Fighting Alzheimer’s Disease
The antioxidants in coffee are said to protect us from Alzheimer’s disease. According to a study published in the journal Pubmed, consuming 3 to 5 cups of coffee could reduce your risk of developing the disease by 20%.
The researchers concluded: “Coffee consumption may be associated with a lower risk of dementia. This can be mediated through caffeine and / or other mechanisms such as antioxidant capacity and increased insulin sensitivity. This finding could open up opportunities for prevention or delay the onset of dementia. “”
Regulation of intestinal transit

However, a second study published in the journal Pubmed warns of the occurrence of gastric reflux with excessive consumption. Even if it confirms its effect on intestinal transit: “Coffee promotes gastroesophageal reflux, but is not associated with dyspepsia. Coffee stimulates the contraction of the gallbladder and motor activity of the large intestine. “”

Fight against pain
Migraineurs know that drinking strong coffee relieves pain! However, scientists cannot pinpoint the cause of these reliefs. As an American study explains: There is no doubt that the daily and sporadic consumption of caffeine through food has significant biological effects on the nervous system.
