The benefits of eating slowly: Diabetes
Eating fast is very significantly involved in the risk of developing type 2 diabetes.
Eating fast increases the risk of type 2 diabetes
Since the 2010s, the correlation between type 2 diabetes and feeding speed (eat fast / eat slowly) is demonstrated by numerous studies * (1, 2, 5), some of them with significant statistical population of several thousand people.
A study * (2) with 700 people even figures the probable risk increased by 2.5 of triggering type 2 diabetes for a fast eater compared to a slow eater.
A study * (4) measures an increase in glycated hemoglogin correlated with that of feeding rate.
A study * (3) with fast eaters measures a decrease in the hormone GLP 1 which delays the rate of glucose absorption at the level of the intestinal epithelium and therefore an effect of increasing glycemic oscillations post -prandiales. Namely that GLP 1 is commonly prescribed in a similar form, by subcutaneous injection, by the names of Byetta or Victoza in the context of the treatment of type 2 diabetes in addition to oral anti-diabetics
At least two explanations can be advanced to explain these very significant results.
Fatigue of the pancreas
A medium-term effect of pancreatic fatigue: The insulin secreted by the pancreas lowers the concentration of sugar in the blood. When there is a higher sugar peak in the blood, which may be due to too fast ingurgitation, the pancreas is more heavily used to secrete insulin. Over time, the pancreas may show signs of fatigue and the risk of type 2 diabetes increases.
Action of chewing
As demonstrated by the studies (6,7) a higher masticatory cycle has the effect of facilitating the absorption of glucose and / or lowering the glycemic index of foods.
Chewing strong - Glycemic index of rice eaten with sticks: 68
Chewing less strong - Glycemic index of rice eaten with a spoon: 81
The present study suggests that eating rice with different tools, depending on chewing time and amount of food ingested per bite, changes the Glycemic Index (GI) of the ingested rice.

Links to international studies
- Higher masticatory performance and slow eating prevent the occurrence of diabetes (Japan, 2013, 6927 adults)
- More than two‐fold increased risk of type 2 diabetes was determined for subjects eating faster vs. subjects eating slower. (Lituania, 2013, 702 personnes)
- Slow feeding leads to higher concentrations of GLP1 in obese adolescents (Italy, 2013, 18 teens)
- HbA(1c) rose significantly as eating rate increased (Japan, 2013, 7 275 adults > 40 ans)
- Eating speed was associated with the incidence of diabetes (Japan, 2012, 2 050 men adults)
- A higher number of mastication cycles before ingestion can have beneficial effects on the satiety and facilitates the absorption of glucose. (USA, 2015, 21 hommes)
- Eating rice with different mastication times modifies the glycemic index of rice. (Turkey, 2015, 11 adults)
