Question:
candy of what the advantages and disadvantages? ? ? ? ?
Answer:
more sugar than smoking is hazardous to the existence of a larger
sweets for us is always a temptation. World Health Organization (WHO) conducted a survey of 23 causes of death in the countrys consumption of sugar high, sugar harm more people have not yet been recognized.
complete rejection is a difficult task sugar, then in their daily lives, we are in the end how much sugar to eat, what kind of sugar is more healthy?
best not more than 40 grams per day
the narrow sense refers to refined sugar, white sugar and food and beverage syrup commonly used in processing. Sugar harm the human body is mainly the latter.
almost all sweet foods are rich in sugar or syrup made with sweeteners. So, for some like to eat sweets, biscuits, snacks, drinks children and young women, the daily intake of more than 100 grams of sugar is a very common thing. However, nutritionists have recommended total daily intake of sugar approximately 30-40 grams, that is, not to exceed the daily intake of total carbohydrates 10%.
30-40 grams of sugar is what is mean? In people who eat sweets, one tablespoon jam of about 15 grams of sugar, a Coke cans at about 37 grams sugar, 3 small pieces of chocolate is about 9 grams of sugar, an ice cream cone is about 10 grams of sugar, a few About 10 grams of sugar cookies if we do not pay attention to words ,30-40 grams of sugar is very easy to break through quantitative restrictions.
too much sugar can cause fracture
refined sugar is very high purity can reach more than 99%, which means that almost no other nutrients which, only a lot of energy. To eat sweets more, people will arise due to intake of too much energy satiety and affect the other rich in protein, vitamins, minerals and dietary fiber intake of food. The long run, will lead to nutritional deficiencies, developmental disorders, obesity and other diseases.
the other hand, the metabolism of sugar in the body need to consume a variety of vitamins and minerals, therefore, often sugar can cause vitamin deficiency, calcium deficiency, potassium deficiency and other nutritional problems. Japan nutritionists that children eat too many sweets is a rise in the rate, causing a fracture of the important reasons; U.S. nutritionists have also pointed out that the children eat sweets fracture is higher.
nutrition survey also found that, although sugar may not directly lead to diabetes, but long-term high consumption of sweets cause excessive insulin secretion, carbohydrate and fat metabolism disorders, disorders caused by the human body environment, thus contributing to a variety of chronic diseases, such as heart cerebrovascular disease, diabetes, obesity, age-related cataracts, dental caries, myopia, the incidence of rickets. Eat sweets will also tend to make human blood acidic, is not conducive to the blood circulation and weakened immune system defenses.
sweet with the drug have the same physiological responses
reluctant to part with sweets also may cause physical and psychological dependence. A study revealed that the human sweet taste after birth the first to accept and pursue the taste of people like to eat sweets are a kind of instinctive reaction.
medical experiments have shown that, in a sense, contains large amounts of sugar, sweets on the brain are similar to the role and effect of drugs. If we allow animals habitually intake of sweets, they stimulate their brains in the production of opioid substances to make them happy. Once stopped the supply of sweets, they will feel pain, irritability, brain chemicals out of balance. This phenomenon of drug addiction is very similar to the reaction.
when the sugar
to eat sweets while a large number of harmful, but if a small amount of food at the right time, health also has certain advantages. For example, the blood glucose concentration decreased when a small amount of sugar can be an emergency supplement. Patients with low blood sugar when you feel hungry black eyes, limbs become soft, the best way is to drink a cup of sugar right away. Delicious breakfast bad people, close to noon, has often feel drowsy and unable to concentrate their attention, decline in thinking ability, when if eat sweets, will be able to quickly restore brain function.
In addition, the sports medicine research confirmed that athletes in strenuous exercise prior to add a small amount of sugary drinks, if you can help them improve their athletic performance; timely complement of sugar after exercise can reduce fatigue. If the bath before the ordinary people, hunger, the need to increase attention, when a small amount of sugar is also beneficial.
brown sugar to eat more healthy
What to eat sugar is optional, if you want to find a balance between sweet and healthy, it is best to eat the following sugars:
brown sugar. It is also called , contains more iron, calcium, potassium, magnesium and other minerals, has a high nutritional value, but also help the body acid-base balance. TCM believes that there is blood circulation scattered silt brown sugar, warm in the cold-dispelling and so on. But the brown sugar and warm, often lit, and parched people should be eating.
oligosaccharides. Such as fructo-oligosaccharides, oligosaccharides lactose, isomaltooligosaccharide so. They heat very low, with the , can promote the growth of beneficial bacteria in vivo, inhibit the proliferation of intestinal pathogens and spoilage bacteria.
sugar alcohol sweeteners. Including xylitol, sorbitol, mannitol, maltitol, etc., slightly lower than sugar sweetness. Their energy is low, does not cause tooth decay, does not increase blood sugar, sweeteners are healthy. The daily consumption better not more than 20 grams, because they will promote intestinal peristalsis, excessive consumption can cause mild diarrhea.

