Research shows that drinking coffee in moderation is good for your health

Researchers at Kuopio University in Finland and the Karolinska Association in Stockholm, Sweden, said in a recent press release that assuming high global coffee consumption, the results may have important implications for preventing or delaying the onset of dementia / Alzheimer's disease. The findings of this study need to be confirmed by other studies, but it opens up dietary intervention that may change the risk of dementia / Alzheimer's disease and may be helpful in the latest treatments for these diseases.

Drinking the right amount of coffee at a young age can reduce the risk of dementia and Alzheimer's disease in old age, according to a new study. Researchers from Finland and Sweden examined the records of 1409 participants' coffee drinking habits in middle age.

In the Journal of Alzheimer's Disease (JournalofAlzheimersDisease) earlier this year, researchers said that people who drank three to five cups of coffee a day in middle age were less likely to develop dementia and Alzheimer's disease over a follow-up period of more than 20 years.

Those who drank the most coffee every day had the highest rates of total cholesterol and smoking in middle age, while those who drank less coffee had the highest risk of dementia and Alzheimer's disease and the highest depression index in old age. Kivipelto said their aim was to study the association between tea and coffee drinking in middle age and the risk of dementia and Alzheimer's disease later in life, because the long-term effects of caffeine on the central nervous system are unknown, and the pathological processes that lead to Alzheimer's disease began decades before the disease was clinically confirmed.

In the study, participants were asked how much coffee they drank in 1972, 1977, 1982 and 1987 when they were middle-aged (average age 50). They were then divided into three groups: coffee drinkers who drank a small amount of coffee every day (zero to two cups), coffee drinkers (three to five cups), and coffee drinkers (more than five cups a day).

Among the participants, 15.9% were coffee drinkers, 45.6% were moderate coffee drinkers, and 38.5% were coffee drinkers. On average, 1409 people aged 65 to 79 were tested again after 21 years. A total of 61 people were classified as dementia and 48 had Alzheimer's disease.

The results showed that coffee drinkers had a lower risk of dementia and Alzheimer's disease in middle age than those who drank little or no coffee, and those who drank moderate amounts of coffee had the lowest risk, the researchers pointed out. People who drink moderate amounts of coffee have a 65 to 70 percent lower risk of dementia and 62 to 64 percent less risk of Alzheimer's disease than those who drink little or no coffee.

The researchers pointed out that drinking coffee can improve cognitive performance, caffeine can reduce the risk of Parkinson's disease, and it is not clear how much coffee needs to prevent dementia, but drinking coffee is also associated with reducing the risk of type 2 diabetes. Type 2 diabetes is a risk factor for dementia, and the researchers speculate that its effect may be related to the antioxidant capacity of coffee in the blood.

Studies have also shown that tea drinking has nothing to do with reducing the risk of dementia or Alzheimer's disease.
