Nutrition advice has been changing since people started paying attention to nutrition, which, depending on who you ask, was sometime around the mid-1980s.
Before that, food was simpler. You ate what your mother made, what the school cafeteria served, what the grocery store had on sale, and nobody spent twenty minutes reading the back of a package.
There were no apps tracking macros. No ingredient lists going viral on social media. No influencer telling you that the thing you’ve been eating your whole life is going to shorten it.
People raised in the 60s and 70s grew up in a different nutritional universe, one where the government’s food guidelines were still being written, and most families operated on a simple rule: if it fills you up and you can pay for it, it’s dinner.
A lot of what they ate without a second thought would make a modern tracking app go into system overload.
1. Bologna sandwiches on white bread
This was lunch. For years, sometimes every day of the week. Two slices of white bread, a few rounds of bologna, a smear of yellow mustard, maybe a leaf of iceberg lettuce if someone was feeling fancy.
The bread was refined flour with the fiber and most of the nutrients processed out. The bologna was processed meat, which in 2015 the World Health Organization classified as carcinogenic, the same evidence-based category as tobacco.
Not equally dangerous, but linked to cancer with the same level of certainty.
Nobody’s mother knew that in 1974. She was packing a lunch that was cheap, fast, and filling, and the kid was happy to eat it. That sandwich powered an entire generation through elementary school.
2. Jell-O molds with things suspended in them
Lime Jell-O with shredded carrots. Orange Jell-O with cottage cheese. Strawberry Jell-O with canned fruit and little marshmallows. These were called salads. They were brought to potlucks. People were proud of them.
The technique involved dissolving a packet of artificially flavored, artificially colored gelatin in boiling water, stirring in whatever needed to be used up from the fridge, and pouring it into a mold to set overnight.
The result was a wobbling, translucent dome with things trapped inside it, served on a leaf of lettuce as if that made it a vegetable.
Today’s nutrition apps would flag the sugar, the artificial dyes, and the sodium. The person who made it would tell you it was the prettiest thing on the table, and they wouldn’t be wrong.

3. Tang
Tang was marketed as what the astronauts drank in space, which was technically true (NASA used it on Gemini missions) and that was enough to make an entire generation of parents believe it was good for their kids.
The pitch was vitamin C. The reality was sugar, citric acid, artificial flavor, and artificial color, mixed with water and served in a tall glass at breakfast like it was orange juice.
It wasn’t orange juice. It wasn’t close to orange juice. But the space program was the most exciting thing in America, and if John Glenn drank it, it was going in the kitchen.
4. TV dinners on aluminum trays
Swanson put an entire meal in a divided aluminum tray, froze it, and told America to warm it up and eat it in front of the television. Salisbury steak in one compartment.
Mashed potatoes in another. Corn, or peas, or a square of something that was called a brownie.
The sodium in a single tray could run over a thousand milligrams. The ingredient list included things most home cooks had never heard of and wouldn’t have been able to pronounce.
But the convenience was the point. A working mother could put dinner on the table in twenty-five minutes without a single pot, and in the 60s and 70s, that was something nobody was going to argue with.
5. Everything made with Crisco
Pie crusts. Fried chicken. Cookies. Biscuits. Anything that needed to be flaky, crispy, or golden went through a can of Crisco first. Procter & Gamble introduced it in 1911, and by the middle of the century it was in nearly every American kitchen.
Crisco was partially hydrogenated vegetable oil, the primary source of artificial trans fats, which raise bad cholesterol and lower good cholesterol at the same time.
The FDA didn’t ban partially hydrogenated oils until 2018, roughly a century after Crisco hit the shelves. By then, generations of pie crusts had already been eaten.
Nobody’s grandmother was trying to feed them trans fats. She was making the pie the way her mother made it, and the can was right there on the counter next to the flour.

6. Kool-Aid made with a full cup of sugar
The recipe on the back of the packet called for one cup of white sugar per pitcher. One cup.
Stirred into water with a powder packet of artificial flavor and artificial color, poured into a plastic pitcher, and served to every kid in the neighborhood all summer long.
The product hasn’t changed; those unsweetened packets still call for the same amount of sugar today. What changed is that parents started paying attention. By the 90s, mothers were diluting it or switching to juice boxes.
In the 60s and 70s, nobody was counting grams of sugar because nobody was counting grams of anything. The Kool-Aid was cold, and the kids were thirsty, and that was the end of it.
7. Liver and onions
This one was served on purpose, as health food. Iron, B vitamins, protein. The doctor might have recommended it.
Your mother definitely made you eat it, and if you didn’t like it, that was your problem, because it was good for you and you were going to sit there until the plate was clean.
Liver is still nutritious; that part hasn’t changed.
What’s changed is that nutritionists now flag it for extremely high levels of vitamin A, which in excess can cause toxicity, and for cholesterol content that would have been a concern if anyone had been measuring cholesterol in 1972.
Also, because the liver filters toxins, it can accumulate heavy metals and pesticide residues depending on the animal’s diet and environment.
None of that was on anyone’s radar. Liver was the thing you fed a child who looked pale, and it worked.
8. Casseroles made with canned cream-of-mushroom soup
Tuna casserole. Green bean casserole. Chicken and rice bake. The base of an entire decade of weeknight dinners was a ten-ounce can of cream-of-mushroom soup, and nobody was reading the label because the label wasn’t the point.
The ingredient list, if anyone had looked: modified food starch, monosodium glutamate, soy protein concentrate, vegetable oil, and enough sodium to turn a simple casserole into something a cardiologist would bring up at your next visit.
One can contained more than half a day’s recommended sodium, and most recipes called for at least one.
But it was the recipe. It was the recipe your mother used and the recipe on the back of the can and the recipe in the church cookbook. It made dinner easy. Plus, it tasted fine, and that was all it needed to do.

9. Margarine, sold as the “healthy” choice
Margarine wasn’t just tolerated; it was recommended. Doctors told patients to switch from butter.
The American Heart Association’s guidelines against saturated fat steered families straight toward it. Margarine was marketed for decades as the heart-healthy alternative, the modern choice, the thing smart families put on their toast.
It was trans fat in a tub. The same partially hydrogenated oils that the FDA would eventually ban in 2018 were being spread on toast every morning by people who thought they were doing the right thing for their health.
Every authority in their life told them they were.
Nobody was being reckless or ignoring warnings
The warnings hadn’t been written yet.
These were parents feeding their families with what was available, what was affordable, and what every grocery store, cookbook, and doctor in the country said was fine.
The fact that the science caught up doesn’t mean the people who ate it were careless. It means the information arrived late, the way it usually does, about a generation after the damage was already in the pantry.
