Ultra-processed foods linked to cancer
Thursday February 15 2018
Examples include mass-produced breads and cakes, snacks and sweets, fizzy drinks, and ready meals.
Researchers in France studied the diets of more than 100,000 people for 7 years.
They found small increases in the overall rate of cancer and breast cancer after the menopause in those who had the highest proportion of ultra-processed food in their diet.
But because of the wide range of foods included in the ultra-processed category, it's difficult to establish which specific foods might be responsible for the increased cancer risk, and why.
The increased risk could be caused by eating more high-sugar, high-fat processed food.
