# Cost of a 1960s Diet vs Modern Food Costs by Decade > The following is a result from ChatGPT's "deep research" feature when asked to analyze what a "1960s diet" would cost in each subsequent decade. > The CPI and basket of goods is constantly adjusted to "reflect consumer purchasing behavior", but this metric overlooks the fact that _consumer behavior itself is guided by prices_. Just because someone _does_ buy something doesn't mean they would _prefer_ this good over another (potentially superior) good, all it tells you is that they _did_ buy it. When the cost of living off of higher quality foods becomes too great to bear, consumers will trade-down to lower-quality foods. When the CPI reflects this, even a "steady inflation number" hides the fact that **quality of life** has degraded. > If you don't want to read the whole thing, at least check out the conclusion at the end. Everything from here down was generated by the AI after rounds of nudging by me. > Also the cover image, obviously (lol) Following a **1960s-style diet** – rich in red meat, dairy, and unprocessed “whole” foods – has become increasingly expensive over time. Below we examine each decade from 1960 to the present, tracking how much the cost of that fixed 1960s diet rose and comparing it to the **prevailing food costs (CPI)** shaped by consumers adapting their eating habits. Key staples like red meat, dairy, grains, and processed foods are highlighted to show the impact of inflation on a traditional diet versus switching to cheaper substitutes. ## 1960s: Baseline of Affordable Abundance - **Percentage Increase in Cost:** Food prices rose modestly in the 1960s (around **2–3% per year**). Over the decade, maintaining the same 1960 basket led to roughly a **25–30% increase** in cost ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1960%2424.38%200.91,0.35%25%201968%2428.06%203.24)). This was a relatively small jump compared to later decades. - **Cost in Era’s Currency:** For example, if a household spent **$100 per week in 1960** on the typical foods (plentiful beef, whole milk, butter, eggs, etc.), by **1970** that same diet cost about **$125–$130** in nominal dollars. Everyday items were cheap: ground beef was only **$0.30 per lb in the late 1950s**, and butter about **$0.75 per lb ([Grocery Store Prices for 14 Items in 1957 | HowStuffWorks](https://money.howstuffworks.com/Grocery-store-prices-for-14-items-in-1957.htm#:~:text=4%3A%20Ground%20Beef)) ([Grocery Store Prices for 14 Items in 1957 | HowStuffWorks](https://money.howstuffworks.com/Grocery-store-prices-for-14-items-in-1957.htm#:~:text=When%20they%20weren%27t%20cooking%20with,fashioned%20butter%20today))**. Americans could afford more of these foods as incomes grew. - **Comparison to CPI (Behavior-Adjusted):** The official food Consumer Price Index (CPI) climbed at a similar pace (~28% increase from 1960 to 1970 ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1960%2424.38%200.91,0.35%25%201968%2428.06%203.24))), since consumer behavior hadn’t drastically shifted yet. Few felt pressure to substitute cheaper foods because inflation was mild. In fact, many families **ate more** of these staples as prosperity rose – U.S. **beef consumption per person increased from ~63 lbs in 1960 to 84 lbs by 1970**, while chicken rose from 28 to 48 lbs ([National Chicken Council | Per Capita Consumption of Poultry and Livestock, 1965 to Forecast 2022, in Pounds](https://www.nationalchickencouncil.org/about-the-industry/statistics/per-capita-consumption-of-poultry-and-livestock-1965-to-estimated-2012-in-pounds/#:~:text=1960%2063,5)). Any cost savings from “behavior changes” were minimal in the 60s. (One early example: margarine was already replacing some butter for health/cost reasons, but butter was still affordable in 1960 at ~$0.75, so sticking to butter didn’t break the bank ([Grocery Store Prices for 14 Items in 1957 | HowStuffWorks](https://money.howstuffworks.com/Grocery-store-prices-for-14-items-in-1957.htm#:~:text=When%20they%20weren%27t%20cooking%20with,fashioned%20butter%20today)).) Overall, adapting one’s diet wasn’t necessary for budget reasons in the 1960s, as **food was relatively cheap and inflation low**. ## 1970s: Soaring Prices Hit