近些年，“酸性体质”是“百病之源”的说法引起人们关注，一些商家还推出了号称具有排酸功效的保健食品。“酸性体质”是否引发疾病？“酸碱体质”的说法科学吗？食物能否影响人体的酸碱度？人民日报“求证”栏目记者就此采访了医学专家及营养学家。

In recent years,"acidic"is"The source of basic"That cause people to pay attention to,A few businessmen still are introduced with PaiSuan efficacy as health food."acidic"Whether cause disease?"Acid-base constitution"That science?Food can affect the body's ph value?People's Daily"verification"Column the reporter interviewed the medical experts and nutritionists.

　

　疑问一：“酸性体质”容易致病吗？ Doubt a:"acidic"Easy pathogenic??

　　【回应】 “酸性体质”并非生病原因而是结果。“酸性体质导致肿瘤”是吓唬人 [response] "acidic"Not ill reason but results."Acid constitution lead to cancer"Is scaring people

　　有网文称，中国70%的人由于生活习惯及环境影响，体液pH值在7.35以下，身体处于亚健康状态，是“酸性体质”。“酸性体质”的人容易患严重疾病甚至癌症。这种说法对吗？

Have article said,70% of the Chinese people as a result of life habits and the environmental impact,Humoral pH value in 7.35 the following,The body of sub-health state,is"acidic"."acidic"The people are likely to suffer from serious diseases and even cancer.This kind of statement right?

　　记者在采访中了解到，人体有多种体液，包括细胞内液、细胞外液(血液、组织液和淋巴液)，还有分泌的各种消化液，排泄出的汗液、尿液等。这些液体的酸碱度不同，通常用pH值来衡量。如血液的pH值应该处于7.35—7.45的弱碱状态，低于7.35会引起酸中毒，出现头晕、瞌睡、焦虑，甚至精神错乱；高于7.45会引起碱中毒，出现肌肉痉挛或心脏问题。

Reporter in the interview to understand,The human body has a variety of body fluid,Including the fluid inside cells/Extracellular fluid(blood/Tissue fluid and lymph),And the secretion of various digestive juice,Excreted sweat/Urine, etc.These liquid ph value is different,Usually use pH value to measure.Such as blood pH value should be in an 7.35-7.45 weak base state,Less than 7.35 can cause acidosis,Appear giddy/doze/anxiety,Even insanity;More than 7.45 can cause alkalosis,Appear muscle spasm or heart problems.

　　英国伦敦大学医学博士、武汉大学人民医院内分泌科副主任医师高凌，以及解放军第四五八医院急救中心主任何小华都认为，“酸性体质”导致疾病的说法颠倒了因果关系。实际上，不是“酸性体质”导致疾病，而是患有某种疾病或服了某些药物会导致酸中毒这一结果。

London university medical doctor/Wuhan university people's hospital endocrinology of doctor of vice director of GaoLing,And the people's liberation army DiSiWuBa hospital emergency center director HeXiaoHua all think,"acidic"Lead to disease that upside down causal relationship.In fact,not"acidic"Lead to disease,But with some kind of disease or take some drugs can lead to acidosis the results.

　　武汉协和医院中西医结合科副教授陈瑞表示，导致身体酸度升高的疾病包括代谢性疾病如糖尿病、肥胖、高尿酸血症，消化系统疾病如严重腹泻，呼吸系统疾病如慢性阻塞性肺病、支气管哮喘，泌尿系统疾病如肾功能不全等。这些疾病因为严重影响机体代谢，或者导致代谢终产物排泄障碍，从而导致身体酸度升高。

Wuhan union medical college hospital of combining traditional Chinese and western medicine department associate professor ChenRui said,To cause the body acidity rising diseases including metabolic diseases such as diabetes/obesity/hyperuricemia,The digestive system diseases such as severe diarrhea,Respiratory system diseases such as chronic obstructive pulmonary disease/Bronchial asthma,Urinary system diseases such as kidney function not congruent.These diseases because of the serious influence the body metabolism,Or cause metabolic end product drain disorder,Leading to increased body acidity.

　　医学博士、广州阳普医疗股份有限公司董事长邓冠华认为，“‘大多数人是酸性体质’的观点是错误的”，多数人通常都在正常状态，只有极少数人由于病变导致酸碱度失衡。

Medical doctor/Guangzhou YangPu medical co., LTD., chairman of the board DengGuanHua think,"‘Most people is acidic physique’Point of view is wrong",Most people are usually in the normal condition,Only a few people due to lesions cause ph value imbalance.

