But the number of capillaries decreases with age so that the nutrition delivered to the heart also decreases, making the heart beat weak. Ignoring this condition can cause serious heart diseases.
But recently a substance to stop the aging of heart has turned out.
The substance is GLP-1.
According to a research published on The New England Journal of Medicine, people who took GLP-1 for 3 and a half years had 22% less development of heart diseases that people who didn’t. Therefore, GLP-1 can be expected to prevent the aging of the heart and keep vigorous heartbeat.
GLP-1 is a hormone secreted from the small intestine.
The keys to increase the secretion of GLP-1 are:
(1)What to eat
(2)When to eat
(1) What to eat
The important things of what you eat are foods containing proper amount of sugar and insoluble dietary fiber, which stimulates the small intestine and promotes the secretion of GLP-1.
The foods containing proper amount to sugar and insoluble dietary fiber are root vegetables such as carrot, burdock, potato, sweet potato, yam, etc. Different from carbohydrate, the sugar contained in root vegetables is appropriate to stimulate the small intestine and root vegetables are rich in insoluble dietary fiber as well (Fig. 1).
(2) When to eat
The important thing of when to eat is eating 3 meals a day at the same time. This makes the small intestine stimulated at the same time, leading to more secretion of GLP-1.
GLP-1 originally got attention as a hormone lowering blood sugar and is used as the medication for diabetes. But it has turned out that GLP-1 protects the blood vessels of the heart as well.
2 functions of GLP-1
(1) It was said that lost capillaries wouldn’t increase again, but according to various researches, GLP-1 can increase capillaries.
(2) It was also said that plaque, which rapture causes heart attack, created once in the blood vessel wouldn’t be removed, but GLP-1 can decrease plaque, prevent the hardening of the arteries and protect the function of the heart.
Eating root vegetables at the same time 3 times a day stimulates the small intestine regularly and activates the secretion of GLP-1. It seems a little difficult.
But there is a food that is easy to take with you and is expected to secrete GLP-1.
Almond is the food expected to secrete GLP-1.
Nuts are rich in insoluble dietary fiber and almond has a higher content of insoluble dietary fiber than other nuts and root vegetables.
So it is recommended to eat root vegetables 3 times a day at the same time as often as possible and to take almonds when you can’t eat root vegetables at the regular time.
