Look at the evidence to dispel the myth: drinking coffee alone will stimulate blood sugar concussion?

Recently, many friends have posted a film to ask the dietitian: "dietitian, does drinking coffee alone really affect the change of blood sugar?" Drinking coffee equals eating sugar will shake blood sugar? (black question mark face) ) "

As it was already too much to disturb, I spent a little time (as a result, several hours). Looking for three pieces of empirical data, the results showed that for a single intake of caffeine, it did increase the concentration of fatty acids in blood, but there was no significant change in blood glucose and insulin.

The following picture shows that in experiment (a) 10 healthy male adults in Taiwan were taken one hour before retraining:

1. Caffeine (CAF)

two。 Carbohydrates + caffeine (CHO+CAF),

3. Carbohydrate (CHO),

4. Drink a water placebo (CON).

The experiment was divided into 4 times, and the interval of each experiment was 7 days.

Caffeine dose: 6mg/ per kilogram of body weight.

Carbohydrate dose: 5g/ per kilogram of body weight.

The results were compared between the concentration of blood glucose and the effect of coffee. Yang Chenghua / courtesy of

Blood samples were drawn at 0, 15 and 30 minutes before ingestion, 60 minutes after ingestion, before retraining and at the end of retraining.

The results of blood test showed that when caffeine was ingested alone, there was no significant change in blood glucose or insulin during the period of 1 hour before exercise.

The same results were seen in two other studies (b and c), whether obese or normal, young or older women.

One of the articles also observed that there was no significant change 3 hours after intake.

Three human experiments at home and abroad have shown that drinking coffee alone will not increase blood sugar or insulin for normal people. (the evidence speaks, the case is closed! )

So.

Don't listen to the baseless words of movies circulated on the Internet.

If you have any questions, please remember to find a real professional instead of following others. There are a lot of eyebrow corners hidden in the details that professionals can help you find, not because there is a certain substance, so it must be this material that causes a certain result, which is a very problematic superficial interpretation.
