Key Messages
These these science-backed key messages to confidently answer questions and guide conversations about protein.
- What is protein? Protein is an essential macronutrient that supports overall health. It helps build and maintain muscles and plays a key role in many body processes, including the production of hormones, neurotransmitters and enzymes. Proteins are made of amino acids, nine of which your body cannot make on its own. These “essential amino acids” must come from the foods you eat.[1],[2],[3]
- Where can you find protein? Protein is found in a wide variety of foods. The Dietary Guidelines for Americans recommend including both plant and animal sources such as lean meats and poultry; seafood; eggs; low-fat dairy (milk, yogurt, cheese); beans, peas, lentils; soybeans and soy products such as tofu or tempeh; and nuts and seeds.[4]
- How much protein do you need? Protein needs vary based on age, health and activity level. The Recommended Daily Allowance (RDA) for protein is 0.8 grams per kilogram of body weight per day for adults 18 years and older.[3],[5] That’s about 64 grams per day for someone weighing 175 pounds. Most people meet this through their regular diet. Some groups – like pregnant or breastfeeding individuals, athletes and people using certain weight loss medications – may need more.[6]
