Coffee can also improve memory. With the increase of age, stress hormones in the brain will accumulate continuously, which will affect memory. Caffeine can block and protect receptors related to aging and stress, thus delaying the aging process. The safe upper limit of caffeine intake is 400 mg per day, which is equivalent to 4 cups of coffee. So, although drinking coffee has many benefits, don't be greedy.
Extended data:
Before drinking coffee, you should pay attention to the following matters:
1, coffee with low-fat milk, no cream. Low-fat milk has less calories, which helps to offset the loss of calcium (a spoonful of low-fat milk has only 6 calories, but the calcium content is 19 mg).
Don't add sugar to coffee. Eating a lot of sweetened coffee every day will increase calories.
People with high cholesterol, please drink filtered coffee. Because unfiltered coffee usually retains a high cholesterol substance called caffeic alcohol, which may lead to an increase in cholesterol levels.
If you have difficulty falling asleep, please avoid drinking coffee at night or before going to bed.
