DNA meaning

DNA meaning 

https://share.google/aimode/OIqF1hLKjqc5mgnBW

=====

DNA stands for deoxyribonucleic acid, the hereditary molecule inside cells that carries the genetic instructions used in the growth, development, functioning, and reproduction of all living organisms. [1, 2, 3]

Structure

  • Double Helix: DNA looks like a twisted ladder, a shape known as a double helix.
  • Backbone: The sides of the ladder are made of alternating sugar (deoxyribose) and phosphate molecules.
  • Base Pairs: The rungs of the ladder are formed by four chemical bases connected by chemical bonds: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). [1, 4]

Function

  • Genetic Code: The exact sequence of these four bases spells out the instructions—like a recipe book or blueprint—for making proteins, which build and run the body.
  • Heredity: DNA is passed down from biological parents to their children, determining traits like eye color, height, and hair type.
  • Replication: DNA can copy itself during cell division so that every new cell gets a full set of instructions. [2, 5, 6, 7, 8, 9]

=====
=====

"Maxed out" most commonly refers to reaching the absolute limit of something, such as exhausting a credit card's spending limit, hitting a physical or hardware capacity, or the popular 2024 country song by Bayker Blankenship on Spotify. [1, 2]

Meaning and Usage Categories

  • Financial Limits: Spending the total amount allowed on a credit card or bank account so no more purchases can be made.
  • Physical and Performance Peaks: Reaching the maximum capability of a vehicle's speed, a weight lifted during exercise, or data transmission speeds.
  • Hardware and Capacity Caps: Filling every available slot on a computer or phone with the largest possible storage device.
  • Colloquial Expressions: Reaching a psychological maximum, such as being 100% stressed or embarrassed. [1, 3, 4, 5, 6]

Notable Cultural References

  • Bayker Blankenship Song: A viral country/folk track titled "Maxed Out" on YouTube released in 2024, detailing hard times and financial struggles.
  • Documentary Film: Maxed Out on IMDb, a 2006 documentary by James Scurlock focusing on predatory lending practices and American debt. [7, 8, 9, 10]

全国营养调查: 八成国人控糖有成 - 95%国人钠超标 - 相等于日吃两茶匙盐




全国营养调查

八成国人控糖有成

95%国人钠超标

相等于日吃两茶匙盐

=====

  全国营养调查结果显示更多国人有效控糖,约八成的国人去年的每日糖摄取量在建议范围,但钠、卡路里和脂肪摄取量不减反增,尤其钠的日均摄取量竟超标一倍,相等于每天吃下两茶匙的盐,现象值得关注。

  社会政策统筹部长兼保健卫生部长王乙康今天在新加坡心脏基金的世界心脏日活动上致辞时,公布《2025年全国人口健康调查》与《2025年全国营养调查》的主要结果。

  全国营养调查的部分由保健促进局于去年6月至12月间进行,共调查了约3000名18岁至69岁的本地居民的膳食结构与营养摄取状况。

  调查显示,国人在控糖方面取得显著成效,糖摄取量有所减少,尤其是含糖饮料的部分。

  每日糖摄取的建议量约为50克,相等于10茶匙的糖。结果显示,国人去年每日平均糖摄取量从2018年的60克及2022年的56克,进一步下降至48克,达到了建议范围。摄取量在建议范围的国人比例,也从2019年的61%大幅提升至79%,也就是每五个人当中,就有四个符合标准。

  这显示当局2022年落实的营养等级(Nutri-Grade)标签计划有效。

  然而,国人的钠、卡路里和脂肪摄取量却呈上升趋势,尤其以钠最为严重。

钠摄取量比每日建议高出一倍

  根据调查,国人每日平均的钠摄取量从2019年的3480毫克激增至去年的4000毫克,这相当于每天吃下两茶匙的盐。这个摄取量比每日建议的2000毫克(约1茶匙盐)整整高出一倍。

  另外,几乎所有国人的钠摄取量都不达标。去年有95%的国人超标,高于2019年的88%。

  钠主要来源自熟食中的盐、酱汁与调味料,占60%。加工食品如快熟面、加工肉类则占来源的15%。其余则包括炸物、甜品、面包等等。

逾半数国人热量摄入超标

  另外,调查也指出国人每日平均热量摄入从2019年的2360千卡(kcal)升至去年的2460千卡。在计入体能活动消耗后,超过半数(57%)的国人热量摄入超标。

  像白米和白面包这类精制碳水化合物的摄取量也从2019年的154克增至166克。由于这类食物纤维和其他营养素较为不足,同样值得注意。

  此外,国人每日总脂肪摄入量也从2019年的94克增至103克,饱和脂肪占总脂肪摄入的35%,已超过不超过30%的推荐上限。

各年龄层的卡路里摄入量(千卡)

  年龄层 2019年 2025年

  18至29岁 2576千卡 2655千卡

  30至49岁 2434千卡 2576千卡

  50至69岁 2159千卡 2230千卡

  (数据来源:2019年和2025年全国营养调)

钠从哪里来?

