Research shows that the nutrients in food can have a significant positive impact on a person's cognitive abilities. Kogninit ability itself is a mental activity of the brain associated with the ability to think, speak, remember, and the creative power.
Cognitive disorders increasingly linked with the level of oxidative stress, a condition caused by excessive harmful molecules called free radicals or oxidants.
Free radicals are known to cause inflammation in the brain, so the presence of the antioxidant and anti-inflammatory compounds is very important to maintain brain health.
Sunflower seed
Sunflower seeds can be a snack rich in vitamin E. Studies show that intake of vitamin E may help prevent cognitive decline, especially in the elderly.
A sprinkling of sunflower seeds on the menu breakfast can help improve memory. In addition to being one of the richest sources of vitamin E, sunflower seeds are also abundant choline are also important in sharpening the memory.
Other foods that are also high in vitamin E are green leafy vegetables, vegetable oils, almonds, and avocados.
berries
Berries are rich in antioxidants such as blueberries, blackberries, and strawberries have been shown to improve memory and learning ability.
In addition, animal studies show that regularly eat berries have a good effect on brain signals involved in inflammation and cell death.
Thus playing a role in delaying the occurrence of brain disorders associated with age such as Alzheimer's disease and dementia.
tuna
Fatty fish such as tuna provides docosahexaenoic acid (DHA), a type of omega-3 important for brain development, and helps slow the aging process of the brain as we age.
In addition, as recommended by the FDA and EPA, the consumption of seafood is very important for pregnant or breastfeeding women because it helps the growth and brain development in children and even help improve IQ.
Research shows that when women of childbearing age consume 2-3 servings of fish per week, the baby can obtain IQ scores 2.6 points higher than pregnant women who do not eat fish.
Concord grape juice
A recent study published in the American Journal of Clinical Nutrition shows that drinking Concord grape juice every day is associated with cognitive benefits, the ability to think and remember.
Plant nutrients, or polyphenols contained in it are considered to have a prolonged impact on cognitive well-being.
Spinach
Spinach is rich in antioxidant lutein, which can protect the brain against cognitive decline. Researchers from Tufts University found that having a brain that are rich in lutein is associated with better cognitive abilities, including language skills, learning and memory.
Results of the Harvard Medical School study found that women who eat a lot of vegetables, especially green leafy vegetables such as spinach and romaine lettuce, including broccoli and cauliflower, experienced a slower rate of cognitive decline.
beet
Bit is a natural source of nitrate, which according to scientists at Wake Forest University can increase blood flow to the brain, thus improving mental health.
Researchers at the Translational Science Center found that drinking beetroot juice every day can help to increase blood flow to an area of the brain associated with dementia prevention.
Egg
Eggs, especially the yellow section, is the primary source of choline. Choline is one of forming acetylcholine, a neurotransmitter associated with the ability to store short-term information, like where you put the car keys.
If you are concerned about the levels of cholesterol in the yolk, the recent Dietary Guidelines for Americans (DGA) in 2015 to delete the daily limit of 300 mg cholesterol, so eating one egg yolk per day is fairly safe.
