TV Dinners: The Birth of Ultra-Processed Convenience

Swanson’s TV dinners became the poster child of processed convenience in the 1970s, featuring aluminum trays filled with pre-cooked mystery meat smothered in artificial gravy. The original TV dinners came in four varieties—turkey, beef, fried chicken and Salisbury steak—each featuring a thick, gelatinous gravy made primarily of cornstarch, salt, and synthetic coloring. These meals contained sky-high sodium levels and partially hydrogenated oils that we now know create dangerous trans fats. Frozen meals are often heavily processed with extra salt and fat to make foods last longer, and companies typically use partially hydrogenated vegetable oils which are high in trans fats and adversely affect cardiovascular health.
Tang: The Artificial Orange Revolution

Tang powder promised astronaut nutrition but delivered nothing more than artificial flavoring and sugar in a bright orange package. The powdered drink mix contained zero real fruit juice, relying instead on synthetic vitamin C and artificial orange flavoring to create its signature taste. Ultra-processed foods from this era were often energy-dense, poor in nutrients, and inclusive of various synthetic additives such as emulsifiers, colors, artificial sweeteners, and flavor enhancers. What families thought was a healthy breakfast drink was actually just flavored sugar water with lab-created vitamins.
Hamburger Helper: Sodium-Packed Shortcut Meals

This boxed meal solution turned ground beef into what seemed like a complete dinner, but the pasta and seasoning packets were loaded with preservatives and enough sodium to rival seawater. The typical Hamburger Helper box contained over 800 milligrams of sodium per serving, not including the salt from the added ground beef. Modern research shows ingredients like high fructose corn syrup are linked to a higher risk of metabolic syndrome, with a 2023 study showing a 40% increased risk for those consuming it frequently. These convenient dinners normalized the idea that meals could come from boxes instead of fresh ingredients.
Wonder Bread: The Nutritionally Stripped Staple

Wonder Bread became America’s go-to sandwich bread despite being stripped of nearly all natural nutrients and pumped full of preservatives to achieve its unnaturally long shelf life. In the 1960s, bread typically included just flour, water, yeast, and salt, but modern bread might contain up to 12 additional components, including high fructose corn syrup and artificial preservatives. The bread’s soft, spongy texture came from chemical emulsifiers and dough conditioners that had never existed in traditional bread-making. This highly processed version lacked the fiber, vitamins, and minerals found in whole grain alternatives.
Frosted Flakes and Sugar-Coated Cereals

Breakfast cereals in the 1970s transformed from simple grains into sugar-delivery systems coated with artificial colors and flavors that turned milk into rainbow-colored liquid. Breakfast cereals now have 35% more ingredients than their earlier versions, with artificial colors and preservatives being common, according to a 2023 USDA report. The FDA hasn’t fully reviewed the safety of artificial dye in food since the 1970s and 1980s, so the agency’s approval still relies on older studies which couldn’t detect the neurobehavioral harms we now know about. Children were essentially eating candy for breakfast while parents believed they were providing proper nutrition.
Spam and Processed Lunch Meats

Canned meats like Spam became kitchen staples, but these products contained dangerous levels of sodium nitrates and nitrites used as preservatives and color enhancers. The United States is the leading country in ultra-processed food consumption, accounting for 60% of caloric intake, compared to a range of 14 to 44% in Europe. These processed meats also contained mechanically separated meat products and fillers that bore little resemblance to actual cuts of meat. The high sodium content and chemical preservatives have since been linked to increased risks of colorectal cancer and cardiovascular disease.
Velveeta and Processed Cheese Products

Velveeta and similar cheese products weren’t actually cheese at all, but rather emulsified combinations of cheese scraps, vegetable oils, and artificial stabilizers designed to melt smoothly. Ultra-processed foods often contain trans fats and high levels of saturated fats, which can raise LDL cholesterol levels and lower HDL cholesterol levels, with elevated LDL cholesterol being a major risk factor for atherosclerosis. These products contained artificial colors to achieve that distinctive orange hue and enough preservatives to remain shelf-stable for months. Real cheese requires refrigeration and has a much shorter lifespan than these processed alternatives.
Cool Whip and Non-Dairy Toppings

