processed foods lead to metabolic syndrome

This is defined as a condition in which several risk factors that can lead to several heart diseases and type 2 diabetes are grouped under one category. For instance, shooting up of the blood glucose level that needs insulin to metabolize. The risk factors that contribute to this syndrome are-

  • Increased waistline with additional weight on the stomach
  • High level of triglycerides
  • Low healthy cholesterol levels
  • Elevated blood pressure
  • High level of fasting blood glucose

Sugar, which is a form of carbohydrates, is the fuel that drives the body. The number of sugars found in processed foods is very high. This is the primary factor that contributes to metabolic syndrome. When you consume these processed foods in large quantities, not all of them are used for the production of energy. The extra calories get stored in the body as fat.

Seven additives have been identified- glucose, salt, emulsifiers, organic solvents, gluten, microbial transglutaminase, and nanoparticles- are commonly used in processed food products which can lead to an autoimmune disease. These additives damage the tight junctions between epithelial cells (special cells that protect the intestinal tract). This destroys the defense barrier the body puts up against harmful toxins, bacteria, and other harmful antigens. This increases the chances of autoimmune diseases. 


  • Colorectal Cancer
