Foods high in simple sugars include fruits such as dates, grapes, raisins, apples and bananas, according to Kevin Rail for SFGate. Vegetables such as sweet potatoes, carrots and peas also contain high amounts of simple sugars. Honey contains one of the highest amounts of simple sugars of any food, at 17 grams per tablespoon. Unlike table sugar, however, honey also contains vitamins and minerals.
Simple sugars are also known as simple carbs. They are digested quickly by the body, which turns the simple sugars into glucose, and provide an immediate burst of energy, explains Rail. If such energy is not used right away, it is stored in the liver or muscles for later use. The natural form of these sugars in fruits is known as fructose. Certain fruits such as raisins and dates contain the largest amount of fructose per serving; there are 79 grams in half a cup of raisins and 69 grams in approximately 10 dates.
Dairy foods may also contain simple sugars in the form of lactose, states Rail. Milk and yogurt contain a high amount of lactose. A cup of whole milk contains approximately 12 grams of carbs, and a cup of plain yogurt contains about 11 grams. Along with healthy doses of protein, such products are also high in calcium, which strengthens bones and teeth and assists in the process of muscle contraction.
