How Sugar Damages Your Brain
An article published in the journal Nature claimed that sugar is a toxic substance that should be regulated like alcohol and tobacco. This conclusion was based on many studies conducted on the effects of sugar in the body including how it impairs several brain functions.
2How Sugar Affects the Brain-Derived Neurotrophic Factor
Research shows that frequent consumption of large amounts of sugary foods, specifically those that contain “added sugar” (refined sugar white or brown) can lead to reduced production of BDNF.
BDNF or Brain-Derived Neurotrophic Factor is a chemical in the brain that plays a crucial role in the development of neurons and brain tissues that are responsible for forming new memories.
Without BDNF, an individual will have increased difficulty storing memories and learning new things. Low levels of BDNF are commonly found among people who have impaired glucose metabolism, particularly those who have been diagnosed with diabetes.
If a person continues to consume foods that contain added sugar their BDNF will also continue to decrease, which will contribute to the worsening of insulin resistance.
This means the person will more likely to suffer from type 2 diabetes and other illnesses that are linked to metabolic syndrome. Unfortunately, the destructive cycle of high sugar consumption and lowered levels of BDNF are difficult if not impossible to reverse.
