How Much More Will the New US “Real Food” Pyramid Cost a Family of Four?

 How Much More Will the New US “Real Food” Pyramid Cost a Family of Four?


The new U.S. “real food” pyramid emphasizes more protein, full‑fat dairy, healthy fats, fruits, vegetables, and whole grains, while sharply cutting ultra‑processed and sugary foods. From a cost viewpoint, shifting an average family of four from the old grain‑heavy pyramid to this higher‑protein, minimally processed pattern is likely to increase their monthly grocery spending by roughly 10–25%, depending on how they shop and what substitutions they make.

What the new pyramid emphasizes

  • The new pyramid calls for “high‑quality, nutrient‑dense protein foods” at every meal (eggs, poultry, seafood, red meat, beans, nuts, seeds) and more full‑fat dairy, alongside fruits, vegetables, healthy fats and whole grains.

  • It also urges people to replace highly processed foods and refined carbohydrates with “real food” and to eat about 1.2–1.6 grams of protein per kilogram of body weight daily, up from the prior 0.8 g/kg guideline.

How it differs from the old pyramid

  • The 1990s USDA pyramid put refined and whole grains as the large base, with 6–11 servings per day, and treated fats and oils as something to “use sparingly,” keeping protein portions modest.

  • The new “real food” pyramid inverts that logic: vegetables, fruits, proteins, dairy and healthy fats form the foundation, while refined grains and sugary products shrink to a small top tier.

Cost drivers of the new approach

  • Protein foods (meat, fish, eggs, nuts) and full‑fat dairy generally cost more per calorie than refined grains, added sugars and many ultra‑processed items, so raising protein targets and replacing cheap processed staples tends to raise the food bill.

  • At the same time, shifting from restaurant/fast‑food and heavily processed snacks to home‑cooked meals built on basic ingredients can offset some of that increase, because prepared ultra‑processed items carry a convenience markup.

Estimated extra monthly cost for a family of four

  • For an average family of four moving from a grain‑heavy, processed‑food pattern closer to the old pyramid toward the new higher‑protein, whole‑food pattern, a reasonable rough estimate is an extra 80–250 USD per month in groceries, or about 1,000–3,000 USD more per year.

  • The lower end of that range assumes strategic choices such as more beans, lentils, eggs and frozen vegetables, while the higher end reflects frequent use of fresh meat, seafood, nuts and premium “clean label” products.

Ways to control costs under the new pyramid

  • Families can keep costs closer to the low end of the range by emphasizing budget‑friendly proteins (beans, lentils, eggs, canned fish, chicken thighs), buying whole foods in bulk, and relying on frozen fruits and vegetables.

  • Planning simple home‑cooked meals, limiting snacks and sugary drinks, and reserving red meat and specialty items for fewer meals can preserve the health benefits of the new pyramid while keeping the overall budget more manageable.

瞬時信息的雙面刃:從印刷術到全球演算法的社會思辨

 

瞬時信息的雙面刃:從印刷術到全球演算法的社會思辨

印刷術如何徹底改變了大宋,並為蘇軾等人物帶來了意想不到的後果。今天,我們正處於一個更為激進的轉折點。當信息(無論是文字、圖片還是短影音)能瞬間傳遞給全球數十億人時,社會學意義上的變革不僅是速度的加快,更是本質的翻轉。

1. 模糊空間的武器化

文字包含「巨大的模糊空間」,既能冤枉無辜,也能讓高手隱晦抨擊。在 AI 生成內容與短影音時代,這種模糊性呈爆炸式增長。

  • 非預期後果: 「語境崩塌」。一段十秒鐘的言論被剝離了前後文,瞬間傳播給數十億人。在缺乏時間緩衝或地方背景的情況下,這種「模糊空間」不再是智者的護身符,而是平庸者的陷阱。真相還在穿鞋,網路審判已經在全球範圍內完成。

