牛奶,被誉为是ə“营养最接近完善的食品”。

它是人体钙质的最佳来源,而且钙磷比例非常适当,利于钙的吸收。



《中国居民膳食指南》建议每个成年人每天应该要摄入300克奶或奶制品,保证每天的钙需求。



牛奶这么好,但您会喝吗?


很多人可能要说,这有什么难的!殊不知,有时一些搭配不当,可能会造成严重的中毒反应!


此外,对于牛奶,大家存在很多误区,比如迷信高钙奶更加补钙、以为价格更高的奶营养更高等等,今天,我们分别来看看。


错误一:以为晚上喝牛奶可催眠


说到喝牛奶的最佳时间,有些人可能要说:肯定是晚上,因为晚上喝奶有助睡眠;有些人要说:早上喝奶好,更利于营养吸收。


其实,这两种说法都是没有依据的。牛奶中的确有助镇静的成分,但含量不高,它对睡眠的影响微乎其微。©早晨喝奶还是晚上喝奶,营养差别不大。 


但要是想为喝奶找个最佳时机,那么是——饭前30分钟最佳!

有研究发现,吃同样的一餐,如果在餐前30分钟喝牛奶,然后再吃饭,能有效降低餐后血糖。如果在吃饭的同时喝牛奶,虽然也有效,但不如餐前30分钟效果明显。

`

所以,如果餐前喝奶的时间合适,比餐后喝能更有效地控制餐后血糖上升。


而餐后血糖上升延缓,意味着餐后饱腹感能持续更长时间,餐后合成脂肪的风险也会明显下降,这对于预防肥肉上身是非常有好处的。

Ⅷ饭前半小时是最佳的喝奶时间,既控血糖又能预防长胖,真是一举两得的好事情!


错误二:认为牛奶越贵,营养价值越高


我们常看到,超市里售卖的牛奶常有两种:一是利乐包装的牛奶,保质期通常有30天;另一种是在冷柜里,保质期只有7天甚至更短的巴氏杀菌牛奶。


而保质期更短的巴氏杀菌奶,价格有时是前者的2倍。


♕那么,巴氏杀菌奶更优于利乐包装的常温奶吗?


四川省人民医院临床营养科周雪营养师表示,巴氏杀菌牛奶采用的是低温消毒的方法,只杀死致病菌,保留有益菌种,比如乳酸菌。


㉡因为保留了一部分有益人体的好细菌,因此对存储要求较高,更容易变质。


经过巴氏杀菌的牛奶,其中的钙质、维生素C、乳清蛋白保留得也更多;


²而利乐包装的常温奶通过高温瞬时杀菌的方法,把牛奶当中的一切微生物全部杀灭,因此保存更方便,但营养保留不如前者。


喝牛奶的坏处

所以,有条件的朋友,推荐每天选择巴氏杀菌的牛奶。如果不方便喝巴氏杀菌的牛奶,选择常温奶也可以满足对牛奶的营养需求


︵:♜

错误三:以为高钙奶更补钙


钙奶当中的钙质,确实比普通牛奶中含量多。但是,牛奶中的钙越多就越好吗?

н

喝牛奶的坏处补钙要考虑吸收效果,并非吃多少就能补多少。


牛奶这种食物本身就含有足够的钙质,只要喝足量(300ml),配合饮食摄入的其他钙质,就满足了身体对钙的需求,没必要去买高钙奶来补钙。


ㄉ此外,添加太多的钙,则容易造成蛋白质体系的不稳定,使得蛋白质沉淀,影响口感和品质。


没必要买高钙奶,纯牛奶就能很好地满足补钙需求。


ʃ错误四:乳糖不耐受,还空腹喝


乳糖不耐受人群体内缺乏分解乳糖的乳糖酶,因此在喝奶后会出现肚子胀、甚至腹泻症状。


Φ

那么,乳糖不耐受的人该如何喝牛奶?


Ú营养师建议——


σ﹏

乳糖不耐受人群在喝牛奶前肚子里“垫”点东西,不要空腹喝牛奶,搭配着食物来喝少量的牛奶也是可以的,或者也可以喝舒化奶、酸奶。


错误五:把牛奶盒也放进微波炉加热


牛奶隔袋加热,并不会让包装中的有害成分溶解到牛奶里,但是,这种软质材料的包装,是为了便于购买和携带,并不是用来作为加热容器



想要喝袋热牛奶,可以用100℃以下的热水烫一下袋装奶,让牛奶变得温热。


如果需要用微波炉加热牛奶,必须倒入微波炉专用容器,加热1分钟左右就行了。


错误六:吃药前后喝牛奶!


