Folgers Instant Coffee in either regular or decaf versions offers only trace amounts of minerals and vitamins as well as some carbohydrate, fat and protein. None of these nutrients occurs in significant amounts in a single cup. Calories and nutrient levels vary slightly depending on the type. Shifting to the instant Folgers Cappuccino increases calories significantly but adds very little nutritive content beyond the additional carbohydrates and fats.

Folgers Instant Decaffeinated coffee actually contains more carbohydrates and protein than the regular Folgers Instant with caffeine. Folgers Classic Roast Instant Coffee Crystals provides two calories from 0.4 g of carbohydrate and 0.1 g of protein. The decaffeinated version doubles the calories by doubling both the carbohydrate and protein levels.
Data provided by the National Nutrient Database gives a slightly different picture of instant coffee's actual content although the database doesn't single out Folgers. By this standard, the instant coffee tested yielded four calories and insignificant amounts of minerals including copper, iron, magnesium and sodium. Potassium outweighed other minerals in the blend with 54 mg per tsp. Colorado State University lists the recommended minimum daily requirement of potassium as 4.7 g, so the amount in instant coffee contributes little to the daily minimum requirement.
National Nutrient Database measurements of vitamin content in powdered instant coffee revealed niacin as the only vitamin present in amounts greater than 0.002 mg. The 0.422 mg of niacin detected in 1 tsp. of instant coffee provides only about 3 percent of the minimum daily requirement for an average adult.

Although both original versions of Folgers instant coffee--regular and decaffeinated--qualify as low calorie drinks, the newer Folgers Instant Cappuccino adds 80 calories to a 3 tsp. serving. The single serving of cappuccino powder contains 2 g of fat, 16 g of carbohydrates, and 11 g of sugars. Folgers Instant Cappuccino contains 105 mg of sodium and one g of protein. The cappuccino also provides 4 percent of the minimum daily requirement of calcium.
Even though the nutritional value of instant coffee seems low, coffee contributes complex beneficial chemical compounds to the diet. Even just a half cup of coffee daily could help protect you from some types of brain cancer. Coffee may lessen the risk of Alzheimer's and help prevent Parkinson's Disease. Coffee also benefits the liver. Drinking a cup of coffee three or more times a day makes hepatitis C patients 53 percent less likely to develop progressive liver damage than patients who drink no coffee at all.
