Lutein, found in dark green leafy vegetables, is an antioxidant that supports eye and brain health.

• Lutein is a potent antioxidant in the retina and brain, correlating with cognitive function.
• It has anti-inflammatory properties and is linked to visual and cognitive health.

Observational studies suggest a link between lutein intake, brain function, and the reduction of dementia risk.

• Higher lutein levels in the brain are associated with better cognitive abilities.
• The cause and effect relationship is confirmed through testing.

Supplementation with lutein and zeaxanthin can improve eye health and possibly prevent age-related vision loss.

• Ophthalmologists recommend increasing lutein intake to prevent and treat macular degeneration.
• Spinach supplementation boosts macular pigment and can improve visual processing speed.

Both older and younger adults can experience cognitive improvements by increasing their intake of lutein and zeaxanthin.

• Adults showed cognitive improvements from consuming lutein-rich kale or spinach.
• Young adults also showed enhanced brain function, memory, and attention.

Whole foods may be more beneficial than supplements for improving cognition and preventing diseases.

• Avocado consumption showed cognitive improvement, similar to potatoes and chickpeas.
• Whole foods like dark green leafies might be more effective than pigment supplements.

Preventive dietary approaches focusing on reducing oxidation and inflammation are essential for health.

• Prevention is key in diseases like Alzheimer's and macular degeneration.
• Early stages of reducing oxidation and inflammation may be the most promising approach.