  汤类食物(鱼汤、面汤、叻沙等)

  加工食品(快熟面、香肠等)

  酱汁食物(米暹、三捞河粉等)

  翻炒食物(菜头粿、炒饭等)

  

七成国人每日外食

常见熟食热量钠含量增约10%

  重油重咸食物如麻辣香锅不应每天当正餐。

  调查也显示,国人外食(包含外卖)频率的增加是导致卡路里、钠等摄取量超标的主要推手。去年,每天至少外食一次的本地居民比例达到七成,高于2019年的六成。

  保健促进局对182种常见熟食的分析也发现,去年常见外食菜肴的平均热量和钠含量均比2023年增加了约10%,而且许多常见菜色的增幅还超过10%。例如一份海南鸡饭的热量从557千卡升至646千卡、炒粿条从748千卡升至989千卡。

  当局推测,这可能是因为原料成本上涨,有业者因此在料理中增加了成本较低的精制碳水化合物及油脂酱汁所致。

重油重咸美食只可偶尔为之

  此外,新兴的热门美食如麻辣香锅和番茄火锅也含高热量与极高钠含量,前者一份可含1165千卡热量与3100毫克的钠,后者一份可含1152千卡热量与4900毫克的钠。

  当局提醒,重油重咸的美食应被视为“偶尔为之的犒赏”,而不应每天当成正餐。公众应学会平衡整体膳食,如午餐吃了重口的美食,晚餐就应选择清淡、低钠的汤品或蒸煮食物。

50岁以上群体

蛋白质摄取不足

  年长者蛋白质摄取不足。

  在蛋白质摄取方面,有近八成(79%)达标,每日平均摄取量从2019年的88克增至去年的98克。

  不过50岁至69岁的群体,有超过半数(55%)未达到推荐的蛋白质摄取标准。

  根据官方建议,蛋白质建议摄取量跟体重有关。50岁以下成人为每公斤体重应摄取0.8克蛋白质,50岁以上成年人则为1.2克。

  当局建议,年长国人可多选择豆浆等富含蛋白质的饮品,并留意印有“较健康选择标志”的产品。在购买包装食品时,也可选择标有“较高蛋白质”的低脂牛奶或低糖酸奶饮料。

九成国人体能活动量足够

  全国人口健康调查显示,将近九成国人体能活动足够。

  2025年的全国人口健康调查结果也在今天公布。自“健康SG”计划推行以来,慢性疾病与癌症筛检参与率均有所提升。

  此外,国人体能活动量足够(即每周进行至少150分钟中等强度运动)的比率,从2024年84.7%上升至去年的87.3%,恢复至疫情前水平。

多管齐下守护国人健康

  当局多方面努力助国人改善健康。

  为改善国人健康,当局表示从多方面下手,包括鼓励人们通过健康SG预防疾病、 鼓励人们更健康饮食、保持活跃生活等等。

  在改善饮食方面,当局计划在2028年前将营养等级(Nutri-Grade)标签和广告禁令扩大至包装盐、酱汁、调味料、即食面及食用油。当局也会继续推动其他相关计划,鼓励消费者在外用餐时主动要求“少盐少酱”,让“少盐少酱”逐步成为常态。

  另外,目前每月有近90万名活跃用户使用Healthy 365应用,来追踪各项健康生活数据与指标。

  当局也在今年7月底开始在HealthHub应用试行“保健护理计划人工智能”(Health Plan AI)测试版功能,为健康SG参与者量身定制运动计划。

Education: Building Confidence in Many Paths to Success (Closing Speech by Second Minister for Education David Neo at 2026 Institute of Policy Studies (IPS) Forum) -- 2026-09-29

A Singapore Government Agency WebsiteHow to identify 

Closing Speech by Second Minister for Education David Neo at 2026 Institute of Policy Studies (IPS) Forum, Building Confidence in Many Paths to Success

Published on: 29 Sep 2026

NewsSpeeches

1. Good afternoon.

2. Before I begin, let me say that Minister Desmond Lee was looking forward to being here today. Unfortunately, he is unwell and unable to join us. He sends his apologies and has asked me to deliver the remarks on his behalf.

