Navigating the World of Ultra-Processed Foods: What You Need to Know

Ultra-processed foods (UPFs) are a growing part of the American diet, sparking debate about their impact on health. Although completely eliminating them may not be realistic or even necessary, understanding what they are and how they affect the body is crucial for making informed dietary choices. This article explores the nuances of UPFs, offering insights into which ones can still fit into a balanced lifestyle and how to prioritize whole, minimally processed foods.

What Are Ultra-Processed Foods?

Defining ultra-processed foods can be tricky, but most research relies on the NOVA Food Classification System [1, 4]. This system categorizes foods into four groups:

• Group 1: Unprocessed or minimally processed foods
• Group 2: Processed culinary ingredients
• Group 3: Processed foods
• Group 4: Ultra-processed foods

According to the NOVA classification, ultra-processed foods typically contain five or more ingredients, often including additives like flavorings, emulsifiers, and sweeteners, and substances not commonly used in home kitchens [1] and [2]. Yet, the degree of processing doesn’t automatically dictate a food’s nutritional value [1].

Experts note that ultra-processing can alter how foods affect the body, potentially influencing fullness, digestion, blood sugar response, and the likelihood of overeating [1]. Studies suggest that higher consumption of UPFs is associated with increased calorie intake and a greater risk of obesity, heart disease, type 2 diabetes, and other chronic conditions [3].

Five “Ultra-Processed” Foods That Can Fit Into a Healthy Diet

While prioritizing whole and minimally processed foods is recommended, some ultra-processed options can still be part of a balanced diet, providing nutrients and convenience [1].

Protein Powder

Protein powder is a refined form of protein extracted and isolated from sources like milk or peas, classifying it as ultra-processed [1]. However, it can be helpful for meeting protein needs, especially for athletes, individuals recovering from illness, or older adults with chewing difficulties. It’s important to check ingredient lists and choose products that have been independently tested for safety and efficacy [1].

Plant-Based Milks

Soy milk and other plant-based milks are often considered ultra-processed due to additives like emulsifiers or added sugars [1]. However, they can be high-quality, nutrient-dense options, particularly for those with food allergies, dietary restrictions, or vegan/vegetarian preferences. Fortified soy milk provides essential nutrients like calcium, vitamin D, potassium, and fiber [2]. Opting for unsweetened varieties is recommended.

Flavored Tofu

Flavored tofu, such as pre-marinated varieties, is categorized as ultra-processed, while plain tofu is considered “processed” [1]. Despite this distinction, tofu remains a valuable plant-based protein source. Choosing plain tofu and seasoning it yourself is a good option for those aiming to limit ultra-processed foods.

Canned Beans with Sauce

Canned beans are a convenient way to increase fiber intake, but those with added sauces or sugars are classified as ultra-processed [1]. Prioritizing canned beans with little to no added sugar and lower sodium is advisable.

Yogurt with Added Sugar

Yogurts with added sugars, stabilizers, or preservatives fall into the ultra-processed category [1]. Choosing plain or no-added-sugar varieties is recommended to avoid excessive sugar intake. Mixing unsweetened yogurt with a small amount of sweetened yogurt can be a compromise.

Key Takeaways

• Ultra-processed foods are not inherently “bad,” but limiting their intake is generally wise.
• The NOVA classification system helps categorize foods based on processing levels.
• Focus on the overall nutritional value and ingredient list when choosing foods.
• Prioritize minimally processed foods while allowing some ultra-processed options for convenience and enjoyment.

context matters. Increasing intake of minimally processed foods like fruits, vegetables, whole grains, beans, eggs, and proteins is beneficial, even while still consuming some ultra-processed foods [1].
