Protein is an essential nutrient, and it's found in many foods. But all foods are not created equal, and some are better than others for maximizing your optimal protein intake.
Protein is present throughout the body. It's in muscle, bone, skin, and almost every other body part or tissue. It is what the enzymes are made of that power many organic reactions in the body, and the hemoglobin that carries oxygen in your blood.
Many nutritional agencies recommend that adults get a minimum of 0.8 grams of protein for every kilogram of body weight per day, or just over 7 grams for every 20 pounds of body weight. The exact requirement varies depending on who you talk to. Some say it's much less and others say it's much more.
Asparagus is a lowly of protein and if you're looking to increase your protein intake then asparagus is not the best choice. But it's a food that is low in calories, low in carbohydrate and high in vitamins and minerals which makes it healthy and is recommended as part of your weekly diet regime.
Eat and enjoy.
