A recent study found that consuming more than six cups of coffee daily may increase the risk of Alzheimer’s disease and dementia, but the risks differ depending on gender and type of coffee.
- According to a study, the correlation between the risks of cognitive decline and coffee varies according to the type of preparation and the gender of the person.
- Researchers found that having more than eight cups of boiled coffee daily was associated with an increased risk of dementia in women, but not in men.
- On average, the risk of Alzheimer’s disease is increased from six or more cups of boiled coffee.
Because it is rich in antioxidants, coffee is believed to have interesting anti-inflammatory properties. However, it would seem that good things should not be abused, as a study published in nutrient May 25, 2023. Researchers show that black nectar may increase the risk of dementia or Alzheimer’s disease depending on the gender of the drinker or the method of preparation (boiled, strained) drink.
Coffee : the type of preparation affects the risk of dementia
By analyzing the coffee drinking habits of 8,758 people from Over 40 years followed over an average period of 22 years, Norwegian researchers found that the impact of coffee on cognitive health depends on the type of coffee. For example, a daily consumption of six or more cups of boiled coffee (unfiltered drink such as Turkish coffee or prepared with a French press) may increase the risk of dementia and Alzheimer’s disease. This negative association was observed only from more than eight cups for filtered coffee.
Additionally, drinking between four and seven cups of boiled coffee a day was associated with an increased risk of mild cognitive impairment. (MCI)which are often considered a precursor to Alzheimer’s disease and other forms of dementia. However, no significant correlation has been established between the consumption of other types of coffee and the risk of MCI and Alzheimer’s disease.
Dementia : coffee more harmful for women
In addition, the study showed that coffee also had different effects depending on the gender of the amateur. Indeed, if the daily consumption of four to five standard cups of coffee was associated with a reduced risk of dementia in men, women did not present a reduction in risk with this type of drink.
Additionally, the researchers found that having more than eight cups of boiled coffee daily was associated with a higher risk of dementia in women, but not in men.
But, sex is not the only element that can enter into the equation. Indeed, the daily consumption of six to seven cups of boiled coffee was associated with an increased risk of dementia in non-carriers of the gene. ApoE4but not in carriers ofApoE4.
“Given that coffee and tea are among the most widely consumed beverages in the world and that cognitive decline is common in the elderly, the minor potential health benefits or risks associated with the consumption of coffee and tea could have a significant effect on public health. Long-term intervention studies are needed to unravel the possible relationship between coffee consumption, dementia risk, type of coffee, gender, and carrier status.ApoE4“conclude the scientists.
