Spain's 1970s Diet Was Worse, Yet People Were Thinner

Worse Food, Thinner Bodies: The Sedentary Lifestyle Bill

The generation raised in the 1970s and 80s ate lard on bread for breakfast, industrial pastries for snacks, and questionable processed meats for dinner. And they were thin. This isn't nostalgia; it is a measurable contradiction. Data indicates that 60.9% of the Spanish population is overweight or obese, and 13% are diabetic. If people ate worse before, why didn't they gain weight?

The most common answer is energy expenditure. Life back then involved walking, running, and jumping. Today’s life involves sitting.

Food Quality: Lard vs. Palm Oil

Some argue that while not healthy, the food of that era was more authentic. Others note that a 1970s ice cream could contain 78% fat, mostly saturated, but meat was real and expensive, and fruit and vegetables were local and seasonal. Pastries used lard; now they use palm oil and additives. The difference isn't eating a donut, but that today processed food is cheap and ubiquitous. In the middle of all this is bread: white bread has a glycemic index around 70, nearly identical to table sugar.

Why White Bread Is Compared to Sugar

On a scale where glucose scores 100, white sugar scores 70, as does white bread. Baguettes reach 80-90, with no clear explanation. According to calculations: 100 grams of white bread equals about 50 grams of sugar, roughly ten packets. Someone eating half a baguette consumes a significant portion of their daily sugar allowance without realizing it. The full breakdown, with equivalencies and blood glucose curves, is far scarier than the summarized figure.

This leads to radical stances: no bread, no sugar, nothing labeled. One specialist reportedly recommended eliminating all packaged products from the diet after a serious oncological diagnosis. While this improves general health, the account admits it doesn't always prevent the inevitable.

Sedentary Lifestyle: The Undisputed Factor

Opposing views agree on one thing: kids back then moved. Food wasn't better; energy expenditure was much higher. From home to school, from school to the street playing soccer until dark. Now, the route is home-school-home, and the rest of the time is spent on screens. The summary phrase: in a group of kids back then, there was the fat one; now there is the skinny one.

Caloric balance allows little interpretation. Consuming 3,000 kilocalories while burning 2,000 accumulates 1,000 daily. A kid in the 70s burned off a bollycao (a popular chocolate-filled pastry) by running; a kid today eats it in front of a computer. The result is a generation growing up with empty calories and half the movement.

Shocking Statistics

The cited numbers are scandalous. In the United States, 40% of adults are obese, and the total of diagnosed, undiagnosed, and prediabetic individuals would reach half the adult population. In Spain, 13% are diabetic, rising to 31% among older adults. Annual diagnoses, numbering in the hundreds of thousands, continue to grow.

A reasonable objection arises: if almost everyone consumes more sugar than recommended, why does only a part get sick? The counterargument is that damage accumulates invisibly. There are more smokers without lung cancer than with it, which doesn't absolve tobacco. The same applies to sugar.

Not All Black and White

There were also obese people in the 70s and 80s. Abundance showed in those who could afford it, while others worked and ate just enough. Some recall summers of activity without gyms and defined abs, while others argue nostalgia distorts memory: many back then had extra pounds, society just didn't penalize them.

Bread returns to the center of the debate. One case involves a 90-year-old relative who has eaten bread with tomato for breakfast for half a century and remains healthy. The sensible reading: the problem isn't an occasional donut, but making it the basis of the diet. Damage comes from accumulation.

Where Analysis Stalls

With these elements, the reason the 1970s generation was thinner seems obvious: less processed food and more movement. But no one can measure the exact weight of each factor. Was it pastries, the sofa, hidden sugar, or population aging? Those who eat normally and live to 90 debunk closed theories. Those who binge on refined foods and fall ill before 50 reinforce them. The analysis stops right there, with bread in the crosshairs and no single culprit.