吃药前后,别吃喝牛奶。这一点慢性疾病患者,中老年人需要特别注意。轻则影响药效释放,严重的,还能增加药物毒性。

因为牛奶与药物同服时,可在药物表面和胃黏膜形成一层薄膜,待薄膜被消化吸收后,药物已错过了最佳吸收期,因此降低了药物的吸收和疗效。


这些药不能与喝牛奶一起服用:


地高辛,牛奶中钙可能增加地高辛的毒性;

止泻药,被牛奶“包裹”而失效;


四环素类抗生素,与牛奶中钙在肠道螯合,减少药物吸收;


含铁的药物,牛奶中的钙和铁在十二指肠竞争吸收,减少药物吸收;


左旋多巴,牛奶在肠道分解产生大量氨基酸,阻止左旋多巴在肠道吸收;


⒏‹雌激素,牛奶使代谢酶活性增加,减弱此类药物疗效。


服药与喝牛奶需至少间隔一小时。


关于牛奶的科普,今天就说到这,有没有刷新你的知识?


冬天快到了,既然说到了牛奶,那就再教大家一个做奶茶的小方法吧:

自煮奶茶


【原料】

牛奶 800ml;水 1200ml;冰糖:90克;红茶叶10克。


【做法】

水烧开后加入茶叶和冰糖同煮,待茶汤⺮颜色变深倒入牛奶,小火继续煮几分钟,煮到出现小气泡,然后关火,晾凉。


﹢最后把其中的茶叶用滤网过滤出来,再装入容器,就可以喝了~味道不比外边卖的茶,而且更安全营养。



Dont eat it when you drink milk, it is harmful to your body! Drinking milk like this every day, its better not to drink... Millions of people subscribed to the WeChat account. Click on the blue word Chinese Medicine Health Care under the title for free attention, we will provide you with positive, healthy, empowering, hopeful people and things, and valuable extended reading. Milk is known as the food with the closest nutrition to perfection. (Image source: Vision China) It is the best source of calcium in the human body, and the ratio of calcium to phosphorus is very appropriate, which is conducive to calcium absorption. The Dietary Guidelines for Chinese Residents recommends that every adult should consume 300 grams of milk or dairy products every day to ensure daily calcium requirements. Milk is so good, but can you drink it Many people may want to say, what is so difficult about this! As everyone knows, sometimes some mismatches may cause serious poisoning reactions! In addition, there are many misunderstandings about milk, such as the superstition that high-calcium milk is more calcium supplement, and that higher-priced milk is more nutritious. Today, lets take a look separately. Mistake 1: Thinking that drinking milk at night can be hypnotized. When it comes to the best time to drink milk, some people may say: It must be at night, because drinking milk at night helps sleep; some people say: Drinking milk in the morning is better for nutrient absorption . In fact, these two claims are unfounded. Milk does have calming ingredients, but the content is not high, and its effect on sleep is minimal. There is little nutritional difference between drinking milk in the morning or at night. u0026nbsp;But if you want to find the best time to drink milk, then it is-30 minutes before meals are the best! Studies have found that eating the same meal, if you drink milk 30 minutes before the meal, and then eat, can effectively reduce the blood sugar after the meal. If you drink milk while eating, although it is also effective, it is not as effective as 30 minutes before the meal. Therefore, if the time of drinking milk before a meal is appropriate, it can be more effective to control the increase in blood sugar after a meal than drinking it after a meal. The delayed rise of blood sugar after a meal means that the feeling of fullness after a meal can last longer, and the risk of synthesizing fat after a meal will also be significantly reduced, which is very good for preventing fat upper body. Half an hour before a meal is the best time to drink milk. It can control blood sugar and prevent weight gain. It is a good thing to kill two birds with one stone! Mistake 2: The more expensive milk is, the higher the nutritional value. We often see that there are two types of milk sold in supermarkets: one is Tetra Pak packaged milk, with a shelf life of 30 days; the other is in a freezer, with shelf life Pasteurized milk with only 7 days or less. The price of pasteurized milk with a shorter shelf life is sometimes twice that of the former. So, is pasteurized milk better than Tetra Paks room temperature milk Nutritionist Zhou Xue from the Clinical Nutrition Department of Sichuan Provincial Peoples Hospital said that pasteurized milk uses a low-temperature disinfection method to kill only pathogenic bacteria and retain beneficial bacteria, such as lactic acid bacteria. Because it retains a part of the good bacteria that are beneficial to the human body, it has higher storage requirements and is more prone to deterioration. Pasteurized milk contains more calcium, vitamin C, and whey protein. The room temperature milk packaged by Tetra Pak kills all microorganisms in the milk through high