SOURCES OF CALORIES

A calorie is a unit of measurement, but it does not measure unit of length. It is a unit of energy. Say for example, a certain food contains 100 calories, it’s a description of how much energy your body can get from eating that particular food. Calories are not bad for our body, in fact human body badly needs calories to get enough amount of energy, but eating too many calories and not burning them could be resulted to weight gain. There are foods containing more calories especially junk foods and fatty foods, but vegetables and fruits contained few calories.

Our body should have balanced activities to moderate weight gain. If you consumed foods with high calories, it is good to burn them with physical activities. But it is not recommended by health experts to burn all the calories your body accumulates, because our lungs and heart need them also to function well. Watching TV is not the most ideal hobby because it makes the body rest and the excess calories will stuck up in the muscles.

Here are the four sources of calories:

ALCOHOL
Among the four sources of calories, alcohol provides higher caloric content, but these calories have no essential vitamins and minerals attached. Alcohol-contained foods is converted into fat, unable to digest carefully, this will be stored in the body, which sometimes triggers obesity. But when taken in moderation, alcohol-contained foods may be beneficial as it increases the level of high density lipoproteins in the body. Too much alcohol intake has bad effect to over all health as this may contribute to diseases such as multiple liver failure, brain damage, weakening of the heart muscles and premature aging, it can also increased the risk of all forms of cancer. Red wine, according to some health studies, shows some beneficial effects because of the presence of resveratrol in grape skin, an antioxidant that helps slow cardiovascular diseases like hardening of the artery, but this should also be taken in moderation.

CARBOHYDRATES
Carbohydrates when broken down in the digestive system will form glucose, which is the essential source of energy and tissue protein. Our central nervous system-the brain and the spinal cord-depends on glucose for energy requirements, thus without carbohydrates, our body slows its alertness and dropped down the level of normal functioning. Carbohydrates rich foods are whole grain cereals, brown rice, bread, pasta, corn, beans, peas, potatoes, fruits, vegetables and meat products. These foods when taken are slowly broken down into glucose and absorbed by the body. But carbohydrates should be aided by soluble fibers to aid the proper digestion process. Soluble fibers include apples, strawberries, oats, citrus and other fruits. It will help support the body by slowing down the process of glucose thereby lowering cholesterol level. Insoluble fibers in leafy vegetables, whole grain products help prevent constipation.
FATS
Fats can be classified as saturated, monounsaturated, polyunsaturated. Sources of saturated fats are eggs, milk and meat, saturated fats also contain cholesterol, which is manufactured by the liver and small intestine, by this reason, the body does not need cholesterol from food sources. When we consumed too much saturated fats, it will tend to increase lipoprotein (often called bad cholesterol) in our blood stream, this will leave additional coating of cholesterol in the artery walls and slowly clog the arteries. The narrowing of the arteries makes the heart to pump harder and refused to spread the supply of blood into other parts of the body, this activity leads to the tiring of the muscle of the hearts that causes heart disease and hypertension, other various diseases may drawn out also including obesity and cancer.

Monounsaturated and polyunsaturated fats (also called good cholesterol) can be obtained from vegetable oils, nuts, olives and avocados. They are essential fats that needed our body to store energy and renew body cells. Fats are the most important component sources of energy our body needed. It is important for the absorption of fat-soluble foods and supplements including Vitamins A, D, E and K, with out fats, these vitamins could not be absorbed fully by our body. Fats are important protectors of the human body from extreme temperatures of heat and cold.

PROTEIN
Proteins composed of complex nitrogen-containing compounds that build and repair body tissue. Proteins also form antibodies, enzyme, hemoglobin and hormones. Proteins also are made up of essential fatty acids which can be obtained from milk, eggs, meat and fish. Deficiency of protein can hamper growth developments and prevent the body to fight infections. But too much protein can endanger body’s functioning, because it will force the kidney to eliminate the excessive waste products.