2. 超速傳播帶來的「惡運」

在宋代,蘇軾的詩傳回京城的速度快過了他解釋意圖的速度,導致他被貶海南。如今,信息的傳遞速度不僅超過了「人際交往」,更超過了人類認知的處理極限。

  • 社會變革: 我們現在處於一種對安寧的「永久流放」狀態。任何地方發生的危機,都會同時出現在所有人的螢幕上。這造就了一個高度焦慮的社會,政府與公眾往往被迫根據「情緒」和「病毒式趨勢」而非深思熟慮的事實做出反應。

3. 全球尺度下的「虛構故事」整合力

哈拉瑞認為,人類合作建立在「共享虛構」之上,如金錢、宗教或國家。印刷術讓這些故事得以低成本分發,將陌生人組織成強大的集體。

  • 全球之利: 我們現在能在幾小時內組織全球性的氣候變遷或人權運動。

  • 全球之弊: 我們正目睹「現實的碎片化」。由於我們可以向特定的「同溫層」發送專屬的虛構故事,我們不再擁有一個共同的大敘事。數十億人被組織成數千個衝突的「虛擬部落」,每個人都相信自己的真相版本,這使得大規模的國家或全球共識變得近乎不可能。

The Double-Edged Sword of Instantaneous Information: From Printing Presses to Global Algorithms

 

The Double-Edged Sword of Instantaneous Information: From Printing Presses to Global Algorithms

How the printing press revolutionized the Song Dynasty, creating unintended consequences for figures like the poet Su Shi. Today, we stand at a far more radical precipice. When information—whether text, image, or short video—is transmitted instantaneously to billions, the sociological shifts are not just faster; they are transformative.

1. The Weaponization of Ambiguity

One notes that text contains a "vast space of ambiguity" that can either frame the innocent or allow masters like Su Shi to hide critiques in plain sight. In the age of AI-generated content and short videos, this ambiguity has exploded.

  • The Unintended Consequence: "Context collapse." A ten-second clip of a person’s speech can be stripped of its nuances and broadcast to billions. Without the "buffer" of time or local context, the "space for ambiguity" is no longer a shield for the wise; it is a trap for the unwary. Public shaming becomes a global, instantaneous event before the "truth" can even lace its boots.

2. The Curse of Hyper-Speed

In the Song Dynasty, Su Shi’s poem reached the capital faster than he could personally explain his intent, leading to his exile to Hainan. Today, the speed of information exceeds not just "interpersonal communication" but human cognitive processing itself.

  • The Societal Shift: We now live in a state of "permanent exile" from peace. When a crisis happens anywhere, it happens everywhere simultaneously on our screens. This creates a high-anxiety society where the government and the public must react to "vibes" and viral trends rather than deliberated facts.

3. The Power of "Shared Fictions" at Scale

Yuval Noah Harari argues that human cooperation is built on "shared fictions"—stories like money, religion, or nations. The printing press allowed these stories to be distributed cheaply, organizing strangers into powerful collectives.

  • The Global Good: We can now organize global movements for climate change or human rights in hours.

  • The Global Bad: We are seeing the "fragmentation of reality." Because we can now transmit specialized "fictions" to specific echo chambers, we no longer share one big story. Billions of people are organized into thousands of conflicting "virtual tribes," each believing in their own version of the truth, making large-scale national or global consensus nearly impossible.




Understanding Sullivan’s Law: The "Invisible Drift" of Institutions

 

Understanding Sullivan’s Law: The "Invisible Drift" of Institutions

深入解析「薩利文定律」:機構背後的「隱形左傾」

In recent political discourse, former British Prime Minister Liz Truss has frequently invoked Sullivan’s Law to explain why conservative governments often struggle to implement their agendas. This sociological observation provides a framework for understanding how powerful institutions—from central banks to global NGOs—seem to drift toward "progressive" or "left-wing" ideologies over time, regardless of who is in power.

