Senior researcher Rhoda Au and her team performed the long-term health study on 1,400 adults, spanning 10 years.
Au concluded that those participants who ate diets packed with plenty of choline performed better in memory tests and were less likely to acquire brain changes associated with dementia than those who consumed less choline in their diets. However, Au noted that no one nutrient is a magic bullet against dementia.
Other foods high in choline include legumes (such as soy and kidney beans), saltwater fish, liver and milk.
Some studies have shown that eating fish rich in omega-3 fatty acids could help slow the typical cognitive decline that comes with age. In addition, a 2010 study concluded that tea drinkers did better on tests of memory and information processing than non-tea drinkers did.
