When it comes to foods, you’ve probably heard the terms processed, minimally processed, and ultra-processed tossed around — and there’s a clear hierarchy. Minimally processed foods are better for you than processed foods, which are better for you than ultra-processed foods. What’s unclear is what differentiates the three from one another. For example, where is the line drawn between processed and ultra-processed foods?
If you’re a little confused, don’t worry! I get it — and I’ve got you covered.
Minimally Processed Foods
Of the three types of foods we’re discussing today, minimally processed foods are the closest to unprocessed foods and don’t contain any added fats, salt, or sugar. Minimally processed foods are only slightly altered from the natural plant or animal to simplify transportation, storage, and preservation and ensure the food remains safe to eat.
Take fresh lettuce, for example. Before being sold at the store, it may be pre-washed, cut into smaller pieces, and packaged. Similarly, milk is pasteurized and refrigerated before being sold, while we often buy meat that has already been trimmed of fat and vacuum-packaged. Other examples of minimal processing include grinding, fermenting, drying, roasting, boiling, and freezing.
We see minimal processing for many fruits, vegetables, meats, nuts, and whole grains — and most of it’s completely healthy. After all, cutting broccoli into florets, drying fruits, or freezing meat or seafood counts as minimal processing!
Processed Foods
Processed foods differ from minimally processed foods in that they have added salt, sugar, fat, or starch ingredients. Typically, processed foods contain two to three components (or more) and are ready to be eaten without additional preparation.
These foods undergo additional processing like canning, bottling, and non-alcoholic fermentation to ensure they are easier to prepare and have a better storage life or flavor. (Think freshly made bread, canned fish, salted nuts, certain cheeses, beans in brine, and some smoked meats.)
Ultra-Processed Foods
Ultra-processed foods are exactly what they sound like. They’re foods that have been highly processed. Instead of merely including additional salt, sweeteners, or fat, ultra-processed foods contain artificial colors and flavors as well as preservatives that increase palatability, preserve texture, and lengthen shelf life. NOVA, a well-known diet classification system, says that ultra-processed foods are “snacks, drinks, ready meals, and many other products created mostly or entirely from substances extracted from foods or derived from food constituents with little if any intact food.”
Like processed foods, ultra-processed foods are typically ready to eat without much additional preparation. However, unlike minimally processed foods and processed foods, ultra-processed foods require several processing steps and ingredients, such as bulking agents, color stabilizers, hydrolyzed protein isolates, emulsifiers, maltodextrin, fructose, modified oils, and humectants.
Chicken nuggets, hot dogs, veggie burgers, energy bars and drinks, sweetened breakfast cereals, ice creams, white bread, soft drinks, frozen meals … the list goes on.
Why Processed Foods Are So Appealing
Chances are you eat a lot of ultra-processed foods each day — and you’re not alone. In fact, ultra-processed foods make up roughly 60% of the average adult’s diet, and it makes sense.
We love these foods because they taste good. They’re relatively cheap and are ready to be eaten with little-to-no additional prep, meaning you can save time and even gain essential nutrients. Yes, even ultra-processed foods provide vital nutrients like protein, iron, and various vitamins. For example, fruits and vegetables frozen immediately after harvest will retain most of their vitamin C. Some foods can even be fortified with specific nutrients, such as iron, B vitamins, folic acid, iodine, and vitamin D, to prevent everything from rickets to goiter.
Additionally, processing via pasteurization, cooking, or drying can sometimes slow or destroy the growth of harmful bacteria, while emulsifiers can make our foods more appealing to eat. Notably, emulsifiers prevent peanut butter from separating into solid and liquid parts.
Why Processed Foods Should Be Eaten In Moderation
Processed foods aren’t inherently bad, and you shouldn’t avoid them altogether. However, you’ll want to be careful when it comes to ultra-processed foods. When possible, you’ll want to opt for foods in their least-processed form because ultra-processed foods:
Can harm your health: Eating too much ultra-processed food can lead to high blood pressure, breast and colorectal cancer, and even impaired cognition when you’re older.
Don’t contain as many nutrients: Processing of any kind can remove or destroy nutrients. Peeling off the outer layers of fruits, vegetables, or whole grains removes fiber and phytochemicals, while heating or drying foods can destroy additional vitamins and minerals.
Can increase your risk of weight gain: What’s more, eating too many processed foods can lead to weight gain. This is especially true for ultra-processed foods, as they contain a high ratio of calories to nutrients yet aren’t usually particularly filling. The result? You’ll probably eat or drink a lot before you begin to feel full, all while consuming lots of calories. In a study published by Cell Metabolism, the group on an ultra-processed diet consumed roughly 500 more calories per day than those on the unprocessed diet when allowed to eat as little or as much food as they wanted. The ultra-processed group also gained two pounds on average over fourteen days, while the unprocessed group lost weight.
If you’re trying to lose weight or get in shape, you need to pay attention to what you’re eating. Limit your intake of ultra-processed foods and listen to your body. However, nutrition can only get you so far. You’ll also want to exercise!
