The CPI is a Lie: Keeping Up With Inflation Means Downgrading Your Diet

Inflation heavily penalized the maintenance of a healthy diet. Each decade saw such a diet get relatively more expensive, especially for categories like red meat and dairy. In contrast, Americans who embraced cheaper substitutes and new, processed foods managed to keep their food spending growth below the inflation that a healthy diet would incur. 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. But it obscures the fact that quality of life has dropped and health has declined.

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.

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.

(Chicken leads U.S. per person availability of meat over last decade | Economic Research Service) 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). 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.

(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 ). 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) (Fresh whole chicken price inflation, 1935→2024). 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), while chicken (a cheaper substitute) had lower inflation (805% since 1935) (Fresh whole chicken price inflation, 1935→2024). 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.
