The Ministry of Health says some people are particularly sensitive to caffeine and eating small amounts of caffeine can already show these symptoms.

The average adult should take no more than 400 milligrams a day. The largest Blonde Roast caffeine in a cup of Starbucks alone is 475mg, more than the daily intake of adults recommended by the Ministry of Health, while the medium cup contains 360mg. Other low caffeine levels at Starbucks include lattes, cappuccinos and Flat White, with a maximum of 195mg.

Who should pay special attention?

Pregnant woman

Women who are pregnant, breast-feeding and pregnant are not recommended to eat more than 300mg a day, which is equivalent to a large cup of Tim Hortons coffee.

Children

The older children are, the more likely they are to receive caffeine. Children between the ages of 4 and 6 should not consume more than 45 milligrams of caffeine a day, equivalent to less than half a cup of Tim Hortons coffee. Children between the ages of 7 and 9 can eat 62.5mg a day and less than half a cup of small Tim Hortons coffee. Children aged 10 to 12 can drink half a cup of small Tim Hortons coffee every day. Caffeine intake should not exceed 2.5 mg per kilogram of body weight for people over the age of 13. If a child weighs 40 kilograms, he can eat 40 milligrams and 2.5 milligrams (100 milligrams) of caffeine a day.

Healthy adults who do not consume caffeine regularly and women who are pregnant or breastfeeding tend to metabolize caffeine more slowly, and the response to caffeine is relatively longer than that of adults who regularly consume caffeine.

Energy drinks can affect heart health

Other ingredients in energy drinks may affect heart health, a new study has found. A survey by Canadian researchers shows that 76% of young people between the ages of 12 and 24 drink energy drinks, and 16% drink more than two cans a day. Health Canada recommends no more than two cans a day.

The Journal of the American Association of Cardiology published the results of a small study of 18 healthy adults who were asked to drink two cans of energy drinks sold on the market every day, while a control group drank only the same amount of caffeine. Drinks that contain no other ingredients. The researchers used electrocardiograms (ECG) to track changes in heart activity 24 hours after drinking a drink, including changes in QTc, a related indicator that causes arrhythmias and can be life-threatening. The small sample study showed that people who drank energy drinks had significantly higher levels of QTc than those who drank only caffeinated drinks.

Health Canada has warned that a variety of ingredients in energy drinks, such as taurine, L-ferritin and ginseng, can change heart rhythm. Professor Michelle Reid (Michael Rieder) of the University of Western Ontario in London, Canada, said: "if you drink a can of energy drink every day, it may not be a problem. But if you drink three or four cans, you must be careful. He advises parents and doctors to monitor the drinking of young people between the ages of 12 and 24, telling them how to reduce risk and how to be responsible for their health.

When combined with alcohol or other stimulants, energy drinks are more likely to trigger cardiovascular disease and need to be more cautious.
