Proteins are large, intricate molecules that perform a variety of essential functions in the body. They are vital for the structure, operation, and regulation of the body’s tissues and organs, with most of their work occurring inside cells. Proteins are made by linking thousands of amino acids, the smaller building blocks, together in long chains. The order and structure of these amino acids determine the protein’s function.
There are 20 distinct types of amino acids that can combine to form a protein. The specific order of amino acids determines the protein’s function and its 3D structure. Proteins are essential because their diverse structures and complex arrangements allow them to carry out a wide range of activities in the body.
Your body constantly builds and repairs tissues, and protein is essential for this process. During times of illness, pregnancy, or recovery from surgery, your body may need more protein than it typically produces. Protein is also crucial for the production of enzymes and hormones, which help regulate metabolism, digestion, and other biochemical reactions in the body.
Protein needs vary from person to person, but consuming the right amount is essential for health. Foods high in protein include seafood, poultry, dairy products, eggs, beans, and lean meats. For those on vegetarian or vegan diets, plant-based sources like lentils, beans, and tofu provide excellent protein alternatives.
For example, salmon is rich in omega-3 fats and protein, while dairy products like milk, cheese, and yogurt are excellent sources of both protein and essential vitamins like calcium and vitamin D. Beans and lentils are packed with plant-based protein, fiber, and various essential nutrients.
The amount of protein you need depends on various factors, such as weight, age, sex, and activity level. Generally, healthy adults require 0.8 grams of protein per kilogram of body weight. For example, an average sedentary woman needs about 45 grams of protein per day, while an average sedentary man needs around 55 grams.
If you're physically active, pregnant, nursing, or recovering from surgery, your protein needs may be higher. It’s important to tailor your protein intake to your individual health requirements.