Traditional Diets Hard - **Percentage Increase in Cost:** The 1970s brought **surging food inflation**. A fixed 1960s-style diet would cost roughly **double (+100% or more)** by the end of the decade. In particular, **meat and dairy prices skyrocketed**. Beef prices **roughly doubled** from 1970 to 1980 (the BLS beef index jumped from the 40s to nearly 100 ([Beef and veal price inflation, 1935→2025](https://www.in2013dollars.com/Beef-and-veal/price-inflation#:~:text=17,386))), contributing to an overall ~**120% increase** in the cost of a meat-heavy 1960s basket during the 70s. By comparison, overall food-at-home prices rose about **121%** in that span ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1973%2438.45%2016.30,1981%2473.39%207.30)) – a huge jump in itself. The worst spikes came in 1973–74, when food prices jumped **15–16% in a single year ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=,Bureau%20of%20Labor%20Statistics))**. - **Cost in Era’s Currency:** Someone stubbornly sticking to their 1960 grocery list in this era paid a steep price. If they spent $100 per week in 1970, by **1980** they’d need to spend roughly **$220–$230** for the same items. For instance, mid-decade a pound of steak that cost ~$1 in the late 60s might cost $2–3 by the late 70s. Whole milk prices also roughly **doubled** in the 70s ([Fresh whole milk price inflation, 1939→2024](https://www.in2013dollars.com/Fresh-whole-milk/price-inflation#:~:text=32,324)). This era’s inflation was so severe that it forced a re-budgeting for those insisting on expensive staples. - **Comparison to CPI (Behavior-Adjusted):** While **all** consumers felt the 70s price shock, those who **adapted their diets mitigated the impact**. Many Americans reacted by **buying less red meat or switching to cheaper proteins**. Notably, when beef became very expensive (meat prices jumped **5.4% in just one month in early 1973 ([1973 meat boycott - Wikipedia](https://en.wikipedia.org/wiki/1973_meat_boycott#:~:text=Meat%20prices%20began%20to%20rise,3))**), consumers staged a “meat boycott” and turned to poultry, pork, or beans. Poultry was a big winner – chicken prices did rise (44% in 1973 ([Fresh whole chicken price inflation, 1935→2024](https://www.in2013dollars.com/Fresh-whole-chicken/price-inflation#:~:text=,Bureau%20of%20Labor%20Statistics))), but over the decade chicken remained cheaper per pound than beef, and **per capita chicken consumption climbed while beef consumption dropped** ([National Chicken Council | Per Capita Consumption of Poultry and Livestock, 1965 to Forecast 2022, in Pounds](https://www.nationalchickencouncil.org/about-the-industry/statistics/per-capita-consumption-of-poultry-and-livestock-1965-to-estimated-2012-in-pounds/#:~:text=1978%2087,0)). Processed and shelf-stable foods also gained favor as thrifty alternatives; for example, consumers might buy canned soups or powdered drink mixes which had smaller price increases. The **official CPI (which reflects some substitution)** still rose dramatically (~**105%** for food in the 70s ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1973%2438.45%2016.30,1981%2473.39%207.30))), but the true **cost of living was a bit lower for those who adapted**. By cutting back on expensive items (or stretching them – e.g. more casseroles with grains/veggies and less meat), families could keep their food spending increase somewhat below the headline inflation. In short, a person clinging to the high-red-meat, butter-on-everything diet of 1960 ended up paying **much more** in the 70s, whereas those who embraced **cheaper substitutes (chicken instead of steak, margarine instead of butter, generic and processed foods)** softened the blow. The late 1970s also saw food costs stabilize under price controls, rewarding those who diversified their diet away from the costliest staples. ([Chicken leads U.S. per person availability of meat over last decade | Economic Research Service](http://www.ers.usda.gov/data-products/charts-of-note/chart-detail?chartId=105929)) *Per capita availability of meat in the U.S., 1910–2021. **Beef** (gray line) peaked in the 1970s and then declined as prices rose and consumers ate more **chicken** (yellow line). Chicken overtook beef as the most consumed meat by 2010, thanks to its lower cost and dietary shifts ([Chicken leads U.S. per person availability of meat over last decade | Economic Research Service](http://www.ers.usda.gov/data-products/charts-of-note/chart-detail?chartId=105929#:~:text=The%20supply%20of%20chicken%20available,9%20pounds%20per%20person)). Pork (red) held roughly steady, while fish (purple) remained a small share. This illustrates how Americans adjusted their protein sources over decades in response to price and preferences.