Advanced glycation end products, commonly known as Advanced Glycation End Products Market , are a complex and widespread result of sugar and fat metabolism in our body. The formation and accumulation of AGEs has serious health implications and is linked to several chronic diseases like diabetes, kidney failure, cardiovascular disease and Alzheimer’s. In this article, we will explore what AGEs are, how they are formed, their effects on our health and ways to prevent or reduce levels of AGEs in our body.
What are AGEs?
A glycation reaction occurs when a sugar molecule, such as glucose, reacts with a protein or lipid, without the regulating effects of an enzyme. This reaction occurs spontaneously in our body, but is sped up in conditions of high blood glucose levels such as in diabetes. Over time, the initial reaction continues through a series of chemical and oxidative rearrangements, and produces a diverse class of advanced and stable molecules known as AGEs. The most abundant and well-studied AGE is NƐ-carboxymethyllysine or CML. Some other common types of AGEs include pentosidine, pyrraline and glyoxal-lysyl dimer (GOLD).
AGE Accumulation and Its Detrimental Effects
AGEs are formed continuously in our tissues and cells but are usually effectively cleared by the kidneys, macrophages and other mechanisms. However, in conditions where their formation is elevated like diabetes, or renal function is compromised, there occurs an accumulation of AGEs in tissues over years or decades. The accumulated AGEs can bind to cell-surface receptors like RAGE, activating oxidative stress and inflammatory pathways. This leads to increased production of reactive oxygen species and pro-inflammatory cytokines. At the tissue level, it results in the thickening of arterial walls, damage to pancreatic beta cells, and increased stiffness of organs and tissues. All of these changes contribute to the pathology and progression of age-related chronic diseases.
AGEs and Diabetes Complications
Diabetes is a major cause and consequence of elevated AGE levels in the body. High levels of glucose in diabetes act as a precursor fueling AGE formation. At the same time, AGE accumulation exacerbates diabetes-related tissue and organ damage through chronic inflammation. For example, AGEs promote fibrosis and stiffness in small blood vessels, contributing significantly to kidney failure, retinal damage and foot ulcers in diabetes. They also appear to be responsible for pancreatic cell dysfunction and impaired insulin secretion over time. Research indicates that reducing AGE levels could aid in preventing or slowing the progression of diabetes complications.
AGEs in Other Chronic Diseases
The link between AGEs and cardiovascular disease is firmly established now. AGE accumulation in arteries hardens and stiffens them, reduces elasticity and promotes atherosclerosis. This increases the risks of heart attack, stroke and peripheral artery disease. AGEs have also been implicated in Alzheimer’s disease pathology. Markedly elevated levels of AGEs are found in the brains of Alzheimer’s patients. AGEs may contribute to amyloid-beta plaque formation and tau protein tangles, mechanisms implicated in neurodegeneration. Researchers are also exploring the role of AGEs in other age-related conditions like kidney disease, osteoarthritis and macular degeneration.
Reducing AGE Intake and Accumulation
Given their established role in accelerating chronic disease, it is important to reduce AGE levels. Diet is a major contributor to internal AGE burden, and eating thermally processed or browned foods like roasted/grilled meats and baked goods introduces many food-derived AGEs to our system. Fruits and vegetables, on the other hand, naturally contain very few food-derived AGEs. It is best to limit thermally processed foods in favor of raw, boiled or steamed options. Maintaining healthy blood glucose control through diet and exercise can also keep AGE formation within normal limits. Adequate hydration, nutraceuticals like aminoguanidine and carnosine, and plant compounds like quercetin also show promise in inhibiting AGE formation and accumulation.
Conclusion
In conclusion, Advanced Glycation End Products Market are metabolic byproducts that challenge our health in subtle yet impactful ways. By understanding their mode of formation and action, we can implement lifestyle strategies to reduce AGE accumulation throughout our lifetime. This may help offset the effects of natural aging and lower disease risks, especially in conditions of elevated glucose levels. More research is still needed, but lowering AGE levels is an achievable dietary and lifestyle intervention already backed by considerable scientific evidence.
