Walk into any grocery store, and you’ll see up to 40,000 products. You have access to hundreds of brands, flavors, packaging options, and health claims, which makes the options feel abundant. And while choices surround you, most of your calories still come from just three crops: wheat, rice, and corn.

That gap between perceived variety and actual food sources says a lot about how the modern food system works. 

Most people don’t realize how concentrated the system has become. A grocery store might carry 20 different types of cereal, but many of them rely on the same base ingredients, processed in slightly different ways and marketed as something new.

That illusion of variety makes it harder to see how dependent we’ve become on a narrow set of crops, all of which are not very nutrient-rich, and production methods that further deplete the nutritional quality of our food.

In this article, we’ll break down how we got here, from the shift to industrial agriculture and factory farming to soil depletion, nutrient changes in food, and the rise of ultra-processed diets. We’ll also look at how corporate consolidation and food marketing shape what ends up on your plate, and what “real food” actually means in today's world.

How Food Used to Work

For most of human history, food didn’t come from a supply chain. It came from nearby land and eventually from local farmers, who sent their crops and goods to nearby markets.

Animals were raised outdoors or were hunted. Plants were grown in mixed fields, rotated seasonally, and shaped by climate and soil conditions. Meals were built from foods that looked like food, not formulations.

Food also required more involvement. People spent more time harvesting and preparing meals, preserving food, and working with raw ingredients. That process naturally limited how much processing food went through before it was eaten.

There wasn’t even a need to define “real food.” It was just the default, as there weren't any other options.

Across different cultures living in various parts of the world, people ate in similar ways. Among ancestral diets:

• Whole animals were used, in a nose-to-tail approach, not just muscle meat
• Foods were eaten seasonally or preserved through fermentation
• Diets included a mix of plants and animal foods, depending on geography
• Soil, animals, and humans were part of the same cycle

Certain foods were consistently valued and sought out, including organ meats like beef liver, fish, eggs, and fish roe. These foods were often reserved for children, pregnant women, or people recovering from illnesses, since they were very nutrient-dense and helpful for building the immune system.

Some of these foods might seem trendy today, but in fact, they've been consumed for thousands of years and were always considered important.

How the Industrial Shift Changes Our Diets

The food system changed quickly over the last century. Mechanization, the use of synthetic fertilizers, pesticides, and refrigeration, all made it possible to produce and transport food at a scale never seen before. These innovations helped the global population grow from about 2.5 billion in 1950 to over 8 billion today.

Given how many people there were on earth to feed, the goal became clear: produce more food, more efficiently, at a lower cost.

So crop yields increased, prices have dropped, and seasonal foods have become more available year-round. However, the booming food supply wasn't based on nutrient density, soil health, or long-term sustainability. Those factors became secondary, and we've paid the price.

Efficiency solved one problem while creating others. Producing more food helped prevent widespread shortages, but it also shifted priorities away from how that food was grown and what it contained.

Factory Farming at Scale

Today, about 99% of farm animals in the United States are raised in concentrated animal feeding operations, also called CAFOs. These are large indoor systems designed to maximize output.

Animals are typically fed grain-based diets, even if their natural diet would be grass or forage. Living conditions are controlled to improve efficiency, but not to reflect the animals' natural environments. CAFO-raised animals tend to grow faster than they naturally would, which can affect the composition of the meat itself, including fat quality and micronutrient content.

Each year, around 10 billion land animals are slaughtered in the U.S. That works out to roughly 1 million per hour, and about 300 per second.

That level of production requires tight control over livestock feed, genetics, and growth rates. This type of system certainly produces a lot of food, but it also disconnects animal agriculture from the land it once depended on. For instance, the separation between animals and land also means manure is no longer returned to the soil in balanced ways, which used to help maintain soil fertility.

The Narrowing of Crops

At the same time, crop diversity has decreased dramatically. Three crops—wheat, rice, and corn—dominate global agriculture, accounting for roughly half of all calories consumed worldwide.

These crops are often grown in monocultures, meaning large areas are planted with a single species. Monocropping simplifies planting and harvesting, but it also leads to:

• Lower biodiversity
• Greater reliance on fertilizers and pesticides
• Increased vulnerability to pests and disease

Over time, this approach reduces resilience. When large areas depend on a single crop, problems can spread quickly, whether that’s pests, disease, or weather-related stress.

