You probably already know that certain sections of the grocery stores have healthier foods than other. Experts recommend you should generally stick to the outer perimeter where the fresh produce, meat, fish, and dairy products are located while avoiding those center aisles with all the processed foods.

But sticking to the outside and skipping the inside keeps you away from some potentially healthy, convenient, waste-free foods. One category was suffering in recent years with lower sales due to changing consumer tastes. Find out which section of the grocery store is having a major comeback (page 4) thanks to an unlikely group of fans: millennials.

Millennials grocery shop differently

As a group, millennials have slightly different grocery shopping habits compared to their parents. They are more likely to look for convenient food options and are willing to pay a premium for them. They’re also the least likely group to use a shopping list (or only make them at the last minute) and are ready and willing to try new products. These traits make them a grocery store marketers dream.

They’re more frugal than you think 

Sure, millennials love their Seamless and Grubhub apps, but a surprising number of them are cooking for themselves rather than wasting money on takeout or dining at restaurants for every meal. Between exorbitant city rent payments, student loans, and dismal salaries, they can’t afford to overspend on food all the time.

They hate being wasteful

Throwing away food isn’t something millennials like to do if they can avoid it. That’s one reason they buy fewer groceries at once and aren’t the most likely group to join warehouse clubs like Costco and Sam’s Club.

Millennials are bringing back frozen foods 

According to Bloomberg, the volume of frozen food sales is on the rise for the first time in the last five years. Brands like Banquet frozen dinners, Eggo waffles, and Stouffer’s entrees are growing in popularity despite the fact that they don’t fit in with the current trend toward fresh, farm to table foods. It turns out that millennial shoppers are flocking to the frozen food section.

Frozen foods have a few surprising benefits

So why do millennials love frozen food so much? It’s simple. These meals are easy to prepare and easy to portion. They generate less waste since they have a longer shelf life than fresh foods. Plus, millennials are often only cooking for themselves, so single-serving options are an inexpensive way to make just the right amount of food.

Frozen food can be healthy

Even before the renaissance of frozen food, there were plenty of healthy options hiding out in the freezer cases right next to the ice cream. Frozen vegetables, for example, can be even healthier than fresh veggies since they’re flash frozen at the peak of ripeness.

Meanwhile, savvy companies like Green Giant are jumping on the low carb bandwagon and offering pasta alternatives such as riced cauliflower and zucchini noodles. All these nutritious goodies can be found in the freezer aisle.

Frozen foods are great for vegans 

Millennial vegans can find a bevy of options in the freezer aisle, too. Meatless burgers and other vegetarian or vegan options often have entire sections devoted to them in the frozen cases.

Millennials want to eat at home

Frozen foods allow millennials to create healthy meals at home without spending a ton of money. They’re like those pricey meal delivery kits — without the prep work or inflated pricing. For now, frozen food is the way of the future.