* ([Chicken leads U.S. per person availability of meat over last decade | Economic Research Service](http://www.ers.usda.gov/data-products/charts-of-note/chart-detail?chartId=105929#:~:text=The%20supply%20of%20chicken%20available,9%20pounds%20per%20person)) ## 1980s: Slowing Inflation and New Dietary Habits - **Percentage Increase in Cost:** Inflation cooled in the 1980s, making food prices more stable. Even so, a fixed 1960s diet saw about a **50% cost increase** over the decade. That means the same basket that cost $100 in 1980 would cost around **$150 by 1990**. This increase was much lower than the 70s, but still notable. Meats and dairy had smaller price jumps now (beef rose ~38% from 1980–90, milk ~45% ([Fresh whole milk price inflation, 1939→2024](https://www.in2013dollars.com/Fresh-whole-milk/price-inflation#:~:text=32,324))), and overall food-at-home prices climbed ~**40–50%** ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1979%2463.33%2010.81,1987%2486.60%204.32)) ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1989%2496.14%206.57,1997%24122.41%202.49)) in the 80s. - **Cost in Era’s Currency:** If our traditional-diet shopper spent $220/week in 1980 (continuing the prior example), by **1990** they’d be spending roughly **$330** for the same groceries. For instance, a gallon of whole milk that cost about $1.50 in 1980 might be ~$2.20 by 1990; a pound of ground beef around $1.20 in 1980 could be ~$1.75 in 1990. These nominal increases were easier to manage than the wild 70s, but still added up. - **Comparison to CPI (Behavior-Adjusted):** In the 80s, **consumer behavior had permanently shifted** due to the prior decade’s lessons. Many households continued to favor **cheaper or leaner foods**, and this helped keep their actual cost of living lower than if they had stuck to the old diet. For example, **butter consumption plunged** (per capita fell from 7.5 lbs in 1960 to ~4.5 lbs by 1980) as people used margarine and processed spreads instead ([cameracopy4.qxd](https://ers.usda.gov/sites/default/files/_laserfiche/publications/41035/15333_aer780g_1_.pdf?v=74489#:~:text=commodity%2C%20illustrates%20the%20underlying%20dynamics,the%20processed%20dairy%20products%20group)). Butter lost its hefty weight in the price index, reflecting how few people still bought it regularly by the 80s. Similarly, beef was no longer king – Americans were eating **20% less beef than in the 70s, and far more chicken**, which was mass-produced cheaply ([Chicken leads U.S. per person availability of meat over last decade | Economic Research Service](http://www.ers.usda.gov/data-products/charts-of-note/chart-detail?chartId=105929#:~:text=The%20supply%20of%20chicken%20available,9%20pounds%20per%20person)). The **CPI’s market basket was updated in 1987**, locking in these new habits (more poultry and convenience foods, fewer expensive staples). As a result, **official food inflation** in the 80s was moderate, and those who already had adapted their diet felt roughly the same ~50% rise as the CPI. However, someone who *refused* to change – still buying large quantities of red meat, whole milk, fresh butter, etc. – would have spent **more** than the average person. They missed out on the savings from things like **economy cuts of meat, bulk grains, and processed goods** that became popular. By the late 1980s, the U.S. food system was delivering **cheaper calories** (e.g. refined grains, corn oil, sweeteners) on a huge scale. Families that incorporated these cheaper ingredients (think Hamburger Helper, microwave dinners, soda instead of milk) kept their grocery bills lower. Indeed, food became a smaller share of household spending: it fell from **28.5% of the