Many studies have proven that drinking caffeine during pregnancy might affect the growing fetus. Black coffee, being a rich source of caffeine, can increase the metabolic activity and heart rate. The growing fetus does not have enough strength to withstand this increase in heart rate. Black coffee and other caffeine drinks must be avoided during early pregnancy.
Cold brew coffee originated in Japan, where it has been a traditional method of coffee brewing for centuries. Slow-drip cold brew, also known as Kyoto-style, or as Dutch coffee in East Asia (after the name of coffee essences brought to Asia by the Dutch), refers to a process in which water is dripped through coffee grounds at room temperature over the course of many hours. Cold brew can be infused with nitrogen to make nitro cold brew coffee.
Those who drink coffee regularly have a 20% less risk for stroke, and generally have lower rates of heart disease. As caffeine increases your heart rate, coffee is actually good for cardiovascular health. Drinking a few cups of coffee a day has a similar effect to going for a walk, which keeps your heart healthier. Please do not use this as an excuse to not exercise, though. It doesn’t work quite that well.