Another issue is that a large portion of these crops doesn’t even go directly to people. They’re used for:

• Animal feed
• Processed food ingredients
• Industrial uses

So while grocery shelves look full, it's mostly made of the same ingredients, many of which have consequences for the environment.

Corporate Control of Food

Food production has also become more centralized compared to the past. For example, in the United States, four companies, Tyson, JBS, Cargill, and National Beef, control about 85% of beef processing, hence why they're nicknamed "beef cartels."

That level of concentration influences how animals are raised, how food is processed, and what ends up in stores and at what prices. It also influences pricing structures, contracts, and even what farmers are allowed to grow or how they raise animals, which can limit flexibility at the farm level.

Farmers often have limited buyers, and consumers often have limited visibility into where their food comes from and how it's produced. Decisions about food are increasingly made far from where that food is actually grown or raised.

The Soil Crisis

Nearly 95% of the food we eat depends on soil to grow. Healthy soil contains microbes, fungi, and organic matter that support plant growth and nutrient content. It’s a living system that allows enough plants to grow to feed the global population.

Healthy soil acts almost like a sponge, holding water during heavy rain and releasing it during dry periods. As soil degrades, it loses that ability, which can lead to both flooding and drought stress in crops.

Today, topsoil is under strain, and soil degradation has become a major concern.

Soil degradation means the soil is losing the very things that make it productive and alive, including organic matter, microbial diversity, structure, and its ability to hold water and nutrients. 

Degraded soil becomes more like dirt over time, meaning it's less capable of supporting healthy plant growth and less able to deliver nutrients into the food we eat. Here’s what that looks like at scale:

• About one-third of global soil is already degraded and contains fewer nutrients than it did in previous generations
• Around 75 billion tons of topsoil are lost each year
• Projections suggest up to 90% of soil could be degraded by 2050

This matters because soil isn’t just where plants grow; it also directly affects how nutritious those plants are. When soil is depleted, crops might still grow, but they often contain fewer essential vitamins, minerals, and beneficial compounds.

Practices like monocropping, heavy tilling, and repeated use of chemicals like pesticides speed up this process by stripping the soil of its natural structure and biology. And when soil quality declines, plant quality often follows, and that impact carries all the way through the food system, from crops to animals to the nutrients that end up on your plate.

Nutrient Changes in Food

A comparison of crops from 1950 to 1999 found declines in several essential nutrients that we must get from our diets, including:

• Protein, which many people don't get enough of
• Calcium
• Iron
• Vitamin C

It was found that crops today have between 9-38% less of these nutrients than they did decades ago. 

Food today does, of course, still have nutritional value. 

But these findings suggest that higher yields don’t always equal higher nutrient density. If the soil is depleted, the plants grown in that soil tend to reflect that, which may be one reason certain nutrient deficiencies are common today, including in iron, magnesium, and vitamin B12.

Ultra-Processed Foods Take Over

The types of foods that people decide to eat on a daily basis have shifted along with production methods. 

The average adult living in the U.S now gets about 55% of their calories from ultra-processed foods (and kids often get even more).

These "food products" are made from refined ingredients, additives, and industrial formulations. They’re made to be convenient, shelf-stable, cheap, and tasty, which means people want to keep buying them over and over. 

These foods are designed to be hyper-palatable, meaning they combine salt, sugar, and fat in ways that encourage overeating. This makes them easy to consume in large amounts without feeling full, driving high-calorie intake and weight gain.

Examples of ultra-processed foods include packaged snacks like chips, cookies, and crackers, ready-made meals, sugary drinks, processed meats and cheeses, sugary yogurt and desserts, and many other products found in the center aisles of grocery stores (as opposed to the perimeter where the meat, fish, and produce tend to be).

High intake of processed foods is associated with increased risk of many health problems, including:

• Obesity
• Type 2 diabetes
• Cardiovascular disease
• Cancer

This shift in people's diets reflects how food is now produced, marketed, and consumed. As a population, we've never had access to so many inexpensive, palatable foods 24/7, and it's showing in terms of our declining health.

How Grocery Stores Shape Choices:

Inside stores, food placement impacts sales in many ways. Brands often pay for shelf space, especially at eye level, since products in those positions are more likely to be purchased.

