experiences to seem as though they're happening more quickly. （1）What causes time to fly faster as we get old? A. Changes of our nerves and neurons. B. Information in our brain. C. The electrical signals. D. Rapid fire abilities. （2）What is unavoidable in the process of getting old? A. Longer days. B. Aging brains. C. More images. D. Less experience.（3）Why do the days seem longer earlier in life? A. Young people are more energetic in their life. B. The younger brain takes less time to process information. C. Old people have fewer things to do than young people. D. Little babies move their eyes much more often. （4）What is the best title of the text? A. Nerves and Neurons B. Time Flies Fast C. The Older, the Faster D.

A The Gunpowder Plot was a conspiracy(阴谋) to kill King James Ⅰ，as well as the members of the House of Lords and Commons at the re-opening of Parliament.It was designed by a group of Catholics in protest against the anti-Catholic laws that were being introduced by the king. Robert Catesby was the leader of the group.It was he and his cousin，Thomas Wintour，and two other friends，Thomas Percy and John Wright，who formed the center of the group.They were joined by nine more men；among them was Guy Fawkes，from the city of York in the north of England. Fawkes found a store room directly under the House of Lords and rented it out under the false name of John Johnson.The conspirators stored thirty-six barrels of gunpowder there，and Fawkes，who was an explosives expert，was to light the fuses(引信) on 5th November 1605. The plot failed because one of the conspirators，Francis Tresham，sent a letter to his relative，who was a member of the House of Lords.The letter warned him not to attend the opening ceremony of Parliament.The letter was passed on to the authorities，who took action. Guy Fawkes was found in the cellar on the night of 4th November with the thirty-six barrels and a number of fuses.He was imprisoned and ill-treated，eventually giving away the names of the conspirators. Soldiers of the king surrounded Holbeach House，in the Midlands，where they knew the conspirators to be hiding.In the fight that followed，four of them were shot dead，including Catesby and Percy，who were actually killed by the same bullet.The others were imprisoned and hanged along with Guy Fawkes on 31st January 1606. These days，on 5th November，children all over Britain celebrate Guy Fawkes Night by building huge bonfires and lighting fireworks.It’s a family tradition and an occasion to eat potatoes baked by the flames.There is always a “guy”on top of the fire，a model of Guy Fawkes，dressed in the clothes of the 17th century. 1．Francis Tresham wrote the letter to his relative to . A．warn him of the danger of being killed B．reveal the names of the conspirators C．protect the House of Lords

2019届高考英语阅读理解：科普类说明文----有解析

科教科普类 1、Australia leads the world in its number of resident poisonous spiders as well as the strength of their toxicity(毒性). However,of almost 9,800 species most are perfectly harmless and interesting. Spider diversity is broad and many fascinating species occur here that range from the large to the tiny and hardly noticed, and from the dullest black to the strangely shaped. Spiders can be roughly classified according to the strategies(策略) they use for feeding. Spiders which appeared earlier in the evolutionary scale feed by waiting in a cave for food to come along before grabbing it. Following them were spiders which actively wandered looking for food and which caught it by chasing it down. The evolution of flying insects makes spiders evolve ne w ways of catching food which couldn’t be chased and so the earliest air web weavers arose. Most spiders feed on insects and other arthropods but the Whistling Spider feeds on frogs and small birds. The Golden Orb Spider also feeds on small birds. A spider periodically sheds(蜕皮;脱落) its skin so that it can grow. Immature stages are called moults. Each species has a particular number of moults that it will go through before reaching its final adult stage. Usually, once male spiders have mated, they die shortly after. But, even in death, Redback males often serve a purpose. The already pregnant Redback females always kill their lover and, in most cases, also eat them. This provides them with a small reproductive advantage. Allowing spiders to take up places around houses can be beneficial in that they catch other annoying insects such as mosquitoes and flies. Rest assured that while you might see some large spiders, and perhaps even some poisonous ones, a good rule is to look and admire but don't touch any spider you find. Even those without poison could still have a nasty bite. 1.Different families of spiders are identified themselves by ______. A.their physical character B.their ways of getting food C.the strength of their toxicity D.their effect on the environment 2.What are the latest spiders in their evolution process?

