Ultra-processed foods are a major public health concern for their potential adverse effects on health. Now a study by the Department of Epidemiology and Prevention of the I.R.C.C.S. Neuromed in Pozzilli (Italy) explores the health effects of a large dietary share of ultra-processed food on people already suffering from cardiovascular diseases. The findings indicate a higher risk of a second heart attack (or stroke), this time fatal. Moreover, another observation emerges from this study: Even in people generally following the Mediterranean diet, but consuming too many ultra-processed foods, health risks are higher.
