Although women tend to live longer than men, they have more vulnerability to specific degenerative diseases such as autoimmune disease and dementia. This vulnerability can be because women store vitamins and minerals in their body fat as a reserve for pregnancy. This pregnancy reserve means fewer vitamins and minerals are available for the retina and brain, thus increasing a woman’s vulnerability.
Recent research indicates that there is a powerful way in which women can safeguard against this vulnerability. The new research shows that two carotenoids, lutein and zeaxanthin can act as antioxidants and improve central nervous system degeneration.
Antioxidants neutralize free radicals (molecules that damage cells) and minimize oxidation (the damage done by these free radicals to the cells).
By increasing their intake of lutein and zeaxanthin, women can take a proactive approach and protect against their vulnerability.
10 mg of lutein and 2 mg of zeaxanthin appear to be effective for good eye health in studies, but further research is needed to identify the optimal dosage for health.
The Institute of Functional Medicine recommends eating two portions of food (50g per portion) from the following colors daily – red, orange, yellow, green, white/tan, and blue/purple. Since lutein and zeaxanthin are naturally present in many fruits and vegetables, focus on fruit and vegetables for these.
Aiming to comply with this would naturally optimize your levels.
