Differences Between Protein Malnutrition & Calorie Malnutrition

A protein is an organic compound made up of amino acids; a calorie is a unit of energy derived from foods we eat, including those that contain protein. Health risks are associated with both protein and calorie malnutrition.

Protein

• Protein is a nutrient found in foods such as meat, dairy products, seafood, eggs, nuts, seeds, beans, peas and grain. Adults should consume a minimum of .8 grams of protein for every kilogram of body weight each day.

Calorie

• Calories represent the energy provided by food; people often count calories when they diet and to keep track of energy expended during exercise. Almost everything we eat and drink has calories. Protein contains 4 calories per gram.

Protein Malnutrition

• In protein malnutrition, the diet provides inadequate protein, which can cause health problems such as lack of muscle development, heart problems, loss of muscle mass, decreased immunity, growth impairment and respiratory problems. When severe, protein malnutrition can lead to death.

Calorie Malnutrition

• In calorie malnutrition, the diet is not correct or is not providing enough food, or both. People can consume sufficient calories and still be deficient in needed vitamins and nutrients. Proper management of calorie intake means choosing healthy foods to make calories count, as well as consuming enough food. Calorie malnutrition can result in weight loss, fatigue, heart problems and many other health issues related to nutrient and vitamin deficiency.

Prevention/Solution

• The recommended amount of protein and calorie intake depend on factors such as weight, gender, age and amount of physical activity. The U.S. Food and Drug Administration recommends around 2,000 calories per day for the average adult female (with at least 600 of those calories coming from fat) and around 2,500 calories per day for the average adult male (with 750 calories coming from fat).
