Kale, collard greens, spinach, and broccoli are good sources of vitamin E and folate, Morris says.
For example, one cup of raw spinach has 15% of your daily intake of vitamin E, and 1/2 a cup of cooked spinach has 25% of your daily intake.
Exactly how folate may protect the brain is unclear, but it may be by lowering levels of an amino acid known as homocysteine in the blood. High levels of homocysteine may trigger the death of nerve cells in the brain, but folic acid helps break down homocysteine levels.
High homocysteine levels have also been linked to an increased risk for heart disease.
