A | 过量摄入含糖饮料导致的心血管疾病和糖尿病死亡的负担尤为突出。在过去30年中,因缺血性心脏病和糖尿病死亡的人数分别增加了95%和94%。 A sizable piece of trash discovered in the middle of a sheep pasture in Eastern Australia's New South Wales may be space debris from a SpaceX mission and connected to a loud blast reported in early July in the area, Australian ABC News has reported.,According to the report, numerous people who heard the sound on July 9 turned to social media to report it from as far away as Albury, Wagga Wagga, and Canberra to the Snowy Mountains in southern New South Wales.,An extraordinary nearly three-meter-high object was reported by farmer Mick Miners, who runs a sheep farm at the remote area of Numbla Vale.,"I didn't know what to think, I had no idea what it was," he told the outlet, while his neighbor, Jock Wallace, who also stumbled upon strange debris said he "didn't hear the bang, but my daughters said it was very loud. I think it's a concern it's just fallen out of the sky. If it landed on your house it would make a hell of a mess.",As we all wait for the Chinese booster to impact-Here’s some photos of pieces believed to be from SpaceX’s Crew-1’s Trunk, which landed in Australia on July 9th, but discovered in farmland on July 25thThese are large pieces; which could be dangerous & fatal & more frequent. pic.twitter.com/ImaO4YKQzL— Earth Consuming Mike (@LCS_Big_Mike) July 29, 2022,Serial numbers were seen on one of the items discovered on his premises. Astrophysicist Brad Tucker from the Australian National University College of Science reportedly claimed that the debris was most likely from the craft's unpressurized crew trunk.,SpaceX's Crew Dragon Lifts Off for Its First Operational Mission to ISS16 November 2020, 00:29 GMT,He said that it might be the biggest piece of debris to have been found in Australia since NASA's Skylab space station crashed to Earth above Esperance, Western Australia, in 1979.,"In photographs of the debris you can clearly see charring, which you would expect from re-entry," Tucker told the outlet last Friday. "It is very rare to see, because they don't usually land on land, but in the ocean.",I just got back from Dalgety, NSW. I was busy confirming that parts of a @SpaceX Crew-1 Trunk capsule crashed into a few paddocks in rural NSW!

According to the expert, the craft was probably traveling at 25,000 kilometers per hour when it made re-entry and left behind debris, and it was probably responsible for the July 9 blast heard by many people in the area.,This Monday, in an interview on a local radio, quoted by the Daily Mail, Tucker confirmed that the debris belonged to the Crew-1 SpaceX mission spacecraft.,"This is most definitely space junk which was part of the SpaceX Crew-1 trunk," he is quoted as saying. "SpaceX has this capsule that takes humans into space but there is a bottom part... so when the astronauts come back, they leave the bottom part in space before the capsule lands.",The component, most likely made of aluminum and carbon composites, has been in orbit since November 2020, according to the expert.,"There was a plan of having it come down on Earth and purposely hitting the Earth's atmosphere so it would break apart and land in the ocean," he said.,It took some time to find the object, according to Tucker, because it had fallen far from Miners' house.,"From a distance it looks like a tree almost, like a burnt tree, and then you get closer and you realise 'hey that's not right'," Tucker explained.。看到这儿,是不是点奶茶的手微微颤抖,奶茶或者其他含糖饮料还能喝吗?01、糖是什么,有什么作用?先不一棍子把糖给打死,我们得看看糖到底有什么作用。糖类是在自然界中广泛存在的一类有机化合物,又叫做碳水化合物,它包括蔗糖、葡萄糖、果糖、半乳糖、乳糖、麦芽糖、淀粉等。在这些糖中,除了葡萄糖、果糖和半乳糖能被人体直接吸收,其余的糖都要在体内转化为基本的单糖后,才能被吸收利用。比如馒头中含有大量淀粉,淀粉在我们口腔中咀嚼时,会刺激口腔的唾液腺产生唾液淀粉酶。在唾液淀粉酶的作用下,淀粉被水解成麦芽糖,所以我们吃馒头时会尝到甜味。然后麦芽糖进入小肠,被小肠腺分泌的麦芽糖酶进一步分解为葡萄糖,从而被身体吸收。糖的主要功能是为人体提供能量,每克葡萄糖在人体内氧化分解可产生4千卡能量,而人体所需要的70%左右的能量也由糖提供。此外,糖还是构成细胞和组织的重要成分,是维持人体代谢和免疫功能不可或缺的重要物质。02、为什么摄入过量的糖“有害”?上文已经提到,糖是我们生命活动所必须的,所以我们离不开它,但是一旦摄入糖过多,它又会对身体造成不小的负面影响,具体有以下这些:1)如果摄取过量糖分而无法及时消耗,多余的热量就会转化成脂肪。简单来讲,就是会长胖。

B | 2)吃糖过多,会使人产生饱腹感,从而影响正常进食,导致多种营养素的缺乏。如果儿童长期高糖饮食,会直接影响儿童骨骼的生长发育,导致佝偻病等疾病。

C | 并且如果吃含糖食品或饮料过多,又不注意口腔卫生,会为口腔内的细菌提供生长繁殖的良好条件,容易引起龋齿和口腔溃疡。3)加重肝脏的负担。肝脏是调节血糖浓度的主要器官,如果过量摄入糖,为了保持血糖浓度稳定,肝脏会将糖转化为脂肪,容易诱发脂肪肝。4)摄糖过多会引起一系列代谢功能紊乱。糖、脂肪、蛋白质是人体新陈代谢的三大基础物质,高血糖导致糖代谢紊乱,打破了系统代谢平衡,进而往往导致脂、蛋白代谢紊乱,致使整个代谢系统出现问题。血糖升高还会使血液黏稠度增加,减慢血流运行速度,会使血管变细、变脆、弹性降低,导致血流不畅、血管堵塞,从而导致冠心病、脑梗、中风等疾病的风险大大增加。另外特别要提到一点,如今各大城市遍布大大小小的奶茶店,但众多的调查都显示即使是号称完全不含糖的奶茶,其含糖量也往往不低。03、如何避免摄入过量糖?《中国居民膳食指南(2022)》中提出,成年人需要控制添加糖的摄入量,每天不超过50克,最好控制在25克以下。在生活中,想要避免摄入过量糖,可以注意以下几点:1)不主动喝含糖饮料。少喝果汁,尽量选择吃新鲜水果。2)少吃话梅等果脯,减少“隐形糖”的摄入。很多加工过的零食为了防止变质,会加入大量的糖抑制细菌生长。3)少吃膨化食品。它们吃起来虽然并不一定是甜的,但里面含有大量的淀粉,却不含有抑制糖上升的膳食纤维。

D | 4)做饭时少用番茄酱、烧烤汁等调味酱,这些调味剂每100克大概有15克左右的糖。5)“低糖”和“无糖”的食物也不建议过多食用。“无糖”不代表完全没有糖,其实是指不含添加糖,比如蔗糖、麦芽糖、果糖等,取而代之的是木糖醇这类代糖。虽然热量低了,但是有研究表明代糖饮料也可能增加首次新发心血管疾病的风险,糖醇类代糖过量摄入可能引起腹泻。
