Brain Health and Nutrition

Family sharing a meal. Nutrition is crucial for brain healthThe brain and eyes are intimately connected, and the nutrients essential for eye health are the same as for brain health. A retinal scan can detect the early onset of Alzheimer’s Disease, Parkinson’s Disease, and Multiple Sclerosis before symptoms appear.

Numerous studies have shown that dietary factors help prevent brain and eye disease. They have a critical effect on neuronal function and synaptic plasticity. Recent findings have shed light on key processes through which nutrition influences brain health and cognitive performance. Alongside lifestyle factors like physical activity, what we eat has played a significant part in the development of our mental abilities and the evolution of the human brain.

Cardiovascular Disease and Eye Health

heart affects eye diseaseThe link between cardiovascular disease and eye health may not be obvious. However, the eyes are made from nutrients. A large body of research shows how important nutrition is for eye health. Maintaining healthy vision depends on whether the eyes and visual system are properly nourished. Cardiovascular disease, including high blood pressure and atherosclerosis, can affect the flow of essential nutrients and oxygen to the eyes. Poor circulation to the eyes can cause damage to the retina’s tiny blood vessels, with potentially sight-threatening consequences. Cardiovascular disease can often be identified through retinal scans well before the disease is detectable through traditional tests. Continue reading “Cardiovascular Disease and Eye Health”

Antioxidants, Eye Disease and Oxidative Stress

antioxidant foodsThe links between antioxidants and vision health are strong. Antioxidants are the antidote to oxidization. Normal metabolism creates free radicals. These are atoms that lack an electron. Free radicals roam about the body, scavenging electrons and stealing electrons from healthy cells.  This results in permanent damage to these afflicted cells which ultimately can result in disease. Significant research has shown that antioxidants protect against this cellular damage and are essential for maintaining health. The eye is especially vulnerable to free radical damage. Therefore, providing the body with sufficient antioxidants Continue reading “Antioxidants, Eye Disease and Oxidative Stress”

Opposite Vitamin A Recommendations for Stargardt’s Disease vs Retinitis Pigmentosa

vitamin a beta carotene foodsStargardt’s Disease and Retinitis Pigmentosa are genetic eye diseases that involve the metabolism of vitamin A. However vitamin A has a different impact on the course of each disease. A recent study[1. BMC Ophthalmol. 2016; 16: 13. “Dietary profile of patients with Stargardt’s disease and Retinitis Pigmentosa: is there a role for a nutritional approach?” by Francesco Sofi et. al.] examined the total intake of vitamin A in both types of patients. It found that:

Philippines’ GMO Golden Rice with Beta-Carotene Sparks Controversy

Controversy over GMO “Golden Rice”

A variety of rice genetically modified to contain beta-carotene awaits approval in the Philippines. Supporters claim the rice could be an answer to the widespread Vitamin A deficiency in the country. They hope to see the “Golden Rice” in fields within the year, after it passes biosafety tests.

Beta-carotene is processed by the body and converted into Vitamin A. Vitamin A deficiencies lower immunity and can lead to blindness. Insufficient intake of this vitamin has been an ongoing problem in the Philippines, with Continue reading “Philippines’ GMO Golden Rice with Beta-Carotene Sparks Controversy”
