Limit coffee intake to 400 mg daily, says nutritionist

Nutritionists recommend that adults limit their caffeine intake to about 400 milligrams per day. This is roughly equivalent to four cups of coffee. However, the amount of caffeine can vary depending on the type of coffee consumed. An espresso usually has about 80 mg of caffeine per 30 ml serving. A regular filter coffee can contain between 80 and 120 mg in a 240 ml cup. Instant coffee has lower levels, with 30 to 90 mg of caffeine for the same amount. The way your body processes caffeine can also affect how you should approach coffee consumption. Some people can drink coffee right before bed without any issues. Others may find that doing so keeps them awake at night. Each person's tolerance to caffeine is different. For that reason, listeners are encouraged to pay attention to how their body reacts to coffee.
