Nutrition for a Healthy Immune System As technology advances, so does our knowledge of nutrition. However, despite this increase in knowledge, we are becoming one of the unhealthiest generations in history. Nutrition and the immune system are an integral part of overall stress management and should be considered as such. The Western medical approach of treating the problem with medication does not truly cure the underlying problem. One of the ideals of holistic stress management is homeostasis between the four aspects of humanity. Without a healthy nutritional balance, a human being cannot have a healthy immune system, which can lead to impaired homeostasis of the human body. Nutrition is the stuff the human body needs to survive. The essential nutrients that the human body needs are proteins, carbohydrates, fats, fiber, vitamins, minerals and water. Nutrients can be divided into two categories: large (macronutrients) and small (micronutrients). Important nutrients include fats, carbohydrates and proteins, while smaller nutrients that the human body also needs, but in smaller quantities, are minerals, fiber and vitamins (Weil, 2000). There are countless types of foods that the human body can process healthily. However, as technology advances in today's world, many foods lack the nutritional value that the human body needs to lead a healthy existence. Joe Esposito, a world-renowned nutritionist, coined the phrase “Standard American Diet” or abbreviated to SAD. This diet, composed of the “7 Deadly Foods”, are the most consumed foods in today's society: alcohol, artificial sweeteners, coffee, dairy products, fried foods, refined sugar and salt (Esposito, 2013). This system is essential for the proper functioning of the human body. The immune system is responsible for fighting infections and diseases. A healthy immune system requires a balance of nutrients, including vitamins A, C, D, and E, as well as minerals like zinc and selenium (Lamas, Marti, & Martinez, 2002). Obesity can also impair the immune system, leading to a higher risk of infections and diseases (Liddament, Brown, Schumacher, & Harris, 2004). In conclusion, nutrition is an essential aspect of a healthy immune system. A balanced diet including essential nutrients is necessary for the proper functioning of the human body. The Western medical approach of treating the problem with medication does not truly cure the underlying problem. Holistic stress management, including a healthy diet, is essential to maintaining homeostasis between all four aspects of humanity..
