Analysing your IQ

Discover the foods and nutrients that support optimal brain function. Learn about brain-healthy diets, supplements, and nutritional strategies.
The brain consumes 20% of your daily energy and requires specific nutrients to function optimally. Diet affects both short-term cognitive performance and long-term brain health.
Nutrients affect brain function through multiple pathways: omega-3 fatty acids support cell membrane health, antioxidants protect against oxidative stress, and B vitamins support energy metabolism and neurotransmitter synthesis.
The Mediterranean diet is associated with slower cognitive decline and reduced dementia risk. Omega-3 supplementation shows modest benefits for memory and processing speed. Severe deficiencies (iron, B12, iodine) significantly impair cognition.
Emphasize fish, olive oil, vegetables, nuts, and whole grains while limiting processed foods.
Eat fatty fish 2-3x weekly or consider algae-based omega-3 supplements.
Consume colorful vegetables and berries rich in polyphenols and flavonoids.
Get sufficient iron, zinc, B vitamins, and vitamin D through diet or supplementation.
Even mild dehydration impairs cognitive function. Drink water throughout the day.
Take an IQ test to measure your baseline before implementing these strategies.
Take IQ TestNo single food dramatically increases IQ, but a diet rich in fatty fish, vegetables, nuts, and whole grains supports optimal brain function. The Mediterranean diet has the strongest research support.
Most nootropics lack strong evidence. Omega-3 fatty acids and vitamin D (if deficient) have modest support. Focus on diet first before considering supplements.
Yes. Diets high in omega-3s, antioxidants, and low in processed foods are associated with better memory performance and slower cognitive decline.