family budget in 1960 to about 17% by 1980 ([cameracopy4.qxd](https://ers.usda.gov/sites/default/files/_laserfiche/publications/41035/15333_aer780g_1_.pdf?v=74489#:~:text=A%20review%20of%20changing%20weights,All%20items))**, a testament to how adapting food choices and benefitting from cheaper options lowered the relative cost of living. ## 1990s: Cheaper Alternatives in an Era of Low Inflation - **Percentage Increase in Cost:** The 1990s saw **very low food inflation** by historical standards. Maintaining the exact 1960s diet through this decade would raise costs by only about **25–30%**. Food-at-home prices increased roughly **2–3% per year** or **~27% total from 1990 to 2000 ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1989%2496.14%206.57,1997%24122.41%202.49)) ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1997%24122.41%202.49,2005%24146.89%201.93))** – similar to general inflation. - **Cost in Era’s Currency:** Continuing our scenario, $330/week in 1990 for a 1960-style diet would become about **$420–$430/week by 2000**. Many staple food prices barely crept up. For example, a loaf of bread or a dozen eggs only rose by a few dimes over the whole decade. In some cases prices even stagnated or fell: U.S. farm commodities were abundant (grain surpluses kept costs of cereal, flour, and animal feed low). The late 90s had such cheap raw ingredients that milk, meat, and sugar prices were relatively stable. - **Comparison to CPI (Behavior-Adjusted):** By the 90s, **behavior-adjusted costs were markedly lower** than our fixed diet scenario, because consumers had spent two decades optimizing their food spending. The **prevailing diet in the 90s was very different from the 60s**, driven by cost efficiency and convenience. Shoppers embraced warehouse clubs and discount supermarkets, bought **private-label/store brands**, and leaned heavily on **processed foods** that benefited from cheap oil and corn. For instance, instead of whole fresh foods for every meal, families might use instant pasta mixes, boxed cereals, and soft drinks – items produced at scale and often cheaper per calorie. This kept **average grocery bills lower**. In fact, the cost of living for food rose so slowly in the 90s that it was common to “trade up” some items (like occasionally buying steak or exotic fruits) and still stay on budget. A person strictly sticking to a 1960s whole-food diet (cooking from scratch, lots of fresh meat and dairy) would **not** enjoy those processed-food savings. By this time they’d be paying **noticeably more** than the average consumer for the same caloric intake. Studies began to note a troubling pattern: **healthier whole foods were getting relatively more expensive, while unhealthy processed options remained very cheap**. (For example, fresh produce prices in the U.S. rose faster than soda and snack prices in the 80s/90s.) The overall CPI for food was low in the 90s, reflecting these substitutions. A clear sign of the era: **fast-food value meals and junk snacks proliferated**, offering calories at rock-bottom prices. Those who adapted their diet to include these inexpensive foods saw a **much lower increase in their cost of living** – and in some cases, food spending as a share of income hit record lows. Meanwhile, someone clinging to only unprocessed “old-fashioned” foods would have a higher grocery bill and experienced a higher effective inflation than the behavior-adjusted CPI. In short, the 1990s made it **easier than ever to save money on food – if you were willing to eat like a 1990s consumer**. ## 2000s: Diverging Diet Costs – Whole Foods vs Processed - **Percentage Increase in Cost:** Food costs in the 2000s rose at a modest pace, very similar to the 90s. A fixed 1960s diet would increase about **25–30% in cost** over the decade (roughly keeping up with general inflation). From 2000 to 2010 the food-at-home CPI climbed ~**29%** ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1997%24122.41%202.49,2005%24146.89%201.93)) ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=2005%24146.89%201.93,2013%24181.02%200.90)). There were a couple of price spikes mid-decade (e.g. 2007–2008 saw grain and dairy price jumps), but also some years of minimal