According to Mayo Clinic, USA, “immune system is responsible for helping to eliminate invaders (antigens) such as infectious organisms”.

Merck Manuals  also says “The role of the immune system — a collection of structures and processes within the body — is to protect against disease or other potentially damaging foreign bodies. When functioning properly, the immune system identifies a variety of threats, including viruses, bacteria and parasites, and distinguishes them from the body’s own healthy tissue”.

There is lots of debate about the possibility of boosting the immune system of the body. According to the highly respected and regarded medical school “Your first line of defense is to choose a healthy lifestyle. Following general good-health guidelines is the single best step you can take toward keeping your immune system strong and healthy. Every part of your body, including your immune system, functions better when protected from environmental assaults and bolstered by healthy-living strategies”.

Away from theoretical rhetoric, the practical testimonies of those of us who have chosen a healthy diet and lifestyle is but a clear indication that you can help your immune system to be stronger and function better. This simple perspective has been used for tens of people to improve their health for better.

There is absolutely no complexity in boosting immune system, only simple little steps to making your body healthier and better. Let us examine them.


The very first step to address a problem is to first identify the root cause of the problem. Certain foods and environmental factors affect the functioning of immune system. Attempts will be made to summarise these foods, drinks and factors as it is a broad topic on its own.

  • Refined Sugar and Salt: These have been labelled a major culprit in affecting immune system. Cut down intake of sugar and you would have made a good step towards better health. Not only should you avoid using white sugar, you should also avoid it in sugar drinks and foods. Table salt causes the blood pressure to rise rapidly because the blood is attempting to move the toxic elements rapidly away from the heart. This is why doctors will often tell people with high blood pressure to stop or reduce intake of salt. Table salt contains more than Sodium Chloride, they also contain additives that are designed to make it more free-flowing. Ferrocyanide, talc, and silica aluminate are commonly included.
  • Carbonated Water/Soft Drinks: Soft drinks are not actually soft on our immune system. They may taste nice in the mouth but are not nice in the body. They are not in any way friendly to our immune systems. A common concern with carbonated beverages/drinks is the acidity levels and the risk of calcium and magnesium loss from bones due to change in the body’s pH levels. In order words carbonated drinks under any guise will increase the acidity of the body. Unfortunately, lots of people are even addicted to taking these drinks on a daily basis. You can practically do without them, it is an hard choice you need to make.
  • Processed and Canned Foods: Processed foods are foods that have been compromised by the addition of hormones, additives, preservatives, unnatural genetic material or other chemical or heat treatments that alter or destroy the natural healthy enzymes, fatty acids, vitamins and minerals. Processed foods are implicated in a wide range of health problems. Meanwhile, canned foods have been said to be harmful to the body due to the Bisphenol (BPA for short) which is used in coating the container.
  • Smoke/Fumes: not only does smoke irritate, it is very harmful. It is another major immune destroyer and unfortunately we all are exposed to this on a daily basis. Carbon monoxide (CO) can cause harmful health effects by reducing oxygen delivery to the body’s organs and tissues. At extremely high levels, CO can cause death (as we sometimes hear in the news). Exposure to CO can reduce the oxygen-carrying capacity of the blood.
  • Lack of Good Sleep: It is an old wives’ tale that if you don’t sleep well, you will get sick, and there is some experimental data that shows this is true. Our bodies go through a repair cycle during sleep and where you don’t get adequate sleep, you deny the body of repairs.
