How Much Protein Does Fresh Carrot Juice Have?

One cup of carrot juice contains 94 calories.

Carrot juice, obviously made from fresh carrots, is often used as a health food because it's low in fat, calories and sugar. It also supplies a good dose of many key nutrients, including a small amount of protein. Chilled carrot juice is available at most health food stores, as well as many large supermarkets, which makes it easy for you to add to your diet.

Protein in Carrot Juice

A 1-cup serving of carrot juice contains approximately 2 grams of protein. That's not much toward the daily recommendation of 8 grams per 20 pounds of body weight. For example, if you weigh 120 pounds, you should aim to eat 48 grams of protein each day. A cup of carrot juice is only about 5 percent of that goal.

Importance of Protein

Proteins are the building blocks of life, and without it, you wouldn't be able to survive. Protein is essential for most of the things your body does such as move, think and grow. Without enough protein, you can experience decreased muscle mass, reduced immunity and weakening of your heart, according to the Harvard School of Public Health. It's rare for people living in the United States to become deficient in protein since there's access to a wide variety of protein-rich foods such as meat, beans, nuts, seeds and dairy products.

Additional Nutrients

One cup of carrot juice supplies 2,256 micrograms of vitamin A. That's 320 percent of the 700 micrograms women should have each day as part of a healthy diet. It's 250 percent of the 900 micrograms men need on a daily basis. Vitamin A keeps your retinas healthy so you can see normally, especially in low light. The nutrient also aids the formation of genes and keeps your immune system strong. The same cup of carrot juice delivers 20 milligrams of vitamin C, which is 27 percent of the 75 milligrams women need each day and 22 percent of the 90 milligrams men should have. Vitamin C is another nutrient that keeps your immune system strong and healthy. You'll also get a good dose of vitamin E, which protects your cells from damage, as well as potassium for a healthy heart.

Drinking Carrot Juice

The easiest way to add carrot juice to your healthy diet is to drink a glass of the juice chilled. Many people, however, don't really care for the taste of straight carrot juice, because it isn't as sweet as fruit juices. Mix equal parts of carrot juice and 100 percent apple juice to make it sweeter and more flavorful. Add carrot juice to pasta sauce or soup to boost nutrition. Add a bit of carrot juice to the cooking liquid you use to cook pasta, rice or other grains. It'll add flavor, as well as a healthy dose of vitamin A. You could also use carrot juice in your favorite smoothie recipe.