3. To start, let me thank IPS for organising this forum, and to all of you for contributing actively to today's discussions.

4. We have heard many thoughtful views today. They add to what many other Singaporeans have shared with us during our Education Conversations.

5. This afternoon, I would like to share what we have learnt and the difficult questions we must consider before moving on to the next phase of the Conversations.

The Tension at the Heart of Parenting Today

6. Our children are growing up in a rapidly changing world.

  1. Technology is transforming how we live, how we learn and how we work.
  2. Domain knowledge will remain important, but our children will also need qualities that are deeply human: empathy, judgement, ethical decision-making, curiosity and the ability to work with others.

7. Parents understand this. We want our children to do well academically, but we also want them to develop character, discover their interests, build meaningful relationships and find purpose in what they do.

8. The IPS study shows that parents want their children to have a broader, more holistic education.

9. Yet, parental stress has increased, and families are investing more time and money in tuition and enrichment.

10. This tension surfaces in the choices families make every day.

  1. Their children are doing reasonably well in school. But could another tuition class help them gain a few more marks? After a long day, do we fit in another hour of revision, or do we say, "Enough for today. Let's go for a walk, have dinner and let's have a conversation"?
  2. Or perhaps our children love playing football with friends, but are not winning trophies or building a portfolio. Do we let them continue playing for the joy, friendship and growth it brings? Or do we look for another activity that might be more useful for DSA?

11. There are no simple answers. And the IPS findings highlight these tensions.

  1. Nearly nine in ten parents agreed that children in Singapore spend far too much time on tuition and enrichment.
  2. But seven in ten said that, if they had the resources, they would spend more on these activities for their own children.
  3. Around half felt pressure because other parents were doing so.

12. Some spoke about education feeling like an arms race. Most parents are not asking for this race. They are saying that they are not sure if their children can afford to sit it out.

13. This distinction is crucial. Parents know that academic success can open doors, but aptitude, character and values enable us to thrive in life. Yet though most want to step back from this race, many still take part, hoping to give our children the best chance of getting through those doors. The result is an unhealthy "arms race" that few want to join, but many feel compelled to be part of.

14. This has real costs. When academic achievement becomes the safest currency, other valuable aspects of holistic development can be crowded out – even though parents recognise their importance.

  1. Our children may have less time to explore their interests and nurture the curiosity, creativity and resilience that are equally important for success in life.
  2. In some cases, it can also place children under excessive stress, dulling their love for learning, and affecting their overall development and well-being.

The Real Driver: Perceived Stakes of Educational Choices

15. So why do parents feel this tension?

16. Across our conversations, we have heard a familiar chain of assumptions.

  1. Doing well in an examination helps a child enter a so-called "good" school.
  2. A "good" school is believed to provide a better environment and better opportunities and improve the child's chances of entering a "good" university course.
  3. A "good" course is then seen as the route to a "good" job, "good" pay and, ultimately, a "good" life.

17. These narratives are deeply rooted in many parts of society. Our visits to education systems across Europe and Asia show that they exist elsewhere, to varying degrees. If parents believe that every link in this chain could make or break their child's future, then every educational choice will feel momentous.

18. But these narratives rest on a narrow definition of what "good" is –academic achievement in particular subjects, or employment in particular fields. They overlook other outcomes we also want for our children: strength of character, a sense of purpose and the confidence to contribute when they grow into adults.

19. MOE has long worked to broaden this definition – by creating more diverse and porous pathways, and by helping students navigate them according to their strengths, interests and aspirations. These changes reduce the chance that one result, one school or one decision made at a young age will determine a child's future.

20. These narratives extend well beyond education. We cannot end the education "arms race" through changes to the education system alone. We must also consider how our society and economy can help parents strike a healthier balance for their children, without fearing that they will be disadvantaged.

21. We are seeing encouraging signs of change beyond schools.

  1. More employers are looking beyond academic credentials, placing greater emphasis on applicants' skills, experiences and dispositions.
  2. We are also seeing a gradual shift in mindsets, as people increasingly recognise that, in a world of constant change, no school or degree can equip us with everything we will need for our working life. So, we must keep learning throughout life. The growth of the SkillsFuture movement over the past 11 years reflects this shift towards continual upskilling and lifelong learning.