在近期的政治討論中,前英國首相**卓慧思(Liz Truss)經常引用「薩利文定律」(Sullivan's Law)**來解釋為什麼保守派政府在推行政策時往往阻礙重重。這一社會學觀察提供了一個框架,讓我們理解為什麼從中央銀行到全球非政府組織(NGO)等強大機構,無論誰在執政,似乎都會隨著時間推移而傾向於「進步主義」或「左翼」意識形態。


What is Sullivan’s Law? | 什麼是薩利文定律?

The law was coined by John O’Sullivan, a British conservative commentator and former speechwriter for Margaret Thatcher. The principle states:

"All organizations that are not actually right-wing will over time become left-wing."

這條定律是由英國保守派評論家、曾任戴卓爾夫人撰稿人的**約翰·奧薩利文(John O’Sullivan)**所提出。其核心原則是:

「任何不具備明確右翼傾向的組織,隨著時間推移,最終都會變成左翼。」

Why Does This Happen? | 為什麼會發生這種現象?

According to O'Sullivan and supporters of this theory like Liz Truss, several factors drive this institutional drift:

  1. Selection Bias in Recruitment: People drawn to roles in the public sector, academia, and NGOs often hold more communal or progressive values. Over decades, this creates a "consensus swarm" or "The Blob."

  2. The Path of Least Resistance: Left-wing activists are often more focused on capturing institutional culture. For a non-aligned administrator, adopting "progressive" policies (like Net Zero or EDI initiatives) is often seen as the safer, more socially acceptable path to avoid conflict.

  3. Institutional Capture: Once a critical mass of staff holds a specific worldview, the institution begins to define "neutrality" based on that worldview. Anything outside of it is labeled "extreme."

根據奧薩利文及卓慧思等支持者的說法,這種機構偏移由以下幾個因素驅動:

  1. 招聘中的選擇性偏差: 傾向於進入公共部門、學術界和非政府組織工作的人,通常持有較強的集體主義或進步主義價值觀。幾十年下來,這形成了一種「共識蜂群」或被稱為「大堆頭(The Blob)」的現象。

  2. 阻力最小的路徑: 左翼活動家通常更致力於佔領機構文化。對於一個中立的管理者來說,採納「進步主義」政策(如淨零排放或多元平等共融 EDI 倡議)通常被視為避免衝突、更安全且社會接受度更高的選擇。

  3. 機構俘虜: 一旦職員中持有特定世界觀的人數達到臨界點,該機構就會開始根據該世界觀來定義「中立」。任何在此框架之外的觀點都會被貼上「極端」的標籤。


Liz Truss and the "British Deep State" | 卓慧思與「英國深層政府」

Liz Truss argues that during her brief 2022 premiership, she wasn't just fighting political opponents, but an entrenched technocracy governed by Sullivan’s Law. She points to several key examples:

  • The Bank of England & HM Treasury: She believes these institutions are wedded to Keynesian economics (high spending/borrowing) and were hostile to her supply-side tax cuts.

  • Net Zero & Climate Orthodoxy: Organizations like the OBR (Office for Budget Responsibility) prioritize environmental targets over raw economic growth, treating Net Zero as an unquestionable moral imperative rather than a policy choice.

  • Identity Politics: The spread of "woke" ideology within the civil service, where institutional energy is spent on identity-based social engineering rather than administrative efficiency.

卓慧思主張,在她 2022 年短暫的首相任期內,她不僅是在與政治對手鬥爭,更是在與受薩利文定律支配的根深蒂固的技術官僚體系作戰。她舉出了幾個關鍵例子:

  • 英格蘭銀行與財政部: 她認為這些機構沉迷於凱恩斯主義經濟學(高支出/高借貸),並對她的供給側減稅政策抱持敵意。

  • 淨零排放與氣候正統: 像**預算責任辦公室(OBR)**這樣的組織,將環境目標置於純粹的經濟增長之上,將「淨零」視為不容置疑的道德命令,而非一種政策選擇。

  • 身分政治: 「覺醒(Woke)」意識形態在公務員體系中的傳播,導致機構精力被耗費在基於身分的社會工程上,而非行政效率。


The Counter-Strategy | 應對策略

Truss and her allies argue that to fix the economy, a government cannot simply win an election; it must dismantle the "House of Blair"—the legal and institutional framework left behind by the left. They suggest moving toward an American-style system of political appointments, ensuring that the people running the "Deep State" actually share the democratic mandate of the elected government.

