A Guide to Protein Serving Sizes
Protein is one powerhouse nutrient. It helps keep you full, and your body uses it to help grow and maintain muscles, blood vessels, skin, hair and nails. Plus, protein also plays a key role in synthesizing hormones and enzymes in your body.
Protein is found in a variety of foods, including meat, poultry, seafood, dairy, beans, nuts and whole grains. According to the USDA Dietary Guidelines, women need about 46 grams of protein and men need around 56 grams of protein (but this does vary depending on how many calories you eat each day). Learn exactly how much protein you need to eat every day. Your protein needs are also dependent on your age, activity level and whether you are pregnant or have any chronic diseases.
If you eat a balanced diet, you are likely getting the daily required amount without much difficulty. A standard 3-ounce chicken breast has about 26 grams of protein in it, which is more than half of what's recommended for women. But despite the fact that most people get enough protein, it remains a popular macronutrient to eat. It helps keep you full (read: less hangry) and powers up your muscles.
To make it easier for you to eat up, we looked at what a serving of protein looks like and how much you're getting from different sources.
