‘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. Milling of wheat grains into white…

‘ULTRA-PROCESSED FOODS’ AND HEALTH OUTCOMES: MORE RESEARCH NEEDED
A group of Australian and Spanish researchers have published a systematic review and meta-analysis looking at the association between consumption of ‘ultra-processed foods’ and various health outcomes. The review included 43 observational studies and found that consumption of ‘ultra-processed foods’ was associated with an increased risk of overweight, obesity, abdominal obesity, all-cause mortality, metabolic syndrome…

‘ULTRA-PROCESSED FOODS’ – PROBLEMATIC FOODS OR PACKAGING?
Prospective cohort studies have found associations with high consumption of ‘ultra-processed foods’ and increased risk of overweight, obesity, high blood pressure, high cholesterol, breast cancer, cardiovascular diseases (e.g., heart disease and stroke) and all-causes of death (mortality). Authors of these studies have suggested many potential reasons for these associations: Compared to minimally-processed foods and drinks,…

GI AND THE NOVA CLASSIFICATION SYSTEM
You might have heard low GI foods being described as generally less processed or refined, and closer in form to “whole” foods. 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. The NOVA classification system classifies foods into four groups: unprocessed or minimally processed foods (fruit, vegetables, meat, eggs) processed culinary ingredients (oils, butter, salt, sugar) processed foods (canned or bottled vegetables, legumes, fruit, fish, pickled vegetables, smoked and…
