🍦 A surprising correlation between ice cream and reduced diabetes

Here is a rather astonishing observation: higher ice cream consumption seems linked to a lower risk of developing type 2 diabetes. This finding goes against usual nutritional advice, as this dessert is typically singled out for its sugar and saturated fat content.

By analyzing data from large groups, such as healthcare professionals in the United States, researchers noticed that regular ice cream intake was associated with a less frequent onset of this metabolic disease. Several studies have since reproduced this association, which has naturally captured the interest of scientists.


As early as the 2000s, clues appeared in studies on dairy products. Examining dietary habits within cardiovascular disease research showed that dairy desserts, especially ice cream, were linked to a notable decrease in insulin resistance. This effect was clearer than with standard milk, indicating something unusual.

At the same time, other studies confirmed the benefits of yogurt. A review published in BMC Medicine reported that a daily serving of yogurt lowered the risk of type 2 diabetes by 18%. This relationship is more easily explained by the presence of probiotics and the fermentation process, known for their positive influence on the gut and metabolism.

To explain this signal specific to ice cream, various leads are being examined. One of them, called reverse causality, suggests that healthy individuals eat more ice cream, while those who perceive early symptoms might reduce their consumption, which would skew the statistics. Furthermore, reporting errors in dietary questionnaires, where foods considered unhealthy are often underestimated, could also influence the results.

Some biological mechanisms are also being considered. The glycemic index of ice cream remains moderate due to its fat and protein content. Additionally, the membrane surrounding the milk fat globules, which remains intact in ice cream, could exert positive effects on metabolism.

Caution is still advised: this data does not turn ice cream into a health food, but encourages a better understanding of how dairy products interact with diabetes risk.

The milk fat globule membrane: a little-known biological structure

This natural membrane surrounds fat droplets in dairy products. Composed of phospholipids and proteins, it plays a role in the digestion and assimilation of nutrients. During processing, such as butter making, this structure is often destroyed, altering its properties.

In ice cream, manufacturing methods generally allow its preservation. Preliminary work suggests this integrity could have favorable consequences for metabolism, for example by modulating inflammation or affecting gut health. These processes could partly explain the observations made with ice cream.

Research on this topic is just beginning, and scientists are studying how different forms of dairy fats act on the body. A better understanding of these interactions could lead to more nuanced nutritional recommendations, considering not just the quantity of fats, but also their structure and metabolic consequences.
