Don’t be afraid of caffeine! Drinking the right amount of coffee can prevent Alzheimer’s disease?
Coffee can interfere with brain aging, a few cups a day to reduce the risk of cognitive impairment by 69%
Have you had your coffee today? A sip of coffee, sweet with a bit of bitterness, this is the taste of coffee, but also the taste of life! “Coffee” always follows us to start our busy day, accompanying us to stay up late, work overtime, and also accompany us to enjoy the afternoon. In the face of the modern fear of dementia, did you know that drinking coffee may also be a preventive method?
Studies have shown that moderate caffeine intake can reduce the risk of dementia
In recent years, many studies have shown that long-term coffee consumption can help prevent Alzheimer’s disease and dementia. According to Medical Daily, a study published in The Journals of Gerontology in 2016 stated that
The study’s respondents were 6467 women aged 65 to 80, 388 of whom were diagnosed with a high risk of dementia, and the study recorded their self-reported caffeine intake for 10 consecutive years. The results found that compared to less frequent coffee drinkers (less than 64 mg of caffeine per day), more frequent coffee drinkers (more than 261 mg of caffeine per day) had a 36% lower risk of dementia.
Researchers say that the relationship between caffeine intake and dementia risk cannot be directly linked to each other, but the study points out that caffeine helps protect cognitive function because it can bind to the brain’s adenosine receptors, interfering with normal aging and aging-related pathologies to achieve health effects.
However, the women in this study had already reached menopause and were more educated, so the results may not be representative of all female populations. In addition, the researchers did not specifically account for sources of caffeine other than coffee and tea, so the actual caffeine intake of these respondents may be higher. Science Daily reported that an Italian study published in the Journal of Alzheimer’s Disease in 2015 looked at 1,445 Italians with normal cognitive function, aged 65 to 84 years old, and conducted a study on coffee consumption. The study found that the amount of coffee consumed by 1445 Italian people with normal cognitive function, aged 65 to 84 years old.
The results found that people who drank one to two cups of coffee a day for a long time had a lower risk of mild cognitive impairment (MCI) than those who never drank coffee or drank very little. Those who drank one cup a day had a 53% lower risk of MCI, and those who drank one to two cups a day had a 69% lower risk of MCI. However, there was no significant change in the risk of MCI for those who drank more than 2 cups of coffee per day compared to those who never drank or rarely drank coffee. Therefore, the researchers suggest that regular and moderate coffee consumption may help protect the nerves and reduce the risk of MCI, which supports the argument that “long-term caffeine intake helps prevent dementia” in some previous studies.
Why can coffee improve Alzheimer’s disease?
Why can coffee improve Alzheimer’s disease? Research suggests that it has to do with these two ingredients contained in coffee!
Why does coffee have these effects? Researchers believe that it may be the effect of caffeine and antioxidants. According to the science news site EurekAlert, a report presented at the 2014 Alzheimer Europe Annual Congress, caffeine can help prevent the formation of Alzheimer’s disease, and both caffeine and polyphenols can reduce the inflammation and degeneration of brain cells.
In this way, it seems that moderate coffee can really help prevent Alzheimer’s disease, dementia, which is really good news for people who love coffee! However, the more coffee you drink, the better, because too much caffeine can cause insomnia, palpitations, tremors, agitation and other symptoms, and even block the absorption of calcium.
In addition, each person can tolerate the amount of caffeine are different, some people are even more sensitive to caffeine, drink it will have a headache, so should be adjusted according to their own circumstances, do not drink exactly according to the above-mentioned studies in the amount of servings. At present, the European Commission of Food Science experts recommend that the daily intake of caffeine does not exceed 300 mg.
As for the prevention of dementia, coffee may be one of the influencing factors, but it also needs to be combined with sufficient sleep, regular exercise, balanced diet, stress relief and other good lifestyle habits in order to minimize the risk of dementia, not just rely on coffee.
In addition, it is recommended that pregnant mothers, breastfeeding mothers, people with excessive stomach acidity, and people prone to diarrhea avoid drinking coffee, and people in general should avoid drinking on an empty stomach and after exercise in order to enjoy the aroma of coffee without affecting their health.
