According to a follow-up survey of 264 elderlies conducted for 10 years in US, people who had wrinkles in their earlobe had 2 times higher heart diseases development rate, compared to people who didn’t have.
Since the earlobe originally has a low number of the artery running around, once hardening of the artery happens, that promotes poor nutrition, making the wrinkles in the earlobe deep (Fig. 1).
It is thought that the degree of hardening of the artery in the earlobe is almost the same as the one in the heart. That is why the wrinkles in the earlobe act as a barometer of the hardening of the artery in the heart.

3. A hormone that stops the aging of the heart
A hormone that rejuvenates the artery of the heart is GLP-1. The cause of stroke is plaque accumulated in the artery of the heart. GLP-1 removes plaque and rejuvenates the artery.
GLP-1 is secreted more when the number of chewing increases.
So hard food is good to increase the secretion of GLP-1 like dried squid.
4. There is a hormone that protects the heart.
Recent researches have shown that the hormone that strengthens the heart is omentin.
In a recent research, when they cause the heart of a normal mouse to have stroke, the muscle of the heart becomes necrotic.
But in the case of the mouse that secretes a lot of omentin, the area that becomes necrotic is much smaller (Fig. 2).
That means, even though the blood flow to the heart muscle stops, the heart keeps working.
It has tuned out that intake of olive oil tends to increase omentin.
Omentin is also secreted from visceral fat, but it is not secreted from the visceral fat of overweight individual. Olive oil is thought to have the effect to suppress obesity.
