The Alarming Truth About Processed Foods: Are They Poisoning You?
Do you ever get worried about what you're putting into your body when you eat processed foods? I have been thinking about this, too, lately and it’s worrying.
You might also wonder, “What’s the big deal about a little convenience in my diet?” Well, let me tell you, the truth about processed foods is more alarming than you might think.
As we navigate our busy lives, reaching for that ready-made meal or snack is easy. But what if I told you that these ultra-processed foods could silently affect your health?
In this post, I’ll share insights from various studies highlighting the potential dangers of processed foods and how they might unexpectedly influence our health.
Why Worry About Ultra-Processed Foods?
Ultra-processed foods are a growing concern for health experts. One reason is fairly straightforward: these foods are often low in fiber and packed with calories, salt, added sugar, and fat—all of which are linked to poor health outcomes when consumed in excess.
However, back in 2009, researchers in Brazil suggested that the problem goes beyond just the nutrients. They proposed that the degree of processing itself plays a significant role in making these foods unhealthy.
Kevin Hall, a senior investigator at the National Institutes of Health (NIH), studies obesity and diabetes. When he first encountered this theory, he was skeptical.
"It struck me as a really odd way to think about nutrition science, because, after all, nutrients seem to be important for nutrition," says Hall.
To investigate further, Hall conducted a groundbreaking study in 2019. While most studies linking ultra-processed foods to negative health outcomes are observational and show only correlations, Hall designed a randomized controlled trial to examine the effects of an ultra-processed diet compared to one based on minimally processed foods.
He utilized the NOVA classification system, developed by Brazilian researchers, to categorize foods based on their level of processing. This system distinguishes between unprocessed or minimally processed foods, such as fresh fruits or vegetables; processed foods like canned tuna or smoked meats, which typically have just a few ingredients; and ultra-processed foods, which are made with highly industrialized formulations.
The results of Hall’s study were eye-opening: when participants ate an ultra-processed diet, they consumed about 500 more calories per day than those on a minimally processed diet. Over just two weeks, they gained an average of 2 pounds. Conversely, participants on the unprocessed diet tended to eat less and lost weight.
This research highlights why the extent of food processing might be just as important as nutrient content when it comes to health.
So the questions remains - why do we eat it? I wonder how the rise of this unhealthy foods even happened and why it’s still allowed.

The Rise of Processed Foods
Processed foods have become a staple in many diets around the world. These items, from frozen dinners to sugary snacks, are often marketed as convenient and tasty. However, many of these foods are ultra-processed, containing ingredients not typically found in a home kitchen, such as preservatives, artificial flavors, and colors. This shift towards ultra-processed foods is concerning because it causes various health issues. Let’s have a look at these health issues.
