Your body is full of protein, it runs through your muscles, bones, skin, hair and pretty much everywhere else. Beyond its structural role, protein does the most important chemical tasks. It powers the enzymes that drive reactions in your body and forms hemoglobin that carries oxygen through your blood.
That is why people call human proteins the basic building blocks of life. Your body breaks it into amino acids that later rebuild and fix the tissues as needed.
What Protein Does and Where to Find It
How does it work so well? Chains of proteins are made up of amino acids tied one to another. Around 20 different amino acids move around in the body, and they combine in endless ways to create various proteins.
If your body requires some new element; muscle fibers, bone density or whatever, it arranges those amino acids in long chains that hold togehter with peptide links.
Where do you get protein? Meat, poultry, fish, beans, peas, lentils, eggs, nuts, seeds and soy all give large amounts. Beyond just protein, you get B-vitamins, vitamin E, iron, zinc and magnesium.
Animal sources usually provide complete proteins rich in minerals, although there is debate about the content of packed fat compared too plant options. Not every protein food is innocent when it comes to levels of fat.
The choice of good sources depends on your eating style. Egg whites, chicken and dairy rank among the purest options. For vegetarians the task becomes a bit harder…
Most plant-based proteins come with many carbs. Tofu works well stir-fried or air-fried or crumbled in burritos. Textured plant protein works well in tacos and sauces.
Beans and lentils shine in stews and broths. Combine grains with vegetables. For instance beans with rice or quinoa, and you will have a firm nutritious base.
Cheese, lentils, vegetables and mushrooms all bring protein to thetable without too much cost.
How much do you truly need? The standard advice for a sitting adult moves around 0.8 grams for every kilo of body weight. Folk weighing 165 pounds, which matches around 75 kilos, aim for about 60 grams a day.
For growing children and pregnant or nursing women the need rises, because their bodies build extra tissue. If you have kidney problems, stay at that 0.8-gram standard per kilo (your kidneys will thank you for it). Athletes and lifters who train hard commonly aim for higher amounts.
Getting enough is not as hard as it sounds. A normal three-ounce piece of chicken gives around 26 grams of protein, more than half of your daily minimum. Most folks reach 15 to 30 grams each meal without big effort.
Protein powders provide about 20 to 30 grams each serving, while bars can reach 40 or more. Whey protein is the favorite for muscle growth. Plain soy protein stays neutral in taste and blends well into smoothies or broths.
Pure powder stores usually 70 to 80 percent of protein per weight.