temperature instantaneous sterilization, so it is preserved More convenient, but the nutrient retention is not as good as the former. The disadvantages of drinking milk Therefore, friends with the conditions recommend choosing pasteurized milk every day. If it is not convenient to drink pasteurized milk, choosing room temperature milk can also meet the nutritional needs of milk. Mistake 3: Think that high-calcium milk is more calcium-supplementary. The calcium content in calcium milk is indeed more than that in ordinary milk. But, the more calcium in milk, the better The disadvantages of drinking milk for calcium supplementation depends on the absorption effect, rather than supplementing as much as you eat. Milk is a food that contains enough calcium. As long as you drink enough (300ml) and other calcium intake in your diet, your bodys demand for calcium will be met. There is no need to buy high-calcium milk to supplement calcium. In addition, adding too much calcium will easily cause the instability of the protein system, cause protein precipitation, and affect the taste and quality. There is no need to buy high-calcium milk, pure milk can well meet the calcium demand. Mistake 4: Lactose intolerance, and people who drink lactose on an empty stomach lack the lactase enzyme that breaks down lactose. Therefore, they will have stomach bloating and even diarrhea after drinking milk. So, how should people with lactose intolerance drink milk Nutritionists suggest that people with lactose intolerance should pad something in their stomachs before drinking milk. Do not drink milk on an empty stomach. It is also okay to drink a small amount of milk with food, or you can drink Shuhua milk and yogurt. Mistake 5: Putting the milk carton in the microwave oven to heat the milk compartment will not dissolve the harmful ingredients in the milk. However, the packaging of this soft material is for easy purchase and carrying, not for use. Comes as a heating vessel. If you want to drink a bag of hot milk, you can scald the bag of milk with hot water below 100℃ to make the milk warm. If you need to heat the milk in a microwave oven, you must pour it into a special microwave oven and heat it for about 1 minute. Mistake 6: Drink milk before and after taking medicine! Do not eat or drink milk before and after taking the medicine. Patients with chronic diseases, middle-aged and elderly people need special attention. It can affect the release of the drug effect at a slight level, and increase the toxicity of the drug in severe cases. Because milk and medicine are taken together, a film can be formed on the surface of the medicine and the gastric mucosa. After the film is digested and absorbed, the medicine has missed the optimal absorption period, thus reducing the absorption and efficacy of the medicine. These drugs cannot be taken with milk: digoxin, the calcium in milk may increase the toxicity of digoxin; antidiarrheal drugs, which are wrapped by milk and become ineffective; tetracycline antibiotics, chelate with the calcium in milk in the intestines and reduce Drug absorption; iron-containing drugs, calcium and iron in milk compete for absorption in the duodenum, reducing drug absorption; levodopa, milk is broken down in the intestine to produce a large amount of amino acids, preventing levodopa from being absorbed in the intestine; estrogen , Milk increases the activity of metabolic enzymes and weakens the efficacy of such drugs. There must be at least one hour between taking medicine and drinking milk. As for the popular science of milk, thats it today. Have you refreshed your knowledge Winter is coming soon. Now that we talked about milk, let me teach you a little way to make milk tea: self-cooked milk tea [raw material] milk 800ml; water 1200ml; rock sugar: 90g; black tea leaves 10g. [Method] After the water is boiled, add the tea leaves and rock sugar and cook together. When the tea soup becomes darker, pour the milk into it. Continue to boil for a few minutes on low heat until small bubbles appear, then turn off the heat and let cool. Finally, filter the tea leaves with a strainer, and then put them into a container, and you can drink it~ It tastes no better than the tea sold outside, and is safer and more nutritious.
