Difference between kcal and calories

Calories indicate the specific amount of energy that food or beverages contain. The same energy is often also measured in or defined by kilocalories (kcal) or kilojoules (kJ). 1 calorie is equal to 4.18 kilojoules. Or, 1 calorie is equal to 4,184 joules.

Different kinds of calories and their effects

There are various sources of calories that you consume. A calorie chart would help understand which foods and beverages contain how many calories.

  • Carbohydrates

The two most important kinds of carbohydrates are known as sugars and starches. Sugars can be defined as simple carbs. Sugars are found in smaller units, and they release the energy directly into your bloodstream and at a fast pace. Starches on the other hand are complex carbohydrates. Starches are made of fibre and release a steadier flow, and at a much slower pace. Some of the examples of starch are potatoes, bread, cereals, pasta, and rice. The fibre that is present in complex carbs works as a cleanser of your body.

  • Proteins

Proteins can be defined as complicated and large substances. Proteins contain multiple small units that are known as amino acids. Your body breaks down proteins in an attempt to reuse amino acids. Some of the protein-rich food items are fish, eggs, dairy products, and meat.

  • Fats

Fats are one of the best providers of energy to your body. There are three varied kinds of fats known as unsaturated fats, saturated fats, and trans fats. Unsaturated fats are found in fish largely. These contain fatty acids that are beneficial for your health. Saturated fats are found in meat, butter, lard, cream, and cheese. Trans fats can be found in processed and margarine food items.
