Ultra-processed foods (UPFs) often get a bad rap, and for good reason: many are high in unhealthy fats, added sugars, and preservatives. However, life isn’t always about picture-perfect meal prep; sometimes a quick, easy option is necessary. Is there a place for these foods within your diet?
What Exactly Are UPFs, and Why Do They Get a Bad Rep?
Ultra-processed foods refer to food and drink products that undergo significant industrial processes and contain ingredients not typically used in home cooking. These ingredients often include preservatives, sweeteners, emulsifiers, and other additives to enhance flavour, texture, or shelf life.
As we have previously discussed, research on UPFs reveals significant health concerns, particularly when these foods dominate a diet.
UPFs are said to harm health due to their high levels of added sugars, unhealthy fats, and artificial additives, which disrupt the body’s natural processes. They are engineered for taste, leading to overconsumption and often containing fewer essential nutrients than whole foods.
What Are The Benefits of Food Processing?
As emerging research highlights links between intake of UPFs and negative health outcomes, intake should be considered. However, it isn’t as black and white as it seems. Not all UPFs are created equal. Some offer added nutrients or act as a quick source of energy without tipping the scale towards poor health outcomes. “It’s not about demonising food but understanding its role,” says Dr. Kevin Hall, a leading researcher in nutrition and metabolism.
The convenience of processed foods is a major advantage, especially in today’s fast-paced world, where many rely on quick options to ensure they and their families are well-fed.
Aside from the convenience aspect, some of the benefits include:
- Prolonged shelf-life
The primary purpose of food processing is to prolong shelf life through methods like pasteurisation, sterilisation, fermentation, drying, freezing, canning, and the use of specific additives.
This is helpful for reducing food waste, improving food safety as food is less likely to harbour bacteria and increasing food availability due to transporting and storing food more easily.
- Increased food safety
Another key purpose of food processing is to enhance food safety.
Food processing improves safety by reducing foodborne risks through methods like pasteurisation, sterilisation, and freezing. These techniques kill bacteria and extend shelf life.
- Enhanced nutrient content
Processed foods can sometimes be more nutritious due to fortification, like plant-based milks with added calcium or iron-enriched cereals.
Techniques such as fermentation can enhance nutrient availability, while freezing preserves vitamins like C.
Processing also increases access to diverse foods not locally available, offering nutritional variety, though some methods, like heat treatment, may reduce certain nutrients.
When are UPFs Practical (and Even Beneficial)?
There are times when UPFs may be a practical option:
- Filling Nutritional Gaps
Fortified UPFs like plant-based milks with calcium or cereals enriched with iron provide essential nutrients that may be lacking in whole-food diets. - Quick Recovery for Athletes
Protein shakes and energy bars offer convenient post-workout nutrition, aiding muscle repair and replenishment. - During Emergencies
Shelf-stable UPFs, such as tinned goods or meal replacement shakes, can be vital during natural disasters or when fresh food isn’t accessible. - For Food Accessibility
In areas with limited access to fresh produce, frozen or fortified UPFs ensure people can still get essential nutrients. - Time-Saving for Busy Lifestyles
Ready-to-eat or easily prepared UPFs like wholegrain bread or pre-packaged salads help individuals maintain balanced diets on hectic days.
How To Choose UPFs more wisely
Navigating supermarket shelves can be overwhelming. Here are a few tips for identifying better options:
- Scan the Ingredients List: Look for short, recognisable ingredient lists. Avoid items with excessive artificial additives, hydrogenated oils, or high-fructose corn syrup. Prioritise UPFs made with whole-food ingredients.
- Prioritise Fortification: Some UPFs are fortified with essential vitamins and minerals, making them a practical choice.
- Keep Sugar and Sodium in Check: Aim for <5g of sugar per serving and moderate sodium levels (less than 400mg per serving).
Striking a Balance: Real Food First
So, is there a place for UPFs in your diet? Yes, potentially!
Not all UPFs are nutritional villains and some may be helpful in certain instances. However, while ‘clean’ UPFs can be helpful, it’s crucial to remember they’re not a substitute for whole, minimally processed foods. Fresh fruits, vegetables, lean proteins, and whole grains should form the foundation of your diet.
Use UPFs strategically—when time is tight, when you need a nutritional boost, or when you simply can’t prepare from scratch.
As nutritionist Marion Nestle aptly puts it, “Eat real food, not too much, mostly plants—but don’t stress about occasional shortcuts.”
