【推荐3】6 Best Foods To Boost Brain Power and Improve Memory

Number 1 — Legumes

Legumes are an excellent source of complex carbohydrates! These complex carbohydrates are also mixed with fiber that slow down absorption, providing a steady supply of glucose (葡萄糖) to the brain without the risks of sugar spikes associated with many other sugar sources. Legumes are also rich in folate — a B vitamin critical to brain function!

Number 2 — Mint

Mint is a good source of vitamin A and vitamin C. Vitamin A can help boost learning skills and increase brain plasticity, while vitamin C is said to protect against cognitive decline. According to studies, even the scent of mint affects brain functioning by boosting alertness and memory. It also helps improve basic clerical skills, such as typing and memorization.

Number 3 — Broccoli

It’s rich in calcium, vitamin C, B vitamins, beta-carotene, iron, fiber, and vitamin K. These nutrients protect against free radicals, they maintain proper blood circulation, and remove heavy metals that can damage the brain. Research also suggests that broccoli can help contribute to the brain healing itself in the event of an injury! That’s pretty powerful stuff for a vegetable.

Number 4 — Beets

They’re high in nitrates (硝酸盐), which help increase blood flow in parts of the brain related to executive functioning. Beets also contain lots of vitamin B9, which can aid cognitive functioning and delay dementia. In addition, beets are rich in carotenoids, which can help boost brain functioning and stave off depression.

Number 5 — Seeds

They contain a rich mix of protein, omega fatty acids, and B vitamins. These seeds also contain tryptophan, which the brain converts into serotonin to boost mood and combat depression. Eating a handful of seeds daily will also provide your daily recommended amount of zinc, which can help enhance memory and thinking skills! Soaked and sprouted seeds are even healthier!

Number 6 — Nuts

Nuts are a great source of omega 3 and omega 6 fatty acids, vitamin B6; and vitamin E, which has been shown to improve brain power and prevent many forms of dementia by protecting the brain from free radicals. Though it is worth noting, nuts contain some anti-nutrients - such as phytic acid, so it’s much healthier if you soak them overnight before you eat them.
