The needs of a significant part of the population are:Improves brain health, focus, and focus。After all, the current society is a "brain" society, and staying up late, working at high intensity, and thinking will consume brain cells. But most people obviously don't use their brains so seriously, so how should they take care of their brain health? Here are 6 recommended foods that have been shown to promote brain health and that you can add to your menu!
1. Fish
Rich in omega-3 fatty acids, especially DHA and EPA, which are essential for the health of the nervous system, can help improve cognitive function and prevent neurodegeneration. 2. Berries and fruits
Including blueberries, it has a potential protective effect against age-related neurodegenerative diseases and is able to improve motor and cognitive function. 
For example, a randomized, double-blind, placebo-controlled trial found that participants who consumed blueberries demonstrated improved executive function, enhanced short-term memory, and faster reaction times. This suggests that a daily intake of blueberries may help improve cognitive and cardiovascular health. In another study, blueberry supplementation was shown to enhance motor and memory performance in older animals. This study suggests that blueberries may have neuroprotective effects against neurodegenerative diseases3. Nuts
For example, walnuts, almonds, etc., contain brain-strengthening vitamin E, omega-3 and antioxidants.
Daily intake of nuts has been shown to benefit blood flow in the brain in older adults and improve verbal memory.
Other studies have found that eating nuts, such as walnuts, five times a week can have a positive effect on cognitive function. 
The above study also highlighted the benefits of walnuts, which are rich in polyunsaturated fatty acids, especially omega-3 fatty acids, which are essential for maintaining brain function. 4. Sea vegetables
For example, kelp is rich in linoleic acid, lecithin and other nutrients, which play an important role in brain development. 5. Dark chocolate and cocoa
Contains cocoa polyphenols that help improve concentration and memory, while also boosting mood. 
6. Eggs
Ranked last, but the most cost-effective and direct means, eggs are excellent for choline, which is an important nutrient for maintaining brain health.
Choline is essential for brain development, nerve conduction, and memory function.
Studies have shown that choline has a positive effect on cognitive function and brain health. Da Han talks about health
