Is there any scientific basis for drinking coffee appropriately? Is there any scientific basis for this? Japanese Diabetes Specialist, Ichiyuki Yui explained the relationship between coffee and blood sugar levels.

Only type 1 diabetes patients need to pay attention to the impact of coffee

After drinking coffee, the caffeine in the coffee will stimulate the sympathetic nerves, thereby weakening the effect of insulin, resulting in an increase in blood sugar. However, intestinal intraocularis can regulate blood sugar, so even drinking coffee will not cause problems.

In terms of diabetes patients, even if they drink coffee, they usually do not affect the degree of blood sugar control to the point of virility. However, for patients with type 1 diabetes, due to the lack of insulin secretion in the body, some patients may increase their blood sugar levels due to coffee, so special attention is needed.

When the body's sensitivity to insulin is reduced, making its effect unable to be fully utilized, this state is called "insulin impedance". Research data shows that people who drink coffee are less likely to develop diabetes, which may be related to the polyphenols contained in coffee that help improve insulin impedance.

In summary, except for patients with type 1 diabetes, drinking coffee will not cause blood sugar levels to rise to a level that affects health. However, if you worry about blood sugar levels, it is recommended to avoid drinking coffee in the morning. This is because caffeine stimulates the sympathetic nerves and weakens the effect of insulin, and morning itself is a period of active time. Drinking coffee at this time may further reduce the effect of insulin.

Type 2 diabetes patients and the "high-risk groups of diabetes" in the early stages of diabetes should also be noted that although there are no special problems when drinking coffee, if the coffee is added with ingredients such as sugar or milk, it may increase sugar intake, so it should be paid attention to.

According to standards in Europe, the United States and Canada, it is recommended that daily intake of less than 400 mg (about 3 cups of coffee) will not increase health risks. A recent study published in the scientific journal "Ageing Research Review" pointed out that drinking about 3 cups of coffee a day can extend your life by about 1.8 years, and regular coffee consumption is related to the extension of healthy life (referring to the time of living without major illness).
