Calculate the calorific value of food items you consume by adding the protein, carbohydrates and fat by gram. On the back of food packs you would often find, for each serving, food details.
Proteins are the fundamental building blocks of all living organisms, typically consisting of a chain of amino acids. They are involved in many different bodily functions, including structural support, immunological function, regulation of metabolic processes, and enzymatic activity. There are 20 natural amino acids that can be combined to form proteins. Of these 20 amino acids, three serve as the building blocks for all other amino acids: glycine, alanine, and valine.
The human body is made of many cells, and these cells are filled with proteins. Proteins, which are large molecules that form chains, play a vital role in our bodily functions. They help to regulate temperature, synthesize DNA and RNA for new cell growth, and produce antibodies that protect against bacteria and viruses. There are thousands of different types of proteins that each do different things: some help us to grow hair while others control the movement of water through our body.
Proteins are one of the most important molecules in cells. They carry out a wide range of functions such as DNA transcription and replication, cell division, transport of substances through membranes, and more. How do they work? Protein structures can be separated into two different categories: globular and fibrous proteins. Globular proteins consist of polymers of amino acids that form spherical shapes like balls or bubbles.
Protein helps build and prevent loss of muscle while keeping you satisfied for longer. It requires more energy to digest in the body than other macronutrients. Examples of supporting sources include:
Carbohydrates are one of the three main macronutrients that make up food. Carbohydrates provide energy for the body and help regulate blood sugar levels. Carbohydrates are found in many different foods like bread, cereal, rice, pasta, vegetables, potatoes, beans, fruits, and dairy products. All carbohydrates are made up of sugars or starches. Simple carbohydrates are sugars like table sugar or honey; complex carbohydrates are starches like flour or potatoes.
Carbohydrates are the key source of energy for all living organisms. Carbs provide energy for your brain, muscles, and other cells. The amount of carbohydrates you eat is important because they affect weight gain, cholesterol levels, and diabetes risk. The more carbs you eat, the higher your blood sugar levels will be.
The human body breaks down carbohydrates to produce energy. When you eat, your body breaks down food into glucose sugars to provide energy for cells throughout the body. The liver and muscles store glucose as glycogen for instant use when needed or other organs can convert glucose into fat or other types of sugars called ketones.
Carbohydrates are often categorized into simple and complicated carbs, depending on how easily they can be broken down by the body. While carbohydrate foods such as fruit, vegetables, and grains are all packed with energy that is stored as glycogen, they are often also high in vitamins and fiber. Several examples of carbohydrate-rich food sources include:
Fats are an essential component of a healthy diet. They provide energy, help with fat-soluble vitamin absorption, and have been shown to have anti-inflammatory effects. A diet rich in all three macronutrients is best for maintaining healthy body weight and general well-being.

Fats are a necessary part of a healthy diet and serve many essential roles in the body. They help form and maintain cell membranes and insulate the body from cold weather. Fat is also needed to create hormones and other chemical signals that regulate bodily functions. There are two types of fats: saturated and unsaturated.
Fats play a critical role in nutrient absorption, brain function, and the regulation of hormones, among other important physiological processes. Some helpful sources of fat include:
