Science drink milk little common sense 5
Drinking milk is good for health, but many people drink milk in still exist a number of the error on the idea, this paper introduces some scientific drinking milk little common sense.
The 1 morning fasting drink milk should not be. Because the human body when fasting gastrointestinal peristalsis quickly, nutrition in milk are often too late to be absorbed quickly into the e.. In addition, big milk method is insufficient, because this will reduce in oral and salivary mixed opportunity, is not conducive to digestion and absorption. Drink milk before the best to eat some cookies, cakes, or eat snacks while drinking milk.
2 night milk more favorable. Scientific studies found that, in the human body calcium metabolism will have a special rule: the evening especially midnight when the content of serum calcium, there will be a" trough", forcing the body through regulating mechanism of transport a portion of bone calcium supplement. In this way, calcium in the blood is temporarily maintained, but have reduced skeletal calcium in. Milk of calcium rich, therefore before bedtime drink a cup of milk, can compensate for human body needs calcium at night.
3 milk should not be adding sugar boiling. Milk is rich in amino acids, in the condition of high temperature in the milk of lysine with sugars occurring Maillard reaction, generate a new compounds - fructosyl amino acid. This substance can not only for human digestion and absorption, but affect human health, the best milk fresh drinking, such as cold a little heating can.
4 do not like milk can drink yoghurt. The milk has a" repulsive " most people with lactose intolerance, these people can try drinking yoghurt. In the yogurt lactose content significantly reduced, but almost all retain the milk nutrition, wherein the lactic acid bacteria in the human body can survive and reproduction, conducive to nutrient absorption and utilization and improve immunity. Yogurt not containing antibiotics, easy to digest the absorption to fasting drinking.
5 can not be heated drinking yoghurt. Drink sour milk feeds mainly on its nutrition and live bacteria, such as yogurt heating, the body can only drink nutrition to lose biological activity of lactic acid bacteria, so don't heating after drinking.
How birds sleep
During the day, the birds in the branches through singing, fly freely in the blue sky, in the evening, they and we like to rest, sleep, restores the physical strength, but their sleeping position but each are not identical!
Beautiful mallard ducks and swans, under water in daytime, and the rest of the night when the predator, also cannot leave their most loves water. They have beautiful long neck bending forward, head buried in the wings, and then let themselves floating in the water, while dreaming, and swim, is leisurely.
Crane, stork, heron, long-legged bird always stand on one leg and sleep, tired to change the other foot rest, is a model.
Partridge rest like swarms around in a circle, and then as head outwards inward end. In this way, regardless of the enemy from which direction the hit, they can find and run away.
Thrush, Braun and other sounds melodious birds, sleep usually bent legs, claws bent up firmly grasp branches, so don't worry they will fell down from the tree.
While the" night owl" birds of prey in the daytime, you can always see it open one eye, one eye closed, standing in the thick branches, in fact it is sleeping. The sleeping posture is it right? Very offbeat ah, it is in order to monitor the surrounding environment against enemy attack!

The fish will drown me
Fish have gills, can breathe water, fishes have a swim bladder, can be in the water freely ups and downs. However, some people say the fish that lives in the water will drown, is this true?
Although it sounds ridiculous, but it is true. Fish is fish swimming" buoy", which can be inflated and deflated to adjust the proportion of fish body. In this way, the fish in the swimming requires only minimal muscle activity, will be in the light of floating stability. However, when the fish sink to a certain depth ( i.e." depth" ), the outside huge pressure will cause it to wither section bladder volume. At this time, it 's buoyancy less than its own gravity, so he can't help to submerged to, also do not float, and was ultimately unable to breathe and drowned. Although, the fish also can swing through fins and tail upwards, but if the sink too deep, do also be of no avail.
On the other hand, living in the deep sea fish, because their bones can bear great pressure, so they can live a free life in deep water. If we live in the deep sea fish fast to get the" depth" of above, because it is the inner pressure of the body not with the outside world smaller pressure equilibrium is reached, it will constantly" expansion" to float to the surface. Sometimes, it even took out," burst".

A dull boy
Greedy will decrease cerebral blood flow
If an excessive eating or stop a moment to eat, the body volume of blood, including brain blood mobilization to the gastrointestinal tract. While adequate blood supply is the development premise, if often in ischemic state, its development must be affected.
Greedy will cause obesity brain""
Over-eating, especially the intake of nourishing food, food into energy will greatly exceed the consumption quantity of heat, the heat energy into fat accumulation in the body. If the brain too much fat, obesity can cause brain"". Research confirms, human intelligence and cerebral sulci folds much about, cerebral sulcus and more obvious, more folds, the higher the level of intelligence. While obesity brain make groove back tightly abutted together, folds disappeared, the cerebral cortex was smooth, and the neural network development difference, so, intellectual level can be reduced.
Greedy will inhibit brain intelligent regional physiological function
The human brain activity patterns of excitation and inhibition is mutually induced in certain parts of the brain, is excited, its adjacent to the site of some areas in the inhibited state, excited more strengthen, peripheral site inhibition is more deepen, and vice versa. Therefore, if the head of the gastrointestinal tract to digest plant nerve center for gluttonous excess food and long time excited, it is bound to cause adjacent language, thinking, memory, imagination and intelligence of brain regional inhibition. These areas such as often is in the state of suppression, intelligence will be worse.
Greedy for constipation and brain damage
Children's snack mostly with high nutrition fine food, eat easy constipation. Constipation, metabolite accumulation in the digestive tract for a long time, the role of intestinal bacteria produce a large quantity of harmful substances, easily treated by intestinal absorption, into the blood circulation, stimulate the brain, the brain nerve cells of chronic poisoning, affecting the normal development of the brain.
Greedy will induce brain failure
Scientists found in a study, one can induce brain senescence substances -- fibroblast growth factor, due to increased satiety of food after tens of thousands of times, this is a kind of arteriosclerosis substance, so from long-term sense, greedy will cause premature aging of the brain.
科学饮乳小常识5则
喝牛奶有益健康，但不少人在喝奶方面还存在一些观念上的误区，现介绍一些科学饮乳的小常识。
1.晨起空腹喝奶不宜。因为人体空腹时胃肠蠕动快，牛奶中营养物质往往来不及被吸收就匆匆进入大肠。此外，大口喝奶的方法也不足取，因为这样会减少在口腔中和唾液混合的机会，不利于消化吸收。喝牛奶前最好先吃些饼干、糕点等，或边吃点心边喝牛奶。
2.晚上喝奶更有利。科学研究发现，人体中的钙代谢会有一个特殊的规律：晚间尤其是午夜之际，血浆钙含量会出现一个"低谷"，迫使机体通过调节机制调运一部分骨骼中的钙来补充。这样，血液中的钙虽暂时得到维持，但骨骼中钙却有减少。牛奶中含钙丰富，因此临睡前喝杯牛奶，可补偿人体夜间对钙的需求。
3.牛奶不宜加糖煮沸。牛奶中含有丰富的氨基酸，在高温条件下牛奶中的赖氨酸与糖发生梅拉德反应，生成一种新化合物--果糖基氨基酸。这种物质非但不能为人体消化吸收，反而影响人体健康，牛奶最好新鲜饮用，如太冷稍稍加热即可。
4.不喜牛奶可饮酸奶。对牛奶有"反感"的人大多患乳糖不耐症，这些人可尝试饮用酸奶。酸奶中的乳糖含量大大降低，但几乎保留了牛奶所有的营养，其中的乳酸菌在人体内能存活繁殖，有利于营养物质的吸收利用并提高免疫力。酸奶中不含抗菌素，易消化吸收所以能空腹饮用。
5.酸奶不能加热饮用。喝酸奶主要吃它的营养和活菌，如酸奶加热，人体只能喝到营养却失去了有生物活性的乳酸菌，因此不要加热后饮用。
鸟怎样睡觉的
白天，鸟儿们在枝头穿梭呜叫，在蓝天下自由飞翔，到了晚上，它们和我们人一样也要休息、睡觉，恢复体力，不过它们睡觉的姿势可是各不相同哦!
