Consumption of ultra-processed industrial foods is linked to an increased risk of type 2 diabetes, according to a study published in February 2023 in the journal Diabetes Care.
Some of these foods seem to contribute more to the increased risk.
Jean-Philippe Drouin-Chartier of Laval University (Quebec) and his colleagues analyzed data from three large American surveys in which some 198,600 participants responded, every 2 to 4 years for 30 years, to questionnaires on their diet.
The foods consumed were subdivided into four categories according to their degree of processing, ranging from minimally or unprocessed to ultra-processed.
« Ultra-processed foods are defined as industrial formulations made largely or entirely with substances extracted from foods, often chemically modified, and in which there are additives to accentuate flavors or extend shelf life. In the United States and Canada, these foods account for about one-third of the weight of food consumed daily by the population.
“says Professor Drouin-Chartier. (What are ultra-processed foods? The NOVA classification of foods into 4 groups)
A direct association between the consumption of ultra-processed foods and the risk of diabetes has been observed:
- every 1% increase in the consumption of ultra-processed foods translates to a slightly more than 1% increase in the risk of type 2 diabetes;
- the risk of people in the top quintile of consumption is 56% higher than that of people in the bottom quintile.
Combining these data with those from four European studies that looked at the same question, making up a cohort of more than 415,500 participants, led to similar conclusions. “The sample size and the strength of the relationship we observed between the two variables suggest causation
“says the researcher.
Some ultra-processed foods seemed to contribute more to the increased risk of diabetes:
«
This is the case for white breads, sauces, spreads and condiments, sugary drinks, “diet” drinks, cold meats and deli meats and ready-to-heat meals. We can therefore think that by reducing the consumption of these foods, we reduce the risk of developing type 2 diabetes.».
The level of food processing does not translate perfectly to their health value, recognizes the researcher, but it is a meaningful indicator that allows simple messages to be sent to the population. “We must consume as little as possible, he summarizes. To support metabolic health, eat fresh or minimally processed foods.