Stores are typically arranged so that people buy more "junk" food. This layout guides behavior, usually without people noticing.

• Whole foods are around the perimeter
• Packaged foods fill the center aisles
• Impulse items, like candy and gum, are near the checkout

The Cheap Food Paradox

In 1930, Americans spent about 24% of their income on food. Today, that number is closer to 10%, which is less than half of what people used to allocate.

Food is more affordable than it used to be. But lower prices reflect tradeoffs in how food is produced. Environmental costs, soil degradation, and long-term health effects aren’t included in the price tag.

Healthcare spending has increased during the same period, especially for chronic conditions linked to poor diets, like obesity, diabetes, and heart disease. In other words, some foods might cost less at checkout, but the long-term costs often show up elsewhere, including in medical bills and reduced quality of life.

Food Waste on a Massive Scale:

Even with increased production, a large share of food never gets eaten. About 30-40% of all food in the U.S. is wasted. Globally, that adds up to around 1 billion tons each year.

If so much food is wasted, producing more doesn’t solve the problem on its own. Distribution and consumption patterns matter just as much as how much food we make.

What Is Real Food?

Real food is food that stays close to its natural form and comes from systems that support long-term health. Healthy food systems include:

• Foods grown in living soil
• Animals raised on pasture or in natural environments
• Minimal processing
• Higher nutrient density per serving

This aligns with ancestral diet principles. For most of human history, real food meant:

• Whole animals, including meat, organs, bone marrow, and connective tissue
• Seasonal plants
• Wild or pasture-raised animal foods

Foods like beef liver and other organ meats, eggs, shellfish, and fish roe were valued for their nutrient density and were part of everyday eating in many cultures. 

For example, liver is one of the highest sources of vitamin A, B12, and iron, while fish roe provides concentrated omega-3 fats, choline, and fat-soluble vitamins, nutrients that help support energy production, brain function, hormone balance, and overall nutrient status.

We might not consume these foods very often today, but it doesn't have to be that way, especially since we do still have access to these foods, including in desiccated supplement forms.

Bringing That Definition Into Today

The modern food system isn’t going away because it "works" in the sense that it feeds billions of people. But individual choices still influence demand.

You can move toward eating more real food and supporting a healthier food system by:

• Choosing whole foods more often than packaged ones
• Supporting farms that use pasture-based or regenerative practices
• Including a wider range of animal foods, not just muscle meat
• Paying attention to sourcing, not just labels

Ancestral supplements, in dessicated forms, like grass-fed beef liver and organ blends, make it easier to include nutrient-dense parts of the animal that were once commonly eaten but are often missing today. Options like wild-caught fish eggs or grass-fed colostrum reflect a similar principle, focusing on foods that naturally concentrate nutrients and support overall health.

• Grass-Fed Beef Liver: Rich in bioavailable vitamin A (retinol), B12, iron, and copper, supporting energy, immune function, and nutrient status
• Grass-Fed Beef Organs: A blend of liver, heart, kidney, and more, providing a broader spectrum of nutrients for metabolism, detox pathways, and overall resilience
• Wild-Caught Fish Eggs: A concentrated source of omega-3s (DHA and EPA), choline, and fat-soluble vitamins that support brain, hormone, and cellular health
• Grass-Fed Colostrum: Provides immunoglobulins, growth factors, and bioactive compounds that support gut barrier integrity, immune function, and recovery
• Ancestral Protein Powder: Made with bone broth, which provides collagen types I and III, along with hyaluronic acid, glucosamine, chondroitin, essential amino acids, and a blend of 12 superfoods

The Takeaway & Why This Still Matters

The current system produces large amounts of food, but that comes with serious tradeoffs:

• Soil degradation
• Reduced crop diversity
• Increased reliance on ultra-processed foods
• Centralized control of production
• Rising rates of chronic disease

Real food hasn’t disappeared, but it does require more intention to find and consistently choose over cheaper, widely available processed foods.

Nourishing foods used to be easy to recognize. Today, it takes more awareness.

We can all benefit from seeking out food that comes from healthy soil, raised or grown in ways that support natural systems, and consumed close to its original form. Every purchase shapes demand, and every meal reflects a set of choices. Those choices add up, both individually and collectively, and they still matter.