美丽的绿头鸭和天鹅们，白天在水中捕食、戏耍，夜晚休息时也离不开它们最爱的水面。它们把优美的长脖子弯曲着，将头埋在翅膀里，然后让自己漂浮在水面上，一边做着美梦，一边随波逐流，好不悠闲。
鹤、鹳、鹭等长腿鸟总是单脚独立而睡，累了再换另一只脚，是劳逸结合的典范。
鹧鸪休息时喜欢成群围成一个大圈，然后一律头朝外尾向内。这样，不管敌人从哪个方向袭来，它们都能及时发现并逃走。
画眉、百灵等叫声悦耳的小鸟，睡觉时通常弯下两腿，爪子则弯曲起来牢牢地抓住枝条，所以不用担心它们会从树上摔下来。
而猫头鹰这种“值夜班”的猛禽，你总能在白天看见它睁一只眼，闭一只眼，站立在浓密的树枝上，其实这时它正在睡觉呢。猫头鹰的睡觉姿势是不是很另类啊，它这样可是为了时刻监视周围环境防备着敌人的袭击哦!
=================================
鱼也会溺死吗
鱼有鳃，可以在水中呼吸，鱼有鳔，可以在水中自由地沉浮。可是，有人说生活在水中的鱼也会溺死，这是真的吗?
虽然这听起来很荒谬，但却是事实。鱼鳔是鱼游泳时的“救生圈”，它可以通过充气和放气来调节鱼体的比重。这样，鱼在游动时只需要最小的肌肉活动，便能在水中保持不沉不浮的稳定状态。不过，当鱼下沉到一定水深(即“临界深度”)后，外界巨大的压力会使它无法再凋节鳔的体积。这时，它受到的浮力小于自身的重力，于是就不由自主地向水底沉去，再也浮不起来了，并最终因无法呼吸而溺死。虽然，鱼还可以通过摆动鳍和尾往上浮，可是如果沉得太深的话，这样做也无济于事。
另一方面，生活在深海的鱼类，由于它们的骨骼能承受很大的压力，所以它们可以在深水中自由地生活。如果我们把生活在深海中的鱼快速弄到“临界深度”以上，由于它身体内部的压力无法与外界较小的压力达到平衡，因此它就会不断地“膨胀”直至浮到水面上。有时，它甚至会把内脏吐出来，“炸裂”而死。

贪吃孩子变笨
贪吃会降低大脑的血流量
若一次进食过量或一刻不停地进食，会把人体里的大量血液，包括大脑的血液调集到胃肠道来。而充足的血供应是发育前提，如果经常处于缺血状态，其发育必然会受到影响。
贪吃会造成“肥胖脑”
吃得过饱，尤其是进食过量高营养食品，食入的热量就会大大超过消耗的热量，使热能转变成脂肪在体内蓄积。若脑组织的脂肪过多，就会引起“肥胖脑”。研究证实，人的智力与大脑沟回皱褶多少有关，大脑的沟回越明显，皱褶越多，智力水平越高。而肥胖脑使沟回紧紧靠在一起，皱褶消失，大脑皮层呈平滑样，而且神经网络的发育也差，所以，智力水平就会降低。
贪吃会抑制大脑智能区域的生理功能
人的大脑活动方式是兴奋和抑制相互诱导的，即大脑某些部位兴奋了，其相邻部位的一些区域就处于抑制状态，兴奋越加强，周围部位的抑制就越加深，反之亦然。因此，若主管胃肠道消化的植物神经中枢因贪吃过量食物而长时间兴奋，这就必然引起邻近的语言、思维、记忆、想象等大脑智能区域的抑制。这些区域如经常处于抑制状态，智力会越来越差。
贪吃会因便秘而伤害大脑
孩子的零食大多以高营养的精细食品为主，吃了容易发生便秘。便秘时，代谢产物久积于消化道，经肠道细菌作用后产生大量有害物质，容易经肠吸收，进入血液循环，刺激大脑，使脑神经细胞慢性中毒，影响脑的正常发育。
贪吃还会促使大脑早衰
科学家在一项研究中发现，一种能促使大脑早衰的物质——纤维芽细胞生长因子，会因过饱食物而于饭后增加数万倍，这是一种能促使动脉硬化的物质，因而从长远意义上讲，贪吃会使大脑过早衰老。