　　“‘酸性体质’理论经常靠‘酸性体质导致肿瘤’来吓唬人，但是医学上并没有人体酸碱性和肿瘤诱因有关的说法。”四川省营养学会常务理事、四川大学营养与食品卫生学博士生导师李云说，“酸性体质”理论将因果互换了，事实上，并不是“酸性体质”诱发了肿瘤，而是肿瘤的生长会导致实体瘤周边的微环境变酸。

"‘acidic’Theory often rely on‘Acid constitution lead to cancer’To frighten people,But medical and no human acid alkali and tumor inducement relevant statement."Sichuan nutrition society executive member of the council/Sichuan university nutrition and food hygiene doctoral tutor LiYun said,"acidic"Theory will cause and effect reversed,In fact,And not"acidic"Induced tumor,But the tumor growth can lead to solid tumor microenvironment surrounding the sour.

　

　疑问二：“酸碱体质”说法科学吗？ Question 2:"Acid-base constitution"Statement science??

　　【回应】 中医、西医都没有“酸碱体质”概念 [response] Doctor of traditional Chinese medicine/Western medicine are not"Acid-base constitution"concept

　　何小华救治过不少“酸中毒”病人。他认为“酸碱体质”理论是个伪命题，人的酸碱度主要是指体液，不同体液有不同的酸碱值，如血液偏碱性，而胃液呈酸性。因此，将人类体质简单地划分为“酸性”、“碱性”不科学。

A lot HeXiaoHua treatment"acidosis"The patient.He thinks"Acid-base constitution"Theory is a false proposition,The ph value is mainly refers to body fluids,Different fluid have different ph value,Such as blood alkaline,And the gastric acid.therefore,Will human physical simply divided into"acid"/"alkaline"Don't science.

　　“所谓‘酸碱体质’纯属无稽之谈。”高凌向记者介绍，人体有强大的缓冲系统，如果摄入酸性过多，机体会产生大量碱性成分以缓冲酸性的侵袭并将其中和，反之亦然。即使这些缓冲机制在过量酸性或碱性物质的冲击下被消耗，肺部还可通过呼吸排出二氧化碳减少血液中的酸性成分，肾脏也会通过尿液排出体内的酸性物质，从而维持酸碱度的稳定。

"The so-called‘Acid-base constitution’Utterly ridiculous."GaoLing introduces to the reporter,The human body has powerful buffer system,If intake of acid too much,The body can produce a large number of basic ingredients to buffer acid attacks and these and,And vice versa.Even though these buffer mechanism in excess acidic or alkaline material is under the impact of consumption,The lung can also through the breathing of carbon dioxide reduce the blood's acid composition,Kidney will through the urine discharge body acidity material,So as to maintain the stability of the ph.

　　李云和广东省卫生厅副厅长廖新波都表示，医学理论中并不存在“酸碱体质”或与之类似的概念。

LiYun and guangdong provincial health bureau deputy director manifold new wave have said,Medical theory does not exist"Acid-base constitution"Or like concept.

　　在中医理论中，是否存在“酸碱体质”一说呢？

In the theory of TCM,Whether there is"Acid-base constitution"Say??

　　成都中医药大学医史各家学说教研室副主任章升懋告诉记者，中医学理论中不存在“酸碱体质”的概念。

Chengdu university of traditional Chinese medicine theory, deputy director of the teaching and research section maintains their overseas ZhangSheng told reporters,The theory of traditional Chinese medicine does not exist"Acid-base constitution"concept.

　　武汉大学人民医院中医科主任宋恩峰认为，“严格意义上说，中医不存在酸碱概念”，中医体质学主要是根据中医学阴阳五行、脏腑、精气血津液等确定不同个体的体质差异性，具体分类方法有阴阳分类法、五行分类法、脏腑分类法、体型肥瘦分类法等，并无“酸碱体质”一说。

Wuhan university people's hospital of traditional Chinese medicine department director SongEnFeng think,"Strict sense,The doctor of traditional Chinese medicine does not exist acid-base concepts",The doctor of traditional Chinese medicine physique study mainly according to TCM yin-yang five elements/viscera/Qi-blood and determine the different individual physique difference,Specific classification method have a Yin and Yang classification/Five lines of classification/Viscera classification/Lean body classification, etc,And no"Acid-base constitution"said.

