Scientists at Wake Forest University in North Carolina have discovered that simply eating one beetroot a day can help fight Alzheimer’s.

This is due to its high levels of nitrates, which your mouth bacteria turns into nitrites. These chemicals dilate your blood vessels, increasing flow and oxygen delivery. The frontal lobes of the brain need this oxygen to prevent deterioration as you age, making beetroot the most impressive salad ingredient there is… as long as you don’t spill it down your front.
