6. Leafy Green Vegetables
Leafy greens such as spinach, kale, collard greens, and broccoli are packed with brain protective nutrients like vitamin K, lutein, folate, and beta-carotene.
How it helps:
These nutrients help slow cognitive decline and support neuron health. Vitamin K, in particular, plays a key role in forming sphingolipids fats essential for brain cell structure.
Scientific insight:
A study published in Neurology found that older adults who ate one or two servings of leafy greens daily had cognitive abilities comparable to those 11 years younger.
How to include:
Add greens to salads, soups, smoothies, or stir-fries. Steaming or lightly sautéing helps preserve their nutrients.
7. Eggs
Eggs are one of the best sources of choline, a nutrient crucial for the production of acetylcholine, a neurotransmitter involved in mood and memory regulation.
How it helps:
Choline supports brain development and enhances memory. Eggs also provide B vitamins like B6, B12, and folic acid, which help reduce homocysteine a compound linked to cognitive decline.
