Think about the last time you genuinely cooked from scratch on a weekday evening. Not reheated something. Not ordered from an app. Actually cooked. For millions of people around the world, the answer to that question changed dramatically somewhere around March 2020, and honestly, things have never quite gone back to normal since.
The COVID-19 pandemic did something no war, no economic crash, no food trend, and no celebrity diet ever managed to do at scale: it rewired how the entire planet eats. Quietly, suddenly, and permanently. From snacking habits in Poland to food delivery apps in China, the evidence is staggering. Let’s dive in.
Home Cooking Made a Historic Comeback
Before the pandemic, the world was already cooking less and less. Research suggests that a decline was underway in home cooking, skills, and confidence in a number of countries including the UK, the USA, Canada, and Australia. The pandemic flipped that trend almost overnight. The lockdown led to a massive rise in home cooking, with roughly two in five participants in one French study cooking more frequently, as barriers such as time constraints were reduced.
The pandemic left a significant mark on consumption habits, with the vast majority of consumers saying they altered their eating habits as a result of the pandemic, according to a study by the International Food Information Council. Specifically, among those who made any change, the biggest shift was that nearly three in five Americans reported cooking at home more, while roughly a third said they were snacking more and thinking about food more than usual.
People in the U.S. continued to cook more, with a large majority saying they would keep doing so after the pandemic ended, driven by increased creativity and confidence in the kitchen, as well as the motivation that cooking at home helps save money and eat healthier. It wasn’t just America. This was genuinely global.
Snacking Became the New Normal
Here’s the thing about being stuck at home for months: the kitchen is always right there. Always. Unhealthy snacking was among the few food behaviors that increased significantly since the pandemic, with most of the items in this category being snacks consumed by participants. It’s one of those findings that, when you read it, makes you think, “well, obviously.”
For the groups that did increase their snacking habits, experts suggested a link to increased psychological distress and uncertainty, a phenomenon known as emotional eating. Increased snacking habits were also associated with individuals who already had a higher body weight. In other words, people who were already struggling were the most likely to reach for the chips.
The amount of food consumed as snacks during lockdown increased in Canada, Denmark, Poland, and the UK, suggesting this was a widespread, cross-cultural response rather than a regional quirk. Stress eating, it turns out, has no passport.
Food Delivery Exploded Into Something Entirely New
The online food delivery market gained a great deal of traction from the COVID-19 pandemic, and the growth could be seen in almost every market. Before 2020, food delivery was growing steadily but still felt like a luxury. The pandemic turned it into infrastructure. The COVID-19 pandemic significantly accelerated the adoption of food delivery services as lockdowns and social distancing measures restricted in-person dining, and many restaurants pivoted to delivery and takeout to survive.
The food delivery market experienced significant growth year over year since 2017, with an exponential surge from 2019 through 2020, driven by the increasing demand for food delivery services among consumers. The pandemic also sped up the evolution of the dining restaurant sector and spawned ghost kitchens and a culture of eating on the go, with ghost restaurants that operate with no traditional dine-in space becoming prevalent as a means to meet greater demand for delivery.
Online Grocery Shopping Crossed a Point of No Return
Due to the coronavirus pandemic, online delivery orders surged in the United States. Up to roughly seven in ten grocery shoppers purchased non-perishable packaged foods like cereals online in 2021, while in 2017 the number was closer to six in ten. That shift sounds modest on paper, but the real story is in the permanence of it.
How consumers choose to receive their online grocery orders has changed significantly, with delivery recently dethroning pickup as the most popular fulfillment method. Delivery sales have increased by roughly two fifths since the start of 2021, the highest growth rate among all fulfillment categories.
I think the most striking part isn’t the pandemic surge itself. It’s that the habit stuck. Since April 2020, grocery delivery and pickup sales remained well above five billion dollars per month in the United States. Particularly among older generations, consumers seemed keen on continuing to buy groceries online in the future. A generation that had never used an app for groceries became regular users. That’s not a small thing.
Restaurant Culture Took a Blow It’s Still Recovering From
Restaurants didn’t just close. Many of them never reopened. The COVID-19 pandemic impacted the functioning of food systems globally, and all over the world, food businesses were disturbed by isolation, strict lockdowns, and the suspension of nearly all activities. The restaurant industry absorbed one of the largest economic shocks in its modern history, practically overnight.
Just under two fifths of European consumers said they would be relying on ready meals less regularly than before lockdown, and a large majority said the same of eating in restaurants. The decreasing popularity of restaurants was partially explained by concerns about COVID-19 exposure but also by collapsed spending power.
Even now, in 2026, the ghost of that disruption is still felt. Many dining concepts shifted permanently toward hybrid models, takeout-first menus, and delivery partnerships. The restaurant you loved in 2019 probably looks very different today, if it still exists at all.
