Ultra-processed foods are foods that have undergone extensive industrial processing, adding artificial ingredients, preservatives, sugars, fats, and salt. These foods are convenient and tasty, but they can also harm your health in many ways. In this article, we will explain what ultra-processed foods are, why they are bad for you, and how to avoid them.
What are Ultra-Processed Foods?
According to the NOVA classification, a system that categorizes foods based on the degree and purpose of processing, ultra-processed foods are those that are made from substances extracted or derived from food, or synthesized in laboratories, and that contain little or no whole foods. Ultra-processed foods are designed to be highly palatable, durable, and profitable, but they also have low nutritional quality and high energy density.
Some examples of ultra-processed foods are:
- Soft drinks, energy drinks, and fruit juices with added sugar
- Cookies, cakes, pastries, and ice cream
- Chips, crackers, and popcorn
- Instant noodles, soups, and sauces
- Frozen meals, pizzas, and burgers
- Hot dogs, sausages, and nuggets
- Breakfast cereals, bars, and spreads

Why are Ultra-Processed Foods Bad for You?
Ultra-processed foods are bad for you for several reasons. They can:
- Increase your risk of obesity, diabetes, and cardiovascular diseases, as they contain high amounts of added sugars, unhealthy fats, and salt, which can raise your blood pressure, cholesterol, and blood sugar levels, and cause inflammation and oxidative stress.
- Increase your risk of cancer, as they contain artificial additives, preservatives, and colorings, which can damage your DNA and cause mutations and tumors.
- Affect your gut health, as they contain low amounts of fiber, probiotics, and antioxidants, which can disrupt your microbiome and impair your digestion and immunity.
- Affect your brain health, as they contain low amounts of omega-3 fatty acids, vitamins, and minerals, which can affect your mood, memory, and cognition.
- Affect your appetite and satiety, as they contain high amounts of refined carbohydrates, which can spike your insulin and blood sugar levels, and cause cravings and overeating.
How to Avoid Ultra-Processed Foods?
The best way to avoid ultra-processed foods is to eat more whole foods, such as fruits, vegetables, whole grains, legumes, nuts, seeds, lean proteins, and healthy fats. These foods are rich in nutrients, fiber, antioxidants, and phytochemicals, which can support your health and prevent diseases. Some tips to eat more whole foods are:
- Plan your meals and snacks ahead of time, and prepare them at home as much as possible.
- Read the labels of the foods you buy, and avoid those that have a long list of ingredients, especially those that you cannot pronounce or recognize.
- Choose fresh, frozen, or canned foods that have no added sugar, salt, or oil, and that are minimally processed.
- Drink water, tea, or coffee instead of sugary drinks, and add natural sweeteners, such as honey, maple syrup, or stevia, if needed.
- Enjoy treats occasionally, but limit your portion size and frequency, and opt for homemade or natural alternatives, such as dark chocolate, dried fruits, or nuts.
