Sugar is a carbohydrate, which your body uses as a source of energy. It’s found naturally in foods such as fruit, vegetables, dairy products and some meats.

Sugar can also be made from sugarcane or sugar beets.

Sugar comes in many different forms, including sucrose (table sugar), glucose (dextrose) and fructose (fruit sugar). Some of these are naturally occurring and others are chemically manufactured.

Sugar is about 15 percent water, so you can use that to estimate how much water is present in a teaspoon (3 grams) of table sugar. A teaspoon of table sugar contains 3 grams of carbohydrates and 15 calories.

A cup of coffee has between 116-168 milligrams of caffeine depending on brewing method used. Caffeine acts as a stimulant by blocking adenosine receptors in the brain and increasing dopamine activity when it binds to them instead. This makes you feel more alert and causes an increase in heart rate and blood pressure.
