最近,網(wǎng)上有個(gè)熱門(mén)視頻迅速躥紅,甚至成為微博熱門(mén)話題,內(nèi)容是搬運(yùn)國(guó)外的一個(gè)唬人視頻,內(nèi)容是說(shuō)低碳水生酮飲食有「五大危害」。 事實(shí)果真如此嗎?No! 視頻中聲稱的所有「危害」都是假的。今天,我們就說(shuō)原理、擺證據(jù)、列事實(shí),掰扯掰扯這個(gè)非常有誤導(dǎo)性的熱門(mén)視頻。 另外,生酮飲食有一項(xiàng)真正的「危害」,熱門(mén)視頻中卻沒(méi)說(shuō)。文末,我們會(huì)為你解析。 誤區(qū) 01 低碳水生酮 0000000 會(huì)缺維生素、礦物質(zhì)? 0000000 真相:低碳水生酮飲食不僅不會(huì)缺乏任何維生素、礦物質(zhì),反而是真正的高營(yíng)養(yǎng)密度飲食方案。 這是因?yàn)?,低碳水生酮飲食要求戒除或限制的是糖、面、米等富含精制碳水化合物的食物?span>而不必限制大多數(shù)蔬菜和低糖水果,熱門(mén)視頻中的內(nèi)容是存在事實(shí)錯(cuò)誤的。 此外,維生素、礦物質(zhì)最重要的食物來(lái)源是肉類、魚(yú)類、蛋類、動(dòng)物內(nèi)臟、優(yōu)質(zhì)脂肪等,而不止有蔬菜水果。 低碳水生酮飲食推薦吃肉類、魚(yú)類、蛋類、動(dòng)物內(nèi)臟、優(yōu)質(zhì)脂肪、低糖蔬菜水果和堅(jiān)果,所以,不僅不會(huì)缺乏任何維生素、礦物質(zhì),反而是真正的高營(yíng)養(yǎng)密度飲食方案。 科學(xué)研究也證實(shí)了生酮飲食不會(huì)缺營(yíng)養(yǎng)。例如,今年 10 月剛剛發(fā)表的一篇隨機(jī)對(duì)照試驗(yàn)研究(高質(zhì)量研究)證明:低碳水飲食不會(huì)導(dǎo)致任何營(yíng)養(yǎng)缺乏。 相同結(jié)論的科研論文還有很多: 誤區(qū) 02 低碳水生酮 0000000 會(huì)降低運(yùn)動(dòng)體能? 0000000 真相:適應(yīng)后,不僅不會(huì)降低運(yùn)動(dòng)體能,反而可能提高! 從事實(shí)來(lái)看,大量頂級(jí)運(yùn)動(dòng)員倡導(dǎo)低碳水生酮飲食,從 NBA 湖人隊(duì)大批球星、格斗運(yùn)動(dòng)員「嘴炮」、超馬世界冠軍等等,都是低碳水的擁護(hù)者。 (圖左為綜合格斗運(yùn)動(dòng)員「嘴炮」) 實(shí)際上,擼鐵愛(ài)好者都知道的傳奇健身組織 CrossFit 也大力倡導(dǎo)低碳水飲食,他們的運(yùn)動(dòng)飲食哲學(xué)就是「控碳水、邁開(kāi)腿」(Off the Carbs, Off the Couch)。 視頻里自己也說(shuō),低碳水生酮飲食的倡導(dǎo)者,大多是專業(yè)運(yùn)動(dòng)員。 也就是說(shuō),視頻提出一個(gè)「猜想」:低碳水會(huì)降低運(yùn)動(dòng)體能,盡管很多專業(yè)運(yùn)動(dòng)員都倡導(dǎo)低碳水飲食,用「事實(shí)」證明低碳水的好處,視頻依然認(rèn)為自己的猜想是對(duì)的。 那么,科學(xué)研究怎么說(shuō)呢? 大量科學(xué)研究表明,一旦適應(yīng)以后,低碳水生酮飲食不僅不會(huì)降低運(yùn)動(dòng)體能表現(xiàn),反而可能提高耐力、減少疲勞和損傷。 也就是說(shuō),低碳水初期,飲食改變會(huì)導(dǎo)致適應(yīng)性反應(yīng)。等這個(gè)適應(yīng)期度過(guò)以后,體能就會(huì)逐步改善。 視頻里自己也說(shuō),適應(yīng)期癥狀會(huì)在及天之內(nèi)消失。 ![]() 誤區(qū) 03 低碳水生酮 0000000 效果更容易反彈? 0000000 ![]() 真相:低碳水生酮并不容易反彈,可能更容易堅(jiān)持。 視頻中聲稱,低碳水生酮的效果「可能會(huì)」反彈。 太可笑了!要知道,任何減肥方式,如果錯(cuò)誤操作、恢復(fù)到之前不健康的生活方式,都一定會(huì)反彈。但是沒(méi)有任何證據(jù)表明,低碳水生酮比其他減肥方式更難堅(jiān)持、更容易反彈。 相反,有科學(xué)研究和大量現(xiàn)實(shí)案例證明,通過(guò)低碳水生酮飲食減肥成功、改善健康的人群,很多是愿意長(zhǎng)期遵循的,因?yàn)榇蠹艺嬲媲星械乜吹搅俗约荷钯|(zhì)量的提高,而且并沒(méi)有想象中那么難。 ![]() 如果說(shuō)生酮飲食真的「難堅(jiān)持」,那么最大原因,應(yīng)該是不斷有人妖魔化這種飲食,讓本來(lái)有機(jī)會(huì)嘗試堅(jiān)持的人也失去了勇氣和動(dòng)力。 誤區(qū) 04 低碳水生酮 0000000 會(huì)掉肌肉、掉代謝? 0000000 ![]() 真相:低碳水飲食不僅不會(huì)掉肌肉,反而可以防止肌肉流失。 視頻聲稱,低碳水生酮飲食會(huì)導(dǎo)致掉肌肉、掉代謝,理由是「低碳水飲食蛋白質(zhì)吃得少,所以會(huì)掉肌肉」。這不是睜著眼說(shuō)瞎話嗎!低碳水生酮飲食提倡吃肉類、蛋類、魚(yú)類等食物,根本不缺蛋白質(zhì)。 科學(xué)研究表明,低碳水飲食不僅不容易掉肌肉,反而比常規(guī)的「限制卡路里」更容易保存肌肉!科學(xué)家早就發(fā)現(xiàn),在減脂過(guò)程中,低碳水飲食具有防止肌肉分解流失的作用。 ![]() 誤區(qū) 05 低碳水生酮 0000000 增加健康風(fēng)險(xiǎn)? 0000000 ![]() 真相:低碳水生酮不僅不會(huì)增加健康風(fēng)險(xiǎn),反而可以防治代謝疾病。 視頻聲稱,低碳水生酮增加健康風(fēng)險(xiǎn),這完全是顛倒黑白!他們認(rèn)為,低碳水飲食吃優(yōu)質(zhì)脂肪太多,會(huì)導(dǎo)致人們更容易患上糖尿病、中風(fēng)、心力衰竭和癌癥等疾病。 但是,事實(shí)和科學(xué)研究再次無(wú)情地打了他們的臉!大量研究和事實(shí)案例表明,低碳水生酮飲食不會(huì)導(dǎo)致這些疾病,反而可以預(yù)防、改善甚至逆轉(zhuǎn)! ![]() 原因之一是,「代謝綜合征」和慢性炎癥是導(dǎo)致糖尿病、中風(fēng)、心臟病、癌癥等多種慢性疾病的最重要風(fēng)險(xiǎn)因素,而低碳水生酮飲食可以有效逆轉(zhuǎn)代謝綜合征,同時(shí)降低慢性炎癥,因此有著非常大的健康益處! ![]() 事實(shí)上,低碳水生酮飲食的諸多健康益處,不僅出現(xiàn)在越來(lái)越多的前沿科學(xué)文獻(xiàn)里,更是已經(jīng)被眾多醫(yī)學(xué)專家認(rèn)可和倡導(dǎo)。 上個(gè)月「第二屆全國(guó)低碳醫(yī)學(xué)大會(huì)」在深圳召開(kāi),眾多國(guó)內(nèi)外頂尖專家齊聚一堂,大會(huì)的主題就是:倡導(dǎo)低碳生活,防治代謝疾病。 ![]() (周華博士、石漢平教授、殷峻教授、楊乃龍教授) 真正的「危害」 0000000 似乎只有一個(gè)…… 0000000 低碳水生酮飲食最大的危害,就是它太有「顛覆性」了——它挑戰(zhàn)了傳統(tǒng)健康觀念的刻板教條,并觸碰了大型食品、醫(yī)藥資本的利益。 因此,傳統(tǒng)專家、流量媒體、大型資本既不愿深入研究,也不想承認(rèn)錯(cuò)誤。 傳統(tǒng)專家不愿深入研究,因?yàn)槌杀緲O高; 流量媒體不愿深入研究,因?yàn)榱髁刻停?/p> 食藥資本不愿深入研究,因?yàn)樘y賺錢(qián)。 那些想要改善肥胖、代謝健康的人,本來(lái)想要學(xué)習(xí)低碳水健康知識(shí),滿眼看到的卻是主流專家不經(jīng)研究就盲目反對(duì)、流量媒體不經(jīng)研究就盲目抨擊。同時(shí),超市里滿滿都是方便又美味的高碳水食物,反正吃病以后還可以吃藥尋求安慰,就沒(méi)有動(dòng)力去了解真正的健康飲食了。 就這樣,錯(cuò)誤觀念發(fā)展壯大、不斷傳播,腐敗專家、流量媒體、貪婪資本都樂(lè)在其中,看上去歲月靜好。如果錯(cuò)誤觀念一直盛行,耽誤的將是無(wú)數(shù)普通人的健康和生命質(zhì)量。 好在,越來(lái)越多的嚴(yán)謹(jǐn)專家、良心媒體、創(chuàng)新型企業(yè)和先鋒讀者在不斷努力,用理論邏輯、科研證據(jù)、事實(shí)案例和優(yōu)質(zhì)產(chǎn)品證明這種飲食是安全、健康的。我們期待,每個(gè)人可以自由學(xué)習(xí)健康知識(shí)、輕松遵循健康生活方式的時(shí)代早日來(lái)臨! 如果你也感受到低碳水帶來(lái)的益處,歡迎在評(píng)論區(qū)分享給大家。 參考文獻(xiàn): [1] Venables MC, Achten J, Jeukendrup AE: Determinants of fat oxidation during exercise in healthy men and women: a cross-sectional study.
