10 years ago I stopped using sugar, I found it took a long time to get used to the taste of my coffee without sugar and I was expecting it to be the same trying to switch to black coffee. I know it’s only my first cup of black coffee but I actually like it more than I do with milk. So much so that I was motivated to leave this post. More simple, much better.
Cuban tradition is to drink coffee strong and sweet, often mixing the sugar with the coffee beans before brewing. The traditional method of brewing coffee was a filter method using a cloth cone; this has mostly been replaced with an aluminium cafetera or coffeemaker—in tourist areas some cafés will have an espresso machine, though espresso machines are expensive, so espresso is not a common drink for most Cubans.[31][32] Though quality coffee is grown in Cuba, it is expensive, so most Cubans drink coffee imported from Puerto Rico, and often mixed with ground peas.[33][34] The Cuban habit of brewing coffee with sugar has spread to Miami, West Palm Beach, Tampa and the Keys, in Florida, US, where espresso is the preferred brewing method and an espresso brewed with sugar is termed Café Cubano, Cuban coffee, Cuban espresso, cafecito, Cuban pull, or Cuban shot.[35] Sometimes demerara sugar is used, and sometimes the sugar (white or brown) is not brewed with the coffee, but is placed in the cup as the coffee is dripped into it, then stirred into a froth.[36][37] Variations on the Miami café Cubano are with a splash of milk - cortadito; and with steamed milk - café con leche.[38]

I don’t have a problem with people adding things to their coffee (my wife enjoys her coffee with cream and minimal disapproving head shakes from me) but I do think black coffee has its merits. It is my opinion that the vast majority of coffee additives are remnants from the first wave coffee notion that coffee is vile, caffeine is good and adding things to coffee makes it tolerable.
Coffee offers a wealth of health benefits — there's its well-known ability to temporarily boost concentration and alertness, and drinking coffee might also lower your risk of liver disease and type 2 diabetes, explains the Linus Pauling Institute. Black coffee is a healthier alternative to coffee flavored with calorie-laden cream and sugar, and it might also help you lose weight. Just make sure you don't overdo it — too much caffeine can have negative health effects.
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.

Good news to all those coffee lovers out there: That cup of joe has quite a few health benefits, as long as you don't load it up with cream and sugar. A number of health organizations agree: The World Health Organization in June 2016 took coffee off the list of potentially carcinogenic foods, stating that java possibly protects again certain cancers, while the 2015 Dietary Guidelines Advisory Committee declared that three to five cups of coffee a day can be part of a healthy dietary pattern. In fact, research shows that black coffee can have a positive effect on conditions including diabetes, dementia and depression.
