India's food safety crisis: How contaminated and ultra-processed foods threaten public health

<p>Widespread food adulteration and ultra-processed diets are driving inflammation, antimicrobial resistance, and rising chronic diseases in India</p>

Nutritional scientist Prof Carlos Monteiro has said that ultra-processed foods (UPFs) are replacing healthy diets worldwide despite growing evidence of the risks they carry. He says that these ultra-processed foods must be sold with tobacco-style warnings.