against women eat more sweets big
middle-aged women should not hamper Excessive consumption of sweets, so as to avoid excessive concentration of glucose in the blood, causing hyperlipidemia, arteriosclerosis, obesity, hypertension, coronary heart disease, diabetes and osteoporosis and other diseases, thereby endangering the health. World Health Organization has pointed out:
U.S. researchers found that 50-year-old women to eat sweets too much will lead to gallstones. An excessive amount of sugar into fat itself can affect the normal appetite, prevent vitamins, minerals and other nutrients intake, leading to human obesity. Obesity does not make all people the growth of stones, but for middle-aged women, it is a hotbed of gallstones incurred. Therefore, the middle-aged women to eat sweets.
excess sugar can cause urinary calculi, has been proved by experiments. Sugar in a large number of elderly people, after a sharp increase in the amount of calcium in the urine during this period are easy to form urinary stones. If the day before going to sleep drink a glass of thick syrup, then the risk is even greater risk of urinary stones.
eat sweets but also precipitate breast cancer. According to the research, long-term intake of high sugar foods, make the blood insulin levels often at a high level within the state, and early breast cancer cell growth, is in need of a lot of insulin. Breast absorbed by a large number of insulin, growth and reproduction of breast cancer cells plays a role in fueling.
a long-term sugar overdose, but also accelerate the aging of cells, so that the human ability to adapt the environment is poor, white hair turn yellow. Sugar remain in the mouth, bacteria will be formed by some of the large population of organic acids and enzymes, direct destruction of teeth decalcification, corrosion, the formation of dental caries. Therefore, middle-aged women not to eat sweets.
Answer:
around the world and did not advocate prohibition of sugar, only to promote smoking, how can say that sugar is more harmful than smoking? More sugar is not good, but if the sugar harmful, and that grain, starch, fruits can not eat, and humans to eat?

问题:
糖吃了有什么好处和坏处？？？？？
回答:
多吃糖比吸烟危害更大
甜食的存在对于我们始终是一种诱惑。世界卫生组织（WHO）曾调查了23个国家人口的死亡原因，得出结论：嗜糖之害，甚于吸烟，长期食用含糖量高的食物会使人的寿命明显缩短，并提出了"戒糖"的口号。但是近年来，中国人对糖的消耗量居高不下，吃糖的危害还没有被更多的人认识到。
