Ultra-processed foods, such as packaged snacks, sweet drinks, and ready meals, have been linked to health problems in many studies. A recent research report adds a new detail: the body leaves measurable chemical traces of these foods in the blood.
What the research suggests
Researchers looked for patterns in blood samples that match the intake of ultra-processed foods. The findings support the idea that diet can be tracked through metabolism, not only through food diaries. This is still an emerging area, and more studies are needed to confirm the results.
What it means for you
- Ultra-processed foods are not all the same. Some packaged foods are simple, such as plain yogurt or frozen vegetables.
- The most useful habit is to eat more whole foods: vegetables, fruit, legumes, nuts, and eggs.
- Read labels. A long ingredient list with many additives is a good sign that a food is highly processed.
Simple swaps
- Replace sweet cereal with oats and fruit.
- Replace packaged chips with roasted chickpeas or nuts.
- Replace sugary drinks with water, sparkling water, or unsweetened tea.
You do not need to remove every processed food. Start with the ones you eat most often.
