Diet has become one of the principal causes of the emerging diseases, especially the so-called Non-communicable Diseases (NCD’s) among the global population. Currently, most countries have experienced transient nutrition transition, owing to changes in lifestyle and the availability of dietary products. Globally, it seems most people have abandoned their traditional diet and adopted modern eating habits, which tend to favor the consumption of dietary fats, especially from animal products (Boushey, Coulston & Ferruzzi, 2012). In contrast, the highest percentage of the global population has reduced the consumption of a vegetarian diet such as vegetables and fruits; instead, most people have increased high-fat diet intake (WHO, 2003).
Surprisingly, the ultimate result for the transient nutrition transition among the global population is the unprecedented increase of mortality rates related to Non-communicable diseases such as cancer, cardiovascular diseases and diabetes.
In America, diet related diseases have become an immense public healthcare problem to the healthcare system because; diet related diseases have assumed upward trends. Currently, Non-communicable diseases have become the leading cause of deaths, in the United States of America (Hospedales, 2011). These trends can be attributed to the excessive consumption of animal dietary products because; biomedical research has identified the harmful effects of animal dietary products on human health. Animal dietary products have been found to cause numerous health problems to humans, although they provide essential nutritional requirements to the human body but, excessive consumption increases the risk of suffering from diet related diseases. On the other hand, vegetables and fruits have been found to be reliable remedies to Non-communicable diseases. Therefore, this essay will give an overview of the diet and disease correlation.
Currently, it has emerged that an individual’s health status is determined by the type of diet an individual consumes. The current trends of excessive consumption of animal dietary products explain the reason as to why Non-communicable diseases, commonly referred to as ‘lifestyle diseases’ have become the most prevalent among the American population. Nutritional research indicates that animal dietary products contain high amounts of unsaturated fats, which is believed to be the principal cause of health problems to most people (Boyle & Long, 2008). These fats are believed to lead to incidences of obesity, cardiovascular diseases, cancer and diabetes.

In America, obesity has become the most prevalent Non-communicable disease with more than half of the US population being obese. Recent epidemiological reports show that 35.9% of adults are obese, whereas, children aged 6-11 years and adolescents account for 18.0% and 18.4%, respectively. Further reports reveal that, in 2010, 12.1% of children aged between 2 to 5 years, in the US are obese (CDC, 2012). As a result, the US Healthcare system experiences an enormous burden from obesity.
Obesity refers to a health condition in which an individuals’ body weight exceeds the required healthy limits. In other words, individuals whose Body Mass Index exceeds 29.5 in value are considered to be obese. In general, obesity is believed to be caused by a transient change of lifestyle from physical activity to a sedentary lifestyle accompanied with excessive intake of carbohydrates and animal fats. It has been found that excessive intake of animal fats leads to the accumulation of fat in the body of an individual, which are stored in fat deposits, usually around the waist (Boushey, Coulston & Ferruzzi, 2012). These fats are hardly consumed for oxidative respiration to generate energy for physical activity and other biological functions in the body. As a result, fat tissues are stacked with fat layers, leading to a rapid weight increase of an individual. Continued intake of animal products, which are rich in fats, leads to excessive accumulation of fat deposits, hence an increase in one’s Body Mass Index value. Ordinarily, excessive accumulation of fats in the body is manifested by the rapid enlargement of the waistline.
In most cases, obese individuals experience difficulties in locomotion due to the excessive weight gain, leading to the malfunctioning of the leg joints and muscles. However, it is worth noting that, excessive weight gain among the obese people has been found to cause other health conditions. Some of the health conditions related to obesity diabetes and arthritis. Arthritis occurs due to the excessive accumulation of body weight, which burdens the leg joints during movement. In most case, bone cartilage lining the joints wear out, leading to increased friction between the bones and, this is manifested by pain within the knee joints during movement. Therefore, obesity causes the highest percentage of immobility among obese people.
On the other hand, animal fats increase the risk of diabetes among the obese people. Biomedical research reveals that, most animal dietary products contain high levels of unsaturated fats, which are not utilized in the body for respiratory activities; instead, they are deposited in the lipid bi-layer, which forms the cell membrane; thus, interfering with the functioning of the body cells. As a result, permeability of nutritional macromolecules such as glucose and proteins is adversely impaired, leading to the so-called glucose resistance by the body cells. As a result, glucose and other simple sugars accumulate in the blood stream leading to a condition referred to as hyperglycemia (high blood sugar), which in turn, leads to the onset of diabetes.