wq拒绝吃糖是一件困难的事，那么在日常生活中，我们到底该吃多少糖，什么样的糖更健康呢？
每天{zh0}不要超过40克
"糖"的概念有广义和狭义之分。广义的糖指各种可消化的碳水化合物，包括有甜味的糖和没有甜味的淀粉；狭义的糖则指精制后的白糖和食品、饮料加工中常用的糖浆。糖对人体的危害主要是后者。
几乎所有甜味食品中，都含有大量用白糖或糖浆做成的甜味剂。所以，对于一些喜欢吃甜点、饼干、零食、饮料的孩子和年轻女性来说，每天摄入100克以上的白糖是一件很普遍的事情。但营养学家们推荐的每日摄入白糖总量大约为30-40克，即不要超过每日摄入总碳水化合物的10%。
30-40克的白糖是什么概念呢？在人们常吃的甜食中，一大勺果酱约含糖15克，1罐可乐约含糖37克，3小块巧克力约含糖9克，1只蛋卷冰激凌约含糖10克，几块饼干约含糖10克……如果不加注意的话，30-40克糖的数量限制非常容易突破。
吃糖过多会导致骨折
精制后的白糖纯度非常高，能达到99％以上，这就意味着其中几乎不含其他营养物质，只有大量能量。吃甜食多了，人就会因摄入能量太多而产生饱腹感，影响对其他富含蛋白质、维生素、矿物质和膳食纤维食品的摄入。长此以往，会导致营养缺乏、发育障碍、肥胖等疾病。
另一方面，白糖在体内的代谢需要消耗多种维生素和矿物质，因此，经常吃糖会造成维生素缺乏、缺钙、缺钾等营养问题。日本营养学家认为，儿童吃甜食过多是造成骨折率上升的重要原因；美国营养学家也指出，爱吃甜食的孩子骨折率较高。
营养调查还发现，尽管吃糖可能并不直接导致糖尿病，但长期大量食用甜食会使胰岛素分泌过多、碳水化合物和脂肪代谢紊乱，引起人体内环境失调，进而促进多种慢性疾病，如心脑血管疾病、糖尿病、肥胖症、老年性白内障、龋齿、近视、佝偻病的发生。多吃甜食还会使人体血液趋向酸性，不利于血液循环，并减弱免疫系统的防御功能。
嗜甜与xd有同样的生理反应
贪恋甜食还可能造成生理和心理上的依赖。据研究表明，甜味是人类出生后首先接受和追寻的味道，喜欢吃甜食是人的一种本能反应。
医学实验证明，从某种意义上来说，含有大量白糖的甜食对大脑的作用和dp有异曲同工之效。如果让动物习惯性地摄入甜食，就会刺激它们大脑中类阿片类物质的产生，令它们感到快乐。一旦停止甜食供应，它们就会感到痛苦、烦躁不安、大脑中的化学物质失去平衡。这种现象与dp上瘾的反应非常类似。
什么时候该吃糖
大量吃甜食虽然有害，但如果少量并在合适的时候食用，对健康也具有一定的好处。比如，血糖浓度降低的时候，少量吃糖可以紧急补充。低血糖患者饥饿时会感到眼前发黑、四肢发软，{zh0}的办法就是马上喝一杯糖水。不好好吃早饭的人，临近中午时常会感到昏昏沉沉、注意力不能集中、思维能力下降，这时如果吃点甜食，就能快速恢复大脑功能。
此外，运动医学研究证实，运动员在剧烈运动前如果补充少量含糖饮料，可以帮助他们提高运动成绩；运动之后及时补糖，可以xc疲劳。普通人如果在洗澡前、饥饿时、需要提高注意力时少量吃糖，也有好处。
吃红糖更健康
吃什么糖是可以选择的，如果希望在甜食和健康之间找到平衡，{zh0}吃以下几种糖：
红糖。它也叫"黑糖"、"褐糖"，含有较多的铁、钙、钾、镁等矿物质，具有很高的营养价值，而且有利于人体内酸碱平衡。中医认为，红糖有hx散淤、温中散寒等作用。但是红糖性温，经常上火、口干舌燥的人应当少吃。
低聚糖。如低聚果糖、低聚乳糖、低聚异麦芽糖等。它们的热量很低，具有"调整生态平衡"的作用，有的被称为"双歧因子"，能促进体内有益菌的生长，抑制肠道致病菌和腐败菌增殖。
糖醇类甜味剂。包括木糖醇、山梨糖醇、甘露糖醇、麦芽糖醇等，甜度略低于白糖。它们能量低、不会引起龋齿、不升高血糖，属于健康甜味剂。但每天的食用量{zh0}别超过20克，因为它们会促进肠道蠕动，过量食用能引起轻度腹泻。
=================================
女性多吃甜食危害大
中老年女笥不宜过多食用甜食，以免使血中葡萄糖浓度过高，引起高脂血症、动脉硬化、肥胖症、高血压病、冠心病、糖尿病和骨质疏松等疾病，从而危及健康。世界卫生组织曾指出：“嗜糖比嗜烟更加可怕。长期嗜高糖食物的人，其平均寿命比正常饮食的人缩短10-20年。”
美国科研人员发现，50岁左右的妇女吃甜食过多，会导致胆结石。过量的糖还能自行转化为脂肪，影响正常的食欲，妨碍维生素、矿物质和其他营养成分的摄入，导致人体肥胖。肥胖并不会使所有的人生长结石，但对中年妇女来说，它却是招致胆结石的温床。因此，中老年妇女要少吃甜食。
吃糖过量会引起尿石症，已被实验所证明。老年人在一次大量吃糖后，尿中含钙量急剧增加，这期间容易形成尿结石。如果每天临睡前喝一杯浓糖水，则患尿结石的危险就更大。
多吃甜食还可促发乳腺癌。据研究，长期摄入高糖食物，能使血内胰岛素含量经常处于高水平状态，而早期乳腺癌细胞的生长，正需要大量的胰岛素。被乳房大量吸收的胰岛素，对乳腺癌细胞的生长繁殖，起着推波助澜的作用。
长期食糖过量，还会加速细胞的老化，使人体环境适应能力差，头发变黄变白。糖留在口腔内，xj就会大量繁殖而形成一些有机酸和酶，直接破坏牙齿，使牙齿脱钙、腐蚀，形成龋齿。因此中老年女性不宜多吃甜食。
回答:
世界范围内并没有提倡禁糖，只有提倡禁烟，怎么能将糖说成比抽烟更有危害？多吃糖是不好，但如果糖有害，那谷物、淀粉类、水果类不能吃了，人类吃什么？