Cool Whip marketed itself as a convenient whipped cream alternative, but contained no actual cream—instead relying on hydrogenated oils, corn syrup, and artificial flavoring to mimic the real thing. Research has shown that eating ultra-processed foods, which are generally low in fiber, is detrimental to gut health because they tend to be easily digested with their components absorbed quickly into the bloodstream. The product’s unnaturally long freezer life came from chemical stabilizers that allowed it to maintain its texture for months. This synthetic dessert topping introduced families to the concept that artificial versions could replace natural dairy products.
Twinkies and Mass-Produced Snack Cakes

Hostess Twinkies epitomized the ultra-processed snack revolution with their indefinite shelf life achieved through a cocktail of preservatives, artificial flavors, and chemical stabilizers. Ultra-processed foods now make up more than half of what many Americans eat, and as rates of obesity, heart disease, and diabetes continue to rise, many health experts are asking if ultra-processed foods are making us sick. These individually wrapped cakes contained more chemicals than recognizable food ingredients, yet became a lunchbox staple for millions of children. The infamous “shelf life” myth became a cultural touchstone, highlighting just how far removed these products were from actual baked goods.
Jell-O and Artificial Gelatin Desserts

Jell-O transformed dessert-making with its convenient powder packets, but the colorful wiggly treats were essentially flavored gelatin loaded with artificial dyes and sweeteners. The use of food additives increased dramatically during the Industrial Revolution, with toxic compounds used liberally in factory food production, ranging from the coloring of cheese with red lead to sweets being colored green with copper arsenite. These desserts often contained artificial colors that had never been properly tested for long-term health effects. The bright, unnatural colors became normalized in American kitchens, conditioning families to accept artificially colored foods as normal.
Pop-Tarts and Toaster Pastries

Kellogg’s Pop-Tarts revolutionized breakfast by turning sugary pastries into a morning meal, complete with artificial fruit flavoring and enough preservatives to survive a nuclear winter. A 2024 review of 45 metanalyses covering nearly 10 million study participants found convincing evidence that a diet high in ultra-processed foods increases the risk of death from cardiovascular disease by 50% and anxiety by 48%, plus highly suggestive evidence of increased risks for heart disease death by 66%, obesity by 55%, and Type 2 diabetes by 40%. These “breakfast pastries” contained more sugar than most desserts and were marketed directly to children as nutritious meal replacements. The frosting and filling contained zero real fruit despite flavors like “strawberry” and “cherry.”
Instant Mashed Potatoes

Boxed instant mashed potatoes promised the comfort of homemade potatoes in minutes, but delivered a highly processed powder filled with preservatives, artificial flavors, and enough sodium to make your blood pressure monitor cry. The potatoes likely came from some kind of powder rather than real potatoes, but they did have a bit of real butter on top. These dehydrated flakes had been stripped of most natural nutrients during processing and required chemical additives to approximate the taste and texture of real mashed potatoes. Families lost the simple skill of boiling and mashing actual potatoes in favor of stirring mysterious powder into hot water.
Minute Rice and Instant Grain Products

Minute Rice and similar instant grain products sacrificed nutrition for convenience, pre-cooking rice to remove most of its natural vitamins and fiber before packaging it for quick preparation. Research shows a consistent decline in protein (6%), calcium (16%), phosphorus (9%), iron (15%), vitamin A (18%), riboflavin (38%), and vitamin C (15%) in 43 different fruits and vegetables over the past half century, with vegetables losing calcium (26.5%), iron (36.1%), vitamin A (21.4%) and vitamin C (29.9%) from 1975 to 1997. The processing methods used to create “instant” grains destroyed much of their nutritional value while adding preservatives to maintain shelf stability. What remained was essentially empty calories masquerading as a healthy grain serving.
The Lasting Impact on American Health

These convenience foods from the 1970s fundamentally changed how Americans thought about cooking and nutrition, normalizing the consumption of highly processed products over fresh, whole ingredients. Research highlights the high consumption of ultra-processed foods in all parts of the US population and demonstrates that intake has continuously increased in the majority of the population over the past 2 decades. What we are eating is making us sick, and ultra-processed foods seem to be a large driver, with Americans now living shorter lifespans than people in peer countries. The grocery aisles filled with these products created generations of consumers who grew up believing that food naturally came in colorful boxes and lasted for months without refrigeration, setting the stage for our current public health crisis.
