Many previous studies have focused solely on the health effects of coffee or tea,** both separately. For example, epidemiological and clinical studies have found that coffee and tea are beneficial in preventing dementia, respectively, but few studies have discussed the combined effects of the two.

In fact, coffee is closely related to the consumption of tea, with about 70% of people citing both coffee and tea. So when the two drink together, is it a strong combination or a positive and negative?

A team from Tianjin Medical University conducted a study on the combined effect of "coffee + tea", and the results showed that coffee and tea, whether drunk alone or together, have the effect of reducing the risk of stroke and dementia, and drinking 2-3 cups of coffee + 2-3 cups of tea per day can reduce the risk of stroke by 32% and the risk of dementia by 28%. The study was published in PLOS Medicine.

This prospective cohort study included 365,682 participants from the UK Biobank, who were followed for up to 10-14 years. Among the 10,000 participants, men were male, ranging in age from 50 to 74 years old, with an average age.

This large prospective cohort study found:

1.Tea and coffee, whether consumed alone or in combination, are associated with a reduced risk of stroke, ischemic stroke, dementia, and vascular dementia; 2.Drinking coffee and tea together is associated with a lower risk of stroke and dementia than drinking coffee or tea alone; 3.

Participants who drank 2-3 cups of coffee and 2-3 cups of tea per day had about a 30% lower risk of stroke and dementia.

Overall, this study suggests that moderate consumption of coffee and tea, either alone or in combination, is associated with a lower risk of stroke and dementia. If you usually want to drink drinks, you can use coffee and tea as the best choice, which has a certain brain-protecting effect.

Among the respondents who drank coffee, there were those who were accustomed to drinking instant coffee, drinking ground coffee, and drinking decaffeinated coffee. Data analysis showed no significant difference in the ability of instant coffee and decaffeinated coffee to reduce the risk of stroke, but ground coffee was associated with a 10% reduction in the risk of stroke and ischemic stroke.

For dementia risk, ground coffee reduced the risk of dementia, Alzheimer's disease, and vascular dementia, respectively, compared with instant coffee. Compared with decaffeinated coffee, instant coffee also reduced the risk of dementia, Alzheimer's disease, and vascular dementia, respectively, and ground coffee reduced the risk of dementia, Alzheimer's disease, and vascular dementia.

So, when choosing coffee: ground coffee > instant coffee > decaffeinated coffee.
