你是否有过这样的困扰:明明吃了早餐,不到中午就饿得心慌手乱?问题出现在哪里呢?
科学研究发现,早餐蛋白质摄入不足,不仅让人饿得更快,还可能会导致全天能量摄入超标,从而更容易发胖。Theresearch

早餐蛋白质没吃够可能会带来两个问题▌全天热量超标,饮食质量下降国际期刊《肥胖》曾追踪近万名中年人长达13个月,发现一个有趣现象:早餐蛋白质比例高的人,全天摄入的总热量更低,且更倾向于选择健康食物;而早餐蛋白质不足的人,则会不自觉地在后续餐食中补偿性摄入更多高糖、高脂肪食物,甚至酒精。科学家将这种现象称为“蛋白质杠杆作用”——早餐欠下的蛋白质“债”,会促使身体全天疯狂寻找高热量食物填补空缺,仿佛身体在警告你:“营养不够,快补回来!”Accordingtotheproteinleveragehypothesis,individualswhoconsumeahigheramountofproteinatbreakfasttendtoconsumefewercaloriesthroughouttheday.Theyalsoshowapreferenceforhealthierfoodchoices.Conversely,thosewhodon'teatenoughproteinduringbreakfasttendtocompensatebyconsumingmoresugaryandhigh-fatfoodsduringsubsequentmeals.▌体重失控风险增加一项针对超重青少年的实验显示:每天吃35克高蛋白早餐的组别,12周后平均减掉0.4公斤纯脂肪,全天自动少摄入近400大卡(相当于一顿正餐);而普通早餐或不吃早餐的组别,体重不降反升,甚至出现“越饿越想吃零食”的恶性循环。早餐吃多少蛋白质才够?
根据《中国居民膳食指南》,成年人每日蛋白质推荐量为女性55克、男性65克。若以早餐占比30%计算,女性需至少16.5克,男性19.5克。但若想实现控体重、稳血糖的效果,研究建议将早餐蛋白质提升至25克左右。蛋白质消化慢,饱腹感强,有利于控制体重和体脂。另外,根据2023年发表在《生理学报告》一篇关于高蛋白饮食与胰岛素分泌的综述,蛋白质会促进胰岛β细胞分泌胰岛素,胰岛素有利于降血糖,这样血糖就不会在餐后大起大落。可见,早餐增加一定比例蛋白质,有利于血糖的稳定。Proteintriggersthereleaseofinsulinbypancreaticβ-cells,whichhelpsinregulatingpost-mealglucoselevels,therebypreventingdrasticfluctuationsinbloodsugarlevels.Therefore,increasingtheamountofproteinconsumedduringbreakfastsignificantlycontributestomaintainingstablebloodsugarlevels.Therecommendedamountofproteinoneshouldhaveatbreakfasttoachieveoptimalweightmanagementandglycemiccontrolisaround25grams.问题来了!早饭怎么吃,可以达到25g以上的量呢?首先,我们得知道哪些食物的蛋白质丰富。这些食物,可以作为早餐的备选,再从这些食物中抽出不同类型来进行组合,以保证我们每顿早餐摄入25g蛋白质,同时兼顾到饮食多样化。奶蛋肉鱼、豆类、谷物类等蛋白质含量都不少,其中豆类的蛋白质虽然是植物蛋白,但消化吸收率高,属于优质蛋白。Dairy,eggs,meat,fish,legumesandgrainsareexcellentsourcesofprotein.Notably,whilelegumesofferplant-basedprotein,theirhighdigestibilityandabsorptionrateclassifythemashigh-qualityproteinsources.根据国人的早餐习惯,我们总结了几类优质蛋白质来源食物,大家可以根据需求进行组合。►肉蛋类对于早餐,不仅要吃够蛋白质,更要吃得丰富,一顿营养充足的早餐通常应该包括4类食物:❶谷薯类:如馒头、花卷、米饭等,主要提供碳水化合物、蛋白质、维生素和矿物质,是能量最经济的来源。❷肉蛋类:如蛋、猪肉、鸡肉、牛肉、鱼肉等,主要提供脂肪和蛋白质和多种维生素、矿物质。❸奶豆类:如纯牛奶、酸奶、豆浆等,主要提供优质蛋白质、维生素和矿物质。❹果蔬类:如西红柿、黄瓜、菠菜、苹果、香蕉等,主要提供多种维生素和矿物质。Whiletheemphasisisonproteinintake,awell-roundedbreakfastshouldincludefouressentialfoodgroups:grains,meatandeggs,dairyandlegumes,fruitsandvegetables.Additionally,adequatecarbohydrateconsumptioniscrucialasitprovidesthebrainwithsufficientenergy,makingstaplefoodsparticularlyimportantforchildrenandadultswithhighcognitivedemands.而且,早餐还要注意必须摄入足够的碳水化合物,这样才能给大脑提供充足的能量,所以,孩子和脑力为主的上班族们更要好吃主食题目:Theresearch

图片中,橘子表面布满绿毛和黑斑,明显已经变质。部分卖家在商品描述中宣称发霉橘子可用于生物、化学实验,有的直接描述为“适合做实验用”。发霉橘子为何会成为二手平台“香饽饽”?接触发霉的橘子会带来哪些健康隐患?Recently,abizarretrendofsellingmold-riddenorangesatjaw-droppingpriceshassweptonsecond-handplatforms,withsingledecayingfruitsbeinglistedforupto388yuan–over100timestheiroriginalvalue.Photosshowcitrusspecimensblanketedingreenandblackfungalcolonies,marketedas"idealforbio-chemicalexperiments"bysellers.网购平台真的可以买到正规实验耗材吗?
