A new study shows that eating a lot of ultra-processed foods may increase the risk of depression. The research, published in a medical journal, adds to evidence that what we eat can affect how we feel mentally.
More Processed Foods, More Risk
Researchers followed adults over several years. They found that people who ate the most ultra-processed foods were more likely to feel depressed than those who ate more natural, whole foods. This link remained even after considering factors like age, exercise, income, and general diet.

What Are Ultra-Processed Foods?
These are factory-made foods with little to no fresh ingredients. They often contain added sugars, unhealthy fats, and artificial chemicals. Common examples include chips, cookies, instant noodles, sugary cereals, soft drinks, frozen meals, and processed meats like hot dogs and nuggets.
How They May Affect Mental Health
Experts say these foods lack key nutrients and may harm brain chemicals like serotonin, which helps regulate mood. Nutritionist Dr. Priya Nair explained that processed foods may increase inflammation and throw off the body’s natural balance.
Psychiatrist Dr. Sameer Khanna added that poor eating habits, especially diets full of processed foods, are linked to higher rates of depression and anxiety.

The Gut-Brain Link
One possible reason is the gut-brain connection. A poor diet can disrupt gut bacteria, reduce nutrient absorption, cause inflammation, and impact brain health. High sugar levels in these foods can also cause mood swings and tiredness.
What You Can Do
Ultra-processed foods make up a large part of many people’s daily diets, especially in cities. Experts recommend eating more fresh fruits, vegetables, whole grains, lean protein, and healthy fats to support mental and physical health.
More Research Needed
The study doesn’t prove that ultra-processed foods cause depression, but it shows a strong connection. Researchers hope this will lead to more studies and better food guidelines in the future.
