Introduction

There are 4 calories in one gram of Protein. Proteins are organic molecules made up of Amino acids and are one of the essential parts of the diet. The importance of protein in the body is very much high. Protein is required from the body's structure to function and regulate. Proteins are the basics of skin, hair, enzymes, antibiotics, etc. They are complex by their structure and are divided into different levels- Primary, Secondary, Tertiary and Quaternary. Since the human body cannot store amino acids, it gets protein from starch or by modifying others. There are nine essential amino acids. They are methionine, phenylalanine, lysine, leucine, isoleucine, histidine, threonine, tryptophan and valine. They must come from food only.

What do you mean by Calories?

A calorie can be considered a measurement of energy released from food on being absorbed by the body. The energy provided to the body is directly proportional to the amount of food intake by the human. Eating extra calories might result in excess body fat as the body stores extra calories in fat. Usually, it has a measuring unit KCal or Kilocalories.

According to the National Academy of Medicine, a human body of an adult should get a minimum of 0.8 grams per every kilogram of their body weight or 7 grams per every 20 pounds.

A person weighing about 140 pounds should intake 50 grams of protein daily. A person weighing about 200 pounds should intake 70 grams of protein daily. There is no ideal information about the perfect amount of protein to be consumed daily, but a portion of 10% to 35% of the calorie intake is acceptable every day.

A deficiency in protein from the everyday diet could fail growth, loss of muscle mass, less immunity, and weaken the respiratory system and heart.

1 Gram of Protein

Just like any food item or nutrient, protein also contains calories. Since on packaged items, the calories are shown per 100 g, the calories in a hundred grams of protein content are 401. Therefore, 1 gram of protein contains 4 calories.

The amino acids are joined to each other by peptide bonds and form polypeptides. Many of the vital amino acids can be acquired through supplements of protein. The importance of protein in the human body is so much that a deficiency can cause muscle weakness, hair loss, etc.

This information is available on almost all food labels, and observing this information is a good practice. The suggested intake of proteins varies based on our age and amount of activity. However, the average person needs 50 grams of protein per day. We can easily meet this need if you eat a variety of high-protein foods.

Foods that are Rich in Protein

Several foods are high in protein, such as meat, chicken, fish, eggs, dairy goods, legumes, and nuts. These foods would be a good option if we wanted to increase the amount of protein in our diet. Additionally, we can choose plant-based proteins like tofu, quinoa, and black beans.

Animal-based proteins are typically regarded as the highest quality since they have all the key amino acids that human systems require. However, plant-based proteins are also a good choice if we adopt a vegetarian or vegan diet.

Chicken, beef, eggs, milk, cheese, yoghurt, tofu, pork, lamb, salmon, tuna, quinoa, and black beans are a few of the top high-protein foods. Along with helping us to achieve our protein requirements, these meals also provide us with vital elements, including iron and vitamin B12.

Conclusion

Protein is the main nutrient when it comes to maintaining the body. It has a wide range of sources, both for vegetarians and non-vegetarians. A few high riched protein sources are Meat, eggs, pulses, and dairy products like Milk, Curd, etc. Apart from them, Soy is a very good source of high protein. To maintain the body, a diet which is moderately high in protein and low in fats and calories should be picked.