22. We still have some way to go. As a society, we must define success less by what is achieved in the first 15 years of schooling, and more by how people contribute to their workplaces, communities and our nation over a lifetime.

An Education System that Builds Confidence for Families

23. So, what does this mean for our education system?

24. Within education, we want to build a system that gives parents confidence to place less emphasis on achievement and more on holistic development — knowing that this will prepare their children for long-term success.

25. Let me be clear: We are not against striving. Nor are we talking about dropping standards. Singapore has progressed because generations of Singaporeans worked hard, persevered and aspired to do better. Our children should learn to set goals, meet challenges and recover from setbacks.

26. But healthy striving is different from endlessly chasing the last mark. Healthy striving helps a child grow. Chasing marginal gains from a young age can make every decision seem disproportionately consequential, leaving less room to build strong foundations, curiosity and a lasting love of learning.

27. Therefore, our aim is not to remove all competition, stress or disappointment from education. That would not be realistic, nor would it prepare our children well for life. Other countries that have reduced or removed major examinations have found that pressures do not simply disappear, but instead re-emerge in other ways.

28. Our aim is to ensure that competition does not become the all-consuming thing that crowds out the pursuit of qualities that our children will need to flourish.

29. This direction is not new.

  1. In 2021, we replaced PSLE T-scores with Achievement Level bands, reducing the pressure to chase every mark.
  2. In 2024, we replaced streaming with Full Subject-Based Banding, allowing students to learn each subject at a pace suited to their needs and move more flexibly between bands.
  3. In 2025, we removed mid-year examinations at all levels, freeing time for learning, exploration and growth.
  4. We have also expanded aptitude-based admissions and strengthened applied and work-study pathways to better serve students' different strengths, needs and aspirations.

30. But the IPS findings and Education Conversations tell us that we need to go further.

  1. Over the past year, Singaporeans from all walks of life have shared their aspirations through the Education Conversations.
  2. Views differed on the solutions, but parents shared one aspiration: to raise well-rounded children without having to optimise every decision for the next academic milestone.

31. How, then, can our education system assure parents that holistic development need not come at the expense of success — especially where the stakes feel highest?

32. The next phase of the Education Conversations will focus on the parts of the system that most fuel the "arms race", where thoughtful changes could give children more room to grow.

  1. In particular, we will examine the transition from primary to secondary school, where pressure on young students is often most acute.

33. Three topics surfaced most repeatedly: the PSLE, DSA, and the deeper question that is underlying both — how to strengthen schools across the system. Let me take each in turn.

PSLE

34. For many parents, the pressure is felt most sharply at the PSLE. It arose in almost every conversation.

35. The PSLE serves three distinct purposes:

  1. Assessing a child's understanding of the primary school curriculum;
  2. Second, providing a basis for secondary school placements; and
  3. Third, matching our students to the appropriate subject levels in secondary school.

36. Not all contribute equally to the pressure.

  1. The IPS study found that more than eight in ten parents see the PSLE as an important milestone that teaches children to set goals and to work hard. A similar proportion valued having a national examination as a fair assessment and preparation for secondary school.
  2. Much of the pressure comes from using PSLE results for secondary school posting. When scores determine access to preferred schools, parents understandably feel they cannot afford to ease off.

37. We heard many suggestions to reduce the stakes associated with PSLE.

  1. Some proposed removing, postponing, or even making PSLE optional.
  2. Others suggested making the scoring bands broader at the top, so that students do not have to chase every mark, but narrower at the bottom, to better reflect the performance of our academically weaker students and to recognise their efforts to improve.
  3. Some proposed changing the way students are posted to secondary schools.
  4. Many felt that the deeper answer lies in strengthening more schools, so that families do not feel the need to get their children into a handful of perceived "good" schools.

38. Each idea addresses a concern. But each may also create new pressures.

  1. For example, if secondary school posting were no longer based mainly on PSLE results, what should replace it – balloting, proximity, or a through-train model?
    1. More balloting could increase uncertainty and anxiety. This could also occur if we blunt PSLE scoring further, as more students will have the same score.
    2. Proximity could worsen social mixing by clustering students according to where they live.
    3. A through-train model could shift competition to Primary 1 admission and reduce students' ability to choose a secondary school that suits the interests and needs they develop later.
    4. It would also raise a difficult question: which primary schools should be linked to the more sought-after secondary schools?

39. These trade-offs are not reasons to avoid change. But they are reasons to be clear-eyed about our aims and about both the intended and unintended effects. For every proposal, we should ask:

  1. Will it give our children more room to learn, to explore and to grow?
  2. Will it preserve fairness and maintain high standards?
  3. Will it help families focus more on a school's fit for their child?
  4. Where might it displace competition and stress?

