Is Ultra-Processed Food Worthless?
Ultra-processed food (UPF) has been in the news again: researchers have found a relationship between plant-based UPF and cardiovascular disease (CVD) and mortality. Health news writers were brimming with opinions on what the study meant. The comment that got my attention was that UPF manufacturing destroyed good nutrients found in plant foods to the point that there was no benefit to eating them. For example, store-bought cereals and cookies are worthless no matter how much fruit or nuts are added.
Is that true?
Let’s begin by looking at the study. Researchers used data from the UK Biobank database. They selected only the participants who completed at least two 24-hour dietary recalls—118,397 subjects. All participants were part of the healthcare system in the UK, so the researchers were able to collect diagnostic and mortality data from electronic medical records.
Researchers divided the dietary data into four groups:
- Non-UPF plant-sourced foods (fresh grapes or canned corn)
- UPF plant-sourced foods (corn chips or vegan burgers)
- Non-UPF animal-sourced foods (ground beef or canned tuna)
- UPF animal-sourced foods (chicken nuggets or ice cream)
The two main findings were that the more UPF plant-sourced foods were eaten, the higher the risk of CVD and CVD mortality; second, the increase of non-UPF plant-sourced foods reduced the risk of CVD and mortality. I think those results were to be expected. In Saturday’s Memo, we’ll take a closer look at whether the expert diatribes about negating the benefits of UPF-plant-sourced foods were warranted.