　　“并不是身体的每一个部分都是偏碱性才好。”四川华西医院营养科主任胡雯介绍说，“健康皮肤的pH值应该是呈弱酸性，因为处于弱酸性的皮肤不容易滋生细菌。”

"Not every part of the body is alkaline just good."Sichuan, west China hospital nutrition section head HuWen said,"Healthy skin pH value should be a weak acid,Because in a weak acid skin not easy bacterium."

　　网络上流行的“酸碱体质”检测方法是：用pH试纸测试尿液或口腔酸碱度，从而判断身体酸碱度。李云指出，这种方法不科学，人体酸碱度需通过抽血检查多项生化指标来判断。

Network fashion"Acid-base constitution"Detection method is:Using pH test paper test urine or oral pH value,So as to judge the body ph value.LiYun pointed out that,This method is not scientific,The human body ph value should be through the exsanguinate check many biochemical index to judge.

　　

疑问三：食物会影响身体酸碱度吗？ Question three:Food will influence your body ph value?

　　【回应】 影响微乎其微，人体可自行调节平衡，不要一味追求碱性食物 [response] Negligible influence,The human body can be adjust themselves balance,Don't blindly pursue basic food

　　有网友称，谷类、肉类、蛋类等酸性食物摄入过多可致“酸性体质”，引发慢性病；蔬菜、水果属于碱性食物，能够纠正“酸性体质”，应远离酸性食物，多吃碱性食物。也有保健品营销宣传说，应有意识地服用“排酸”保健品和“碱性”营养剂等。

有Net friend称,grain/meat/Eggs and acidic food intake can cause too much"acidic",Cause chronic disease;vegetables/Fruit belong to basic food,Can correct"acidic",Should be far away from acidic food,Eat more basic food.Also has health products marketing propaganda said,Should be taken in"PaiSuan"Health care products and"alkaline"Nutrition agent, etc.

　　食物有酸碱之分吗？

Food is the acid and alkali points?

　　“在食物的化学研究中，食物可以根据燃烧后所得灰分的化学性质，分为酸性食物和碱性食物。食物灰分是食物燃烧后剩下的一些元素的氧化物，与食物在体内代谢产物的性质是不同的，这些产物有酸性、碱性，还有很多呈中性。血液的酸碱度是各种代谢产物综合平衡的结果，不仅仅由食物燃烧后剩余的几种矿物元素决定。”胡雯说。

"The food in the study of chemistry,Food can according to the burning ash chemical properties,Divided into acidic food and basic food.Food ash is food left after the burning some of the elements of the oxide,And food in the body of the metabolites are quite different in nature,These products are acid/alkaline,There are many is neutral.Blood ph value is all sorts of metabolites comprehensive balance of the results,Not only food by combustion of the rest after several mineral element decision."HuWen said.

　　食物能改变身体的酸碱度吗？

Food can change the body's ph value?

　　武汉协和医院营养科营养师蔡红琳认为，“食物都有一定的酸碱度，但仅仅通过食物很难直接较大幅度地影响人体体液酸碱度。”肉类、乳制品类、谷类等酸性食物被消化分解后，在人体内留下氯、硫、磷等酸性元素；蔬菜、水果等碱性食物被消化分解后，在人体内会留下钠、钾、钙、镁、铁等碱性矿物质。“但是，这些物质很快被机体的缓冲系统改变，从而使机体体液维持在正常范围。”

Wuhan union medical college hospital nutrition division dieticians CaiGongLin think,"Food has certain ph value,But only through the food it is difficult to directly is greatly affect human body fluid ph value."meat/Dairy products/Grains acid food digestion,In the human body left chloride/sulfur/Phosphorus acid element;vegetables/Fruit alkaline food digestion,In the human body will leave sodium/potassium/calcium/magnesium/Iron and alkaline minerals."but,These substances was soon the buffer system change,So that the body fluid to maintain in the normal range."