DSA

40. The second major topic is DSA.

41. DSA was introduced to recognise students' talents, aptitude and potential, beyond examination results.

  1. This remains valuable.
  2. Children have different strengths — academic subjects, sports, music, art, leadership as well as other areas.

42. But parents and students also told us about a difficult tension.

  1. For some families, DSA now feels like a second front in the "arms race", adding to the anxiety.
  2. Children may prepare for the PSLE while also building a DSA portfolio to secure a place in a preferred school.
  3. A genuine interest can then become an admissions strategy. Coaching starts earlier, competitions carry higher stakes, and some students eventually burn out and ask to leave the programme.
  4. Some parents worry that better-resourced families can afford specialised training that others cannot.
  5. Others have benefitted from a pathway that recognises talents and strengths developed through school, beyond academic grades.

43. How, then, do we preserve DSA as a pathway that broadens our definition of merit while reducing competitive pressure? As with the PSLE, we heard a very good range of ideas:

  1. Some felt DSA should be scaled back or even abolished.
  2. Others argued that it should be expanded so we can assess students more holistically.
  3. Some suggested distributing DSA places or talent areas more widely across schools.
  4. Others suggested that DSA should focus more on recognising aptitude and interest, rather than skills that can be intensively coached.

44. The views differ, but they point to the same question: How can DSA recognise different strengths credibly, without turning every interest into an admissions strategy?

  1. If we narrow DSA too sharply, we may send the message that examination performance is once again the only form of merit that counts.
  2. If we broaden it without care, we may create more areas in which families feel compelled to invest just to compete.
  3. If we place greater emphasis on aptitude, the assessment could be more subjective, and therefore seen as unfair.
  4. If we remove it entirely, the pressures may simply return to PSLE, and send the wrong signal that only academics matter.

45. So the goal is not more or less DSA. It is to reconnect talent recognition with genuine development.

  1. A child should be able to enjoy a sport without being asked whether it will produce medals or whether it will contribute to their DSA portfolio.
  2. A child should be able to learn music without every lesson building towards a certificate.
  3. Where a child shows deep aptitude and commitment, DSA should help us recognise and develop that talent.

Strengthen Our Schools

46. The third topic is how families view our schools. We must assure parents that strong teaching, rich development opportunities and credible routes to success exist across the system — not just in a few schools.

47. Every school has committed educators, a distinctive culture and areas of strength. Schools serving more disadvantaged students also receive additional manpower and funding.

48. Yet parents still see some schools as "good" schools, and others less so. We want parents to trust that schools across the system can help their children thrive, and to choose more by fit than reputation. We therefore need to ask:

  1. How can schools work more closely with one another and with community partners, so that programmes, networks, internships and alumni connections benefit more students?
  2. How can we make the strengths of schools across our system better known?
  3. How do we help parents look beyond prestige and popularity to ask whether a school is the right fit for their child?

49. If families trust that schools across the system can help their child thrive, then any single posting outcome will carry less weight. Parents will still have preferences, and schools will differ in history, culture and programmes. But choosing one school over another need not feel like choosing a destiny.

Conclusion

50. Let me return to the parents I mentioned at the start: deciding between another hour of revision or a walk with their child; wondering whether football can remain something their child truly enjoys.

51. These conversations show that parents already value holistic development. Our task is to give them greater confidence to act on those values, by addressing features of our education system that can make each choice feel high-stakes.

52. We approach these issues from a position of strength. Our education system has served generations of Singaporeans well and built strong foundations for our children. But as pressures rise and as the world changes, we must build on those strengths, so families can give children room to grow without fearing that our children might lose out.

53. Education changes alone cannot lower the stakes entirely. Lasting change also depends on employers, institutions and society – all of us – recognising multiple pathways, valuing different strengths and experiences, and respecting every worker and every contribution.

54. I therefore invite Singaporeans to share your experiences and ideas in the next phase of the Education Conversations, especially on where the stakes feel highest. There are no easy answers. That is why we are consulting widely, rather than rushing to a single solution.

55. Let us work together to preserve the strengths built by earlier generations, while giving every child the space to discover their strengths and to fulfil their potential — in school and beyond.

56. Last but not least, I would like to thank every single one of you in this room for contributing your ideas, your suggestions, and having the welfare of our children in the middle of all of this. Thank you very much.