据央视新闻报道,在二手物品交易平台搜索关键词“发霉的橘子”,出现多个标价数百元的售卖链接。其中一个标价388元的售卖链接显示,有上百人想要,上万人浏览,商家宣称“全身裹满了霉菌,可用来研究”。
平台上多个售卖链接中均提到,“适合做科学实验,特别是生物、化学类实验”。一位医学类研究生告诉记者,正规的实验耗材有供应商,不会从网购平台采购。Onasecond-handplatforms,searchresultsfor"moldyoranges"revealmultiplelistingswiththousandsofviews.Oneviralpostadvertisinga"fullymold-coatedresearchspecimen"attractedover100seriousinquiries.Sellersdefinitelytargetscienceenthusiasts,claimingthesefungalcoloniescouldaidlaboratorystudies.长期从事微生物研究的科研工作者郭建伟表示,研究各种条件下导致橘子发霉的青霉菌种类,并筛选抑制主要霉变青霉的植物精油等保鲜剂,是有价值的。但是社交平台卖的发霉橘子,由于掺杂利益,商家不会如实告诉研究者橘子的品种、产地、运输冷藏条件,这就会导致研究的结果不可靠,影响筛选保鲜剂的应用效果。
平台相关人员对记者表示,商品链接上的价格,并不是实际成交价,更多是防拍价,“也可能是给自己引流的一种手段。”
当然,并不排除有些发霉水果确实能给科研人员带来帮助。如2024年,中国科学院科研人员得到一颗长蘑菇的苹果,用于研究菌的生长情况。A2024ChineseAcademyofSciencesstudydiduseamushroom-growingappleformycologyresearch,legitimatescientistsacquirespecimensthroughcertifiedsuppliers,notonlinemarketplaces.但这种发霉水果需求量有限,交易平台上也能看到,成交量很低。而且,在“养霉菌”过程中,还可能给自己带来安全隐患。
专家提示:发霉水果或致肺部感染应尽快处理
北京工商大学食品营养与健康系副主任侯殿志建议,家中如有发霉的食物,应尽快处理掉,否则会带来健康隐患。
专家介绍,发霉水果上的“绿毛”,其实是各种霉菌。正常情况下,肉眼是看不见霉菌的,如果能看到,说明霉菌数量已经很多了,而且霉菌会在烂水果的果肉中蔓延。如果水果表面已发霉腐烂,应整个扔掉,切掉发霉部分也不能吃。同时,尽量别用手摸。
之前还有人在网上晒出会“冒烟”的橘子,觉得“仙气飘飘”很好玩。其实,这是霉菌繁殖产生的孢子在扩散,如果飘散到其他食物或厨房用具上,会导致更多食物变质。通过空气传播,这些孢子还可能被吸入肺部。Thetrendhasspawnedaparallelhealthawarenesscampaignunderthehashtagmoldyorangesmaycauselunginfections.Respiratoryspecialistsexplainthathandlingsuchfruitsrisksinhalingaspergillusandpenicilliumspores,whichcantriggercoughingfitsorevenfungalpneumoniainimmunocompromisedindividuals.Healthauthoritiesurgethepublictoabandonmoldyfruitsentirely,notingthatcuttingawayvisibledecayd