卓慧思及其盟友認為,要挽救經濟,政府不能僅僅贏得選舉,還必須拆解「布萊爾之屋」——即左翼留下的法律和機構框架。他們建議轉向美國式的**「政治任命制」**,確保管理「深層政府」的人員真正認同民選政府的民主授權。


The Marginal Cost of a Journey: Why Free Senior Travel is "Free" for the Taxpayer

The Marginal Cost of a Journey: Why Free Senior Travel is "Free" for the Taxpayer

Recent discussions surrounding the UK bus pass rules for 2026—as highlighted by the UK Seniors Hub [00:17]— https://youtu.be/DrgIj_PfppM?si=br1IpR_8v6qbDmpS often focus on the "financial strain" local councils face. Headlines warn of eligibility shifts linked to the rising state pension age [02:37] and stricter renewals to "prevent misuse" [05:39]. However, from the perspective of throughput accounting, the argument that providing free travel to seniors creates a significant "added cost" for Transport for London (TfL) or other regional networks is largely a myth.

Here is why the real cost of letting a senior board a bus or train is effectively zero, and why the "budget crisis" lies in maintenance, not passengers.

1. The Reality of Fixed Costs

In transport logistics, the vast majority of expenses are fixed. Whether a London bus carries 5 people or 50, the costs remain identical:

  • The Driver: The salary is paid regardless of passenger count.

  • The Schedule: The bus runs on a fixed route at a fixed time.

  • Fuel/Power: While weight slightly affects fuel consumption, the difference between an empty bus and one with five extra seniors is statistically negligible.

  • Infrastructure: The tracks, stations, and signaling systems cost the same to maintain whether the trains are full or empty.

In throughput accounting terms, "Operating Expense" is relatively flat. Unless TfL plans to drastically reduce service frequency, decommission a large portion of the fleet, and lay off drivers, the system's "cost" is already sunk.

2. Zero Marginal Cost

The "marginal cost" is the cost of producing one more unit—in this case, one more passenger journey. Because the bus is already running and the driver is already driving, the cost of one more person boarding is zero.

Conversely, if a senior decides not to travel because they cannot afford the fare, there is zero reduction in cost for the transport authority. The bus still drives the route, consumes the fuel, and pays the driver. Removing the "free" element doesn't save the system money; it simply results in empty seats and socially isolated seniors [01:26].

3. Misplaced Blame: Maintenance vs. Passengers

The narrative that "more people living longer" [07:31] is the primary driver of financial strain ignores the true "black hole" in transport budgets: Inefficient Preventive Maintenance.

When a system suffers from poor maintenance protocols, it drives up total fixed costs through:

  • Emergency Repairs: Which are significantly more expensive than scheduled upkeep.

  • Asset Degradation: Shortening the lifespan of expensive buses and trains, requiring premature capital expenditure for new fleets.

  • Service Reliability: Breakdowns lead to fines, lost productivity, and the need for "standby" equipment.

If TfL or local councils are facing a budget deficit, the culprit is likely the management of these high-level fixed costs and technical inefficiencies, not the senior citizen using a seat that was going to that destination anyway.

4. The Social Throughput

From a holistic viewpoint, "throughput" isn't just about fare revenue; it’s about the movement of people to keep the economy and society functioning. As noted in the video, for many, the bus pass is a "lifeline" to reach GPs, chemists, and shops [01:18].

When seniors travel, they participate in the economy. If we restrict their travel based on the false premise of "added transport costs," we create real costs elsewhere—such as increased NHS spending due to isolation-related health issues or decreased local commerce.