change. - **Cost in Era’s Currency:** Our hypothetical shopper spending $420 in 2000 would be around **$540 per week by 2010** for the same basket. Key 1960s staples did get pricier in the 2000s: e.g. whole milk went from about $2.80/gal in 2000 to $3.50+ by 2010; ground beef from ~$1.80 to ~$2.25/lb over the decade. But the increases were gradual. Notably, by 2010 many traditional items (meats, eggs, dairy) were **cheaper in real terms than in the 1970s** – thanks to efficiency gains – even if nominal prices edged up. - **Comparison to CPI (Behavior-Adjusted):** The 2000s is when the gap between a “traditional whole-food diet” and the **average diet’s cost** really started to widen. The official CPI remained fairly low, in part because consumers kept shifting towards **cheaper ingredients and prepared foods**. Two diverging trends emerged: - Many consumers, facing tight budgets especially after the 2008 recession, doubled down on **low-cost, energy-dense foods**. This meant more refined grains (white bread, pasta, rice), processed snacks, sweetened drinks, and fatty meats – all of which were inexpensive and often on promotion. These items benefited from globalized supply chains and agricultural surpluses, keeping their prices down or rising very slowly. For example, corn-based sweeteners and oils were so cheap that soda and fried foods remained very affordable in the 2000s. - On the other hand, some consumers began seeking **healthier “whole” foods** (organic produce, whole grains, lean meats). But these often came at a premium and saw higher inflation. Someone maintaining a 1960s-style home-cooked diet (lots of fresh ingredients) fell into this category almost by definition. They would have experienced **higher effective inflation** than the average. Research confirms this divergence: in recent analyses, the **cost of a healthy recommended diet has risen faster than the cost of an unhealthy diet**. For instance, during 2019–2022, prices of healthy foods (fruits, veggies, lean proteins, etc.) jumped **12.8% in one year**, whereas “unhealthy” food prices rose only **7–9%** ([ Healthy Food Prices Increased More Than the Prices of Unhealthy Options during the COVID-19 Pandemic and Concurrent Challenges to the Food System - PMC ](https://pmc.ncbi.nlm.nih.gov/articles/PMC9967271/#:~:text=diet%20cost%20increased%2017.9,less%20affordable)). This pattern had been building over the 2000s. Thus, those who **adapted by buying the cheapest processed options saw a smaller cost-of-living increase** than those buying whole foods. By the end of the 2000s, the U.S. was in a situation where **following a 1960s diet cost significantly more than an average 2000s diet**, even though overall inflation was mild. In practical terms, a family could slash their grocery bill by switching from fresh-cooked dinners with milk to, say, boxed mac-and-cheese with soda – and many did. The CPI implicitly captured this shift: food remained about ~13% of consumer spending in the 2000s (near historic lows), partly because people found ever-cheaper ways to eat. ## 2010s: Relative Stability (Until a Shock) - **Percentage Increase in Cost:** The 2010s were a decade of **exceptionally low food inflation**. A fixed 1960s diet’s cost rose only about **15–20%** in total through 2010–2019. For most of those years, food prices grew less than 2% annually (some years even saw slight deflation in grocery prices ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=2011%24175.09%204.80,0.20%25%202018%24185.51%200.45%25%202019%24187.14%200.88))). From 2010 to 2020 the food-at-home index went up about **16%** ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=2009%24166.51%200.47,0.20)) ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=2017%24184.68,2024%24237.27%201.19)) – the slowest growth of any decade in this analysis. - **Cost in Era’s Currency:** In our running example, $540/week in 2010 for the old-fashioned diet would become roughly **$620–$630 by 2020**. In other words, nearly flat in real terms. Many staple food prices were remarkably steady. A gallon of whole milk hovered around $3.50–$4 throughout the decade; a pound of chicken breasts stayed near $1.99 for years. The **shale oil boom** and low