‘ULTRA-PROCESSED FOODS’ – ANOTHER RED HERRING?
It’s nothing new to demonise food processing. As a student of food science and nutrition, I read on one hand that food processing was necessary, helping to preserve foods and prevent food wastage, while on the other hand, it was a necessary evil that stripped foods of important nutrients.

In whole or partially cracked cereal grains, for example, the starch is physically confined which slows its digestion and lowers the GI. Good examples are most (but not all) cereal grains and “wholegrain” …
WHEN ‘ULTRA-PROCESSED FOODS’ AREN’T BAD: BREADS AND BREAKFAST CEREALS
The use of the term ‘ultra-processed foods’ was born in research but has reached the wider world.
