In response to the question: "Does the speed at which you eat affect your health?" Dr. Sarah Berry answered that eating quickly is not good and can affect many aspects of health. Dr. Sarah Berry said that many studies have shown that eating quickly increases the risk of diabetes, according to the Mirror .

Evidence from research

Several epidemiological studies have found a significant association between fast eating and the onset of diabetes, according to the US National Library of Medicine Pubmed.

Two large Japanese studies including 2,050 middle-aged men, followed for seven years, concluded that eating speed was significantly associated with the risk of developing diabetes, but depending on body weight.

A similar Japanese study investigated the association between eating speed and insulin resistance in 3,465 middle-aged men and women. The results showed that eating quickly increased insulin resistance.

Another large Japanese study, using annual population health examination data, investigated the association between eating speed and new onset of diabetes among 197,825 participants, followed for 3 years.

The results also found that fast eating significantly increased the risk of diabetes.

A case-control study conducted in Lithuania that included 702 participants, reported that the risk of type 2 diabetes was 2-fold increased in people who ate faster, according to Pubmed.

In addition, many studies have also shown that eating fast increases the risk of metabolic syndrome - which is related to diabetes.

Dr Berry also referred to a 2017 study, conducted by a cardiologist from Hiroshima University in Japan, which found that eating fast nearly doubled the risk of metabolic syndrome, according to Mirror .

Several other studies, notably a Japanese study published in the Journal of the American Heart Association, which included 1,083 participants and was followed for five years, have shown a significantly higher risk of developing metabolic syndrome in fast eaters, according to Pubmed .

However, there is no research to show how long to eat to prevent the risk of diabetes, so more research is needed to learn more about this issue.
