The brain requires a healthy food intake in order function efficiently.

Healthy foods are real food and mostly vegetables, fruits and berries.

Jim Kwik has in Limitless (2020) made a list of food for the brain:

“The Top 10 Brain Foods

Avocados: They provide monounsaturated fat, which helps to maintain healthy blood flow.

Blueberries: They protect your brain from oxidative stress and reduce the effects of brain aging. There have also been studies that show they can help with memory.

Broccoli: A great source of vitamin K, which is known to improve cognitive function and memory.

Dark chocolate: This helps your focus and your concentration and stimulates endorphins. Chocolate also has flavonoids, which have been shown to improve cognitive function. The darker here the better, as the darkest chocolate has the least sugar, and we´ve already talked about sugar is something to eat sparingly.

Eggs: They provide memory-improving and brain-boosting choline.

Green leafy vegetables: These are good sources of vitamin E, which reduces the effects of brain aging, and folate, which has been shown to improve memory.

Salmon, sardines, caviar: They´re rich in omega-3 essential fatty acids, which help reduce the effects of brain aging.

Turmeric: It helps reduce inflammation and boost antioxidant levels, while also improving your brain´s oxygen intake. There´s also some indication that turmeric helps reduce cognitive decay.

Walnuts: These nuts provide high levels of antioxidants and vitamin E that protect your neurons and protect against brain aging. They also contain high levels of zinc and magnesium, which are really good for your mood.

Water: Your brain is about 80 percent water. Dehydration can cause brain fog, fatigue, and slower reaction and thinking speed. Studies show that well-hydrated people score better on brain power tests.”1

“You can get a list of nutrients and their effect on the brain from the National Institutes of Health websites.”2