Conclusion

The "urgent rule changes" and "cost control" measures being discussed for 2026 [05:15] are often based on traditional cost-accounting that treats every passenger as a liability. Throughput accounting reveals the truth: the seats are already paid for. Providing free travel to seniors is a high-impact social benefit with near-zero marginal cost. The real financial challenge for our transport networks isn't the person with the pass; it's the efficiency of the machine itself.

放慢瓶頸的策略價值

 

放慢瓶頸的策略價值

為何降低吞吐量反而能在商業與人生中創造更大價值

摘要

限制理論(TOC)普遍主張透過加速瓶頸來提升系統吞吐量。然而,當瓶頸的角色並非收入產生,而是成本調節、行為引導、價值訊號或能力培養時,這一原則反而會造成傷害。本文透過商業與人生案例說明,刻意放慢瓶頸往往是更優的整體決策,因為它能使系統行為與真正目標一致,進而提升長期績效。


一、「充分利用瓶頸」背後的隱含假設

加速瓶頸的前提是:

瓶頸流量增加,系統就更接近目標。

當此假設不成立時,加速瓶頸就成了局部最佳化的陷阱。在多數服務型與人本系統中,瓶頸的真正功能是調節與引導,而非生產。


二、瓶頸作為經濟調節器的商業案例

2.1 固定收入系統:速度帶來的是成本

案例:自助餐

  • 收入固定

  • 高價食材消耗與速度正相關

  • 放慢瓶頸 → 成本下降 → 利潤上升

瓶頸若被加速,反而傷害系統。


2.2 銷售能力:保護瓶頸免於低價值需求

  • 銷售人員是瓶頸

  • 過多線索降低成交率

  • 資格篩選刻意放慢流程

結果是:更少的流量,更多的成交價值


2.3 客服系統:用延遲塑造行為

  • 快速支援鼓勵低價值使用

  • 放慢免費支援促使升級或自助

瓶頸變成行為槓桿,而非服務缺陷。


2.4 稀缺性:維持價格與品牌的瓶頸

  • 閒置產能在營運上是浪費

  • 在策略上是價值來源

放慢供給,反而保護整體吞吐量。


三、人生系統中的能力型瓶頸

3.1 教養:放慢幫助,才能加速成長

  • 快速介入降低學習

  • 延遲介入建立能力

短期慢,長期快。


3.2 生產力:能量才是真正瓶頸

  • 過度輸出消耗能量

  • 刻意放慢避免崩潰

保護瓶頸,提升終身產出。


3.3 關係:情緒處理限制了速度

  • 推進太快造成抗拒

  • 放慢溝通建立信任

吞吐量是關係品質,而非進度。


四、為何放慢瓶頸能改善整體結果

放慢瓶頸能:

  1. 降低破壞價值的流量

  2. 將需求導向高價值

  3. 保護稀缺資源

  4. 引導行為而非被行為牽著走

  5. 累積長期能力與信任


五、TOC 的成熟詮釋:利用 vs. 保護

並非所有瓶頸都該被「利用」。

有些瓶頸必須:

  • 被保護

  • 被調節

  • 被刻意限速

關鍵判斷問題是:

增加瓶頸流量,是在放大價值,還是在稀釋價值?


六、結論

放慢瓶頸不是違反 TOC,而是對 TOC 的深度理解與成熟運用。在這些系統中,速度不是槓桿,控制才是

最終結論是:

系統存在的目的,不是更快,
而是更接近它真正的目標。

The Strategic Value of Slowing the Constraint

 

The Strategic Value of Slowing the Constraint

Why Less Throughput Can Create More Value in Business and Life

Abstract

Conventional applications of the Theory of Constraints (TOC) emphasize accelerating the system constraint to increase throughput. While valid in many operational contexts, this principle becomes harmful when the constraint governs cost, behavior, perception, or long-term capability rather than revenue flow. This paper argues that in such systems, deliberately slowing the constraint produces superior global outcomes. Through examples from business and everyday life, we demonstrate that reduced local throughput can improve profitability, sustainability, and effectiveness by aligning system behavior with its true goal.


