Actually, you don’t lack it? Experts reveal why most people don t need extra protein foods at all

The human body needs protein; protein is responsible for many functions in the cells, and is very important for the growth, repair and maintenance of muscles, bones and skin; and with food companies launching a variety of high-protein foods, including milkshakes, swim bars, and even pancakes and popcorn, you may feel that you need to add more protein to your diet.

But nutritionists point out that if you have enough food, you may also have enough protein.

"Putting protein into food is very beneficial for manufacturers to make money," Federica, chief nutritionist at Imperial College London and health science company ZOE "This is neither in line with health nor scientific research." The amount of protein intake required by each person varies depending on your age, weight and personal nutritional needs; it is especially important for children and the elderly to get protein-rich foods.

Protein is important so that your body knows how to make it

Protein is a huge amount of nutrients, or a basic food for the body to operate like fat or carbohydrates; protein is composed of thousands of small molecules called amino acids, most of which can be synthesized by the body itself.

If you don't feel hungry, you may have taken enough protein

World Health Organization (WHO) suggests that healthy adults need to take about 0.4 grams of protein per pound; for a man weighing 165 pounds and a woman weighing 143 pounds, men should take about 60 grams of protein per day, and women should take about 50 grams of protein per day.

Protein is found in many foods

Plant protein sources include beans, lentils, peas, fruits, seeds, tofu, fermented black beans and meat substitutes; fish, meat, poultry, eggs, and dairy products such as milk and elegance are also good sources of protein. Compared to plant-based proteins with more fibers, animal-based proteins may be more likely to be broken down by humans, Amati said.

You probably don't need to buy protein-added products

Benelam of the British Nutrition Foundation pointed out: "Unless you need to get more protein due to special health problems, most people in the United States and the United Kingdom do not need to get more protein."

For those who want to increase muscle, Benelam advises: "If you are worried about your body shape and strength, you should do a retraining and give your body some challenges; eating protein bars is useless."