energy costs, plus technological advances in agriculture, helped keep food production and transportation cheap. By the late 2010s, Americans enjoyed some of the **lowest food inflation on record**. - **Comparison to CPI (Behavior-Adjusted):** With inflation so low, the difference between sticking to a 1960s diet and the average diet’s cost was less pronounced *during* this decade – everyone benefited from stable prices. However, it’s important to note that by the 2010s the **average diet was very far removed from the 1960s diet**, largely for economic reasons built up over prior decades. The average American in 2019 was consuming lots of inexpensive processed foods and far less of the pricey whole foods that defined 1960. This meant their cost of living was inherently lower. For those still following a traditional diet, their basket cost hadn’t risen much in the 2010s, but it was starting from a **much higher base** relative to typical consumers. In effect, the “gap” was already baked in. Government data continued to show that **healthy food plans cost more** – a trend consistent with the idea that a whole-food diet remained pricier than the mix of convenience foods most people bought. By the end of the 2010s, food was only about 12–13% of household expenditures on average, reflecting decades of substitutions and cheaper alternatives keeping costs down ([cameracopy4.qxd](https://ers.usda.gov/sites/default/files/_laserfiche/publications/41035/15333_aer780g_1_.pdf?v=74489#:~:text=A%20review%20of%20changing%20weights,All%20items)). A person eating like it’s 1960 (lots of red meat roasts, fresh veggies, whole milk) in 2019 would likely be spending well above that share. In summary, the 2010s offered a **breather**: low inflation meant even “old diet” holdouts weren’t punished by price hikes, but they were still paying more than those who had long ago adapted to the economical 2010s food landscape. *(Note: The **early 2020s** have seen a sharp inflationary spike for food, largely due to pandemic disruptions and war. Interestingly, this spike hit fresh foods and meats harder than processed foods, echoing the long-term pattern. For example, in one study the cost of a healthy diet rose **17.9%** from 2019–2022, whereas the typical less-healthy diet rose **9% ([ Healthy Food Prices Increased More Than the Prices of Unhealthy Options during the COVID-19 Pandemic and Concurrent Challenges to the Food System - PMC ](https://pmc.ncbi.nlm.nih.gov/articles/PMC9967271/#:~:text=diet%20cost%20increased%2017.9,less%20affordable))**. This underscores that when inflation strikes, sticking to a traditional wholesome diet tends to *cost more* than making do with cheaper substitutes. As of 2022–2023, consumers again coped by buying store brands, cutting meat consumption, etc., to soften the blow – much as they did in the 1970s.)* ## **Conclusion: Traditional Diet vs Adaptive Diet – Which Costs More?** Over six decades, inflation has raised all food prices, but **not uniformly**. Someone maintaining a fixed 1960s-style diet from 1960 through today would have seen their food costs rise far more than the official “cost of food” suggests – because the official index assumes people adjust their buying. In fact, by 2020 such a person would be spending roughly **8–10 times** what they spent in 1960 on food in nominal dollars, whereas the behavior-adjusted CPI for food rose about 8-fold ([Beef and veal price inflation, 1935→2025](https://www.in2013dollars.com/Beef-and-veal/price-inflation#:~:text=Between%201935%20and%202025%3A%20Beef,beef%20and%20veal%20was%20higher)) ([Fresh whole chicken price inflation, 1935→2024](https://www.in2013dollars.com/Fresh-whole-chicken/price-inflation#:~:text=are%20805.12,02%20difference%20in%20value)). That implies perhaps a **20–25% higher cumulative cost** for the fixed diet follower. The biggest contributors were **red meat and dairy:** these had higher-than-average inflation over the long run. For example, beef prices rose much faster than overall prices (3,637% since 1935) ([Beef and veal price inflation, 1935→2025](https://www.in2013dollars.com/Beef-and-veal/price-inflation#:~:text=According%20to%20the%20U,45%20difference%20in%20value)), while chicken (a