What to eat on a non-UPF diet?: A Guide to Whole and Minimally Processed Foods

4 min read

According to a 2024 study, participants who reduced their Ultra-Processed Food (UPF) intake lost an average of 3.5 kg in just eight weeks, highlighting the significant impact of focusing on whole foods. If you're wondering what to eat on a non-UPF diet, this guide provides a roadmap to rebalance your plate and improve your overall well-being.

Quick Summary

A non-UPF diet prioritizes unprocessed or minimally processed foods. It focuses on fresh fruits, vegetables, whole grains, and lean proteins while reducing intake of foods with additives, high sugar, and unhealthy fats. The shift can lead to weight loss, improved mood, and better digestive health.

Key Points

  • Prioritize Whole Foods: A non-UPF diet focuses on foods as close to their natural state as possible, such as fresh fruits, vegetables, and whole grains.

  • Understand the NOVA Classification: Ultra-processed foods (UPFs) contain multiple industrial additives and ingredients not typically used in home cooking, unlike minimally processed or processed foods.

  • Swap for Simplicity: Replace packaged, sugary snacks with simpler whole-food alternatives like nuts, fruit, or unsweetened yogurt to reduce additives and unhealthy fats.

  • Cook More at Home: Preparing your own meals from scratch gives you complete control over ingredients, making it easier to avoid UPFs.

  • Read Ingredient Labels: When buying packaged items, check for short, recognizable ingredient lists and avoid products with numerous unpronounceable chemicals and additives.

  • Reap Health Benefits: Benefits of a non-UPF diet include better weight management, improved mood, and reduced risk of chronic disease due to higher nutrient density.

Understanding the Non-UPF Diet

A non-UPF diet revolves around consuming foods that are either unprocessed or have undergone minimal processing. According to the NOVA food classification system, ultra-processed foods are formulations made from substances extracted from foods, often with numerous additives, emulsifiers, and flavors not found in a home kitchen. In contrast, a non-UPF diet focuses on the first two categories: unprocessed/minimally processed foods and processed culinary ingredients. This approach minimizes intake of the calorically dense, nutrient-poor, and highly palatable products that can lead to overconsumption. The foundation of this way of eating is whole foods—items that are as close to their natural state as possible.

The Benefits of Eating Whole Foods

Adopting a non-UPF diet can have numerous positive effects on your health. By replacing ultra-processed products with whole foods, you can significantly reduce your intake of added sugars, unhealthy fats, and sodium. This shift aids in weight management, as whole foods tend to be more filling and less energy-dense. A diet rich in natural fiber from fruits, vegetables, and whole grains supports a healthy gut microbiome and aids digestion. Studies have also linked whole-food consumption with improved mental health, better sleep quality, and a lower risk of chronic diseases like heart disease and type 2 diabetes.

What to Fill Your Plate With

Protein Sources

  • Lean Meats and Poultry: Fresh chicken, turkey, beef, and pork are excellent choices. Opt for unprocessed cuts and prepare them with herbs and spices instead of pre-made sauces or marinades.
  • Fish and Seafood: Wild-caught or fresh fish like salmon, tuna, and mackerel are rich in omega-3s. Canned fish in water is also a minimally processed option.
  • Eggs: A versatile and protein-rich staple for any meal of the day.
  • Legumes: Beans, lentils, chickpeas, and peas are fantastic sources of fiber and plant-based protein. Use dried or canned versions with no added salt or sugar.
  • Plain Dairy: Unsweetened yogurt, milk, and simple cheeses can be part of a non-UPF diet. Check labels for minimal ingredients and no added sugars.

Carbohydrates

  • Whole Grains: Brown rice, quinoa, oats, barley, and whole wheat pasta are staples. Look for products clearly labeled as "100% whole grain".
  • Starchy Vegetables: Potatoes, sweet potatoes, and butternut squash are nutrient-dense carbohydrates that can be roasted, mashed, or baked.

Fruits and Vegetables

  • Fresh Produce: All fresh fruits and vegetables are non-UPF. Buy a variety of colors to get a wide range of vitamins and minerals.
  • Frozen Fruits and Vegetables: These are minimally processed and retain most of their nutrients. They are a convenient and affordable option for year-round access to produce.
  • Dried Fruit: Choose varieties with no added sugar or oil.

Fats, Nuts, and Seeds

  • Healthy Fats: Olive oil, avocado oil, and coconut oil are great for cooking and dressing.
  • Nuts and Seeds: Unsalted nuts like almonds, walnuts, and pecans, as well as seeds like chia, flax, and pumpkin, are perfect for snacking or adding to meals.
  • Nut Butters: Opt for varieties with a single ingredient—the nut itself—to avoid added sugars and oils.

Sample Meal Plan for a Non-UPF Diet

Meal Description
Breakfast Overnight oats with unsweetened Greek yogurt, fresh berries, and a sprinkle of nuts. Or, scrambled eggs with spinach and wholegrain toast.
Lunch A large salad with grilled chicken, chickpeas, and a simple olive oil and lemon dressing. Alternatively, a homemade lentil soup with whole-grain bread.
Dinner Baked salmon with roasted sweet potatoes and steamed broccoli. A hearty homemade spaghetti bolognese with whole wheat pasta and a fresh tomato sauce is another excellent option.
Snacks Apple slices with natural peanut butter, carrot sticks with homemade hummus, or a handful of unsalted nuts.

Practical Tips for Adopting a Non-UPF Diet

  • Cook at Home: Preparing meals from scratch gives you full control over the ingredients, allowing you to avoid hidden additives.
  • Read Labels: Scrutinize ingredient lists. If you see items you wouldn't use in your own kitchen, it's likely a UPF. A good rule of thumb is to look for products with a short, recognizable ingredient list.
  • Shop the Perimeter: Most whole, unprocessed foods like produce, meat, and dairy are located around the edge of the grocery store. The middle aisles often contain the most processed items.
  • Plan Ahead: Meal prepping can be a game-changer. Batch cook staple items like brown rice, lentils, or roasted vegetables to save time during busy weeks.
  • Make Gradual Swaps: Instead of overhauling your diet overnight, start with small, manageable changes. Swap sugary cereal for oatmeal, or packaged snacks for fruit and nuts. This approach makes the transition more sustainable.

Conclusion

Embracing a non-UPF diet is about returning to basics and appreciating food in its most natural state. By prioritizing whole and minimally processed options—fruits, vegetables, whole grains, lean proteins, and healthy fats—you can enjoy a more nutrient-dense diet that supports weight management, mood, and overall vitality. While it requires more home cooking and mindful shopping, the improved energy, better digestion, and reduced risk of chronic disease are well worth the effort. Starting with small, sustainable swaps is the most effective way to build a healthier eating pattern that lasts.
