Cheese melted over chips to make nachos, added to a casserole or included in a dip is a high-calorie, high-fat indulgence. Melted cheese is a source of bone-building calcium and phosphorus but also provides high amounts of cholesterol and sodium. Before making melted cheese a regular part of your diet, understand the impact it may have on your nutrition intake.

Melted cheese contains more fat and calories than shredded or diced cheese because there is no air taking up space in each serving. For example, a cup of diced cheddar cheese weighs 132 g, a cup of shredded cheddar cheese weighs 113 g and a cup of melted cheddar weighs 244 g. By melting cheese, you get more cheese per serving – and more of the calories and nutrients.

One cup of melted cheddar cheese contains 983 calories. Cheese is low in carbohydrates, with a cup of melted cheddar offering just 3 g. You also get 61 g of protein by consuming a cup of melted cheddar. Of the 81 g of fat, 51 g are saturated. The American Heart Association recommends limiting saturated fat intake to less than 7 percent of total daily calories. For a 2,000 calorie diet, this is just 15 g per day.

Although melting the cheese concentrates the calories and fat, it also concentrates the nutrition. One cup of melted cheddar provides 176 percent of the recommended dietary allowance for calcium, based on a 2,000-calorie diet. It also provides 125 percent for phosphorus, 49 percent for vitamin A, 54 percent for riboflavin, 48 percent for selenium, 51 percent for zinc and 34 percent for vitamin B-12. Melted cheese contains smaller amounts of additional vitamins and minerals, including 17 percent for magnesium, 10 percent for pantothenic acid, 11 percent for folate, 9 percent for vitamin B-6, 9 percent for vitamin K, 7 percent for vitamin D and 9 percent for iron.

One cup of melted cheese provides 256 mg of cholesterol – nearly a full day’s worth. The American Heart Association recommends sticking to 300 mg of cholesterol or less each day to protect heart health. If you have been diagnosed with high cholesterol, you are advised to stay below 200 mg daily. The cup of melted cheddar also provides 1,515 mg of sodium. The Institute of Medicine encourages limiting sodium consumption to 1,500 mg per day.

Other types of cheese may have slightly different nutrition information when melted because they have different nutrition information when shredded. Part-skim mozzarella is slightly lower in fat and calories than cheddar, for example. If your recipe calls for melted cheese, measure it before melting and stick to moderate 1- to 1 1/2-oz. portion sizes to keep calories and saturated fat in check.
