Calorie is a unit for measuring a quantity of heat; the amount of heat needed to raise the temperature of a gram of water by one degree Celsius. But here it refers to the energy we get from food. The word Calorie is also known as ‘kilocalorie’. A unit for measuring how much energy a food will produce. All foods provide us with energy which helps us maintain a stable body temperature and also perform day-to-day activities such as to move, read, exercise, and play. Foods and liquids like milk, juices, alcohols provide us energy, this energy supplied by food is measured in calories.
Balanced diet: A diet that contains the required amount of carbohydrates, protein, fats minerals and vitamins with enough of water is called a balanced diet. A balanced diet is one that is directly in proportion to a successful excessive weight loss. Choose the best of foods to build a balanced diet and a better life for yourself and your family.
Healthy diet: The aim of healthy eating is to get a balanced diet. A healthy diet in other words is in fact a balanced diet that includes vitamins and minerals; food that provides enough of fibre, important for a healthy digestive system and at the same time that also lowers cholesterol levels in blood.
As you very well know there are five basic groups of nutrients: Protein carbohydrate, vitamins, minerals, and fat and enough of liquid diet including water.
PROTEINS: Proteins are important for repair maintenance and growth of cells. Eggs, milk and milk products, beans, nuts, fish and meat are few food products rich in protein. If a person does not get enough of protein in his diet to make up for the natural breakdown of body tissues, some of the less vital protein tissues in the body such as the muscles, are broken down to maintain such vital organs as the heart and kidneys. Bread and other cereals like rice; oats, barley, peas, and beans are sufficient to provide plenty of proteins but on the other hand meat, fish, eggs, milk and cheese for that reason are all time favorites. Infection of any type in the body, broken bones, burns, excessive workout and the stern of surgery all lead to protein loss.
CARBOHYDRATE: Carbohydrate is an important source of energy. This is a substance such as sugar or starch that consists of carbon, hydrogen and oxygen. Carbohydrates in food provide the body with energy and heat. Foods such as bread, potatoes, and rice contain a lot of carbohydrate. It is basically a collective term for Cellulose, Starches, and Sugars.
Cellulose: Human beings do not digest cellulose neither it is a source of energy. Cellulose is required in diet because it is an important form of fibre and so promotes regular bowel movement [an act of emptying waste material from the human body, i.e. to go to the toilet] but at the same time remains undigested in the intestines.
Starches: Potatoes wheat and rice are rich in starch. The starch in food is further broken down and absorbed into the blood as glucose, a type of sugar.
Sugar: This is a sweet substance, used in cooking or to make puddings, tea, coffee, etc, sweeter. This is often in the form of white or brown crystals, such as caster sugar, icing sugar, granulated sugar, brown sugar made from the juices that are found naturally in various plants, such as sugar cane, sugar beet, and various other fruits. The main sugar in humans diet is sucrose. Sucrose is obtained from diet rich in sugar and its forms. Most of it is obtained from honey, jams, biscuits, cakes, tea, coffee and sweets.
Carbohydrates are further separated into two forms: Complex carbohydrate:
Complex carbohydrate is a better source of energy; simultaneously, a fibre rich diet, which is important for a healthy digestive system and lowers level of cholesterol in the blood.
Roti, rice, bread, potato, cereals, noodles, are all complex form of carbohydrates. Basically, sugar in foods such as fruits, chocolates, biscuits, and ice- creams, soft drinks are all simple form of carbohydrates.