怀孕女人18种食物绝对不能碰。

建议：怀孕女人18种食物绝对不能碰。 一、容易流产食物： 1、螃蟹 它味道鲜美，但其性寒凉，有活血祛瘀之功，故对孕妇不利，尤其是蟹爪，有明显的堕胎作用。 2、甲鱼 虽然它具有滋阴益肾的功效，但是甲鱼性味咸寒，有着较强的通血络、散瘀块作用，因而有一定堕胎之弊，尤其是鳖甲的堕胎之力比鳖肉更强。 3、薏米 是一种药食同源之物，中医认为其质滑利。药理实验证明，薏仁对子宫平滑肌有兴奋作用，可促使子宫收缩，因而有诱发流产的可能 4、马齿苋 它既是草药又可作菜食用，其药性寒凉而滑利。实验证明，马齿苋汁对于子宫有明显的兴奋作用，能使子宫收缩次数增多、强度增大，易造成流产。 二、对胎儿有害的食物 5、罐头食品 罐头食品在制作过程中都加入一定量的添加剂，如人工合成色素、香精、防腐剂等。尽管这些添加剂对健康成人影响不大，但孕妇食入过多则对健康不利。另外，罐头食品营养价值并不高，经高温处理后，食物中的维生素和其他营养成分都已受到一定程度的破坏。 6、菠菜 人们一直认为菠菜含丰富的铁质，具有补血功能，所以被当做孕期预防贫血的佳蔬。其实，菠菜中含铁不多，而是含有大量草酸。草酸可影响锌、钙的吸收。孕妇体内钙、锌的含量减少，影响胎儿的生长发育。 7、巧克力 过多食用巧克力会使孕妇产生饱腹感，因而影响食欲，其结果是身体发胖，而必需的营养却缺乏。孕妇较喜欢吃酸东西，山楂便成了首选果品。山楂对子宫有兴奋作用，孕妇过食可使子宫收缩，导致流产的可能，故要少吃。 8、猪肝 芬兰和美国已向孕妇提出了应少吃猪肝的忠告。 因为在给牲畜迅速催肥的现代饲料中，添加了过多的催肥剂，其中维生素A含量很高，致使它在动物肝脏中大量蓄积。孕妇过食猪肝，大量的维生素A便会很容易进入体内，对胎儿发育危害很大，甚至会致畸。 9、久存的土豆 土豆中含有生物碱，存的越久的土豆生物碱含量越高。过多食用这种土豆，可影响胎儿正常发育，导致胎儿畸形。当然，人的个体差异很大，并非每个人食用后都会出现异常，但孕妇还是不吃为好，特别是不要吃长期贮存的土豆。 10、热性作料 孕妇吃热性作料熜≤钕恪八角、花椒、胡椒、桂皮、五香粉等容易消耗肠道水分，使胃肠分泌减少，造成肠道干燥、便秘。发生便秘后，孕妇必然用力屏气解便，使腹压增加，压迫子宫内的胎儿，易造成胎动不安、早产等不良后果。 11、味精 味精的主要成分是谷氨酸钠，血液中的锌与其结合后便从尿中排出，味精摄入过多会消耗大量的锌，导致孕妇体内缺锌。而锌是胎儿生长发育之必需品，故孕妇要少吃。

(英语)高考英语阅读理解(科普环保)专项训练及答案及解析

（英语）高考英语阅读理解(科普环保)专项训练及答案及解析 一、高中英语阅读理解科普环保类 1．犇犇阅读短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。 A shark moving around the coastline is normally a worrying sight，but this waterborne drone (无人机) threatens floating rubbish instead of people. Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration with its whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast. According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet (1.5 meters by 1.1 meter), it can carry up to 352 pounds of rubbish (159.6 kg) and has an operational battery life of 16 hours. By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat. "WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines," said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches." "Our drones are designed to move through a water system, whether it's around the perimeter (周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remote-controlled model and just under $ 23, 000 for the autonomous model." Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination of new technology, preventative measures and changing people's attitudes towards littering. （1）What do we know about the WasteShark? A. It can frighten sharks away. B. It is an ocean explorer. C. It is a rubbish collector. D. It can catch fish instead of people. （2）What does Paragraph 4 mainly tell us? A.

