You’ve probably heard that lutein and zeaxanthin are good for the eyes. These two major carotenoids found in the macula and retina are sometimes called xanthophylls or macular pigment. They function as antioxidants and also help protect tissues from phototoxic damage by filtering out some of the blue light.
The eye, and particularly the macula and retina, are almost constantly subjected to free radical generation and oxidative damage. Just as exposure to too much sunlight can damage the skin, so too can light damage the eyes. It is, thus, critical that you maintain your basic nutrients and especially antioxidants in the eye.
A study of macaque monkeys (with eyes similar to humans) showed that there was more zeaxanthin than lutein in the central fovea where vision is most clear. But, the concentration of zeaxanthin is reduced the further you get from the fovea and lutein dominates.
The macula has a yellow tint due to the presence of lutein, zeaxanthin and another xanthophyll called meso-zeaxanthin. It’s these pigments that help filter out or absorb some of the more damaging blue light to help protect the eye.
EMFs (electromagnetic fields) can penetrate buildings and the human body. Today, everyone is exposed to man-made, artificial, EMFs from electrical power lines, radio and TV broadcast towers, cell phones and cell towers, tablets, baby monitors, surveillance devices, Wi-Fi routers, utility meters, and even satellites. These sources bombard us with both low frequency and high frequency radio waves.
We are increasingly concerned about the myriad of EMFs we are exposed to every day. Radio frequency radiation produces biological effects at very low intensity levels. Damage does not require ionizing radiation to break molecular bonds. Significant biological effects occur at exposure levels much lower than current public safety levels.
Epigenetic changes that alter gene activation and expression are of increasing concern. Of particular interest is the effects EMFs have on young people, including the fetus, infant and young child.
Children exposed to electromagnetic radiation exhibit functional changes similar to autism and attention deficit hyperactivity disorder. Adolescents experience problems with memory, learning, attention, concentration, behavior problems and sleep quality.
Hydrogenated water helps reduce the oxidative stress that accelerates aging. If you are interested in slowing aging, reducing inflammation, and protecting yourself from many diseases and medical conditions, hydrogen water may be the key to your success.
Free radicals and other reactive oxygen species (ROS) are the result of normal enzymatic and nonenzymatic reactions in the human body. For example, stress, inflammation and exercise can create free radicals.
Free radicals can also be generated because of external influences such as
Exposure to ultraviolet rays
Oxidative stress due to excess free radicals progressively damage lipids, proteins, carbohydrates, RNA and DNA. This causes damage to cells and homeostatic disruption. The damage accumulates over time throughout the body.
Free radical damage is important because it manifests itself as disease and sickness. Free radical damage is associated with a number of conditions including premature aging, cancer, hypertension, heart diseases, stroke, arthritis, atherosclerosis, metabolic syndrome and diabetes.
Balance Between Reactive Oxygen Species and Antioxidants
Cannabis, or marijuana (Cannabis sativa) is known for its psychoactive properties and its illegal recreational use to get “high” or “stoned”. The main psychoactive chemical in cannabis is tetrahydrocannabinol, commonly known as THC. This was isolated in 1964. Another important component, nonpsychoactive cannabidiol (CBD), was identified in 1963. All together, there are more than 60 pharmacologically active compounds called “cannabinoids”.
In the 1980s the endoCannabinoid system was discovered. It is a complex neurotransmitter or signalling system consisting of receptors, endogenous ligands and enzymes that exists throughout the central nervous system (including the brain) as well as the peripheral nervous system.
This endocannabinoid system has been found to express elevated signalling in various neurodegererative diseases including Parkinson’s disease, Alzheimer’s disease, allergic encephalomyelitis and multiple sclerosis. The purpose of this activation seems to be to reduce neuronal hyperactiviety and local inflammation which could cause damage as well as to reduce tremors and spasticity. Continue reading →
