EFFECT OF SUGAR ON INFLAMMATION


Inflammation is a response triggered by damage to living tissues (Encyclopedia Britannica, Inc, 2014), the inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury.

The injury can be cause by chemical agents, physical forces, living microbes or many other physiologic or pathologic stimuli that disturb the normal steady state as defined by Damjanov (2012), who insists that inflammation occurs only in multicellular organisms that are capable of mountaing a neurovascular and cellular response to injury.

Recent research suggests tha inflammation inside the body plays a role in the development of Type 2 Diabetes. In this condition, the body can’t produce enough insuline or the bodies can’t use the insuline adequately due of insuline resistence (Tierney, McPhee, & Papadakis, 2005).

In a normal condition, when the blood sugar rise rapidly, after some food, the pancreas secretes insulin whose primary purpose is to drive sugar into each cells where it is stored for energy. If the cells is full, it is rejected, them blood sugar rise again producing more insuline and the glucose converts to stored fat, as Dr Lundell (2012) explain, the extra sugar molecules attach to a variety of proteins that in turn injure the blood vassels wall and set off the inflammation.

In the other hand, inflammation is induced by chemical mediator produced by damage host cells, such as Cytokines (Beck, 2014) and others, the bolus of blood sugar that accompanies a meals or snack of highly refined carbohydrates like bread, white rice, French fries, sugar laden soda, increases levels of this inflammatory messenger (President & Fellows of Harvard College, 2007). Researchers discovered that in people with type 2 diabetes, cytokine levels are elevated inside fat tissue, causing low levels of abnormal inflammation that alter the action of insulin and contribute to development of the disease (Nazario, 2012) the body becomes less sensitive to insulin and the resulting insulin resistance also leads to inflammation. A vicious cycle can result, with more inflammation causing more insulin resistance and vice versa.

Spranger, et al.(2002) evaluated the effects of various inflamatory cytokines on the risk of type 2 diabetes and they concluded supporting the concept that subclinical activation of the immune system is involved in the pathogenesis of type 2 diabetes, demonstrating in their study that a specific pattern of cytokines was associated with an increased risk of type 2 diabetes, rather than isolated elevation of the respective cytokines.

Finally, although there is no clearly in the pathogenic mechanism, several studies demonstrating the association between elevated blood sugar levels, inflammation and diabetes mellitus, we are only in the beginning to understand the role of this form of internal inflammation may play in the development of chronic diseases like diabetes and vice versa.

HEART SURGEON SPEAKS OUT ON WHAT REALLY CAUSES HEART DISEASE


Dr Dwight Lundell said, “I freely admit to being wrong…..today is my day to right the wrong with medical and scientific fact….insisted heart diseased resulted from the simple fact of elevated blood cholesterol….the only accepted therapy was prescribing medications to lower cholesterol and diet that severely restricted fat intake….It is not working”.

I think this is a statement with a dramatic picturesque approach, before at all, cardiovascular disease can refer to differents heart or blood vessel problems, the term is often used to mean damage to your heart or blood vessels by atherosclerosis, a buildup of fatty plaques in your arteries, it buildup thickens and stiffens artery walls, which can inhibit blood flow through your arteries to your organs and tissues (Mayo Clinic Foundation, 2014).

Atherosclerosis is the most common cause of cardiovascular disease, but it can be caused by others correctable problems such as unhealthy diet, sedentary, obesity and smoking. Hyperlipidemia, included the high blood cholesterol, constitutes one of the most important risk factors for atherosclerosis (Damjanov, 2012) and cardiovascular diseases.

The discovery a few years ago that inflammation as concept, in the artery wall is the real cause of heart disease like Dr Lundell mentions,  is really true, but a long time ago, the medical community in spite of an incompletely understood the interaction between the critical cellular elements in the atherosclerotic lesion, postulated theories related to atherosclerosis and cells injury, for example Rokitansky in 1851, suggested that atherosclerosis begins in the intima with deposition of thrombus and its subsequent organization by the infiltration of fibroblasts and secondary lipid deposition, few years later in 1856, Virchow proposed that atherosclerosis start with lipid transudation into the arterial wall and its interaction with cellular and extracellular elements, causing intimal proliferation (Boudi, 2014). In the 1990s, Ross and Fuster postulated that vascular injury starts the atherosclerotic process. (Ross, Fuster, & Topol, 1996).

The above explained that we were not wrong, but we were finding explanations based on studies and investigations that were conducted.

Finally, with the knowledge that we have today, the concept a little clearer about the inflammation and potential precursors, I agree with Dr Lundell, what we can do is choose whole foods that our grandmother served and not the manufactured foods that we found in the grocery today, because eliminating inflammatory foods and adding essential nutrients from fresh unprocessed food, we can reverse the damage in our arteries.