哪些食物孕妇千万不能吃 从知道已怀有身孕开始，妈妈、奶奶、姨妈、姑姑便纷纷提供心得，说这些不能吃，那些切忌食。其实这些孕妇传统禁忌有多少是对，多少是错的呢？还有，有哪些食物，是孕妇真正要敬而远之的呢？这里让我们详细道来。 传统谬误： 1.不要吃生冷、寒冷的食物，如凉粉、西瓜、雪糕，这会造成早产，甚至小产呢！ 这是无科学根据的，但孕妇吃后不舒服如出现泻肚子，就最好暂停食用，不过，对胎儿是绝对无影响的。2.吃羊肉会令胎儿“发羊吊”？ 羊痫风(癫痫的通称)和羊肉是没有关系的，而且羊肉含丰富维他命B12和铁质，营养丰富，孕妇吃绝对有益无害。 3.多喝鲜奶，生出来的婴儿皮肤会很白？ >>>孕期食物七宗“最” 胎儿的皮肤颜色是受父母的遗传基因影响，于成孕那一刻便已决定，与怀孕期的饮食无关。 4.吃虾蟹会令胎儿的皮肤差和产生皮肤敏感？ 如果孕妇本身对虾蟹有敏感，在怀孕期应避免进食，这是恐怕孕妇对虾蟹敏感的情况遗传给胎儿的机会增加。而没有敏感的孕妇，就算吃了都不会令胎儿的皮肤差和产生皮肤敏感。 有医学根据的饮食禁忌 1.不要过量吸取维他命A。 孕妇摄取太多的维他命A，会导致早产和胎儿发育不健全，所以每日只可摄取400-1250微克的维他命A，其中猪肝含极丰富维他命A，孕妇切忌过量进食。 2.要限制饮用含咖啡因的饮品。 摄取太多咖啡因会影响胎儿的骨骼成长，有可能出现手指、脚趾畸形的情况，也会增加流产、早产、婴儿体重过轻的情况。最好避免饮用含有咖啡因的饮品，如果非喝不可，每日不可多过2杯咖啡或3杯半浓茶。 3.避免喝酒 如果喝太多酒，会令胎儿畸形，影响胎儿智商和生理上的发展，基本上是避免喝。2杯啤酒、或1杯葡萄酒为极限。 >>>孕期危害胎儿的18种食物 4.避免高糖、高脂肪食物 吃太多高糖、高脂肪食物如汽水、糖、薯片，令孕妇过胖，从而增加妊娠性糖尿病、妊娠性高血压的情况，除增加日后患糖尿病和血压高的机会之外，分娩时也会有困难。 孕妇是一生中的特殊阶段，生一个健康聪明的小宝宝，又是每个孕妇的最大心愿。科学地选择食物不仅有利于母体健康，更有益于胎儿的发育。 最佳防吐食物 晨吐是孕妇最难受也是最常见的反应之一，给孕妇带来相当大的痛苦。选择适合孕妇口味的食物有良好的防吐作用，营养学家认为，柠檬和土豆含有多种维生素，对孕妇尤为合适。 最佳保胎蔬菜 菠菜含有丰富的叶酸，每100克菠菜的叶酸含量高达350微克，名列蔬菜之首。 叶酸的最大功能在于保护胎儿免受脊髓分裂、脑积水、无脑等神经系统畸形之害。因此专家主张早期的两个月内应多吃菠菜或服用叶酸片。同时，菠菜中的大量B族维生素还可防止孕妇盆腔感染、精神抑郁、失眠等常见的孕期并发症。 最佳饮料 绿茶乃微量元素的“富矿”，对胎儿发育作用突出的锌元素就是其中一种。根据测定，在食谱相同的情况下，常饮绿茶的孕妇比不饮者每天多摄取锌达14毫克，此外，绿茶含铁元素也较丰富，故常饮绿茶可防贫血。

He really wanted to have them for his birthday. He sadly walked away and thought how to tell his mother about it. He knew she would give him anything he liked if she could. But he also knew very well she had little money. He decided not to go home at once, as he looked worried and his mother would notice (注意)it. So he went to the park and sat on the grass.
