Iron Supplementation Improves Cognitive Function
April 2012 It is estimated that 25% of the world’s population, and approximately 50% of pre-school children worldwide have anaemia. 50% of anaemia cases are due to iron deficiency. Studies have shown that iron deficiency in infancy is related to poorer cognition in childhood. Iron is an essential mineral that plays key function in [...]
Korean Ginseng Helps to Enhance Cognitive performance
April 2012 Korean Ginseng (Panax Ginseng) is an adaptogenic herb that has been used as potent energy tonic for thousands of years in Traditional Chinese Medicine. Modern clinical study has provided scientific evidence on its benefit in enhancing cognitive performance. Although we do not yet fully understand the mechanism for many of Ginseng’s medicinal [...]
Dietary Antioxidants reduce the risk of ARMD
Age-related macular degeneration (AMD) is the leading cause of severe visual loss in individuals over 50 years of age. Previous studies suggest that high intakes of oily fish and antioxidant nutrients have been associated with a protective effect against AMD. The Rotterdam Study is a prospective cohort study ongoing since 1990 in the city of [...]
Compound From Olive Fruit Shows Heart Health Potential
A new study from Spain discusses the heart health potential of hydroxytyrosol, an olive extract possibly effective at reducing levels of oxidized LDL cholesterol. In a recent study, supplementing with hydroxytyrosol – a polyphenolic compound extracted from olives – correlated with higher activity levels of the enzyme arylesterase, an antioxidant biomarker, and lower levels of [...]
Dietary supplement use in the prevention of age-related macular degeneration progression
26 May 2011 Age-related macular degeneration (AMD) is the leading cause of visual impairment and blindness in the developed world among people aged 65 years or older. The Age-Related Eye Disease Study Group (AREDS) has found that high-dose vitamin supplementation may have a role in preventing the progression of Category 3 and 4 age-related maculopathy. [...]
Lutein and Zeaxanthin May Improve Visual Performance And Reduce the Effects of Glare
Healthy subjects with an average age of 23.9 were assigned to receive daily supplements of lutein (10 mg) and zeaxanthin (2 mg) for six months. The subjects’ eyes were then tested for the effects of glare as experienced in everyday situations, including being outdoors on bright days, lengthy sessions of looking at a computer monitor, [...]
Decreased antioxidant levels increase risk of age-related macular degeneration with exposure to sunlight
The journal Archives of Ophthalmology recently reported that having reduced plasma antioxidant levels and increased exposure to sunlight increases the risk of neovascular, or advanced age-related macular degeneration (AMD). In a recent study (titled the European Eye Study), over 4,400 participants over age 65 were analyzed for the presence of macular degeneration. Their blood plasma [...]
Vitamin C and E Supplements Lower Diabetic Retinopathy Risk
Diabetic retinopathy is a leading cause of blindness. It occurs when diabetes damages tiny blood vessels inside the retina (the light-sensitive tissue at the back of the eye). There may be an association between the use of vitamin C and E supplements and a reduced risk of diabetic retinopathy. A study published in the American [...]
High glycemic index diets increase the risk of age-related macular degeneration
Several dietary factors are known to be risk factors for age-related macular degeneration (AMD), the leading cause of blindness among persons over 65. New research indicates that high-glycemic-index diets may be a risk factor for early AMD and potential visual loss later in life. A new study published in the American Journal of Clinical Nutrition [...]
Oily fish intake and dietary omega-3 may improve eye health
According to new research, eating one portion per week of fish rich in omega-3 fatty acids may reduce the risk of age-related macular degeneration (AMD) by over 50 percent. Fish intake, the major source of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), may reduce the risk of age-related macular degeneration (AMD). There are two types [...]