　　高凌指出，胃液是pH值为1—2的强酸，而胰液是pH值高达8.8的强碱，食物吃到胃里都会变成酸性的，进入肠道后又会被碱性物质中和成碱性。食物经过消化道后，其成分中的酸碱性基本消失，食物分解产生的酸碱性代谢物最多能影响尿液的酸碱度，不会对其他部位的pH值造成影响。他表示，一些药物的确能改变胃肠道、泌尿系统等局部的酸碱度，比如，质子泵抑制剂能抑制胃酸分泌、治疗胃溃疡，碳酸氢钠苏打水能改变痛风病人尿液的酸碱性，使尿酸结晶不易在肾脏沉积，但这些药物并不会导致血液和组织中酸碱度的变化。

GaoLing pointed out that,Gastric juice is pH value is 1, 2 of strong acid,And pancreatic juice is pH value as high as 8.8 strong base,Food to eat to the stomach will become acidic,Into my intestines and will be basic material and into alkaline.Through the digestive tract after food,The components of the acid and alkaline basic disappear,Food down produce acid alkali metabolites can affect most of urine ph value,Not for other parts of the pH value affect.He said,Some drugs can really change the gastrointestinal tract/Urinary system and so on local ph value,For example,Proton pump inhibitor can restrain gastric acid secretion/Treatment of gastric ulcer,Sodium bicarbonate of soda water can change gout patients of urine acid and alkaline,Make uric acid crystals in the kidneys deposit not easily,But these drugs will not lead to blood and tissue ph changes.

　　何小华说，我们提倡多吃青菜、豆腐、水果等碱性食物，其实是需要其中的维生素、粗纤维等营养成分，而不是要获取“碱”成分。

HeXiaoHua said,We advocate to eat more vegetables/tofu/Fruit basic food,Is actually need one of the vitamin/Crude fiber nutrition ingredient and so on,And not to get"alkali"composition.

　　胡雯也强调，蔬菜和水果能够预防慢性疾病的发生，是因为它们含有丰富的维生素、矿物元素、膳食纤维等，而不是所谓碱性的作用。

HuWen stressed,Fruits and vegetables can prevent chronic disease,Because they contain rich vitamin/Mineral elements/Dietary fiber, etc,Not so-called basic role.

　　“酸碱体质”理论还认为，“酸性体质”的人要补充“排酸”产品以达到“酸碱平衡”。对此，湖北省中医院消化科主任医师胡运莲认为，一些宣传可以排酸的“新型保健品”外包装上没有“国食健字”，不属于正规销售渠道，消费者不应盲目购买食用。

"Acid-base constitution"Theory also believe that,"acidic"People need to be added to"PaiSuan"Products in order to achieve"Acid-base balance".this,Hubei institute of traditional Chinese medicine digestive department chief physician HuYunLian think,Some publicity can the PaiSuan"New health care products"On the outer package no"Countries food health word",Do not belong to the normal sales channels,Consumers should not blindly buy food.

　　四川华西医院公共营养师李建告诉记者，“酸碱体质”理论之所以流行，就是因为某些商家为了推销保健品、药品而制造噱头，加上“酸碱平衡”迎合了部分人对待饮食和健康的某种心理，于是便俨然成为一条流行的“医学常识”。

Sichuan, west China hospital public dieticians LiJian told reporters,"Acid-base constitution"Theory is so popular,It is because some businessmen in order to promote health care products/Pharmaceutical and manufacturing stunt,plus"Acid-base balance"Cater to the part to diet and health some psychological,Then the peremptory become a popular"Medical knowledge".

　　“食物应讲求多样化、荤素搭配、平衡膳食。各类食物含有不同的营养成分，相互不可替代。一味追求碱性食物、摒弃酸性食物，并不科学。”李云说。

"Food should be particular about diversification/Element of meat or fish is tie-in/Balance diet.All kinds of food contains different nutrition,Mutual irreplaceable.Blindly pursue basic food/Abandon acid food,Is not scientific."LiYun said.

　　“人们想远离疾病的心情可以理解，但在追求健康之道的过程中，需‘不畏浮云遮望眼’。”高凌表示，在各种不实言论猖獗的现代社会，人们更需要尊重医学，科学养生。均衡的膳食而非在意其所谓的“酸碱性”，以及良好的生活习惯、适量的运动和积极的心态才是身体健康的有力保证。 (本报记者 田豆豆 李 刚 张 文 杨岑、涂晓晨参与采写）

"People want to far away from diseases mood can understand,But in the pursuit of health in the process of the way,Need to‘Not floating clouds screen when observing’."GaoLing said,In all sorts of false speech rampant modern society,People need more respect for medicine,Scientific keeping in good health.A balanced diet and not care about its so-called"Acid alkali",And good living habits/Right amount motion and positive attitude is a powerful guarantee for body health.