Diet Quality Shifted, But Not Consistently
In general, changes in eating habits during the pandemic seemed mixed and controversial, varying between and within countries, life stage, and socioeconomic backgrounds. This is the part of the story that gets overlooked. The pandemic didn’t just make everyone eat better or worse. It split people in two directions, sometimes in the same household.
The exceptional circumstances of lockdown provided a positive opportunity for some people to improve their diet quality by spending more time cooking or eating more fresh products including fruits and vegetables. By contrast, other participants reported a decline in their diet quality, mainly caused by the consumption of comfort food, snacking, or food supply issues.
While positive cooking-related practices and increases in fruit and vegetable intake were found in some populations, an increase in saturated fat intake was also seen. With the additional pressure on individuals’ physical and mental health, the essentiality of maintaining a balanced diet was highlighted. Basically, the pandemic was a nutrition mirror: it reflected and amplified whatever habits you already had.
Emotional Eating Became a Recognized Behavioral Pattern
If the pandemic taught us anything about ourselves, it’s that we eat our feelings. Loudly. For the groups that did increase their snacking habits, experts suggested a link to increased psychological distress and uncertainty, a phenomenon known as emotional eating. Research published in 2024 on behavioral nutrition confirmed that emotional eating patterns became more common, particularly among people experiencing anxiety or isolation.
Parents with children under 18 saw their food concerns and routines particularly disrupted, with a significantly higher share snacking more as a result of the pandemic. Parents were also more likely to eat when feeling emotional, compared to those without children.
Think of emotional eating as the nutritional equivalent of doom-scrolling. You know it’s not helping you, but the circumstances make it almost inevitable. At times of severe social disruption, be that war, conflict, pandemic, or economic downturn, both the availability and consumption of healthy dietary patterns can be adversely affected. When the COVID-19 pandemic hit and lockdown restrictions followed, households were reported to consume unhealthy diets. In some cases, this seemed to be a response to the situation and a coping mechanism.
Food Insecurity Reached Crisis Levels Worldwide
While some households were experimenting with sourdough recipes, others were going hungry. That contrast tells the full story of the pandemic’s impact on food. The most recent estimates indicate that as many as 161 million additional people experienced chronic undernourishment in 2020 as the pandemic took hold, with the number of people facing moderate or severe food insecurity rising by some 320 million people.
Supply chain disruptions due to COVID-19 and increased consumer demand for food drastically raised food prices across the globe, increasing the severity of food insecurity for the hundreds of millions of people around the world who go to bed hungry every night. Approximately 713 to 757 million people globally, and one out of every five people in Africa, were still suffering with hunger in 2023, after COVID-19.
It’s hard to say for sure how long the full consequences of this will be felt, but the numbers are sobering. The pandemic didn’t just change how the wealthy world eats. It removed food access from millions of people entirely.
Supply Chain Disruptions Rewrote What’s Available and at What Price
Airline closures, national and international restrictions, and lockdowns severely disrupted the food supply chain. Along with structural weaknesses in the world food system, these exposed more people to food crisis and acute hunger. This wasn’t just a temporary inconvenience. Empty shelves in supermarkets in 2020 signaled something deeper: global food systems are far more fragile than most people ever imagined.
Since 2020, a series of events affected both income and prices. Supply chain bottlenecks began during the COVID-19 pandemic and were exacerbated in 2022 by Russia’s invasion of Ukraine, leading to uncertainty around the passage of grain supplies from the Black Sea region. What started as a pandemic problem became a prolonged global food pricing crisis.
The COVID-19 pandemic increased global food insecurity in almost every country by reducing incomes and disrupting food supply chains. For consumers in higher-income countries, this showed up as higher grocery bills and product shortages. For those in lower-income countries, the effects were far more severe and lasting.
Some Habits Stuck: The Long-Term Legacy Through the Mid-2020s
We are now in 2026, and the question isn’t whether the pandemic changed eating habits. It’s which changes turned out to be permanent. Research addressed the two-year legacy of social distancing times caused by the COVID-19 pandemic on eating habits across diverse populations worldwide. The social and sanitary policies during the pandemic substantially affected the schedules and lifestyle of many people, with longer periods staying at home and lasting consequences on their eating habits and food choices.
There remains a need to intervene on eating habits both to maintain the positive changes and to focus on reducing the negative changes observed during the COVID-19 pandemic, mainly caused by mental health challenges and sedentary lifestyles. This points toward important directions for public policies and clinical practice in the field of nutrition.
The convenience food reliance, the hybrid grocery shopping model, the food delivery habit, and the heightened awareness of health and immunity are all still very much visible trends. More time spent at home, increased flexibility in working hours, and the opportunity to work from home have been identified as factors that contributed to some positive changes in eating patterns and food preparation approaches that persisted well beyond the initial pandemic period. The pandemic didn’t just interrupt our routines. It rewrote them.