1. The Hidden Assumption Behind “Exploit the Constraint”

The directive to exploit the constraint rests on a silent assumption:

More flow through the constraint moves the system closer to its goal.

When this assumption holds, speeding up the constraint is correct. When it does not, acceleration becomes a form of local optimization that damages the system.

In many modern systems—especially service, knowledge, and human systems—the constraint’s primary role is not production, but regulation.


2. Constraint as an Economic Regulator in Business

2.1 Fixed-Revenue Systems: When Speed Increases Cost

Example: Buffet restaurants
Revenue per customer is fixed, while costs rise with consumption of premium items.

  • Faster carving → more expensive consumption

  • Slower carving → substitution toward cheaper food

  • Result: higher profit with lower throughput

Here, slowing the constraint reduces cost without reducing revenue, improving global performance.


2.2 Sales Capacity: Protecting the Constraint from Low-Value Demand

Example: Enterprise sales teams

  • Salespeople are the constraint

  • Flooding them with unqualified leads increases activity but lowers close rates

  • Deliberate qualification steps slow the flow

Slowing the constraint:

  • Preserves sales energy

  • Improves win rates

  • Increases revenue per sales hour

Throughput is reduced; economic throughput increases.


2.3 Customer Support: Using Delay to Shape Behavior

Example: SaaS freemium models

  • Instant support for all users overwhelms teams

  • Fast support encourages heavy usage by non-paying users

By slowing support for free tiers:

  • Users self-solve or upgrade

  • Support capacity shifts to profitable customers

  • Overall system profitability improves

The constraint becomes a behavior-shaping mechanism, not a service failure.


2.4 Scarcity as a Constraint: Preserving Pricing Power

Example: Luxury goods and premium services

  • Operationally, unused capacity appears as waste

  • Strategically, scarcity increases perceived value

Slowing output:

  • Sustains exclusivity

  • Maintains price integrity

  • Protects long-term brand throughput

Maximizing unit flow would destroy the system’s economic engine.


3. Constraint as a Capability Builder in Life Systems

3.1 Parenting: Slowing Help to Accelerate Growth

  • Parent’s time and attention are the constraint

  • Immediate intervention solves problems quickly

  • But it weakens learning and independence

By slowing intervention:

  • Children struggle productively

  • Capability increases

  • Long-term throughput of competence improves

The short-term system slows; the long-term system accelerates.


3.2 Personal Productivity: Energy as the True Constraint

  • Human energy is finite and regenerative

  • Maximizing daily output depletes the constraint

By deliberately slowing:

  • Rest is protected

  • Burnout is avoided

  • Lifetime productivity increases

The constraint must be preserved, not exploited.


3.3 Relationships: Emotional Processing as a Constraint

  • Emotional readiness limits progress

  • Forcing speed increases resistance

Slowing conversations:

  • Builds trust

  • Reduces defensiveness

  • Enables deeper alignment

Here, throughput is not speed, but quality of connection.


4. Why Slowing the Constraint Works Systemically

Across all examples, slowing the constraint improves outcomes because it:

  1. Reduces economically destructive volume

  2. Filters demand toward higher value

  3. Preserves scarce capacity

  4. Shapes behavior rather than serving it blindly

  5. Protects long-term capability and trust

These effects are invisible if throughput is defined only as “units per time.”


5. A TOC Reinterpretation: Exploitation vs. Protection

From a TOC standpoint, these cases suggest a refinement:

  • Some constraints should be exploited

  • Others should be protected

  • Still others should be intentionally throttled

The decision depends on the constraint’s role in achieving the goal.

A critical diagnostic question is:

Does increasing flow through this constraint increase or dilute value?

If value is diluted, slowing the constraint is the rational choice.


6. Conclusion

Slowing the constraint is not an abandonment of TOC principles, but their mature application. In systems where constraints govern cost, behavior, perception, or human capability, speed is not leverage—control is.

The ultimate lesson is clear:

The purpose of a system is not to move faster.
The purpose of a system is to achieve its goal.

When slowing the constraint serves that goal, it is not only acceptable—it is essential.
