In the context of modern dietary habits, ultra-processed foods (UPFs) are now a constant presence. Their convenience and low cost make them a popular choice, but at a significant cost to health. A recent study, in fact, has highlighted a significant link between the consumption of these foods and intermediate cardiometabolic risk markers, such as lipoprotein profiles, which are precursors to chronic conditions like diabetes and cardiovascular diseases.
What are Ultra-Processed Foods and Why Do They Pose a Problem?
Ultra-processed foods are industrial products that undergo multiple transformations and contain artificial ingredients such as preservatives, flavourings and additives. Among the most common examples are:
- Packaged snacks
- Sugary drinks
- Frozen ready meals
- Sugary breakfast cereals
- Fast food
Several studies have already associated a diet rich in UPFDs with chronic diseases. This specific study, however, focuses on the impact of such foods on intermediate risk markers, particularly lipoproteins, which are key indicators of cardiovascular health.
The Study: Results and Implications
Researchers analysed 1,986 individuals aged between 40 and 70 years. Using nuclear magnetic resonance spectroscopy, the size and concentrations of lipoproteins, which carry cholesterol in the blood, were assessed. Here are the main findings:
- Reduction of HDL cholesterol (“good”) and large LDL lipoproteins.
- Increase in small LDL, the most dangerous for arterial health.
- Reduction of LDL and HDL particle size, linked to inflammatory processes and atherosclerosis.
- Increase in medium-sized VLDL, linked to insulin resistance and fatty liver.
Increased consumption of UPFDs worsens the lipid profile, increasing the risk of:
- Cardiovascular diseases, through the accumulation of atherosclerotic plaques and inflammation.
- Type 2 diabetes, favoured by insulin resistance and increased VLDL lipoproteins.
Small LDL particles easily penetrate arterial walls, contributing to vascular obstruction. Simultaneously, the accumulation of liver fat is a warning sign for metabolic disorders and future complications.
Here are some strategies for limiting the introduction of UPFD into the daily diet:
- Prefer fresh, natural foods, such as fruit, vegetables, whole grains, and legumes.
- Preparing meals at home to avoid unnecessary additives and preservatives.
- Check the labelsChoose products with few artificial ingredients and no added sugars.
- Replace sugary drinks with water, herbal teas or unsweetened tea.
The study offers an additional reason to reduce consumption of ultra-processed foods. Their convenience does not compensate for the serious health risks they pose. Adopting a diet based on fresh, minimally processed foods not only improves overall wellbeing but is also an investment in preventing cardiovascular and metabolic diseases.
Making conscious choices at the table means taking care of your health, increasing the chances of a long and fit life.