cheaper substitute) had lower inflation (805% since 1935) ([Fresh whole chicken price inflation, 1935→2024](https://www.in2013dollars.com/Fresh-whole-chicken/price-inflation#:~:text=are%20805.12,02%20difference%20in%20value)). Consumers responded accordingly – eating less beef and butter, and more chicken and margarine, as decades passed. Grains and processed foods, often mass-produced from low-cost commodities, helped keep modern diets affordable; whole foods did not see such dramatic cost efficiencies. In each decade, **those who adapted their food choices enjoyed a lower cost of living increase** than those who stuck with the old-school diet. The 1970s illustrated this vividly (households that substituted chicken or pasta when steak prices spiked avoided some of the worst budget pain). By the 2000s and 2010s, the **typical American diet was heavily “behavior-adjusted” for cost** – full of cheaper oils, sweeteners, and protein sources – which kept the **CPI food inflation** relatively low. Meanwhile, a person trying to eat like it’s 1960 (lots of red meat, whole milk, homemade meals) ended up paying a premium each year to do so. In summary, **inflation heavily penalized the maintenance of a 1960s diet**. Each decade saw that fixed basket get relatively more expensive, especially for categories like red meat and dairy. In contrast, Americans who embraced **cheaper substitutes and new foods** managed to keep their food spending growth below the inflation that a “fixed basket” would imply. This behavior-adjustment – switching from costly whole foods to economical processed and alternative foods – has been a key reason the **reported CPI for food** rose more slowly. It quantifies how much lower the cost of living was for those who adapted: often shaving **several percentage points off per-year inflation**, and cumulatively making food far more affordable than it would have been under the old diet. The trade-off, of course, is that while the **traditional 1960s diet was nutritious but now expensive**, the **modern adapted diet is cheaper but often less healthy**. Consumers effectively used substitutions to **counteract food inflation**, saving money at the expense of dietary changes. The decades-long outcome is clear – financially, **eating in 2023 like it’s 1963 will cost you significantly more** than eating like a 2023 consumer, due to the compounding effect of differential inflation and behavior shifts over time. **Other Sources:** - U.S. Bureau of Labor Statistics – Historical CPI data for food categories ([Food at home price inflation, 1947→2024](https://www.in2013dollars.com/Food-at-home/price-inflation#:~:text=1973%2438.45%2016.30,1981%2473.39%207.30)) ([Beef and veal price inflation, 1935→2025](https://www.in2013dollars.com/Beef-and-veal/price-inflation#:~:text=17,386)) - USDA Economic Research Service – Food price reports and consumption trends ([Chicken leads U.S. per person availability of meat over last decade | Economic Research Service](http://www.ers.usda.gov/data-products/charts-of-note/chart-detail?chartId=105929#:~:text=The%20supply%20of%20chicken%20available,9%20pounds%20per%20person)) ([cameracopy4.qxd](https://ers.usda.gov/sites/default/files/_laserfiche/publications/41035/15333_aer780g_1_.pdf?v=74489#:~:text=commodity%2C%20illustrates%20the%20underlying%20dynamics,the%20processed%20dairy%20products%20group)) - *The Value of a Dollar* – mid-20th-century grocery prices (e.g. 1957 butter, beef) ([Grocery Store Prices for 14 Items in 1957 | HowStuffWorks](https://money.howstuffworks.com/Grocery-store-prices-for-14-items-in-1957.htm#:~:text=4%3A%20Ground%20Beef)) ([Grocery Store Prices for 14 Items in 1957 | HowStuffWorks](https://money.howstuffworks.com/Grocery-store-prices-for-14-items-in-1957.htm#:~:text=When%20they%20weren%27t%20cooking%20with,fashioned%20butter%20today)) - Congressional Research Service – Food inflation and consumer responses ([1973 meat boycott - Wikipedia](https://en.wikipedia.org/wiki/1973_meat_boycott#:~:text=Meat%20prices%20began%20to%20rise,3)) - Academic study on healthy vs unhealthy diet cost inflation - ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC9967271/#:~:text=diet%20cost%20increased%2017.9,less%20affordable))
