Ultra-processed foods (UPF's), a term coined by Carlos Montieros, a famous Brazilian nutritional epidemiologist, are being blamed for all kinds of woes these days including the rise in obesity, heart disease, type 2 diabetes and many other types of chronic diseases. Ranging from twinkies to hotdogs, cold cereals to doritos, UPF's make up over 50% of the average American diet. That's a lot of twinkies! But what are they and are they really as bad for your health as all that? Well, according to a study published in 2024 in the British Medical Journal that included data from over 9 million people, UPF's can make you sick to the tune of increased risk of anxiety, depression, obesity, metabolic syndrome, certain cancers including colorectal cancer and premature death. From a culture that routinely feeds its children goldfish crackers as the snack of choice, maybe it's time to make some changes? But first it's helpful to understand how processed foods are classified because some of them are really good for you! Dr. Montieros created a classification system called Nova (the Latin word for "new") that is now being used all over the world. Nova classifies foods into four categories: Unprocessed or minimally processed foods, like fresh or frozen fruits and vegetables, beans, lentils, meat, poultry, fish, eggs, milk, plain yogurt, rice, pasta, corn meal, flour, coffee, tea and herbs and spices. Processed culinary ingredients, such as cooking oils, butter, sugar, honey, vinegar and salt. Processed foods made by combining foods from Category 1 with the ingredients of Category 2 and preserving or modifying them with relatively simple methods like canning, bottling, fermentation and baking. This group includes freshly baked bread, most cheeses and canned vegetables, beans and fish. These foods may contain preservatives that extend shelf life. Ultraprocessed foods made using industrial methods and ingredients you wouldn’t typically find in grocery stores — like high-fructose corn syrup, hydrogenated oils and concentrated proteins like soy isolate. They often contain additives like flavorings, colorings or emulsifiers to make them appear more attractive and palatable. Think sodas and energy drinks, chips, candies, flavored yogurts, margarine, chicken nuggets, hot dogs, sausages, lunch meats, boxed macaroni and cheese, infant formulas and most packaged breads, plant milks, meat substitutes and breakfast cereals. Similarly, the Academy of Nutrition and Dietetics ranks processed foods from minimally to mostly processed: Minimally processed foods, such as fresh blueberries, cut vegetables and roasted nuts, are simply prepped for convenience. Foods processed at their peak to lock in nutritional quality and freshness include canned tomatoes or tuna, and frozen fruit or vegetables. Foods with ingredients added for flavor and texture, such as sweeteners, spices, oils, colors and preservatives, include jarred pasta sauce, salad dressing, yogurt and cake mixes. Ready-to-eat foods, such as crackers, chips and deli meat, are more heavily processed. The most heavily processed foods often are frozen or premade meals, including frozen pizza and microwaveable dinners. Minimally processed foods have a place in healthy diets. For example, low-fat milk, whole-grain or wheat breads, precut vegetables and fresh-cut greens are considered processed foods. Also, milks and juices may be fortified with vitamin D and calcium, while breakfast cereals may have added fiber. And canned fruits packed in water or natural fruit juice can be part of a healthy diet when fresh fruit isn't easily available.

A five-year study of over 100,000 people found that every 10 percent increase in consumption of ultra processed food was associated with a 12 percent higher risk for cancer. Too much sugar, sodium and fat. Heavily processed foods often include unhealthy levels of added sugar , sodium and fat . These ingredients make the food we eat taste better, but too much of them leads to serious health issues like obesity, heart disease, high blood pressure and diabetes . Lacking in nutritional value. Heavy processing strips many foods of their basic nutrients, which is why many foods today are fortified with fiber, vitamins and minerals. Calorie dense and addicting. It’s very easy to overindulge in unhealthy food and consume more calories than we realize. For example, an Oreo cookie contains about 50 calories , while an entire cup of green beans is only 44 calories. Processed foods like these are also designed to stimulate our brain’s “feel-good” dopamine center, making us crave more of them in the future. Quicker to digest. Processed foods are easier to digest than unprocessed, whole foods. That means our bodies burn less energy (hint: calories) digesting them. It’s estimated we burn half as many calories digesting processed foods compared to unprocessed foods. This fact combined with the calorie density of processed foods in general can make it easy to pack on the pounds. Full of artificial ingredients. There are about 5,000 substances that get added to our food. Most of them have never been tested by anyone other than the company using them. That includes additives to change color, texture, flavor and odor as well as ingredients like preservatives and sweeteners.

There are so many delicious choices out there, fruits, veggies, whole grains, lean proteins, nuts, seeds, legumes...the list is extensive. The change from UPF's to whole foods will certainly change your life and health for the better. Exercise is man's best medicine --Hippocrates
