Water: When a person
becomes dehydrated, their brain tissue actually shrinks. And several
studies have shown that dehydration can affect cognitive function.
Dehydration can impair short-term memory, focus and decision making.
Walnuts: are chock-full
of heart-healthy and anti-inflammatory nutrients, and are the only good
nut source of alpha linolenic acid. That means they help promote blood
flow, which in turn allows for efficient delivery of oxygen to the
brain.
Olive oil: is a great source of monounsaturated fats, which have been shown to actually slow brain ageing.
Sardines: Fatty fish
like sardines (and salmon!) are a well-known brain booster, thanks to
the omega-3 fatty acids, EPA and DHA, which have been linked to lower
risk of dementia, improved focus and memory.
Spinach:
is rich in the antioxidant lutein, which is thought to help protect
against cognitive decline. Again, women who reported eating the leafiest
green and cruciferous vegetables had a markedly lower rate of cognitive
decline, compared to those who ate the least.
Chocolate:
Antioxidant-rich dark chocolate is healthy for your whole body, but its
caffeine content is thought to play a role in maintaining mental acuity.
What’s more, chocolate is rich in flavonoids, a class of antioxidant
that helps to improve blood flow (and thus brain health) by regulating
cholesterol and lowering blood pressure.
Avocados: Avocados are full of monounsaturated fats that improve vascular health and blood flow, making them another brain food.
Garlic: Garlic may help
stave off some forms of brain cancer, according to a research published
in Cancer, the medical journal of the American Cancer Society.
Investigators found that the organo-sulfur compounds in garlic actually
worked to kill glioblastoma cells – a type of malignant tumour cell.
