A New Look at Digestion: Light, Eyes, and Insulin
Introduction:
Digestion does not begin in the mouth. This is outdated 20th century nonsense. In fact, digestion begins when light bounces off food and hits your retina. Your retina is part of your brain/CNS, specifically the diencephalon. If you think digestion starts in the mouth, you are scientifically behind.
Digestion begins in the eyes
The key to this understanding is the ocular insulin reflex. Light induces photooxidation, which stimulates hypoxia in the retina, and this stimulates insulin production directly in the retina. Most importantly, the discovery of insulin production in the central nervous system (CNS) has opened up many possibilities for determining new functions of insulin in tissues outside the pancreas.Insulin in the central nervous system (CNS)
The discovery of insulin production in the CNS opened new possibilities for determining new functions of insulin in tissues outside the pancreas (Devaskar et al. 1994; Havrankova et al. 1978; Kovacs and Hajnal 2009). For example, its neurotrophic function promotes neuronal development and survival after ischemic brain injury (Voll and Auer 1991; Valenciano et al. 2006; Hui et al. 2005).Local synthesis of insulin in the brain
Detection of the presence of insulin immunoreaction in fetal, neonatal and adult brains did not distinguish between insulin of pancreatic origin that crossed the blood-brain barrier and synthesis in the central and peripheral nervous system. It was not until the use of the polymerase chain reaction that it was possible to clearly distinguish that the processing of the insulin protein takes place locally in these tissues, and not at distant sites where the secreted protein crossed the blood-brain barrier and translocated to the brain (Devaskar et al. 1994; Murakami-Kawaguchi et al. 2014; Deltour et al. 1993).Common nutrition gurus often just repeat known information. However, none of these things have an effect on chronic diseases.
Insulin and brain function
They never talk about the real heart of the problem - how light and insulin are linked through the CNS. Although insulin is involved in glucose metabolism, the brain has long been considered an insulin-insensitive organ. It is now well established in the literature that insulin facilitates critical brain functions such as metabolism, cognition, and motivated behavior in the CNS, while also acting as a potent mitogenic and neurotrophic factor (Ferrario and Reagan 2018; Mielke and Wang 2005; Abbott, Wells, and Fallon 1999 ; Wu et al. 2004; Naia et al. 2016).Effect of light on health
Understanding the relationship between light, insulin, and the CNS has far-reaching implications for our health. The quality and type of lighting can affect our insulin production and thus our overall health and cognitive function. People with insulin problems cannot make dopamine or melatonin very well and are easy to manipulate because they are not independent thinkers.Conclusion:
This new perspective on digestion forces us to rethink many aspects of our understanding of the human body. The connection between light, eyes, insulin and the CNS opens up new possibilities in the field of research and treatment of chronic diseases. Clearly, we need more decentralized scientific research in this area. This new understanding can lead to innovative approaches in medicine, nutrition and lifestyle that can fundamentally improve our health and quality of life. It's time to open our eyes to new knowledge about how our bodies work and rethink traditional views on nutrition and health. Increase your knowledge with decentralized science.
