    Default Harmful Effects Of Junk Food

    Lack of energy

    Junk foods do not contain any nutrients that are beneficial to the human body. In most cases, these foods are filled with harmful carbohydrates, fats and cholesterol that do not provide any useful energy. As a result, somebody consuming junk food has reduced level of essential nutrients thereby causing weakness in the body.

    Poor Concentration

    One disadvantage of consuming junk food is that it contains high amount of oil and fat. As a result, human body finds this food difficult to digest and needs to spend high amount of blood and enzymes. When a person consumes junk food in excess, a major portion of blood in the body is diverted to the intestine. As a result, the person feels drowsy and suffers with reduced concentration.

    Heart Diseases

    Junk foods have been identified as a major cause of heart diseases including myocardial infraction, cardiac arrest and atherosclerosis. This is due to the fact that junk food contains excessive amount of low-density lipoproteins and cholesterol that get deposited on the inner linings of blood vessels. This result in formation of plaques and the heart is required to put an extra effort for pumping blood through the arteries. Presence of fat in the blood also causes reduced oxygen levels. Another harmful factor present in junk foods is excess concentration of sugars and salt. Excessive concentration of sodium ions causes an increased heart blood pressure.

    Liver Failure

    Even liver gets damaged due to presence of ingredients such as fat, cholesterol and salt inside the junk foods.

    Diabetes

    Junk foods also cause damage to the pancreas resulting in insulin-dependant diabetes mellitus (IDDM).
