Ultra\u2011processed foods (UPFs) are dominating modern diets.Let\u2019s unpack the research behind UPFs and learn how we can support healthier diet patterns in the real world without guilt or fear.What Are Processed Foods?There\u2019s no universal definition of the term processed foods. Processed food also doesn\u2019t mean ultra-processed food, even though many use these terms interchangeably.You should consider food along a spectrum from unprocessed to ultra-processed. The Nova system listed below classifies foods based on their degree of processing. It doesn\u2019t classify them based on how healthy or unhealthy they are:Unprocessed foods \u2014 These foods don\u2019t undergo any changes from their natural state. Examples include fruits, vegetables, and oats.Minimally processed foods \u2014 These foods are close to their natural state. Washing, cutting, pasteurizing, fermenting, freezing, or packaging them can alter them without eliminating their original nutrients. They don\u2019t have any added oils, fats, sugar, or other substances.Processed culinary ingredients \u2014 Pressing, grinding, crushing, or other processes extracted these products from natural foods. Examples include butter, salt, honey, and maple syrup. In moderation and with minimally processed foods or unprocessed foods, these ingredients can contribute to a more diverse diet. They can do this without compromising nutritional content.Processed foods \u2014 These foods have added ingredients (salt, oil, or sugar). They\u2019re there to enhance taste or improve shelf life while still keeping much of their nutritional value. Examples include canned beans, frozen vegetables, cheese, canned fish, and bread.Ultra\u2011processed foods \u2014 These industrially manufactured products include refined ingredients and additives. Examples include soda, candy, packaged snacks, instant noodles, sweetened cereals, frozen pizza, and energy bars. Their manufacturers aim to make them as tasty, convenient, and long\u2011lasting as possible. But they may lose nutrients in the process.Ultra\u2011processed foods include refined foods. They also include altered ingredients. These include:Artificial additives \u2014 Flavor enhancers, food dyes, stabilizers, and preservatives change taste, texture, and durability.Modified starches \u2014 Processed carbohydrates thicken or stabilize foods, far removed from whole grains or root vegetables.Refined flours \u2014 White flour loses bran and germ during processing, reducing fiber and vitamins.Refined oils \u2014 Hydrogenated or industrial seed oils, often modified to improve shelf life, have links to unhealthy fats.Refined sugars \u2014 Manufacturers of high\u2011fructose corn syrup and white sugar strip them of fiber and nutrients.UPFs aren\u2019t \u201cgood\u201d or \u201cbad.\u201d They\u2019re not nutritionally equal. The processing itself isn\u2019t always harmful all on its own.A Brief History of Ultra\u2011Processed FoodsUltra-processed foods make up nearly 60% of the average American diet. This is the case despite Americans\u2019 perception of them. Looking back at how ultra\u2011processed foods developed helps explain their powerful role in today\u2019s eating habits.Early preservationFood processing as we know it today started in the late 1800s and early 1900s. It focused mainly on safety and storage.Canning, pasteurization, and refrigeration allowed foods to last longer. They also reduced the risk of spoilage. These methods were necessary for feeding growing urban populations.Post\u2011World War II expansionIndustrial food production accelerated after the 1940s. Advances in chemistry and engineering led to the creation of additives and stabilizers.They also led to the development of artificial flavorings. Packaged snacks, frozen meals, and instant products became popular. This was because families sought convenience.Rise of global corporationsMultinational food companies were producing and marketing UPFs worldwide by the 1970s and 1980s. Aggressive advertising campaigns promoted sugary drinks and fast food as modern and desirable. These campaigns also promoted packaged snacks.Are All Processed Foods Unhealthy?Not all processed foods are created equal. Fortunately, processed foods can play a role in a healthy diet pattern. Frozen vegetables, canned beans, and plain yogurt are examples of nutritious processed items.Infant formula is an ultra-processed food. But many parents rely on it to properly nourish their children. This is especially the case when breastfeeding isn\u2019t an option.More negative health outcomes in children are likely without infant formula. These can include malnutrition and cognitive developmental delay.Another example of an ultra-processed food is protein powders. Many consumers opt for protein powders. They do this to enrich their diet and meet their nutritional needs.We should strive to eat minimally processed foods more often. Occasionally indulging in an ultra-processed food is perfectly fine. You can and should enjoy this without guilt.Fearmongering about processed foods may lead to unnecessary shame and anxiety around eating. Consider the overall diet pattern and reason for consuming the processed food.Healthy eating is a matter of budget and access to fresh foods. Many working families also have limited time to prepare food. A dietitian can help provide individualized nutrition advice on which foods can meet your nutritional needs.Health risks of UPFsUPF health risks aren\u2019t the result of one single ingredient. They\u2019re cheap and convenient. They\u2019re also engineered for taste.Their overall design makes them easy to overconsume while offering little nutritional value. This pattern increases the risk of obesity and heart disease. It also increases the risk of type 2 diabetes and certain cancers.UPFs share several features that directly affect the body:Excess salt \u2014 High sodium levels strain the cardiovascular system. This can raise blood pressure and contribute to hypertension.High calories, low nutrients \u2014 UPFs provide lots of energy but few vitamins and minerals. They also contain little fiber. This makes weight gain more likely.Hyper-palatability \u2014 Manufacturers engineer UPFs to taste so appealing that people often eat or drink more than they need.Refined sugars and starches \u2014 Eating these over time can lead to insulin resistance. It can also lead to type 2 diabetes.Unhealthy fats \u2014 Hydrogenated oils and trans fats raise low-density lipoprotein (LDL, or \u201cbad\u201d) cholesterol. They also lower high-density lipoprotein (HDL, or \u201cgood\u201d) cholesterol. This increases heart disease risk.Tips for Choosing Healthier Packaged FoodsYou don\u2019t need to avoid all packaged foods to eat well. The real skill is learning how to spot healthier options.You can make small changes that add up over time. For example:Choose whole foods \u2014 Fresh fruits, vegetables, and lean proteins undergo minimal processing. They also come packed with nutrients. Don\u2019t feel afraid to purchase canned, fresh, or frozen options.Cook at home \u2014 Making meals from scratch gives you control over ingredients and reduces reliance on UPFs.Limit sugary drinks \u2014 Water, tea, and sparkling water cut excess sugar.Overall, the research on processed foods is ongoing. You shouldn\u2019t oversimplify it. Everyone has different food preferences, nutritional needs, financial budgets, and access to food.Healthy eating is about finding a balance. It\u2019s not just the presence of processed foods. It\u2019s the overall pattern of your diet and lifestyle that matters.SourcesCurrent Obesity Reports.
